## Common questions
- **How much does a home addition cost in Ontario?** We price GTA home additions at about $350 to $600 per square foot in 2026, and a single-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000, before 13% HST. A second storey of 600 to 1,200 sq ft runs $300,000 to $800,000. Our pricing page lists every range and what moves it.
- **Is the estimate free?** Yes. The first estimate from Jarvis Contracting is free. Call James on (289) 892-4169 or send the enquiry form on our contact page to arrange it.
- **Do I need a building permit for an addition in Ontario?** Yes. Under section 8 of Ontario's Building Code Act, an addition needs a building permit from your municipality before work starts. If it breaks a zoning limit, such as a setback or height, it also needs a minor variance from the Committee of Adjustment first. We prepare the drawings and make the applications.
- **How long does the town take to issue a building permit?** The Ontario Building Code gives a municipality 10 business days to decide a complete permit application for a house without one unit above another, and 15 for most other small buildings. The clock starts only when the application is complete, and a minor variance has to be decided before that.
- **How long does a second-storey addition take?** Our West Lynde second storey, a bungalow taken to two storeys with a new kitchen and two bathrooms, took about four and a half months on site in Whitby in 2023. Design and the permit come before that, and a house that needs a minor variance waits for the committee of adjustment too.
- **How long does a larger renovation take from start to finish?** Greenwood, a rear extension and a new top floor on a Toronto house, took 10 months from the permit and the interior design through construction. Smaller jobs take less; you get a schedule with the contract.
- **Do you do the design yourselves?** Yes. Jarvis Contracting's design is run by James's wife through her studio, Juliette Interiors: she measures, draws the floor plans, builds a 3D model and presents your finishes to you in our office. Structural drawings come from a structural engineer, and on larger jobs we work with an architect.
- **Can I see the design before it's built?** Yes. Once the floor plans are settled, our designer builds a 3D model of the rooms with the textures and finishes in it, so you can see the kitchen or the new floor before anything is ordered.
- **Where does Jarvis Contracting work?** Jarvis Contracting is based in Ajax and works across Durham Region, Ontario and the Greater Toronto Area. The Areas page lists each town we serve, with its permit rules and fees.
- **Who will I deal with during the project?** James Jarvis on the build, from the first site visit to the handover, and our designer at Juliette Interiors on the design. You have one point of contact for the construction.

## How a job runs

James meets you at the house first, and the whole job is priced and signed before design starts. Then his wife, our designer, gets to know how your family lives, measures the house, draws the floor plans and builds a 3D model, and presents the finishes to you in our office, so nothing is ordered until you've seen the room. We prepare the drawings the permit needs and bring in a structural engineer wherever a beam or wall that carries weight changes. Then we build, with James as your one point of contact on site. Every step is on [our process page](https://www.jarviscontracting.ca/process).

## When we open a wall

Old houses hide things. On one main floor we renovated, it was asbestos on the pipes, plus risky wiring a previous owner had left behind, and the owners heard about each problem and what it would cost before anyone touched it. The job still finished on the agreed schedule. The owner, David Hayes, wrote that James "walked us through every issue that popped up" ([Google review](https://www.google.com/maps?cid=12439853613263293818), November 2025).

## What it costs

We price a home addition in the Greater Toronto Area at about $350 to $600 per square foot in 2026, and a second storey of 600 to 1,200 sq ft at $300,000 to $800,000, before HST. That's a range, not your quote: we price your job after a site visit, and the first estimate is free. Every service page has its ranges and what moves them, and our [pricing page](https://www.jarviscontracting.ca/pricing) puts them in one place.

## Where we work

We're based in Ajax, in Durham Region, east of Toronto, and work across Durham and the Greater Toronto Area. Each town's page carries its own permit rules and fees and the jobs we've finished nearby.

# How a project runs, from the first visit to handover

Ten steps, in the order they happen. You meet James first, the whole job is priced before design starts, you see the design in 3D before anything is ordered, and nothing is built until the permit is issued.

## The first estimate is free

James meets you at the house, hears what you want and gives you a rough estimate on the spot, and your first estimate costs nothing. Call him on (289) 892-4169 or send the [enquiry form](https://www.jarviscontracting.ca/contact).

## The order matters

The entire project is priced, and the contract signed, before any design work begins. James's proposals are detailed, so the price rarely moves; when a design selection or a finish does change it, the change goes through a change order you approve and sign. Our designer is James's wife, who runs the design studio Juliette Interiors, so the person drawing the plan knows what it costs to build.

## The steps

1. **Meet James.** James meets you at the house, hears what you want and gives you a rough estimate on the spot. The first estimate is free.
2. **Proposal and contract.** If the estimate works for you, James prepares a detailed proposal. The whole project is priced, and the contract signed with a 10% deposit, before any design work begins.
3. **Design onboarding.** Our designer sends you an onboarding email with some homework: your style, how your family uses the house, and what you need and want. You share Pinterest boards, then go through them together on a Zoom call: what you like in the pictures, and what you don't.
4. **Measure and floor plans.** The designer measures the house and draws the floor plan: which walls come out, where the stairs land, how new space joins the old. We go through it with you until it's confirmed.
5. **Drawings and 3D rendering.** With the plan confirmed, she draws the elevations and the millwork, then puts it all into a 3D rendering, so you see the rooms before anyone orders a cabinet.
6. **Finishes presentation.** We don't take you round the stores: there are too many options. Using what she learned in onboarding, the designer narrows the tile, flooring, quartz, plumbing fixtures and the rest to a few choices that suit your style, collects the samples and presents them to you in our office. If a selection changes the price, the change goes through a change order you sign.
7. **Permits and engineering.** We prepare the permit drawings, bring in the structural engineer wherever a beam or a load changes, and apply to the municipality. If the plan changes after the permit is issued, we file the amendment.
8. **Construction.** Our crew and trades build it, with one point of contact from demolition to the last coat of paint. Our site supervisors write a job log every day, which you can follow in our online app. When we open a wall and find a problem, you hear about it, and what it costs, before we fix it.
9. **Inspections.** The municipal building inspector checks the work at each stage the permit sets, before it gets covered up.
10. **Handover.** We walk the finished house with you and put right anything that isn't. On one job a stair stain didn't match the new floor, so we refinished the stairs.

## How long it takes

West Lynde, a bungalow taken to two storeys with a new kitchen and two bathrooms, took about four and a half months on site in Whitby in 2023. Greenwood, a rear extension and a new top floor in Toronto, took 10 months from the permit and the design through construction. The permit itself has a clock: for a house without one unit above another, the town has 10 business days to decide a complete application ([Ontario Building Code, Division C](https://www.publications.gov.on.ca/301880)).

## How you'll know what's happening

Our site supervisors write a job log every day to document progress, and you can read it in our online app. Clients have written about it: one loved "the on line app to track day to day progress with daily pictures" (Susan Morris, 2023), and another, who rarely saw the house, was "consistently kept ... updated with photos and videos" (George Sevastin, 2026), both on [Google](https://www.google.com/maps?cid=12439853613263293818).

## When the plan changes

Sometimes the house changes the plan. At Greenwood, once the demolition was done, taking out a brick wall in the basement made sense to gain floor space. That needed new engineering and an amendment to the permit, and it cost us a short delay. The same house had no waterproofing and no weeping tile at the footing, and little room to dig, so we installed a bridged weeping system that carries the water to a sump pump, which pumps it away from the house.

## Your rights under Ontario law

Ontario requires a written contract for any renovation over $50. If you sign at home, you have 10 days to cancel. And the final price can't be more than 10% over the estimate unless you agree to changes ([ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

# What additions and renovations cost in 2026

Our 2026 ranges for each kind of work we do, with what moves the number. They're ranges, not your quote: we price your job after a site visit, and the first estimate is free.

## How we price a job

We don't price from a chart. James sees the house and gives you a rough estimate on the spot, then a detailed proposal: the whole project is priced, and the contract signed, before any design work begins. Our contracts are fixed price. If a design selection or finish changes the price, the change goes through a change order you sign. Our guide to [fixed price and cost-plus](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus) explains the two ways contractors charge.

## What the ranges leave out

Unless a row says otherwise, every range here is before 13% HST. Our drawing prices are the drawings alone: permit fees, HVAC engineering, truss design, a committee of adjustment application and anything unforeseen are extra. Whoever you ask, check what their number includes.

## What Ontario law says about estimates

A renovation over $50 needs a written contract, and the final price can't exceed the estimate by more than 10% unless you agree to changes ([ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

## Home additions

What moves the number:
- Size and complexity
- Structural engineering
- A minor variance application
- How many design revisions

## Design-build

No single range: every job is priced after a site visit.

What moves the number:
- The scope you choose
- The finishes you pick with the designer
- Structural work
- 13% HST on top

## Where there's no range

Whole-home renovations and design-build projects vary too much for one range, so we don't print one. They're priced after James sees the house. The service pages list what drives each one.

# Licences, permits and warranties: what applies to your job

Which licences and protections apply depends on what you're building. This is what Ontario requires for each kind of work as of October 2026, with the regulator's page for each, so you can check any contractor, including us.

## Every job: the permit and the Building Code

Any job that needs a building permit gets one before work starts, and we build to the 2024 Ontario Building Code, in force since 1 January 2025 ([O. Reg. 163/24](https://www.ontario.ca/laws/regulation/r24163)). The town's inspector checks the work at each stage the permit sets. The approval is the town's to give, not ours.

## Additions and renovations: no HCRA licence, no Tarion

The Home Construction Regulatory Authority (HCRA) licenses builders of new homes. It says renovating or upgrading an existing home generally doesn't make it a new home, so a renovator needs no HCRA licence ([HCRA](https://www.hcraontario.ca/do-i-need-a-licence/)), and renovators "aren't licensed or regulated like new home builders" ([HCRA](https://www.hcraontario.ca/resources/finding-a-renovator/)). Tarion's warranty is for new homes. For an addition, a basement or a renovation, your protection is the written contract and whatever warranty the contractor puts in it.

## New homes and detached units: HCRA licence and Tarion

Building a new home for a client, even on the client's own land, needs an HCRA vendor and builder licence and Tarion enrolment, and HCRA says coach houses, laneway homes and tiny homes generally do too ([HCRA](https://www.hcraontario.ca/do-i-need-a-licence/)). Tarion's warranty on a contract home covers one, two and seven years up to $400,000, plus up to $40,000 if the builder defaults before completion ([Tarion](https://www.tarion.com/node/66068)). Look up any builder in the [Ontario Builder Directory](https://obd.hcraontario.ca/).

## Electrical and gas work

Only a licensed electrical contractor may do electrical work in your home, and they file a notification with the Electrical Safety Authority before starting; a general contractor isn't licensed for it ([ESA](https://esasafe.com/compliance/finding-the-right-contractor/)). Gas lines and appliances need a TSSA-certified fitter ([O. Reg. 212/01](https://www.ontario.ca/laws/regulation/010212)).

## WSIB

In construction, sole proprietors, partners and executive officers generally must carry WSIB coverage ([WSIB](https://www.wsib.ca/en/businesses/registration-and-coverage/expanded-compulsory-coverage-construction-industry)). An owner-operator doing only home renovation work directly for the person who lives there is exempt for themselves, but their workers and subcontractors must still be covered ([WSIB](https://www.wsib.ca/en/operational-policy-manual/expanded-compulsory-coverage-construction)). Anyone who hires a construction contractor directly must get a WSIB clearance certificate before work starts, except a homeowner hiring only for exempt home renovation work ([WSIB](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction)).

## Your contract

Ontario requires a written contract for any renovation over $50, gives you 10 days to cancel an agreement signed at home, and caps the final price at 10% over the estimate unless you agree to changes ([ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

## Credentials

- Written warranty: 1 year workmanship and materials, 2 years plumbing, heating, electrical and building envelope, 7 years structural
- BBB Accredited Business: Accredited by the Better Business Bureau since November 2025 (https://www.bbb.org/ca/on/ajax/profile/general-contractor/jarvis-contracting-inc-0107-1416595)
- Durham Region Home Builders' Association: Member, Renovators (https://www.drhba.com/Sys/PublicProfile/99587295/5125036)
- RenoMark: RenoMark renovator, through the DRHBA (https://renomark.ca/find-a-renovator/)

## Our written warranty

We give our own written warranty on the work we do:

- **One year** for defects in workmanship and materials.
- **Two years** for the plumbing, heating and electrical systems, and for water getting in through the building envelope.
- **Seven years** for structural defects.

The warranty is subject to normal homeowner maintenance. It doesn't cover damage from misuse, neglect, normal wear and tear, or alterations made by others. Every warranty claim must reach us in writing before its warranty period ends.

This is our warranty, given by Jarvis Contracting. It isn't Tarion's new-home warranty and isn't backed by Tarion; as the section above explains, Tarion doesn't cover additions or renovations.

## Where to check us

The Better Business Bureau lists Jarvis Contracting as accredited, rated A+, since 28 November 2025 ([BBB](https://www.bbb.org/ca/on/ajax/profile/general-contractor/jarvis-contracting-inc-0107-1416595)). We're a member of the Durham Region Home Builders' Association ([DRHBA member directory](https://www.drhba.com/Sys/PublicProfile/99587295/5125036)) and a RenoMark renovator through it ([RenoMark](https://renomark.ca/find-a-renovator/)), both from October 2026.

## Reviews

> Amazing work! We’ve worked with Jarvis Contracting twice now. Both times exceeded expectations. Thorough, concise, and professional.
> 
> Job 1 - Interior:
> 
> Upstairs flooring, closets, and new stairs were amazing. Our home is 125 years old - nothing is level. Challenges inevitably arise through reno’s. James and his team were detailed throughout the whole process with good communication and helped tackle any hurdles along the way.
> 
> Job 2 - Exterior:
> 
> New shed (it’s nice!), exterior stairs, and skirting around a deck. Outside is looking fresh.
> 
> The attention to detail is huge. The crew working on our home were courteous and friendly and my wife felt safe being home alone with them.
> 
> Highly recommend Jarvis Contracting! Can’t wait for our next project.

> 
> James and his team were professional, polite, efficient, and incredibly trustworthy throughout the project. Not only was the quality of the work excellent, but they actually finished ahead of schedule, which was a huge bonus. They also kept the worksite very clean and organized the entire time, which we greatly appreciated.
> 
> It’s not always easy to find contractors who are reliable, communicative, and take real pride in their work, but Jarvis Contracting absolutely delivered. We would not hesitate to use them again and highly recommend them to anyone looking for quality contracting and repair work.

Stephanie Lightowler, 5 out of 5 on [Google](https://www.google.com/maps?cid=12439853613263293818), about June 2026

> No matter the task, the Jarvis team was always up for the challenge. They went above and beyond, delivering high-quality work and even fixing issues that were not part of the initial agreement at no extra cost. Communication was impeccable, and even though I didn’t have the chance to visit the house often, they consistently kept me updated with photos and videos of the progress.

George Sevastin, 5 out of 5 on [Google](https://www.google.com/maps?cid=12439853613263293818), about April 2026

> We’re absolutely thrilled with the renovation of our main floor by Jarvis Contracting. James and his team were amazing to work with and were professional, friendly, and really skilled at what they do. The project was finished on time, even with a few unexpected surprises hiding behind our old walls, and with no sacrifice to the quality of workmanship.
> 
> James was upfront and honest from day one. He walked us through every issue that popped up (like finding asbestos on our pipes and some precarious electrical work from a previous owner) and clearly explained the costs and rationale behind each fix. We always felt informed and confident in the process.
> 
> Now that it’s all done, we couldn’t be happier. The space looks fantastic, and we have peace of mind knowing our home is safe. We’d highly recommend Jarvis Contracting to anyone planning a renovation, big or small. Great people, great work, and an incredible result!

David Hayes, 5 out of 5 on [Google](https://www.google.com/maps?cid=12439853613263293818), about November 2025

> We could not be happier following the main floor renovation of our new home by James and the Jarvis Contracting team! We decided to work with James after seeing his completed projects, receiving an exceptionally detailed quote & glowing references from other clients. Our renovation included removal of structural walls, relocation of the kitchen and fireplace, refinishing staircase & all new lighting & flooring throughout the home. The transformation is beautiful & amazing! Throughout the process, we had full confidence in James & the team who are very skilled and experienced with projects of this size/scope. Their problem solving ability, workmanship and attention to detail is excellent and I would highly recommend Jarvis Contracting for any renovation project you might be considering. We are so happy with the end result! Thanks James!

> My partner and I hired James and his team to renovate our new home; main floor kitchen, paint etc...To start, we are beyond ecstatic with the results. James is highly knowledgeable and always gave us options to help us remain on budget where possible. The quality of the work is a work of art and craftmanship. Most importantly, he and his team and a consistent mindset of always "getting it done right" and "getting it done perfectly" which we appreciated very much. He kept us informed along each milestone and ensured that we were aligned to every decision that had to be made and providing recommendations as well that may be beneficial for us. My partner and I can be very 'particular' and James was very accommodating on all aspects. Thank you James and your team for going above and beyond to ensure every detail is perfect. We couldn't be any happier with our home!

> I cannot say enough about James and his team. They are respectful, efficient, hard-working and thorough. We consulted James about our basement nightmare, renovated in 1997 as a play area for the kids and used as a huge storeroom from about 2003 to 2023. We kept intending to do something but could not pull the trigger. Finally in December 2023 we asked James to come take a look, along with some other contractors. Working with his designer, after speaking to us about what we liked and didn't like, they presented a plan that the moment we saw it achieved everything we wanted. Then he went ahead and did the job!! Everyone he brought in from plumbers, electricians, tile guys to drywall and tape guys to cabinet companies did everything they could to make us happy and bring that plan to life. We love our space now and have doubled the size of the living area in our home that brings us joy. The fact that James and Ceara bring the practical and the design together, and know how to achieve it, just eliminates so much stress and doubt in the process. So happy we went with Jarvis!

Tony O'Brien, 5 out of 5 on [Google](https://www.google.com/maps?cid=12439853613263293818), about 2 years before October 2026

> James and his crew are high quality contractors that get the job done. They finished our bathroom in a timely fashion. They take all of the guess work out and deliver a clean finished project. We will definitely be using them in future projects.

Rhys Aube, 5 out of 5 on [Google](https://www.google.com/maps?cid=12439853613263293818), about 2 years before October 2026

> This team is phenomenal! On time, professional, a lot of patience for our questions, and they really care about quality and the customer. We had a great experience

Nicole Bacci, 5 out of 5 on [Google](https://www.google.com/maps?cid=12439853613263293818), about 2 years before October 2026

> Great communication, very professional workers who are attentive to detail. The painter we hired was amazed at the quality work of the drywall installation. Our basement has been completely transformed. They had great suggestions for aesthetic appeal and consulted with us every step of the way. I would highly suggest working with jarvis, you won't be disappointed.

During April of 2017 my husband and I contracted Ian Jarvis of Jarvis Contraction Services to construct a wheelchair accessible bathroom in our basement. From start to finish we found Ian and James Jarvis to be very professional. Ian managed the project thoroughly with attention to detail. James has a great ability to balance both creativity and flexibility. We found them to be hard workers who demonstrated exceptional tradesman’s skills. The construction was completed on budget in a timely manner. The construction site and tracking areas were kept both safe and clean. All of the tradesmen introduced in association with Jarvis Contraction Services were highly skilled, and we appreciated the respectful manner. Ian and James satisfied all our expectations and more. Michele and Matthew Del Duca

> Ian was great. We worked with Ian to renovate two bathrooms. He did what he said he would do, how he said he would do it, within the time he estimated and at the cost he quoted. He is professional and capable, making suggestions and giving advice based on his depth of knowledge. We would not hesitate to hire him again for any job, big or small. I absolutely love both bathrooms, he did an amazing job, I can't believe they are the same rooms - they are transformed!!

> Jan 10th, 2016.  MASTER SUITE RENOVATION PROJECT.
> 
> I was hesitant to call this company as they did a lot of big Projects and I was looking for a simple washroom removing a regular bathtub and replacing it with a whirlpool-jaccuzi tub and a  stand-up shower with glass enclosure updating  the Faucets and  proper tiling using shluter System for my house in Pickering. From the outset,  IAN JARVIS was very professional. He was prompt, respectful, and very clear. Once we signed the contract, Ian Jarvis and his team were outstanding with a  project charter outlining everyones responsibility. They communicated with us on every level and every decision that needed to be made. The guys were professional, neat, and courteous. Timelines were met, and the quality of the work was great. I was thoroughly impressed with the way JARVIS CONTRACTING SERVICES does business. I strongly recommend this company, and I will definitely be using them when I am ready to do other Projects in the House.       Thank You  JCS  for making it  happen on time  and done right.

# A family practice. A personal approach.

Based in Ajax, Jarvis Contracting is James Jarvis and his wife. He runs construction; she runs design through her studio, Juliette Interiors. Together they design and build additions and renovations across Durham Region, Ontario and the GTA.

## Who we are

- **James Jarvis:** Owner, runs construction
- **Ceara, our designer at Juliette Interiors:** Designer, Juliette Interiors
- **Company:** Jarvis Contracting Inc.
- **Based in:** Ajax, Durham Region, Ontario
- **Founded:** 2007

## Who does what

James runs the build. He walks every house before we price it, runs the crew and the trades, and deals with the building department and the inspector. Our designer at Juliette Interiors runs the design: she measures, draws the floor plans and builds the 3D model, then narrows the finishes to a few that suit you and presents the samples in our office. Because they're married, the design and the build are worked out together.

## A note from James

I grew up on job sites. My grandfather was an architect and my dad started this business, so I learned early that a house is only as good as the parts you can't see.

Now I run the construction and my wife runs the design. She draws it, I build it, and neither of us is waiting on the other company to call back.

When you're working in an old house, you never know what's behind the wall until it's open. So when we find something, you hear what it is and what it costs before we fix it. On Bellamy we found asbestos, fire hazards and a point load in the basement, and we still handed the house back on the day we said we would.

If you can, do it all at once. It's faster, it's cleaner and it costs less than coming back later for the next room.

And if something we did isn't right, we fix it. On one job the stair stain didn't match the new floor. The homeowner had approved the colour, but neither of us liked it, so we refinished the stairs.

# Questions homeowners ask before they start

Cost, permits, timing, design and who does what, answered with the source for every number. Questions about one kind of work are on that service's page.

## Cost and quotes

### How much does a home addition cost in Ontario?

We price GTA home additions at about $350 to $600 per square foot in 2026, and a single-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000, before 13% HST. A second storey of 600 to 1,200 sq ft runs $300,000 to $800,000. Our pricing page lists every range and what moves it.

### Is the estimate free?

Yes. The first estimate from Jarvis Contracting is free. Call James on (289) 892-4169 or send the enquiry form on our contact page to arrange it.

### Are the prices on your site a quote?

No. They're our 2026 ranges for each kind of work. Jarvis Contracting prices your job after James has seen the house, because the same addition can cost very different amounts depending on the foundation, the structure and the finishes. The first estimate is free.

### Do you work fixed price or cost-plus?

Fixed price. Jarvis Contracting prices the whole project in a detailed proposal, and you sign the contract with a 10% deposit, before any design work begins. If a design selection or a finish changes the price, the change goes through a change order you sign. Our guide to fixed price and cost-plus explains how the two compare.

### Can a contractor charge more than the estimate in Ontario?

Not by much. Under Ontario's consumer protection rules, the final price of a renovation can't exceed the estimate by more than 10% unless you agree to changes, and any renovation over $50 needs a written contract.

## Permits and rules

### Do I need a building permit for an addition in Ontario?

Yes. Under section 8 of Ontario's Building Code Act, an addition needs a building permit from your municipality before work starts. If it breaks a zoning limit, such as a setback or height, it also needs a minor variance from the Committee of Adjustment first. We prepare the drawings and make the applications.

### How long does the town take to issue a building permit?

The Ontario Building Code gives a municipality 10 business days to decide a complete permit application for a house without one unit above another, and 15 for most other small buildings. The clock starts only when the application is complete, and a minor variance has to be decided before that.

### Can I add a basement apartment or a garden suite to my house?

Usually, on a serviced urban lot. Ontario's Planning Act lets you have up to three units without a rezoning: two in the house and one in a garden suite, or three in the house. Your town's zoning sets the size and setbacks, and some towns, such as Whitby, require the unit to be registered.

### Which building code applies to my project?

The 2024 Ontario Building Code has been in force since 1 January 2025, and every permit application made from 1 April 2025 must use it. We draw and build to it; the town's examiner and inspector check the work against it.

## Timing

### How long does a second-storey addition take?

Our West Lynde second storey, a bungalow taken to two storeys with a new kitchen and two bathrooms, took about four and a half months on site in Whitby in 2023. Design and the permit come before that, and a house that needs a minor variance waits for the committee of adjustment too.

### How long does a larger renovation take from start to finish?

Greenwood, a rear extension and a new top floor on a Toronto house, took 10 months from the permit and the interior design through construction. Smaller jobs take less; you get a schedule with the contract.

### What happens if you find a problem behind a wall?

We stop and tell you what we found and what it costs before we fix it. On one main floor that was asbestos on the pipes and risky wiring from a previous owner, and the job still finished on time. On Bellamy it was asbestos, fire hazards and a point load, and we handed the house back on the promised date.

## Design

### Do you do the design yourselves?

Yes. Jarvis Contracting's design is run by James's wife through her studio, Juliette Interiors: she measures, draws the floor plans, builds a 3D model and presents your finishes to you in our office. Structural drawings come from a structural engineer, and on larger jobs we work with an architect.

### Can I see the design before it's built?

Yes. Once the floor plans are settled, our designer builds a 3D model of the rooms with the textures and finishes in it, so you can see the kitchen or the new floor before anything is ordered.

### What is design-build?

Design-build is one firm designing your project and building it, so the plans are drawn by the people who price and build them instead of tendered to builders afterwards. At Jarvis Contracting the designer and the builder are a married couple.

## Working with us

### Where does Jarvis Contracting work?

Jarvis Contracting is based in Ajax and works across Durham Region, Ontario and the Greater Toronto Area. The Areas page lists each town we serve, with its permit rules and fees.

### Who will I deal with during the project?

James Jarvis on the build, from the first site visit to the handover, and our designer at Juliette Interiors on the design. You have one point of contact for the construction.

### Do renovators need a licence in Ontario?

No. The Home Construction Regulatory Authority licenses builders of new homes, not renovators: it says renovating an existing home generally doesn't make it new. Licences that do apply on a renovation are the electrical contractor's, through the Electrical Safety Authority, and a gas fitter's TSSA certificate.

### Is an addition covered by Tarion?

No. Tarion's warranty covers new homes, and the HCRA says a renovation or addition to an existing home generally doesn't make it a new home. For an addition, your protection is the written contract and the warranty it sets out.

### What warranty does Jarvis Contracting give?

Jarvis Contracting gives its own written warranty: one year for defects in workmanship and materials, two years for the plumbing, heating and electrical systems and for water coming in through the building envelope, and seven years for structural defects. It depends on normal homeowner maintenance, excludes misuse, neglect, wear and tear and other people's alterations, and claims must be made in writing within the period. It isn't a Tarion warranty.

# Home additions

Rear, side and garage additions, designed and built by one team so the new rooms look like they were always part of the house.

We price a home addition in the Greater Toronto Area (GTA) at about $350 to $600 per square foot in 2026, and a single-storey rear addition of 300 to 700 sq ft at about $180,000 to $450,000, before HST. We design the addition, draw the permit set and build it, from our office in Ajax across Durham Region, Ontario and the GTA.

## What's included

1. A site visit and measurements
2. Floor plans and a 3D model of the new rooms
3. Permit drawings, with structural engineering wherever loads change
4. The permit application, and any minor variance
5. Foundations, framing, the roof tie-in and exterior finishes
6. Interior finishes chosen with our designer
7. One point of contact from the first visit to handover

The kinds of job:

- Rear and side extensions
- Room additions and sunrooms
- In-law suites
- Garage additions and conversions
- Main-floor work in the same job

## Typical duration

Greenwood, a rear extension and a new top floor in Toronto, took 10 months including the permit, the design and construction.

## Permits involved

- A building permit from your municipality before work starts (Building Code Act, s. 8)
- A minor variance from the Committee of Adjustment when the design breaks a zoning limit such as a setback, height or lot coverage
- A conservation authority permit when the lot is in a regulated area near a stream, wetland or shoreline (Ontario Regulation 41/24)
- A heritage permit for exterior work in a Heritage Conservation District (Ontario Heritage Act, Part V)
- No development charges: enlarging an existing home doesn't trigger them (Development Charges Act, 1997)

## What it costs

| Work | Range (CAD) | Basis | Source |
|---|---|---|---|
| Home addition, any type | 350 to 600 per sq ft | GTA, 2026. Before 13% HST. | Our 2026 price |
| Single-storey rear addition, 300 to 700 sq ft | 180000 to 450000 | GTA, 2026. Before 13% HST. | Our 2026 price |
| Bump-out, 100 to 300 sq ft | 60000 to 180000 | GTA, 2026. Before 13% HST. | Our 2026 price |

What moves the number:
- The foundation: full basement, crawlspace or slab
- How much of the existing house opens up to join the new space
- The roof: new rafters meeting the old roof
- Engineering, drawings and the permit
- Finish level inside
- 13% HST, which these ranges leave out

## Finished jobs

- [Greenwood: a new top storey and rear extension in Toronto](https://www.jarviscontracting.ca/projects/greenwood): Toronto, 2026. Top floor replaced with a new storey, rear extension, basement enlarged, full interior design and build.
- [West Lynde: a Whitby bungalow made two storeys in 4.5 months](https://www.jarviscontracting.ca/projects/west-lynde): Whitby, 2023. New second storey of about 800 sq ft with two bedrooms, a walk-in closet and a bathroom; new kitchen, two new bathrooms, floors, stairs and trim below.
- [Custom Additions: rear extensions and garden rooms](https://www.jarviscontracting.ca/projects/custom-additions). A collection of rear additions, sunrooms and connections to the garden.

## Is it cheaper to build up or out?

It depends on what's underneath. Building out needs a new foundation; building up needs a foundation and walls strong enough to carry another floor, which a structural engineer checks before anything is drawn. Our guide to [building up or out](https://www.jarviscontracting.ca/guides/build-up-or-out) walks through both.

## Do I need a permit for an addition in Ontario?

Yes. Every addition needs a building permit from the municipality before work starts ([Building Code Act, s. 8](https://www.ontario.ca/laws/statute/92b23)), and as of October 2026 plans are reviewed under the 2024 Ontario Building Code, in force since 1 January 2025 ([O. Reg. 163/24](https://www.ontario.ca/laws/regulation/r24163)). If the addition breaks a zoning limit you also need a minor variance from the Committee of Adjustment. Since 21 November 2025, minimum setbacks on urban residential lots count as 90% of the zoning figure ([Ontario regulation](https://www.ontario.ca/laws/regulation/060545)), which sometimes removes the need for one.

## Does an addition pay development charges?

No. Enlarging an existing home doesn't trigger development charges under the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27). You pay the permit fee: in Whitby, $22.37 per square metre of new floor area in 2026 ([Town of Whitby fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)).

## Is it cheaper to add on or move?

Moving has its own price before you spend a dollar on space: land transfer tax, commission, legal fees and the move itself. Toronto buyers pay a municipal land transfer tax on top of the provincial one; Durham buyers pay the provincial tax only ([ontario.ca](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax)). Our [renovate or move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) does the arithmetic.

## How long does an addition take?

Greenwood, a rear extension and a new top floor on a Toronto house, took 10 months from the permit and the design through construction. A smaller single-storey addition takes less; we give you a schedule with the contract.

## Real work

Greenwood added a primary suite, a wet room under a skylight and a den with a balcony on a new top floor, plus a rear extension, and enlarged the basement by taking out a brick wall. That last change needed new engineering and a permit amendment, and cost us a short delay. See it in [our projects](https://www.jarviscontracting.ca/projects).

## Where we do this

Also in Ajax, Aurora, Brampton, Brock, Burlington, Caledon, Clarington, East Gwillimbury, Georgina, Halton Hills, King, Markham, Milton, Mississauga, Newmarket, Oakville, Oshawa, Pickering, Richmond Hill, Scarborough, Scugog, Toronto, Uxbridge, Vaughan, Whitby, Whitchurch-Stouffville.

## How the job runs

1. **Meet James.** James meets you at the house, hears what you want and gives you a rough estimate on the spot. The first estimate is free.
2. **Proposal and contract.** If the estimate works for you, James prepares a detailed proposal. The whole project is priced, and the contract signed with a 10% deposit, before any design work begins.
3. **Design onboarding.** Our designer sends you an onboarding email with some homework: your style, how your family uses the house, and what you need and want. You share Pinterest boards, then go through them together on a Zoom call: what you like in the pictures, and what you don't.
4. **Measure and floor plans.** The designer measures the house and draws the floor plan: which walls come out, where the stairs land, how new space joins the old. We go through it with you until it's confirmed.
5. **Drawings and 3D rendering.** With the plan confirmed, she draws the elevations and the millwork, then puts it all into a 3D rendering, so you see the rooms before anyone orders a cabinet.
6. **Finishes presentation.** We don't take you round the stores: there are too many options. Using what she learned in onboarding, the designer narrows the tile, flooring, quartz, plumbing fixtures and the rest to a few choices that suit your style, collects the samples and presents them to you in our office. If a selection changes the price, the change goes through a change order you sign.
7. **Permits and engineering.** We prepare the permit drawings, bring in the structural engineer wherever a beam or a load changes, and apply to the municipality. If the plan changes after the permit is issued, we file the amendment.
8. **Construction.** Our crew and trades build it, with one point of contact from demolition to the last coat of paint. Our site supervisors write a job log every day, which you can follow in our online app. When we open a wall and find a problem, you hear about it, and what it costs, before we fix it.
9. **Inspections.** The municipal building inspector checks the work at each stage the permit sets, before it gets covered up.
10. **Handover.** We walk the finished house with you and put right anything that isn't. On one job a stair stain didn't match the new floor, so we refinished the stairs.

## Questions

### Do I need a permit for a home addition in Ontario?

Yes. Any home addition in Ontario needs a building permit from your municipality before work starts, under section 8 of the Building Code Act. If the addition breaks a zoning limit, such as a setback or lot coverage, you also need a minor variance from the Committee of Adjustment first. We draw the plans and make both applications.

### How much does a home addition cost in the GTA?

We price GTA home additions at about $350 to $600 per square foot in 2026, and a single-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000, before 13% HST. The foundation, the structural work and the finishes move the number most. We price your addition after a site visit.

### Do home additions pay development charges in Ontario?

No. Ontario's Development Charges Act says enlarging an existing home doesn't trigger development charges, so a rear addition or a second storey pays the building permit fee but no development charges. Adding a second or third unit within the provincial limits is exempt too.

### Does a home addition need an HCRA licence or a Tarion warranty?

No. The Home Construction Regulatory Authority licenses builders of new homes, and it says renovating or adding to an existing home doesn't make it a new home. So an addition needs no HCRA licence and Tarion's new-home warranty doesn't cover it. Your protection is the written contract Ontario requires for any renovation over $50.

### Will the addition match the rest of the house?

A home addition should look like it was always there, and that starts in the drawings: rooflines, floor heights and finishes are drawn with the existing house. On our West Lynde job the drawn roof tie-in would have left low spots for water, so we built one single-slope roof instead.

# Second-storey additions

A second storey on a bungalow, starting with what the existing foundation and walls can carry.

We price a second-storey addition of 600 to 1,200 sq ft at $300,000 to $800,000 in 2026, before HST. Treat that as the new floor alone: a new kitchen or bathrooms on the floor below add to it. Our West Lynde job took a bungalow to two storeys, adding about 800 sq ft with two bedrooms and a walk-in closet, and redid the kitchen, bathrooms, floors and trim below, in about four and a half months on site in 2023.

## What's included

1. A structural check of the foundation and walls before design
2. Floor plans and a 3D model of the new floor
3. Permit drawings and structural engineering
4. Taking the roof off, framing the new floor and closing it in
5. Stairs, mechanicals, insulation and finishes
6. Main-floor work in the same job, if you want it

The kinds of job:

- Full second storeys on bungalows and backsplits
- A new roof designed with the new floor
- New stairs to the new floor
- Main-floor updates in the same job

## Typical duration

West Lynde, a Whitby bungalow taken to two storeys in 2023, took about four and a half months on site, mid-May to late September. Design and the permit come first.

## Permits involved

- A building permit from your municipality before work starts (Building Code Act, s. 8)
- Structural drawings from an engineer for the new loads
- A minor variance when the new height or lot coverage breaks the zoning
- A conservation authority permit when the lot is in a regulated area near a stream, wetland or shoreline (Ontario Regulation 41/24)
- No development charges: enlarging an existing home doesn't trigger them (Development Charges Act, 1997)

## What it costs

| Work | Range (CAD) | Basis | Source |
|---|---|---|---|
| Second-storey addition, 600 to 1,200 sq ft | 300000 to 800000 | GTA, 2026. The new floor; a kitchen or bathrooms below add to it. Before 13% HST. | Our 2026 price |

What moves the number:
- Whether the foundation and walls can carry the new floor, or need reinforcing
- A full storey or a partial one
- Whether the main floor is redone at the same time
- The roof design and how it meets what's left
- Engineering, drawings and the permit
- Finish level, and 13% HST on top

## Finished jobs

- [Greenwood: a new top storey and rear extension in Toronto](https://www.jarviscontracting.ca/projects/greenwood): Toronto, 2026. Top floor replaced with a new storey, rear extension, basement enlarged, full interior design and build.
- [West Lynde: a Whitby bungalow made two storeys in 4.5 months](https://www.jarviscontracting.ca/projects/west-lynde): Whitby, 2023. New second storey of about 800 sq ft with two bedrooms, a walk-in closet and a bathroom; new kitchen, two new bathrooms, floors, stairs and trim below.

## Can my bungalow take a second storey?

Often, but the answer comes from the foundation, not the floor plan. Before anything is drawn, a structural engineer checks whether the footings and walls can carry another floor, and if they can't, whether they can be reinforced.

## Should we redo the main floor at the same time?

Usually, yes. The new stairs land on the main floor and the pipes and ducts for the new floor run through it, so parts of it open up regardless. James's advice on every big job is to do it all at once: it's faster, cleaner and cheaper than coming back. At West Lynde the kitchen, both bathrooms, the floors, stairs and trim were redone inside the same four and a half months.

## How long does a second storey take?

West Lynde, in Whitby, ran from mid-May to the last week of September 2023: about four and a half months on site. Design and the permit come before that, and a house that needs a minor variance waits for the committee of adjustment too. We give you a schedule with the contract.

## Is a second storey cheaper than moving?

Compare it with what moving costs before you buy anything: land transfer tax (twice in Toronto, provincial and municipal), commission, legal fees and the move. On a $1.2 million Durham house the provincial land transfer tax alone is $20,475 at [Ontario's 2026 rates](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax). Our [renovate or move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) and [second-storey cost guide](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario) set the numbers side by side.

## Can a second storey get HST back?

Sometimes. The Canada Revenue Agency treats a major addition that at least doubles the living space, such as a full second storey on a bungalow, like a new home for the GST/HST new housing rebates ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). If construction starts between 1 April 2026 and 31 March 2027, Ontario's enhanced rebate may also apply ([CRA notice](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)). Our [HST relief guide](https://www.jarviscontracting.ca/guides/ontario-hst-relief-substantial-renovation) explains who qualifies; check with your accountant before you count on it.

## Questions

### Can you add a second storey to a bungalow?

A bungalow can take a second storey when its foundation and walls can carry the new floor, or can be reinforced to. A structural engineer checks the footings and walls first, and reinforcing adds cost. We get that answer before we spend your money on drawings.

### How much does a second-storey addition cost in Ontario?

We price a second-storey addition of 600 to 1,200 sq ft at $300,000 to $800,000 in 2026, before 13% HST. That's the new floor; a new kitchen or bathrooms on the floor below add to it. Your price comes after James sees the house, and the first estimate is free.

### How long does a second-storey addition take?

Our West Lynde second storey took about four and a half months on site, from mid-May to late September 2023. Design and the permit come first, and a house that needs a minor variance waits for the committee of adjustment hearing as well.

### Do you need a minor variance for a second storey?

A second storey needs a minor variance only when it breaks a zoning limit, most often height or lot coverage. In Whitby's main residential zones the height limit is 8.5 m under By-law 1784. A variance means a Committee of Adjustment hearing before the permit can be issued, so it adds months.

### Does a second-storey addition qualify for an HST rebate?

A second storey can qualify, but not on its own. The Canada Revenue Agency treats an addition that at least doubles a home's living space as a new home for the GST/HST new housing rebates only when the existing house is substantially renovated as part of the same project, and Ontario's enhanced relief covers construction that starts between 1 April 2026 and 31 March 2027. Check your case with an accountant before you count on it.

# Basement renovations

Finished basements and legal second units, built to the code the inspector checks.

We price basement finishing at about $55 to $90 per square foot in 2026, and a full legal basement apartment at $80,000 to $180,000, before HST. A legal unit has to meet the Ontario Building Code's rules for secondary suites, such as a 1.95 m ceiling and a fire separation between the units, and pass your town's inspections.

## What's included

1. A check of ceiling height, exits and windows before design
2. Floor plans and finishes with our designer
3. Permit drawings, and the application for a second unit
4. Fire separation and sound between units
5. Egress windows and separate entrances
6. Bathrooms, wet bars and laundry

The kinds of job:

- Basement finishing: rec rooms, bedrooms, bathrooms, bars and laundry
- Legal second units
- Separate entrances and walkouts
- Opening up a basement by moving walls

## Typical duration

Set after the first site visit.

## Permits involved

- A building permit for a second unit, and for plumbing or structural work
- The Building Code's secondary-suite rules: ceiling heights and a fire separation between units
- Registration of the unit where the town requires it, such as Whitby
- No development charges for a second or third unit in an existing house
- Electrical work by a licensed electrical contractor, who files a notification with the Electrical Safety Authority

## What it costs

| Work | Range (CAD) | Basis | Source |
|---|---|---|---|
| Full legal basement apartment | 80000 to 180000 | 2026. Before 13% HST. | Our 2026 price |
| Basement bathroom | 25000 to 50000 | 2026; the top end when new plumbing goes under the slab. Before 13% HST. | Our 2026 price |
| Basement finishing | 55 to 90 per sq ft | 2026, by finish level. Before 13% HST. | Our 2026 price |
| Legalising an already-finished basement | 45000 to 95000 | 2026. Before 13% HST. | Our 2026 price |
| Separate side-door entrance | 18000 to 28000 | 2026. Before 13% HST. | Our 2026 price |
| Underpinning the full perimeter | 60000 to 120000 | 2026, when the ceiling is too low. Before 13% HST. | Our 2026 price |

What moves the number:
- Ceiling height, and whether the floor has to be lowered or underpinned
- A second unit or not: fire separation, a second exit, a kitchen
- A separate entrance or a walkout
- Bathrooms and how far the plumbing runs
- Moisture or water damage found when the walls open
- Finish level, and 13% HST on top

## Is it legal, or just finished?

A finished basement is a renovation. A legal second unit is a permitted, inspected apartment that meets the Building Code's secondary-suite rules: ceilings at least 1.95 m, 1.85 m under beams and ducts, and a fire separation between the units, which can be a continuous smoke-tight layer of 15.9 mm Type X drywall ([2024 Building Code Compendium](https://www.publications.gov.on.ca/301880)). Turning one unit into two needs a permit even if you build nothing ([Building Code Act](https://www.ontario.ca/laws/statute/92b23)). Our [legal basement requirements guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario) lists the rest.

## What does a legal basement apartment cost?

A full legal basement apartment runs $80,000 to $180,000 with us in 2026, and legalising a basement that's already finished about $45,000 to $95,000, before HST. A separate side entrance is about $18,000 to $28,000 on its own, and a bathroom $25,000 to $50,000, more when new plumbing goes under the slab. Our [legal basement cost guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) breaks it down.

## Does a basement apartment pay development charges?

No. A second or third unit inside an existing house is exempt from development charges ([Development Charges Act](https://www.ontario.ca/laws/statute/97d27)). Some towns ask you to register it: Whitby charges $268 ([Town of Whitby](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)).

## Do I need a permit to finish my basement?

Your town's building department decides, and the answer turns on what you're building: a second unit always needs one, and so does plumbing or structural work. Our [basement permit guide](https://www.jarviscontracting.ca/guides/basement-permits-durham-region) covers each Durham town.

## Real work

Stone Ridge, in Scarborough, is a finished basement with a rec room and panelled media wall, an arched wet bar, a bathroom, a laundry and a bedroom. One client, whose basement had been a storeroom for twenty years, wrote that the job "doubled the size of the living area in our home" (Tony O'Brien, Google review).

## Where we do this

Also in Ajax, Aurora, Brampton, Brock, Burlington, Caledon, Clarington, East Gwillimbury, Georgina, Halton Hills, King, Markham, Milton, Mississauga, Newmarket, Oakville, Oshawa, Pickering, Richmond Hill, Scarborough, Scugog, Toronto, Uxbridge, Vaughan, Whitby, Whitchurch-Stouffville.

## How the job runs

1. **Meet James.** James meets you at the house, hears what you want and gives you a rough estimate on the spot. The first estimate is free.
2. **Proposal and contract.** If the estimate works for you, James prepares a detailed proposal. The whole project is priced, and the contract signed with a 10% deposit, before any design work begins.
3. **Design onboarding.** Our designer sends you an onboarding email with some homework: your style, how your family uses the house, and what you need and want. You share Pinterest boards, then go through them together on a Zoom call: what you like in the pictures, and what you don't.
4. **Measure and floor plans.** The designer measures the house and draws the floor plan: which walls come out, where the stairs land, how new space joins the old. We go through it with you until it's confirmed.
5. **Drawings and 3D rendering.** With the plan confirmed, she draws the elevations and the millwork, then puts it all into a 3D rendering, so you see the rooms before anyone orders a cabinet.
6. **Finishes presentation.** We don't take you round the stores: there are too many options. Using what she learned in onboarding, the designer narrows the tile, flooring, quartz, plumbing fixtures and the rest to a few choices that suit your style, collects the samples and presents them to you in our office. If a selection changes the price, the change goes through a change order you sign.
7. **Permits and engineering.** We prepare the permit drawings, bring in the structural engineer wherever a beam or a load changes, and apply to the municipality. If the plan changes after the permit is issued, we file the amendment.
8. **Construction.** Our crew and trades build it, with one point of contact from demolition to the last coat of paint. Our site supervisors write a job log every day, which you can follow in our online app. When we open a wall and find a problem, you hear about it, and what it costs, before we fix it.
9. **Inspections.** The municipal building inspector checks the work at each stage the permit sets, before it gets covered up.
10. **Handover.** We walk the finished house with you and put right anything that isn't. On one job a stair stain didn't match the new floor, so we refinished the stairs.

## Questions

### What makes a basement apartment legal in Ontario?

A legal basement apartment in Ontario has a building permit, passed its inspections and meets the Building Code's secondary-suite rules, including minimum ceiling heights and a fire separation between the units. Some towns, such as Whitby, also require the unit to be registered.

### What ceiling height does a basement apartment need in Ontario?

The 2024 Ontario Building Code requires ceilings of at least 1.95 m in a secondary suite, with at least 1.85 m of clear height under beams and ducts. Basements lower than that need the floor lowered or the walls underpinned before they can become a legal unit.

### How much does a legal basement apartment cost in Ontario?

We price a full legal basement apartment at $80,000 to $180,000 in 2026, and legalising an already-finished basement at about $45,000 to $95,000, before HST. A separate entrance adds about $18,000 to $28,000 on its own, and underpinning more again.

### Do I pay development charges on a basement apartment?

No. Ontario's Development Charges Act exempts a second or third unit created inside an existing house, within the three-unit limits. You still pay the building permit fee, and in towns like Whitby a registration fee of $268.

# Whole-home renovations

Whole floors and whole houses: walls out, structure fixed, old systems replaced and finished as one project.

We found no published cost range for a whole-home renovation in the GTA that we'd stand behind as of October 2026, so we don't print one: yours is priced after James sees the house. What we can show is the work. At Bellamy, a brick bungalow, we took out the load-bearing walls with steel beams, had the asbestos removed, fixed the fire hazards we found, and handed the house back on the date we'd promised.

## What's included

1. Floor plans and a 3D model
2. Structural engineering for walls that come out
3. Steel beams and point loads
4. Plumbing, wiring and ductwork rerouted, behind false walls where needed
5. Asbestos and old wiring handled by the right trades
6. Floors, stairs, trim, kitchens and bathrooms

The kinds of job:

- Open-concept main floors
- Full-floor and whole-house renovations
- Older homes: levelling floors, rewiring, rebuilding stairs
- Kitchens and bathrooms as part of the whole

## Typical duration

Set after the first site visit.

## Permits involved

- A building permit for structural changes, such as taking out a load-bearing wall
- Electrical work by a licensed electrical contractor, who files a notification with the Electrical Safety Authority
- Gas lines and appliances by a TSSA-certified gas fitter
- A heritage permit for exterior work in a Heritage Conservation District (Ontario Heritage Act, Part V)

## What it costs

No single range for this work.

What moves the number:
- How much of the house changes
- Load-bearing walls, and the beams that replace them
- What's behind the walls: asbestos, knob-and-tube wiring, water damage
- Hiding pipes and ducts without bulkheads
- Finish level, and 13% HST on top

## Finished jobs

- [Greenwood: a new top storey and rear extension in Toronto](https://www.jarviscontracting.ca/projects/greenwood): Toronto, 2026. Top floor replaced with a new storey, rear extension, basement enlarged, full interior design and build.
- [Solace: a home gutted to the studs and rebuilt inside](https://www.jarviscontracting.ca/projects/solace): Toronto, 2026. Complete gut to the studs, load-bearing walls removed and reframed, spray foam throughout, new upstairs washroom, full interior design.
- [Syncopa: steel beams, a new layout and three new bathrooms](https://www.jarviscontracting.ca/projects/syncopa): North York, Toronto, 2026. Permits, steel beams, layout reworked, stone fireplace out, three new bathrooms, new doors, floors, trim and tile, attic insulation upgraded.
- [Bellamy: opening up a brick bungalow without an addition](https://www.jarviscontracting.ca/projects/bellamy): Scarborough, Toronto, 2025. Whole main floor: load-bearing walls out, steel beams in, new kitchen, mudroom, office, fireplace, floors, trim and doors.
- [Orra: two load-bearing walls out of a childhood home](https://www.jarviscontracting.ca/projects/orra): Ajax, 2025. Two load-bearing walls out, kitchen and living room swapped, gas fireplace with built-ins, new floors, doors and trim, popcorn ceilings removed.
- [West Lynde: a Whitby bungalow made two storeys in 4.5 months](https://www.jarviscontracting.ca/projects/west-lynde): Whitby, 2023. New second storey of about 800 sq ft with two bedrooms, a walk-in closet and a bathroom; new kitchen, two new bathrooms, floors, stairs and trim below.

## Renovate or add on?

Sometimes the space is already there. The Bellamy owners wanted a bigger house without an addition, so we took out the interior walls and opened the main floor end to end. Our [renovate or move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) helps with the bigger question.

## What happens when you open the walls?

In an older house you find things. At Aurelia, a Toronto house about 100 years old, the floor was out of level, there was water damage and the wiring was knob and tube; all of it was replaced. You hear about each one, with the cost, before we fix it. One client wrote that James "walked us through every issue that popped up" (David Hayes, Google review).

## Should we do it all at once?

If you can, yes. Doing everything in one job is faster, cleaner and cheaper than a room a year, because the walls, floors and trades are only opened and paid for once. At Orra we hid the new ductwork and plumbing behind a false wall so the open main floor has no bulkheads.

## Who does the electrical and gas work?

Licensed trades. In Ontario only a licensed electrical contractor may do electrical work in your home, and they file a notification with the Electrical Safety Authority ([ESA](https://esasafe.com/compliance/finding-the-right-contractor/)). Gas work needs a TSSA-certified fitter ([O. Reg. 212/01](https://www.ontario.ca/laws/regulation/010212)).

## Where we do this

Also in Ajax, Aurora, Brampton, Brock, Burlington, Caledon, Clarington, East Gwillimbury, Georgina, Halton Hills, King, Markham, Milton, Mississauga, Newmarket, Oakville, Oshawa, Pickering, Richmond Hill, Scarborough, Scugog, Toronto, Uxbridge, Vaughan, Whitby, Whitchurch-Stouffville.

## Questions

### How much does a whole-home renovation cost?

We haven't found a published GTA range for whole-home renovations that we trust, so we don't quote one. The cost depends on how much of the house changes, the structural work, what's behind the walls and the finishes. We price yours after a site visit, before design starts.

### Can you remove a load-bearing wall?

Yes. A load-bearing wall comes out once an engineer has sized the steel beam that replaces it and the point loads that carry the beam down to the foundation, and once the building permit is issued. We did this on the Bellamy and Orra main floors.

### What happens if you find asbestos or old wiring?

We stop, tell you what we found and what it costs to fix, and bring in the right trade. On Bellamy we found asbestos and fire hazards, had the asbestos removed safely and fixed the hazards, and still finished on the promised date.

### Who does the electrical work in a renovation?

In Ontario only a licensed electrical contractor may do electrical work in your home, and they must file a notification with the Electrical Safety Authority before starting. General contractors aren't licensed for it, so we bring in a licensed electrician.

# Kitchen renovations

Kitchens planned around how you cook, including the walls that need to move to get there.

We price a mid-range kitchen renovation at about $40,000 to $75,000 before HST in 2026, and a premium one at $85,000 to $150,000. Ours start with our designer at Juliette Interiors: a floor plan, then a 3D model with the finishes in it, then a finishes presentation in our office, so you choose cabinets after you've seen them in the room. We don't have a showroom; we can show you past projects in person.

## What's included

1. A layout and a 3D model of the finished kitchen
2. Cabinets, counters, backsplash and hardware chosen with the designer
3. Walls opened with engineered beams where needed
4. Plumbing, electrical and lighting
5. Flooring carried through to the rest of the floor

The kinds of job:

- Full kitchen renovations
- Opening a kitchen to the living space
- Moving the kitchen to another part of the house
- Custom details: curved hoods, islands, built-ins

## Typical duration

Set after the first site visit.

## Permits involved

- A building permit when walls, plumbing or structure change
- Electrical work by a licensed electrical contractor, who files a notification with the Electrical Safety Authority
- Gas lines and appliances by a TSSA-certified gas fitter

## What it costs

| Kitchen renovation, mid-range | 40000 to 75000 | 2026. Before 13% HST. | Our 2026 price |
| Kitchen renovation, premium | 85000 to 150000 | 2026. Before 13% HST. | Our 2026 price |

What moves the number:
- Moving the sink, the range or a wall
- Cabinets: stock, semi-custom or custom
- Counters and stone
- Appliances
- Structural work when walls come out
- 13% HST on top

## What does a kitchen renovation cost in 2026?

About $40,000 to $75,000 for a mid-range kitchen with us, and $85,000 to $150,000 for a premium one, before HST. Moving walls or plumbing, custom cabinets and stone counters push a kitchen up the range. Whoever you ask, check what the quote includes: walls, flooring, lighting, appliances and HST.

## Do I need a permit to renovate a kitchen?

New cabinets and counters alone, usually not; moving walls, plumbing or structure, yes. Your municipality's building department decides. Electrical work goes through a licensed electrician and the Electrical Safety Authority ([ESA](https://esasafe.com/compliance/finding-the-right-contractor/)), and a gas range through a TSSA-certified fitter.

## Real work

1. **Meet James.** James meets you at the house, hears what you want and gives you a rough estimate on the spot. The first estimate is free.
2. **Proposal and contract.** If the estimate works for you, James prepares a detailed proposal. The whole project is priced, and the contract signed with a 10% deposit, before any design work begins.
3. **Design onboarding.** Our designer sends you an onboarding email with some homework: your style, how your family uses the house, and what you need and want. You share Pinterest boards, then go through them together on a Zoom call: what you like in the pictures, and what you don't.
4. **Measure and floor plans.** The designer measures the house and draws the floor plan: which walls come out, where the stairs land, how new space joins the old. We go through it with you until it's confirmed.
5. **Drawings and 3D rendering.** With the plan confirmed, she draws the elevations and the millwork, then puts it all into a 3D rendering, so you see the rooms before anyone orders a cabinet.
6. **Finishes presentation.** We don't take you round the stores: there are too many options. Using what she learned in onboarding, the designer narrows the tile, flooring, quartz, plumbing fixtures and the rest to a few choices that suit your style, collects the samples and presents them to you in our office. If a selection changes the price, the change goes through a change order you sign.
7. **Permits and engineering.** We prepare the permit drawings, bring in the structural engineer wherever a beam or a load changes, and apply to the municipality. If the plan changes after the permit is issued, we file the amendment.
8. **Construction.** Our crew and trades build it, with one point of contact from demolition to the last coat of paint. Our site supervisors write a job log every day, which you can follow in our online app. When we open a wall and find a problem, you hear about it, and what it costs, before we fix it.
9. **Inspections.** The municipal building inspector checks the work at each stage the permit sets, before it gets covered up.
10. **Handover.** We walk the finished house with you and put right anything that isn't. On one job a stair stain didn't match the new floor, so we refinished the stairs.

## Questions

### How much does a kitchen renovation cost in Toronto?

We price a mid-range kitchen at about $40,000 to $75,000 and a premium one at $85,000 to $150,000 in 2026, before 13% HST. Moving walls or plumbing, custom cabinets and stone counters push a kitchen up the range.

### Do I need a permit to renovate my kitchen in Ontario?

A kitchen renovation needs a building permit in Ontario when it moves walls, plumbing or structure; your municipality's building department decides. New electrical work must be done by a licensed electrical contractor who notifies the Electrical Safety Authority.

### Can you move my kitchen to another part of the house?

Yes, with the plumbing, venting and any walls planned in the drawings first. On one main floor we relocated the kitchen and the fireplace and took out structural walls, and at Orra we swapped the kitchen and the living room.

### Who designs the kitchen?

Our designer at Juliette Interiors draws the layout, builds the 3D model and presents the finishes to you in our office, with the samples in front of you. James's crew builds what she draws, so the design and the build are priced and planned together.

# Bathroom renovations

Bathrooms with the waterproofing done under the tile, and layouts that fit the room you have.

We price a basement bathroom at $25,000 to $50,000 in 2026, before HST; the top end is when new plumbing has to go under the slab. Main-floor bathrooms and ensuites vary too much for one range, so yours is priced after a site visit. We've built ensuites with walk-in showers, a wet room under a skylight and a wheelchair-accessible basement bathroom.

## What's included

1. A layout and 3D model
2. Waterproofing behind and under the tile
3. Tile, vanity, glass and fixtures chosen with the designer
4. Plumbing, venting and electrical
5. Accessible layouts when you need them

The kinds of job:

- Ensuites and main bathrooms
- Basement bathrooms
- Powder rooms
- Wet rooms and walk-in showers
- Accessible bathrooms

## Typical duration

Set after the first site visit.

## Permits involved

- A building permit when a bathroom is added or drains move
- Electrical work by a licensed electrical contractor, who files a notification with the Electrical Safety Authority

## What it costs

| Work | Range (CAD) | Basis | Source |
|---|---|---|---|
| Basement bathroom | 25000 to 50000 | 2026; the top end when new plumbing goes under the slab. Before 13% HST. | Our 2026 price |

What moves the number:
- Moving the toilet, shower or drain
- Tile: size, pattern and how much of the room it covers
- Vanity, glass and fixtures
- Water damage under the old floor
- 13% HST on top

## Finished jobs

- [Aurelia: a fast kitchen and bath renovation in old Toronto](https://www.jarviscontracting.ca/projects/aurelia): Toronto, 2026. Kitchen, refinished stair, fluted fireplace, levelled floors, rewiring and a bathroom added mid-job.
- [Greenwood: a new top storey and rear extension in Toronto](https://www.jarviscontracting.ca/projects/greenwood): Toronto, 2026. Top floor replaced with a new storey, rear extension, basement enlarged, full interior design and build.
- [Solace: a home gutted to the studs and rebuilt inside](https://www.jarviscontracting.ca/projects/solace): Toronto, 2026. Complete gut to the studs, load-bearing walls removed and reframed, spray foam throughout, new upstairs washroom, full interior design.
- [Syncopa: steel beams, a new layout and three new bathrooms](https://www.jarviscontracting.ca/projects/syncopa): North York, Toronto, 2026. Permits, steel beams, layout reworked, stone fireplace out, three new bathrooms, new doors, floors, trim and tile, attic insulation upgraded.
- [West Lynde: a Whitby bungalow made two storeys in 4.5 months](https://www.jarviscontracting.ca/projects/west-lynde): Whitby, 2023. New second storey of about 800 sq ft with two bedrooms, a walk-in closet and a bathroom; new kitchen, two new bathrooms, floors, stairs and trim below.
- [Stone Ridge: a finished basement in Scarborough](https://www.jarviscontracting.ca/projects/stone-ridge): Scarborough, Toronto. Full basement finish: rec room, media wall, arched wet bar, bathroom, laundry room and bedroom.

## Do I need a permit for a bathroom renovation?

Replacing fixtures where they are, usually not. Adding a bathroom or moving drains does need one, and your municipality's building department decides. Electrical work goes through a licensed electrician who notifies the Electrical Safety Authority ([ESA](https://esasafe.com/compliance/finding-the-right-contractor/)).

## How long does a bathroom take?

It depends on the room and on what's under the old floor. On Aurelia the owners added an upstairs bathroom halfway through the job, and it was designed, selected and built in a couple of weeks so they could move in with their newborn.

## Real work

Greenwood: a primary ensuite and a wet room under a skylight on the new top floor, and a curved micro-cement vanity in the powder room. West Lynde: emerald tile with a gold edge over a hex floor. Stone Ridge: a basement bathroom with a checkerboard floor.

## Where we do this

Also in Ajax, Aurora, Brampton, Burlington, Caledon, Clarington, East Gwillimbury, Halton Hills, King, Markham, Milton, Mississauga, Newmarket, Oakville, Oshawa, Pickering, Richmond Hill, Scarborough, Scugog, Toronto, Uxbridge, Vaughan, Whitby, Whitchurch-Stouffville.

## Questions

### How much does a bathroom renovation cost in Toronto?

We price a basement bathroom at $25,000 to $50,000 in 2026, before HST, with the top end when new plumbing goes under the slab. Main-floor bathrooms and ensuites are priced after a site visit: tile, fixtures and moving the drains decide most of the cost.

### Do I need a permit to renovate a bathroom in Ontario?

A bathroom renovation in Ontario needs a building permit when it adds a bathroom or moves drains and plumbing; replacing fixtures in place usually doesn't. Your municipality's building department makes the call, and electrical work goes through a licensed electrician.

### Can you build an accessible bathroom?

Yes. The family firm built a wheelchair-accessible bathroom in a client's basement in 2017, and an accessible layout is drawn and modelled in 3D like any other bathroom before work starts.

### How long does a bathroom renovation take?

A bathroom renovation's length depends on the room and on what's found under the old floor. On our Aurelia job the owners added an upstairs bathroom halfway through, and we designed, selected and built it in a couple of weeks.

# Architectural design and permit drawings

Floor plans, 3D models and permit drawings from the team that will build them, so the plans are drawn by people who know what they cost to build.

Our permit drawings cost $6,000 to $12,000 for an addition, $4,000 to $8,000 for a basement apartment and $5,000 to $15,000 for a garden suite in 2026, before HST. That's the drawings: permit fees, HVAC engineering, truss design, a committee of adjustment application and anything unforeseen are extra. Since 1 April 2025 every permit application uses the 2024 Ontario Building Code ([O. Reg. 163/24](https://www.ontario.ca/laws/regulation/240163)), and for a house without one unit above another the town has 10 business days to decide a complete application ([Building Code, Division C](https://www.publications.gov.on.ca/301880)).

## What's included

1. Measured drawings of the existing house
2. Floor plans, revised with you
3. A 3D model with finishes
4. Permit drawings and the application
5. Structural engineering, coordinated with the engineer
6. Answers to the examiner, and amendments if the plan changes

The kinds of job:

- Additions and second storeys
- Additional units and basement apartments
- Whole-home and main-floor layouts
- Kitchens and bathrooms

## Typical duration

Set after the first site visit.

## Permits involved

- The building permit application the drawings support
- A minor variance application to the Committee of Adjustment where the design needs one
- The 2024 Ontario Building Code, required for every application since 1 April 2025

## What it costs

| Work | Range (CAD) | Basis | Source |
|---|---|---|---|
| Permit drawings for an addition | 6000 to 12000 | 2026. Drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra. Before 13% HST. | Our 2026 price |
| Permit drawings for a basement apartment | 4000 to 8000 | 2026. Drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra. Before 13% HST. | Our 2026 price |
| Permit drawings for a garden suite | 5000 to 15000 | 2026. Drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra. Before 13% HST. | Our 2026 price |

What moves the number:
- Size and complexity
- Structural engineering
- A minor variance application
- How many design revisions

## Why have the builder draw the plans?

Because the person drawing the roof is the person who has to build it. At West Lynde the drawn roof tie-in would have left low spots for water and ice, so we built one single-slope roof instead. Plans drawn without a builder get priced only at tender, and that's when they can come back over budget. Our guide to [design-build or a general contractor](https://www.jarviscontracting.ca/guides/design-build-vs-general-contractor) weighs both routes.

## What do you draw?

Measured drawings of the house as it stands, floor plans we revise with you, a 3D model with the finishes in it, and the permit set. Structural drawings come from a structural engineer, and on larger jobs we work with an architect.

## How long does the permit take?

The clock starts only when the application is complete: the provincial form, every schedule, the fees and the drawings ([Building Code, Division C](https://www.publications.gov.on.ca/301880)). The 10 days are business days. A house with a basement apartment probably falls in the 15-day category; your town confirms it. We answer the examiner's questions and file amendments if the plan changes.

## Do your drawings meet the Building Code?

We draw to the 2024 Ontario Building Code and your town's zoning. The town's plans examiner checks them and issues the permit; that sign-off is theirs, not ours.

## Where we do this

Also in Ajax, Aurora, Brampton, Burlington, Caledon, Clarington, East Gwillimbury, Halton Hills, King, Markham, Milton, Mississauga, Newmarket, Oakville, Oshawa, Pickering, Richmond Hill, Scarborough, Scugog, Toronto, Uxbridge, Vaughan, Whitby, Whitchurch-Stouffville.

## Questions

### How much do permit drawings cost in Ontario?

Our permit drawings cost $6,000 to $12,000 for an addition, $4,000 to $8,000 for a basement apartment and $5,000 to $15,000 for a garden suite in 2026, before HST. Permit fees, HVAC engineering, truss design, a committee of adjustment application and anything unforeseen are extra.

### How long does a building permit take in Ontario?

Under the Ontario Building Code, a municipality has 10 business days to decide a complete permit application for a house without one unit above another, and 15 for most other small buildings, which probably includes a house with a basement apartment. The clock starts only once the application is complete.

### Which building code applies to my project?

The 2024 Ontario Building Code has been in force since 1 January 2025, and every permit application made from 1 April 2025 must use it. Older permits issued under the 2012 Code keep it only if construction started within six months.

### Who approves the drawings?

Your municipality's plans examiner reviews the drawings against the Building Code and the zoning by-law, then issues the permit. We draw to both and answer the examiner's questions, but the approval is the town's.

# Design-build

One team from the first sketch to the keys: James runs construction, his wife runs design, and both work from the same plan.

Design-build means one firm designs your project and builds it. Here the two halves are a married couple: James Jarvis runs construction, and his wife runs design through her studio, Juliette Interiors. Greenwood in Toronto, a rear extension and a new top floor, went from the permit and the design through construction in 10 months that way.

## What's included

1. Consultation and measurements
2. Floor plans and a 3D model
3. Selections with the designer
4. Permit drawings, engineering and the permit
5. Construction, inspections and handover
6. One point of contact throughout

The kinds of job:

- Additions and second storeys
- Whole-home and main-floor renovations
- Kitchens, bathrooms and basements
- Additional units

## Typical duration

Greenwood, a rear extension and a new top floor in Toronto, took 10 months including the permit, the design and construction.

## Permits involved

- Whatever the project needs, applied for and managed by us

## What it costs

No single range for this work.

What moves the number:
- The scope you choose
- The finishes you pick with the designer
- Structural work
- 13% HST on top

## Finished jobs

- [Aurelia: a fast kitchen and bath renovation in old Toronto](https://www.jarviscontracting.ca/projects/aurelia): Toronto, 2026. Kitchen, refinished stair, fluted fireplace, levelled floors, rewiring and a bathroom added mid-job.
- [Greenwood: a new top storey and rear extension in Toronto](https://www.jarviscontracting.ca/projects/greenwood): Toronto, 2026. Top floor replaced with a new storey, rear extension, basement enlarged, full interior design and build.
- [Solace: a home gutted to the studs and rebuilt inside](https://www.jarviscontracting.ca/projects/solace): Toronto, 2026. Complete gut to the studs, load-bearing walls removed and reframed, spray foam throughout, new upstairs washroom, full interior design.
- [Syncopa: steel beams, a new layout and three new bathrooms](https://www.jarviscontracting.ca/projects/syncopa): North York, Toronto, 2026. Permits, steel beams, layout reworked, stone fireplace out, three new bathrooms, new doors, floors, trim and tile, attic insulation upgraded.
- [Bellamy: opening up a brick bungalow without an addition](https://www.jarviscontracting.ca/projects/bellamy): Scarborough, Toronto, 2025. Whole main floor: load-bearing walls out, steel beams in, new kitchen, mudroom, office, fireplace, floors, trim and doors.
- [Orra: two load-bearing walls out of a childhood home](https://www.jarviscontracting.ca/projects/orra): Ajax, 2025. Two load-bearing walls out, kitchen and living room swapped, gas fireplace with built-ins, new floors, doors and trim, popcorn ceilings removed.

## Design-build or a separate designer and contractor?

With separate firms, the plans are drawn first and priced later, by builders who didn't draw them. With design-build, the people who price the job are the people who draw it and build it. Our [design-build vs general contractor guide](https://www.jarviscontracting.ca/guides/design-build-vs-general-contractor) sets out when each makes sense, and [fixed price vs cost-plus](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus) covers how the contract is priced.

## How does it work here?

You meet James first, and he prices the whole job before design starts. Our designer measures, draws the floor plans, builds a 3D model and presents the finishes in our office, and James's crew builds it. One client put it this way: they "bring the practical and the design together" (Tony O'Brien, Google review).

## Real work

Greenwood took a Toronto house through the permit, interior design and construction in 10 months. At Bellamy, Juliette Interiors designed a modern organic main floor with the owners, and we built it around the steel beams that replaced the walls; both are in [our projects](https://www.jarviscontracting.ca/projects).

## Where we do this

Also in Ajax, Aurora, Brampton, Burlington, Caledon, Clarington, East Gwillimbury, Halton Hills, King, Markham, Milton, Mississauga, Newmarket, Oakville, Oshawa, Pickering, Richmond Hill, Scarborough, Scugog, Toronto, Uxbridge, Vaughan, Whitby, Whitchurch-Stouffville.

5. **Drawings and 3D rendering.** With the plan confirmed, she draws the elevations and the millwork, then puts it all into a 3D rendering, so you see the rooms before anyone orders a cabinet.
6. **Finishes presentation.** We don't take you round the stores: there are too many options. Using what she learned in onboarding, the designer narrows the tile, flooring, quartz, plumbing fixtures and the rest to a few choices that suit your style, collects the samples and presents them to you in our office. If a selection changes the price, the change goes through a change order you sign.
7. **Permits and engineering.** We prepare the permit drawings, bring in the structural engineer wherever a beam or a load changes, and apply to the municipality. If the plan changes after the permit is issued, we file the amendment.
8. **Construction.** Our crew and trades build it, with one point of contact from demolition to the last coat of paint. Our site supervisors write a job log every day, which you can follow in our online app. When we open a wall and find a problem, you hear about it, and what it costs, before we fix it.
9. **Inspections.** The municipal building inspector checks the work at each stage the permit sets, before it gets covered up.
10. **Handover.** We walk the finished house with you and put right anything that isn't. On one job a stair stain didn't match the new floor, so we refinished the stairs.

## Questions

### What is design-build?

Design-build is one firm designing your project and building it, instead of hiring a designer and then tendering the drawings to contractors. The builder is in from the start, so the plans are drawn to the budget instead of priced after they're finished.

### Who designs and who builds at Jarvis Contracting?

At Jarvis Contracting, James's wife runs design through her studio, Juliette Interiors: measurements, floor plans, the 3D model and the finish selections. James runs construction with his crew and trades. They're married, so the design and the build are one conversation.

### How long does a design-build project take?

A design-build project's length depends on its size. Greenwood, a rear extension and a new top floor in Toronto, took 10 months from the permit and the design through construction. West Lynde, a bungalow taken to two storeys, took about four and a half months on site.

### Do I sign one contract or two?

One. Your first estimate from Jarvis Contracting is free. If it works for you, James prices the whole project in a detailed proposal, and you sign the contract, with a 10% deposit, before any design work begins.

# Aurelia: a fast kitchen and bath renovation in old Toronto

A 100-year-old Toronto house renovated in a couple of months before the owners' baby arrived: new kitchen, refinished stair, fireplace and a new bathroom.

- **Town:** Toronto
- **Finished:** 2026
- **Scope:** Kitchen, refinished stair, fluted fireplace, levelled floors, rewiring and a bathroom added mid-job.

Aurelia is a house of about 100 years old in Toronto. The owners had just bought it and were about to have a baby, so the renovation had one fixed date: it had to be done before the baby came home. We designed and built a new kitchen, refinished the stair, put in a fluted fireplace surround, fixed what we found once the house was open and, halfway through, added a bathroom upstairs. The whole job took a couple of months.

## The brief

A young family, a small kitchen footprint and very little time. The kitchen had to hold a lot of storage for a family with a newborn, and the house had to be finished before the baby came. In James's words on site: "We came in here really fast and really efficient."

## What we found

"When you're working in 100-year-old homes, you never know what you're going to find," James says, and this house was no different. Once it was open:

- the floor was out of level across the whole main floor,
- there was water damage throughout,
- and there was knob-and-tube wiring.

All of it was upgraded and built back to our standards before the finishes went in. None of that work shows in the photos.

## The stair

Older Toronto houses often have stairs that were never built to today's rules and are too steep. To update this one without replacing it, we refinished the entire surface of the stair, and dressed the side wall in new picture-frame panelling with black looped balusters on the rail.

## The kitchen

Ceara's challenge was the footprint. A narrow kitchen has to give a young family storage without feeling crowded, so she leaned on drawers: hidden drawers, deep drawers and pull-outs that are easy to reach. The washer and dryer sit in a closet in the kitchen run behind matching doors.

To keep a small room from looking plain, she layered the materials. The cabinet hardware mixes satin brass pulls with honey bronze knobs. Tall cabinets have reeded glass doors. The backsplash and bar wall are a bold veined stone, and the island is a black porcelain slab with a honed leather finish, wrapped down the sides as a waterfall. She also paid close attention to where each material starts and stops, because in a small room every edge is in view.

## The fireplace and the bathroom

In the living room, the fireplace has a fluted surround that runs down to the floor. Upstairs, the owners decided halfway through the job that they wanted the bathroom done too. That left a couple of weeks to design it, choose the finishes, build it and finish it before they moved in. The result has a band of white marble with dark red veining around the tub and lining the niche, glossy white tile above, and black fittings.

## The handover

The job finished in time for the owners to bring their newborn home to a finished house. James told the story on camera on the day of the photo shoot, standing in the finished kitchen.

## Photos

- The bar wall: bold veined stone, brass swing-arm lights and reeded glass doors.
- A brass faucet and a linear chandelier over the black island.
- Satin brass pulls run the length of the white cabinets.
- The laundry hides in a closet in the kitchen run.
- The dining room opens through to the living room and fireplace.
- The steep original stair, refinished, with a new panelled side wall.
- Picture-frame panelling dresses the side of the stair.
- The new fluted fireplace surround.
- Detail of the fluting where the surround meets the floor.
- The upstairs bathroom, added halfway through the job.
- A band of bold red-veined marble wraps the tub.
- The niche is lined in the same marble as the band.

# Greenwood: a new top storey and rear extension in Toronto

A narrow east-end Toronto house rebuilt with a new top storey, a rear extension and a bigger basement, taken from permit to handover in 10 months.

- **Town:** Toronto
- **Finished:** 2026
- **Duration:** 10 months
- **Scope:** Top floor replaced with a new storey, rear extension, basement enlarged, full interior design and build.

Greenwood is a narrow brick house in Toronto's east end. We took off the top floor and built a new storey in its place, pushed the back of the house out, enlarged the basement and designed every room inside. It took 10 months from the permit application to handover, and the whole time the design and the build were run by the same two people: James on site and Ceara at Juliette Interiors.

## The brief

The owners are a family of four in a house with a compact footprint. They needed more room, a primary suite of their own and a main floor that worked as one space. We took the job through the permit process, the interior design phase and construction, with a lot of back and forth between builder, designer and architect along the way.

## The design problem

A narrow house leaves little room for a kitchen island, a proper dining table and storage on the same floor. Ceara's answer was to plan everything around flow. The kitchen, the island and the open stair share one run of herringbone floor, so the main floor reads as one long room. The island has a rounded end and an overhang for stools instead of a separate eating counter. The dining area is a built-in banquette with glass-front cabinets on each side. Small appliances hide behind pocket doors in a walnut-lined cabinet.

Upstairs, the clients wanted a floor that was theirs alone. The new top storey holds the primary bedroom, an ensuite that opens into a wet room under a skylight, and a den with a walkout balcony. James put it plainly on camera: "This entire floor that we're standing on didn't exist before."

## How we built it

The side of the house is a double brick wall, and taking the roof off first could have left it standing on its own. So we kept the roof on, took out the floor sections one at a time and rebuilt each one, and only lifted the roof once the new floors were in. That kept the wall braced the whole way through.

The new top floor had to sit at a set height, which is why the roof lines slope down into the bedroom. The back of the house came off at the same stage, and the rear extension was framed alongside the new floors.

## What we found, and what changed

Two things came up once the house was open.

First, the house had no waterproofing and no weeping tile at the footing, so nothing moved water away from the foundation, and the lot left little room to dig. Our answer was a bridged weeping system: it collects the water at the footing and carries it to a sump pump, which pumps it away from the house. It fit the tight space and gave an old foundation the drainage it never had.

Second, with the plans and the demolition in front of us, it made sense to take out a brick wall in the basement and gain floor area. That meant new engineering and an amendment to the permit, and it cost a short delay. James's view: a bigger basement adds value to the house and isn't much more expensive to build while everything is already open.

## The finishes

The floor is a luxury vinyl herringbone, chosen by Ceara, who picks every finish on our jobs. As James says in the design details video, it's cost effective and durable, but it expands and contracts, so every transition to another floor is a solid wood overlap piece stained to match. The fireplace wall is lime-washed and set on mitred Taj Mahal stone, with custom doors for the TV area. By the front door, a compact foyer gets an arched opening, a pocket door and a powder room with a curved vanity finished in micro-cement. Ceara also furnished the house and fitted motorised blinds.

# Solace: a home gutted to the studs and rebuilt inside

A home gutted to the studs: load-bearing walls removed and reframed, the whole space spray-foamed, a new washroom upstairs and a soft pink and cream interior.

- **Town:** Toronto
- **Finished:** 2026
- **Duration:** 3 months
- **Scope:** Complete gut to the studs, load-bearing walls removed and reframed, spray foam throughout, new upstairs washroom, full interior design.

Solace is a home we took right back to the studs. We removed load-bearing walls and reframed the structure, spray-foamed the entire space and built a new washroom upstairs. Ceara at Juliette Interiors designed the interior and chose every finish, in cream, pale oak and pink-veined stone. The photos were taken in May 2026.

## What we built

This was a complete gut. Every wall was opened down to the framing, which let us change the structure, not just the surfaces. Load-bearing walls came out, and we reframed.

With the framing bare, we spray-foamed the whole space. Insulation is easiest to do well when nothing is in the way, and on a gut job every wall, ceiling and cavity is open at once. Upstairs, we added a new washroom.

## The design

Ceara's design repeats one idea: curves. The fireplace wall bows out in plaster, the island has a rounded end, the cabinet wall by the fridge rounds off at the corner, and arched openings lead to the stair and the dining room. The mirrors in the bathrooms are ovals in brass. A herringbone floor runs through the kitchen, the living room and the dining room.

## The kitchen

The island is fluted pale oak with a rounded end and a top in pink, grey and cream veined stone. The same stone runs up the wall behind the counter as the backsplash. The sink is in the island, facing white wall ovens and cream slab cabinets, and the fridge sits in a cabinet wall with a rounded corner beside an arched doorway. Behind the island, an oak-lined cabinet holds the coffee machine.

## The living and dining rooms

The fireplace wall is the centre of the living room. A linear fireplace and a TV sit in a curved plaster face, over a long low cabinet that runs the full width of the wall. On each side, a picture-frame panel holds a round sconce. Next to it, an arched opening leads to an oak stair.

The dining room is through a wide arch, with blush shell pendants over the table and another arched doorway at the far side.

## The bathrooms

One bathroom has a vessel sink on an oak vanity, an oval brass mirror and a tub behind a curved glass screen, tiled in thin vertical tile with glass corner shelves. In another, wood panelling wraps the vanity wall and carries on across the ceiling, with an oval brass mirror, two globe sconces and brushed gold taps, in a room with pink walls. Elsewhere, a dressing table is built into a wall of oak wardrobes.

# Syncopa: steel beams, a new layout and three new bathrooms

Steel beams, a reworked layout, a stone fireplace taken out and three new bathrooms, with new doors, floors, trim and tile and upgraded attic insulation.

- **Town:** North York, Toronto
- **Finished:** 2026
- **Duration:** 4 months
- **Scope:** Permits, steel beams, layout reworked, stone fireplace out, three new bathrooms, new doors, floors, trim and tile, attic insulation upgraded.

Syncopa is a house we reworked from the inside. We took it through permits, put in steel beams, changed the layout, took out a stone fireplace and built three new bathrooms. The doors, floors, trim and tile are all new, and the attic insulation was upgraded. James ran the build. Ceara at Juliette Interiors chose the finishes, as she does on all our jobs.

There's no video walkthrough of this job on the site yet, so everything below comes from James's list of the work and from the finished photos.

## The scope

In James's words, Syncopa was:

- permits,
- steel beams,
- the entire layout reworked,
- the stone fireplace taken out,
- three new bathrooms,
- all new doors, floors, trim and tile,
- upgraded attic insulation.

## The structure

When a layout changes this much, walls that carry weight often have to move or come out, and steel beams take over the load they used to carry. Work like that needs a building permit, and Syncopa had both: permits and steel beams.

The stone fireplace came out as well. None of the finished rooms in the photos has one now. What they do show is how the rooms connect: a long oak island in the middle of the kitchen, and wide cased arches between the rooms. James points out in the walkthrough video where a load-bearing wall came out to open the kitchen, and the new hall runs under an arched barrel ceiling, with a mudroom and a powder room added off to the side.

## The kitchen

Every finish here was Ceara's choice. The kitchen is cream shaker cabinets with crown moulding run to the ceiling, an oak island with a white veined top, and glossy taupe square tile in a handmade look. The tile goes all the way up behind the range, under a tapered cream hood. Three white fluted glass pendants hang over the island, and two brass swing-arm sconces light the sink under the window.

Storage is built into the walls. A tall cabinet opens to an oak-lined coffee station, and its doors slide back out of the way. Next to it, an arched niche has oak shelves over the counter, with a lift-up door that hides a small cubby. The top drawers and some lower panels have reeded fronts.

## The bathrooms

Three bathrooms are new. The photos show:

- a bathroom with a long oak double vanity, tall oak linen cabinets at each end, arched black mirrors, polished nickel taps and glossy white vertical tile,
- a second bathroom with an oak shaker vanity, a shield-shaped mirror between two oval brass sconces and a glass shower,
- a powder room painted a deep plum, with a black vanity, a marble-look top and polished nickel lever taps.

In the shower, white stick tile runs above a band of large grey veined tile, with a niche and polished nickel fittings.

## The rest of the house

The new floor is a wide plank in a warm brown, and it runs through the kitchen and the dining room. The dining room sits through a wide arch, with a wood-panelled ceiling inset in the trim. Elsewhere, a built-in wall unit has oak-lined open shelves on each side of a recess, over a long run of cream cabinets with vertical-grooved doors.

If you're planning to rework the layout of your own house in Durham Region, Ontario, or Toronto, the [whole-home renovations](https://www.jarviscontracting.ca/whole-home-renovations) page explains how we take one on.

## Watch it

James walks the finished main floor in the [Syncopa walkthrough](https://www.jarviscontracting.ca/videos/syncopa-walkthrough): the barrel-vaulted hall, the new arches, the kitchen with its appliance garage, and where the load-bearing wall used to be.

## Photos

- The range wall: a tapered hood with a crown, and handmade-look tile up to the ceiling.
- The sink wall, with brass sconces over the window and reeded fronts on the top drawers.
- Three pendants hang over the island and its three stools.
- A wide arch opens into the kitchen.
- The coffee cabinet is lined in oak, and its doors slide back out of the way.
- Under the arched shelves, a lift-up door hides a cubby on the counter.
- Through the arch, the dining room has a wood-panelled ceiling inset in the trim.
- A built-in wall unit: oak-lined shelves either side of a recess, over a long run of cabinets.
- A bathroom with an oak double vanity and tall linen cabinets at each end.
- Polished nickel fittings, white stick tile and a band of large grey tile in a shower.
- A second bathroom: an oak vanity, a shield-shaped mirror and a glass shower.
- The powder room is painted a deep plum, with a black vanity.

# Bellamy: opening up a brick bungalow without an addition

A brick bungalow in Scarborough opened up with steel beams instead of an addition: new kitchen, mudroom, office and fireplace, finished on the promised date.

- **Town:** Scarborough, Toronto
- **Finished:** 2025
- **Scope:** Whole main floor: load-bearing walls out, steel beams in, new kitchen, mudroom, office, fireplace, floors, trim and doors.

Bellamy is a brick bungalow in Scarborough where the owners wanted a bigger house without building an addition. We took out the load-bearing walls on the main floor and put in steel beams and point loads to carry the structure. Then we rebuilt the whole floor around the open space: a new kitchen, a mudroom, a bigger office, a stone fireplace with arched built-ins, and new floors, trim and doors. We found asbestos and fire hazards along the way and still handed the house back on the day we said we would.

## The brief

"These clients came to me and they really wanted a bigger house but they didn't want to add an addition," James says. With the footprint fixed, the only way to get more space was to take out what was blocking the view across the floor. When you walked in the front door there was a small corridor, a large wall running down the floor and a narrow door opening into the next room. The owners also needed an office, and that had to survive the change.

## The structure

Taking out load-bearing walls is the biggest risk on a job like this, and it was the main challenge from the start. The walls came out, and steel beams and point loads went in to pick up what they used to carry. One of those point loads came down in the basement. That was one more problem to solve before the main floor could be finished. The result is one open room from the front door to the back of the kitchen.

## What we found

The house had asbestos. "We got the right people to come in and remove it safely," James says. It also had fire hazards, which we fixed. Everything has been inspected since. Neither problem moved the finish date: "We delivered the final product on the date that we said we would."

## The design

Ceara at Juliette Interiors worked with the owners on a modern organic design: natural stone, oak and modern textures. The owners liked the natural elements, so the fireplace is stacked natural stone with an oak mantel, set between two arched built-ins with fluted white doors and oak shelves. A conduit runs from the cable box to the TV so no wires show.

The kitchen is custom throughout.

The island has pale oak sides and a dark top. The hood is curved at the corners, which the owners loved, and it ties in with the curve of the farmhouse sink. Dark appliances keep it modern. In the coffee niche, the shelf is lit from underneath and has a thin brass rail along the front so cups can't slide off. Details like that give the kitchen the personal, custom look the owners asked for.

## The rest of the floor

At the front door there is now an open mudroom: a sage-green wall of cabinets with coat hooks, a bench, clothing storage and shoe storage. The office got bigger by taking a tub out of the bathroom next to it. That room became a powder room, and the office gained space for a desk, with cabinets painted to match. Ductwork that had to go somewhere was hidden in a linen closet, with shelving added for storage.

## Watch it

The [final-day walkthrough](https://www.jarviscontracting.ca/videos/bellamy-final-day) shows the finished floor room by room, and [Bellamy on schedule](https://www.jarviscontracting.ca/videos/bellamy-on-schedule) is James on the problems and the finish date.

# Orra: two load-bearing walls out of a childhood home

Two load-bearing walls came out of a brick home in Ajax so the kitchen and living room could swap places, with every duct and pipe hidden and no bulkheads.

- **Town:** Ajax
- **Finished:** 2025
- **Scope:** Two load-bearing walls out, kitchen and living room swapped, gas fireplace with built-ins, new floors, doors and trim, popcorn ceilings removed.

Orra is a two-storey brick home in Ajax with a curved stair under a round foyer. It is also the house our client grew up in. We took out two load-bearing walls, swapped the kitchen and the living room, put in a gas fireplace with built-ins, and redid the floors, doors and trim through the house. Every duct and pipe that was in those walls is now hidden, with no bulkheads anywhere on the open floor.

## The brief

"This is our client's childhood home, so there's a sentimental aspect to this project," James said on demolition day. The client wanted a modern contemporary house, and that meant opening up the back half of the main floor. The old main floor was closed in by walls, with the kitchen and living room each where the other is now.

The plan from day one:

- remove two load-bearing walls and put steel beams in their place,
- move the kitchen to where the living room was, and the living room to where the kitchen was,
- take out the old fireplace and put the range, a hood and a large island in its place,
- take out a window and brick it in so the new cabinets could run to the end of the wall,
- install a gas fireplace with built-ins on each side,
- replace the floors, doors and trim, repaint and remove the popcorn ceilings.

## The structural day

The steel beams sit where the load-bearing walls stood, picking up the floor joists of the storey above from both sides. To take the walls out safely, we built temporary walls on either side to carry the load of the second floor, lifted the beams into place, and only then took the temporary supports out. By the end of that day the back half of the house was one open room.

## The hidden problem

When the drywall came off the load-bearing wall, it was full: ductwork, plumbing and electrical, all of which needed a new route. The easy fix is a bulkhead, a boxed-in lump across the ceiling. We didn't want one. Instead we built a false wall in front of the existing wall, ran the ductwork up through the ceiling and down behind the new kitchen, and hid the plumbing behind the kitchen too. "We have no bulkheads anywhere in this entire space," James says.

## The stair

Problems come up on any job this size, and one came up on the stairs. The owner had approved the stain, and we finished the stairs. Once the new floor went down beside them, the colours didn't match, and neither James nor the owner was happy with it. So we refinished the stairs to match the floor. In James's words: "I'm going to stand by my work and I'm going to rectify this situation." The [stair video](https://www.jarviscontracting.ca/videos/orra-stair-refinish) shows the mismatch and the fix.

## The finish

The foyer has a chevron white oak floor that runs into the main floor, and the curved stair now matches it. In the kitchen, a fluted oak hood sits over the range where the fireplace used to be, with a white oak island in the middle. The new gas fireplace is faced in white veined stone with built-ins on both sides. With the walls gone, light from the windows reaches right across the floor.

James's advice from this job applies to most renovations: do it all at once. "When you do everything at once, it's faster, it's cleaner," he says, and it costs less than doing the same work in pieces.

# West Lynde: a Whitby bungalow made two storeys in 4.5 months

A one-storey Whitby house turned two-storey: about 800 sq ft added upstairs, a new kitchen and two new bathrooms, built from mid-May to late September 2023.

- **Town:** Whitby
- **Finished:** 2023
- **Duration:** 4.5 months
- **Scope:** New second storey of about 800 sq ft with two bedrooms, a walk-in closet and a bathroom; new kitchen, two new bathrooms, floors, stairs and trim below.

West Lynde started as a one-storey house in Whitby and is now a two-storey one. We built a full second storey of about 800 square feet on top, then redid the house underneath it: a new kitchen, two new bathrooms, new floors, new stairs and new trim. We started in mid-May 2023 and were cleaning up for handover in the last week of September, about four and a half months for the whole build.

## The brief

This counts as an addition: the house went from one storey to two. Upstairs we built two bedrooms of exactly the same size, a full walk-in closet and a bathroom with a pocket door to save floor space. Downstairs, we updated everything in the existing house.

People often expect a job this size to take a year or more. This one took under five months, including the kitchen, both bathrooms, the floors and the trim. It is the same advice James gives on every job: do the work all at once, because it's faster and cleaner.

## The roof problem

The drawings showed the new roof tying into the old one in a way that would have caused trouble. The new rafters would have come down into the existing house and left low spots where water could sit. We didn't want to build it that way. Our solution was to cut out as many slopes as we could and build one single sloped roof. One slope means nowhere for water to pool and no ice damming in winter.

## The kitchen

Ceara at Juliette Interiors chose a modern organic look for the kitchen. The island and the range hood are both painted Evergreen Fog, a soft green that adds warmth while staying timeless. The cabinets are White Dove, the countertop is Picasso grey quartz, and the quartz carries on up the wall as a full-height backsplash for a European look. The cabinets mix handles and knobs, which keeps the kitchen from looking like builder grade.

## The bathrooms

The primary ensuite uses warmer finishes: gold, neutral beiges and a pop of colour in glossy emerald tile. A gold edge trims the tile and the niche, the faucets are gold, and the floor is a marble hexagon with gold and grey tones in it. The green tile edge took a conversation on site between James, the tiler and Ceara, because the tile size would have left a thin sliver at one end, and nobody wanted an uneven line.

## The doors and trim

In a hallway with several doors close together, James set every door top level with a laser so they all line up. The frames, jambs and casings come from his supplier as ready-made sets. That saves the homeowner labour, saves the crew time and gives a square frame every time.

## How it ran

How a job like this one runs today, from the first visit to the finishes presentation in our office, is on [our process page](https://www.jarviscontracting.ca/process).

# Stone Ridge: a finished basement in Scarborough

A Scarborough basement finished as a rec room with a panelled media wall, an arched wet bar, a full bathroom, a laundry room and a new bedroom.

- **Town:** Scarborough, Toronto
- **Scope:** Full basement finish: rec room, media wall, arched wet bar, bathroom, laundry room and bedroom.

Stone Ridge is a basement in Scarborough, in the east of Toronto. We finished it from front to back: a rec room with a media wall, an arched wet bar, a full bathroom, a laundry room and a bedroom. Ceara at Juliette Interiors designed it and our crew built it. We don't have a video from this job, so everything below comes from the finished rooms and what you can see in the photos.

## What we built

The basement was a set of closed-off spaces, and we opened it into one floor. It now holds a rec room for the TV, a wet bar with a curved kitchenette, a full bathroom, a laundry room and a bedroom reached through a walk-in closet with pocket doors. Every room has something built in. The same brass, white oak and cream finishes run through all of them, so the basement looks like the rest of the house rather than an add-on.

## The design problem

Basements are low, and their small windows sit high in the wall. A big open room down there can feel like a basement however it's finished. Here the design puts the character into the walls: panelling, an arch and built-ins, rather than furniture.

The media wall is the anchor of the rec room. Vertical panelling runs floor to ceiling behind the TV, with white oak floating shelves and brass sconces on each side and a long low cabinet under a stone top. It gives the room a focal point, with a small window set high in the corner beside it.

The wet bar sits in its own arch. The inside of the arch is panelled and painted a dark brown, so the bar reads as a built-in nook rather than a run of cabinets against a wall. It has a sink, a built-in microwave, cream lower cabinets and one shelf under two round brass-rimmed lights.

## The bathroom

The bathroom is the most detailed room on the floor. It has a white oak shaker vanity, an arched black mirror and a frameless glass walk-in shower in handmade-look tile. The shower niche and bench are faced in a white stone with heavy dark red and black veining, and the floor is a black and white octagon-and-dot tile. Black clamps and a black handle on the shower glass pick up the mirror frame, and brass taps and sconces tie it back to the bar and the rec room.

## The laundry and the bedroom

The laundry room is built to be worked in. It has a deep sink with a brass faucet, a pull-out folding shelf, closed storage and a rail under the window for hanging clothes. The bedroom has a white oak nightstand under a frosted window, with a wall-mounted light above it.

## What this job proves

Stone Ridge shows the kind of basement we build: every room planned, built-ins doing the work that furniture would otherwise have to, and one set of finishes carried through the whole floor so it feels like part of the house. If you're planning a basement in Toronto or Durham Region, Ontario, the [basement renovations](https://www.jarviscontracting.ca/basement-renovations) page explains how we take one on.

## Watch it

James and Ceara walk through the finished basement in the [Stone Ridge tour](https://www.jarviscontracting.ca/videos/stone-ridge-tour), from the open rec room to the curbless shower in the ensuite. The [styled walkthrough](https://www.jarviscontracting.ca/videos/stone-ridge-styling) is a short, music-only look at the details.

## Photos

# Design-build or architect plus contractor in Ontario?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

Design-build puts the design and the construction of your addition under one contract with one firm. The architect-plus-general-contractor route splits them into two contracts, and a builder prices the drawings once they're done. Neither model has a credible published saving. As of October 2026 both run under the same Ontario rules. A renovation contract over $50 must be in writing. The final price can't run more than 10% over the estimate unless you agree to new work or a new price ([Ontario, your rights when starting home renovations](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

## Key takeaways

- Ontario requires any home renovation contract worth more than $50 to be in writing as of October 2026, so both models end in a signed document that spells out the work and the price ([Ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Ontario recommends at least 3 written estimates, which is easier when every builder prices the same drawings, a real point for the architect-plus-contractor route ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Our permit drawings for an addition are $6,000 to $12,000 before HST, a cost you pay in either model, separately or inside one contract. That's drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra.
- In Whitby, starting work before a permit application costs the greater of $100 or 25% of the application fee, so settle who files before anything comes down ([Town of Whitby, Schedule N, 2026](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)).
- You must hold back 10% of the value of work supplied until liens expire, and that applies to design-build and two-contract jobs alike ([Construction Act s. 22(1)](https://www.ontario.ca/laws/statute/90c30)).

## What's the difference between design-build and an architect plus a general contractor?

The difference is how many contracts you sign and when the price gets fixed. With design-build, one firm designs, prices and builds. The people drawing the plans talk to the people who'll frame the walls while the design is still moving, so the budget gets checked as you go.

With the two-contract route, you hire an architect or designer first. They take you from sketches to permit drawings, and often to a full set of tender documents. You then send those drawings to several general contractors, compare bids and sign a construction contract with one of them. If you pay for it, the architect can stay on through construction to review the work.

Ontario tells you to "Always get at least 3 written estimates" ([Ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). That's easier when every builder is pricing the same drawings, which is a real point in favour of the two-contract route. With design-build you compare firms earlier, on their process, their past work and a budget range, before the drawings exist.

## Who carries which risk in each model?

Risk follows responsibility, and the two models split responsibility differently. Here's how the main risks usually fall on an addition or renovation:

| Risk | Design-build | Architect plus general contractor |
|---|---|---|
| Contracts you sign | One, covering design and construction | Two: one with the designer, one with the builder |
| A gap or error in the drawings | The firm that drew it builds it, so it can't blame the drawings | Designer and builder can each point at the other, and you sit between them |
| Bids come in over budget | Cost is checked while the design develops | Bids arrive after drawings are finished; redesign costs you more fees and time |
| Independent check on the builder | None unless you hire one | The architect can review work and invoices if that's in their contract |
| Competitive pricing | You compare firms early, on a budget range | Several bids on identical drawings |
| Building permit application | Usually filed by the firm as your agent | Usually filed by the designer or builder as your agent, or by you |

Note: This table shows how the models usually divide responsibility; your contracts set the actual split, so read them line by line.

The forum evidence lines up with that table. A lot buyer weighing a design-build firm against a separate architect on Houzz said the appeal was a builder who "will be committed to our budget from the start" ([Houzz discussion](https://www.houzz.com/discussions/5799944/new-construction-architect-vs-design-build-firm)). On RedFlagDeals, homeowners comparing the two routes worry about the opposite risk: one firm marking its own homework, with nobody independent watching ([RedFlagDeals thread, 2015](https://forums.redflagdeals.com/architect-vs-design-build-contractor-1663695/)). Both worries are fair.

## Does design-build cost less than an architect and a general contractor?

There's no credible answer in percentage terms. We couldn't find a published Ontario study comparing the two models on real jobs, and architect fee percentages online come from forum replies and a price-guide snippet we couldn't open. We won't print them as fact.

The same things drive cost in both models. Size and structure come first: a steel beam, underpinning, a new top storey on old walls. Then the finishes, what you find when the walls open, and how many changes you make after the price is set. Our own 2026 range for additions is $350 to $600 per sq ft, and $180,000 to $450,000 for a single-storey rear addition of 300 to 700 sq ft, before HST. That's a range, not a quote: your price comes after James sees the house, and the first estimate is free. Our [home addition cost guide](https://www.jarviscontracting.ca/guides/home-addition-cost-ontario) goes through the ranges in detail.

Where the models differ is when you learn the number. In design-build, the price firms up as the drawings do. In the two-contract route, you pay for full drawings before any builder prices them. If the bids come in high, you pay the designer again to cut the scope.

## Who applies for the building permit in each model?

You do, legally, though someone usually files for you. Ontario puts it plainly: "It's your responsibility to get building permits" ([Ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). The Building Code lets the owner or an authorized agent make the application, and the review clock only starts on a complete one (Div. C 1.3.1.3.(5), [2024 Building Code Compendium](https://www.publications.gov.on.ca/301880)).

In Whitby, in Durham Region, Ontario, applications go through the Town's E-Portal at portal.whitby.ca ([Town of Whitby, building permits](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)). In design-build, the firm normally files as your agent and answers the examiner's comments. In the two-contract route, the designer often files, because the comments are about their drawings. Either way, the contract should name who files, who pays the fee and who answers the comments.

The design also decides whether you need a minor variance, whoever draws it. Here's what a residential minor variance costs across Durham Region in 2026:

| Town | Minor variance fee | Source |
|---|---|---|
| Whitby | $1,526 (plus $930 for the Central Lake Ontario Conservation Authority on land it regulates) | [Town of Whitby application](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) |

## When is an architect plus a general contractor the better choice?

It's the better choice when you want an independent professional on your side. If you'd sleep better with someone who doesn't work for the builder checking the work and the invoices, hire an architect for construction review as well as design.

It also suits you if you already have drawings you like, if you want several bids on identical plans, or if the house needs a specialist designer you've already chosen, say in Whitby's Werden's Plan or Brooklin heritage districts. Design-build suits you better when you want one firm answerable for both the drawings and the build, a budget checked while the design is still cheap to change, and no handoff between two offices.

## What should the contract say in either model?

The same Ontario basics apply to both. The province says a renovation contract should list the contractor's details, a thorough description of the work, warranties, total cost and payment terms, start and finish dates, the payment schedule and deposit, cleanup and the sub-trades. It recommends a deposit of no more than 10% ([Ontario.ca](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

The Construction Act adds the 10% holdback ([s. 22(1)](https://www.ontario.ca/laws/statute/90c30)). It covers design as well as building: section 14(3) confirms that an architect's services can give rise to a lien. A contractor's lien expires 60 days after the earlier of publication of substantial performance or the contract being completed, abandoned or terminated ([s. 31(2)](https://www.ontario.ca/laws/statute/90c30)). How the price itself is set is a separate choice, covered in [fixed price vs cost-plus](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus). The checks to run before you sign are in [questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor).

One thing neither model gives you on a renovation is a Tarion warranty. The Home Construction Regulatory Authority (HCRA) says renovators "aren't licensed or regulated like new home builders" ([HCRA page on finding a renovator](https://www.hcraontario.ca/resources/finding-a-renovator/)); our [HCRA and Tarion guide](https://www.jarviscontracting.ca/guides/hcra-and-tarion-explained) explains where that line sits.

## How we work

We're design-build, and our contracts are fixed price. Ceara Jarvis leads design through her studio, Juliette Interiors, we draw the permit drawings in-house, and James Jarvis runs construction, all under one contract. The whole project is priced and the contract signed, with a 10% deposit, before design begins, and any change to the price goes through a change order you sign. The steps are on our [design-build](https://www.jarviscontracting.ca/design-build) and [process](https://www.jarviscontracting.ca/process) pages.

The nearest finished job with a full write-up is [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), in east Toronto, roughly 30 km west of our Ajax office. It was a rear extension plus a new top storey with a primary suite, a wet room with a skylight and a den with a walkout balcony. We also enlarged the basement by removing a brick wall and did the full interior design. It took 10 months including design, permits and construction. If you'd rather have an independent architect watching the builder, the two-contract route above is the fair comparison to make.

## Questions

### Is design-build cheaper than hiring an architect and a general contractor in Ontario?

There's no credible published figure showing design-build is cheaper or dearer than an architect plus a general contractor in Ontario. The cost of an addition depends on its size, structure, finishes and what's found inside the walls, and those don't change with the hiring model.

What changes is when you learn the price. Design-build checks cost while the design develops; the two-contract route prices finished drawings, which can mean paying for redesign if bids come in high.

### Who is responsible for mistakes in the drawings with design-build?

With design-build, the firm that drew the plans also builds them, so a gap in the drawings is its problem to fix under the one contract. With an architect plus a general contractor, responsibility depends on two separate contracts, and the designer and builder can each point at the other.

Read the contract either way. It should say who fixes drawing errors and who pays for them.

### Can I still get competing prices if I choose design-build?

Yes, but you compare design-build firms earlier, on their process, past work and a budget range, before final drawings exist. Ontario recommends at least 3 written estimates, and the two-contract route makes that easier because every builder prices identical drawings.

If competitive bids on the same plans matter most to you, an architect plus a general contractor is the better fit.

### Who gets the building permit for an addition in Whitby?

The homeowner is responsible for building permits in Ontario as of October 2026, but the Building Code lets an authorized agent file the application. In Whitby, applications go through the Town's E-Portal, and a design-build firm or your designer usually files as your agent.

Starting work in Whitby before applying costs the greater of $100 or 25% of the application fee under the Town's 2026 fee schedule, so agree in writing who files before demolition starts.

### Does the 10% holdback apply to a design-build contract?

Yes. Section 22(1) of Ontario's Construction Act requires every payer under a contract where a lien may arise to hold back 10% of the value of services or materials supplied, and design is a service to the improvement. Section 14(3) confirms architects' services can give rise to a lien.

So if you sign one design-build contract, or two separate ones, keep 10% back until the lien period has passed.

### Does a design-build firm need an HCRA licence to renovate my house?

A design-build firm typically doesn't need an HCRA licence for renovation work on an existing house. The Home Construction Regulatory Authority (HCRA) licenses new home builders and sellers, and it says renovators aren't licensed or regulated the way builders of new homes are. Coach, laneway and tiny homes generally do need licensing and warranty coverage.

That means a renovation or addition carries no Tarion warranty, whichever model you choose, so the warranty terms in your contract matter.

# Do you need a permit to finish a basement in Durham Region?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

Yes. Ontario's [Building Code Act](https://www.ontario.ca/laws/statute/92b23) requires a building permit to finish a basement in every town in Durham Region, Ontario. The Code's only small-project exemption is for sheds. As of October 2026, the permit fee for a 700 sq ft basement works out to about $356 in Clarington and up to $693 in Whitby on each town's 2026 schedule, and Pickering adds a $1,000 refundable deposit.

## Key takeaways

- A permit is required to construct under section 8 of the [Building Code Act](https://www.ontario.ca/laws/statute/92b23), and the Code exempts only sheds up to 15 m2 with no plumbing (Div. C 1.3.1.1.(6), [2024 Building Code](https://www.publications.gov.on.ca/301880)).
- Oshawa prints its own basement line, $7.79 per m2 charged on at least 50 m2, per its [2026 fee by-law](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).
- Pickering charges $7.37 per m2 for finished basements plus a $1,000 refundable performance deposit, effective 6 January 2026, per its [2026 user fees](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING).
- Starting before you apply costs the greater of $100 or 25% of the fee in Whitby, per [Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf), and 50% extra in Oshawa and Clarington.
- The Code gives the town 10 business days to decide a complete permit for a single-unit house, and likely 15 for a house with a basement apartment ([2024 Building Code](https://www.publications.gov.on.ca/301880)).

## Do you need a permit to finish a basement in Durham Region?

You do, in Whitby, Oshawa, Ajax, Pickering and Clarington alike. Section 8 of the [Building Code Act](https://www.ontario.ca/laws/statute/92b23) says no one may construct without a permit, and the [2024 Building Code](https://www.publications.gov.on.ca/301880) doesn't exempt basement finishing, interior alterations, decks or garages. Its one homeowner-sized exemption is a one-storey storage shed of up to 15 m2 with no plumbing (Div. C 1.3.1.1.(6)).

In practice, framing walls, adding a bathroom, moving plumbing, removing or adding a wall, or adding a bedroom all fall inside "construct". So does cutting a new entrance or enlarging a window. Electrical work is separate: a Licensed Electrical Contractor files a notification with the [Electrical Safety Authority](https://esasafe.com/compliance/finding-the-right-contractor/) before starting, and that's in addition to the building permit.

If the basement will become a separate unit, the permit is needed even if you build almost nothing. Section 10 of the Building Code Act covers a change of use that increases the hazard, and the Code lists converting one dwelling unit into more than one as exactly that (Div. C 1.3.1.4.(1)(b)). The Code rules for a second unit are in our [requirements guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario).

## What does a basement permit cost in each Durham town?

Only two of the five lakeshore towns name basements in their fee schedules, so for the other three you have to infer which line applies. As of October 2026, here's the floor-area rate each town's 2026 schedule supports and what it works out to on a 700 sq ft (65.0 m2) basement:

| Town | Basement line printed? | Rate used | 700 sq ft basement (calculated) | Minimum fee | Source |
|---|---|---|---|---|---|
| Whitby | No | $10.65/m2 interior alteration (BGP-11), likely but not confirmed | $693 | $305 | [Whitby Schedule N, 2026](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) |
| Oshawa | Yes, "Finishing Basement (Existing or New House)" | $7.79/m2, charged on the greater of actual area or 50 m2 | $507 | $160 | [Oshawa fee by-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) |
| Ajax | No | $7.16 interior alteration (B5), likely but not confirmed | $466 | $146 | [Ajax Schedule A, 2026](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf) |
| Pickering | Yes, within "Interior Partitioning and Finishing" | $7.37/m2 GFA, plus $1,000 refundable deposit | $479 plus deposit | $180 | [Pickering 2026 user fees](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING) |
| Clarington | No named line | $5.48/m2 interior alteration, likely but not printed for basements | $356 | $135.31 | [Clarington fee by-law 2024-006](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington) |

Note: these are our area-times-rate calculations, not quotes from the towns; the building department sets the final fee, and Oshawa's and Clarington's by-laws provide for 3% increases each 1 January.

Be careful with Whitby, Ajax and Clarington. Whitby's Schedule N has no separate basement line, so the $10.65 interior alteration rate is the likely fit, but the schedule doesn't say so. Ajax's schedule has no explicit basement line either, and the schedule doesn't print the unit beside every rate, though per m2 is the likely reading. Clarington's by-law has an interior alteration rate but no line that names basements. Call the building division and ask which line they'll use before you budget on our number.

Pickering's line is the clearest: its "Interior Partitioning and Finishing" rate names apartments in houses and finished basements. Oshawa's 50 m2 floor means a small basement still pays at least $390 (our calculation: 50 m2 at $7.79).

## What changes if the basement becomes an apartment?

The fee line changes, and most towns add a flat charge for a new entrance below grade. As of October 2026, here's what the same five schedules charge when the basement is a second unit:

| Town | Second-unit rate | 700 sq ft unit (calculated) | Below-grade entrance |
|---|---|---|---|
| Whitby | $10.65/m2, "Residential (ADU) Alterations" (BGP-10) | $693 | $305 flat, "Below Grade Entrance/Underpinning" |
| Oshawa | No specific line; staff calculate it (portal type "Add a dwelling unit") | Not printed | $160 flat for a walk-up stair |
| Ajax | $9.68, "Residential Accessory Dwelling Unit" (B3) | $630 | $329 (B10) |
| Pickering | $7.37/m2, plus $1,000 refundable deposit | $479 plus deposit | $180 for a basement walkout |
| Clarington | $6.68/m2, "Apartment In-House" | $434 | Not found in the schedule |

Note: these figures cover the building permit only; registration, a minor variance or a curb cut are separate charges where they apply.

Ajax also lists a $146 flat fee for a "retrofit accessory apartment" (B4) on the same [schedule](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf); ask the Town whether your project fits it. In Whitby, the Housing Accelerator Fund incentive reimburses the ADU permit fee and the below-grade entrance fee for complete applications made by 31 December 2026. Our [Whitby ADU incentive guide](https://www.jarviscontracting.ca/guides/whitby-adu-incentive) has the dates, and the [cost guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) puts these fees next to the build cost.

## What happens if you start without a permit?

You pay a surcharge on top of the fee, and you may have to open finished walls so an inspector can see the framing, insulation and plumbing behind them. The surcharge is the smaller cost. As of October 2026:

- **Whitby:** work started before a permit application costs the greater of $100 or 25% of the application fee, per [Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf). On a $693 basement permit that's $173 more (our calculation).
- **Oshawa:** 25% extra if work began after you applied but before the permit, and 50% if you never applied, per its [fee by-law](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf). On a $507 basement permit, 50% is about $254.
- **Clarington:** the same 25% and 50% surcharges, per [By-law 2024-006](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington).
- **Ajax and Pickering:** our research didn't confirm a surcharge rate for either. Ask the building department rather than assume there isn't one.

The bigger risk is the drywall. A basement finished without a permit can't show its framing, vapour barrier or drain lines to an inspector, so legalising it later usually means cutting the finish open. For scale, we price legalising an already finished basement at $45,000 to $95,000 before HST in 2026.

## What is Pickering's $1,000 basement deposit?

It's a refundable performance deposit the City added on 6 January 2026 for finished basements, secondary suites and basement walk-ups, per its [2026 user fees](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING). You pay it with the permit and get it back later, so budget the cash even though it isn't a cost. Ask the City what releases it before you apply.

The same schedule has a separate, larger deposit line for new houses and some additions, so a basement job done alongside an addition may fall under different rules. Pickering is the only one of the five towns where we found a basement deposit.

## How long does a basement permit take in Durham?

The Code sets the clock, and it only starts once your application is complete. For a house where no dwelling unit sits above another, the chief building official has 10 days to issue the permit or refuse it in writing with reasons, under Div. C 1.3.1.3. of the [2024 Building Code](https://www.publications.gov.on.ca/301880). Those days don't count Saturdays, holidays or days the office is closed (1.3.1.3.(8)). A house with a basement apartment likely falls in the 15-day category. An incomplete application has no clock running at all.

Oshawa warns on its [building permits page](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/) that "we cannot guarantee review timeframes will be met" because of record volume. Plan for some slack in any town, and don't book trades for the day after you apply.

## How we handle basement permits

We're Jarvis Contracting, a family design-build firm based in Ajax. James Jarvis runs construction and his wife, Ceara Jarvis, runs design through her studio Juliette Interiors. We draw permit drawings in-house and build basements and additional units, so the drawings the town reviews are the ones our crew builds from. We plan, draw and build to the Ontario Building Code; the town reviews the drawings and inspects the work.

On a permitted job the walls stay open until the town's framing and insulation inspections pass, and we schedule the trades around those visits. See our [basement renovations page](https://www.jarviscontracting.ca/basement-renovations) for how a basement job runs from measurement to final inspection.

## Questions

### Do I need a permit to finish a basement in Whitby?

Finishing a basement in Whitby needs a building permit, because Ontario's Building Code Act requires a permit to construct and the Code doesn't exempt basement work. Whitby's 2026 Schedule N has no separate basement line; the $10.65 per m2 interior alteration rate likely applies, which is about $693 for 700 sq ft by our calculation.

### How much is a basement finishing permit in Oshawa?

Oshawa charges $7.79 per m2 to finish a basement in 2026, on the greater of the actual floor area or 50 m2. A 700 sq ft basement works out to about $507 by our calculation, and the minimum for any basement is about $390. Oshawa raised its fees 3% on 1 January 2026.

### Does Ajax charge a separate fee for a basement entrance?

Ajax charges for a basement entrance separately. Its 2026 Schedule A lists a $329 fee for a below-grade entrance (line B10), separate from the floor-area fee. Ajax doesn't print an explicit basement finishing line, so ask the Town whether the $7.16 interior alteration rate (B5) applies to your basement.

### What is the $1,000 deposit for a basement permit in Pickering?

Pickering's $1,000 basement deposit is a refundable performance deposit, effective 6 January 2026, charged on finished basements, secondary suites and basement walk-ups. It's on top of the $7.37 per m2 permit fee. Ask the City what's needed to release it before you apply.

### Do I need a permit to finish a basement in Clarington?

A basement finish in Clarington needs a building permit, like anywhere in Ontario. Clarington has no named basement line in By-law 2024-006, so the $5.48 per m2 interior alteration rate likely applies, about $356 for 700 sq ft by our calculation, and the rate rises 3% each 1 January.

### What happens if I finished my basement without a permit in Durham Region?

A basement finished without a permit in Durham Region can draw a surcharge when you do apply: 50% of the fee in Oshawa and Clarington if no application was made, and the greater of $100 or 25% in Whitby. The larger cost is usually opening walls so the framing, insulation and plumbing can be inspected.

# Fixed price vs cost-plus contracts for Ontario renovations

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

A fixed-price contract sets the total before work starts, so the contractor carries the risk of costs running over and builds that risk into the price. A cost-plus contract pays the actual cost plus a fee, so you carry the risk and see every invoice. As of October 2026, if your contract rests on an estimate, Ontario caps the final price at 10% over it unless you agree to new work or a new price ([Ontario, your rights when starting home renovations](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). Jarvis Contracting works fixed price, and the last section says how.

## Key takeaways

- Ontario says the final price "cannot be more than 10% over the original estimate" unless you've agreed to new work or a new price, as of October 2026 ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Ontario recommends a deposit of no more than 10%, which caps it at $18,000 on a $180,000 rear addition, the low end of our 2026 range (calculated; [Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Under either contract you must hold back 10% of the value of work supplied until liens expire, and you can pay up to 90% without risk unless you get written notice of a lien ([Construction Act ss. 22(1) and 24(1)](https://www.ontario.ca/laws/statute/90c30)).
- A contractor's lien expires 60 days after the earlier of publication of substantial performance or the contract being completed, abandoned or terminated ([Construction Act s. 31(2)](https://www.ontario.ca/laws/statute/90c30)).
- Jarvis Contracting works fixed price: the whole project is priced and the contract signed, with a 10% deposit, before design begins, and any change to the price goes through a change order you sign.

## How does a fixed-price contract price risk?

A fixed price moves the risk of overruns to the contractor, and the contractor charges for carrying it. If framing takes longer than planned or lumber costs more than expected, that's the builder's problem, as long as the work is inside the agreed scope.

So the price includes a cushion you can't see. On a RedFlagDeals thread about choosing a builder, one reply warned that fixed prices carry a hefty contingency for exactly this reason (paraphrased; [RedFlagDeals, 2018](https://forums.redflagdeals.com/choosing-builder-custom-home-2206163/)). That isn't a scam. It's the price of certainty, and on a well-drawn job it's often worth paying.

A fixed price is only as firm as the scope behind it. It needs a defined scope: drawings or a detailed written list of what's included, the finish level and the allowances. Read the exclusions and the allowances: an allowance is a placeholder sum for something not yet chosen, like tile or a vanity, and if you pick something dearer, you pay the difference. Unknown conditions are the other gap. Rot under a floor, an old wiring run or a foundation that isn't what the drawings assumed are often carved out of the fixed price and charged as extras.

## How does a cost-plus contract work?

Cost-plus means you pay what the job actually costs, labour, materials and sub-trades, plus a fee to the contractor. The fee is either a percentage of cost or a fixed sum agreed up front.

The appeal is openness: you see the invoices, nothing is padded for risk, and you pay only for what happens. The worry is incentive, and the same RedFlagDeals thread raised it: under cost-plus, the builder has no built-in reason to chase cheaper bids (paraphrased; [RedFlagDeals, 2018](https://forums.redflagdeals.com/choosing-builder-custom-home-2206163/)). A percentage fee makes that worse, since the fee grows with the cost. A fixed fee, or a cost-plus contract with an agreed upper limit, fixes most of it.

Cost-plus also needs more of you. You have to read invoices, ask about variances and make decisions quickly, because time is cost.

Here's how the two compare on the points that matter for an addition or renovation:

| Point | Fixed price | Cost-plus |
|---|---|---|
| Who carries overruns inside the scope | The contractor | You |
| Contingency | Built into the price, hidden from you | Your money, held by you until it's spent |
| When you know the number | At signing, for the defined scope | At the end; you get estimates along the way |
| What you see | The price and the payment schedule | Every invoice, plus the fee |
| Changes | Priced one at a time as change orders | Added to the running cost, plus the fee |
| Needs before signing | A defined scope, drawn or written, with allowances | A trusted builder and a budget estimate |
| Main risk to you | Extras for exclusions, allowances and unknowns | Costs drifting with no ceiling |

Note: This table compares the two structures in general; a real contract can mix them, for example a fixed price with cost-plus pricing for unknown conditions.

## How much contingency should you carry?

There's no universal percentage for a renovation contingency, so we won't print one.

What drives the right number is how much you don't know. An older house with walls still closed, drawings still changing and finishes not yet picked needs more. A fully drawn addition on a newer house needs less. Under a fixed price, the contractor's contingency sits inside the price, but you still want your own reserve for changes you decide to make. Under cost-plus, the whole contingency is yours.

## Can a contractor charge more than the estimate in Ontario?

Not by more than 10%, unless you agree to new work or a new price, as of October 2026 ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). The same page says new work should come as a change you "approve and sign", including a new estimate.

That makes the change order the most important page in either contract. Every change should be written down, priced and signed before the work happens, with its effect on the schedule. A verbal "go ahead" on site is how budgets slip, under either model. Any renovation contract over $50 has to be in writing in the first place.

## How much deposit should you pay, and how should payments run?

Ontario recommends a deposit of no more than 10% and warns against large down payments "to pay for materials" ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). The risk is real: in July 2026, the Toronto news channel CP24 reported a Brampton owner who paid $33,000, about 90% of the contract, for a basement apartment left unfinished ([CP24, 9 July 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)).

After the deposit, tie payments to stages you can see: foundation in, framing done, roof on, rough-ins inspected, drywall up. Section 22(1) of the [Construction Act](https://www.ontario.ca/laws/statute/90c30) requires you to retain 10% of the value of services and materials as they're supplied, and section 22(3) applies it whether you pay in instalments or at the end. On a $180,000 contract, that's $18,000 held until the 60-day lien period under section 31(2) has passed (calculated). Section 23 limits your personal liability to lien claimants to the holdback you were required to keep, which is why skipping it is a bad idea.

Since 1 January 2026, section 26 also requires an owner whose contract runs past its anniversary to publish a notice within 14 days of that date. The owner then releases the accrued holdback 60 to 74 days after the notice, unless a lien has been preserved. Our [Greenwood](https://www.jarviscontracting.ca/projects/greenwood) job, a rear extension plus a new top storey, took 10 months including design, permits and construction, so many addition contracts end before their first anniversary, but a long whole-home job may not.

Here's what the contract should say, under either pricing model:

| Clause | What it should say | Where it comes from |
|---|---|---|
| Contractor details | Name, address and contact information | [Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) |
| Scope | A thorough description of the work and materials, tied to the drawings | Ontario's renovation rights page |
| Price | A fixed sum, or the cost-plus fee and how costs will be shown to you | Good practice |
| Allowances and exclusions | Each allowance amount, and what happens with unknown conditions | Good practice |
| Changes | Written, priced and signed before the work, with the schedule effect | Ontario's renovation rights page |
| Deposit and payments | Deposit of no more than 10%, then stage payments | Ontario's renovation rights page |
| Holdback | 10% retained until liens expire | [Construction Act s. 22(1)](https://www.ontario.ca/laws/statute/90c30) |
| Dates | Start and completion dates | Ontario's renovation rights page |
| Warranties | What's covered and for how long | Ontario's renovation rights page |
| Sub-trades and cleanup | Which trades are subcontracted, and who cleans up | Ontario's renovation rights page |
| Permits | Who files, who pays the fees and who answers the examiner | Good practice |

Note: This is a checklist of contents, not a template contract; for a large job, have a lawyer read it before you sign.

## Which contract suits your job?

A fixed price suits a job with a defined scope and a lender or a budget that needs one number. That's most additions.

Cost-plus suits a job where the unknowns are large and can't be priced fairly up front: a century house with walls still closed, a repair whose extent you'll only see once you open it, or a project you want to start before every decision is made. It works best with a builder you already trust, a fixed fee and an agreed ceiling.

Check what's outside both prices. In Whitby, in Durham Region, Ontario, the 2026 permit rate for additions is $22.37 per m2. For a 1,000 sq ft addition that works out to about $2,078 (calculated from [Whitby's 2026 Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)), and a minor variance adds a $1,526 application ([Whitby's minor variance application](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf)). The contract should say who pays them.

## How we work

We work fixed price. We design and build under one contract, with design in-house: Ceara Jarvis leads design through Juliette Interiors, we draw the permit drawings, and James Jarvis runs construction. The whole project is priced and the contract signed, with a 10% deposit, before design begins. Design then works to that price, and any change to the price goes through a change order you sign, so the number you signed only moves when you sign again. Our [design-build](https://www.jarviscontracting.ca/design-build) and [process](https://www.jarviscontracting.ca/process) pages set out the steps. If you're still choosing how to hire, read [design-build vs an architect plus a general contractor](https://www.jarviscontracting.ca/guides/design-build-vs-general-contractor) first, and take the checklist in [questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor) to every meeting.

## Questions

### Is fixed price or cost-plus cheaper for a renovation in Ontario?

Neither is reliably cheaper for an Ontario renovation. A fixed price includes a contingency for risks the contractor carries, so you pay for certainty. Cost-plus has no built-in cushion, so it can come in lower, but nothing stops it running higher if the job grows.

The more complete your drawings and scope, the less the fixed-price cushion needs to be, and the stronger the case for a fixed price.

### Can a contractor charge more than the estimate in Ontario?

A contractor in Ontario can't charge more than 10% over the original estimate unless you agree to new work or a new price, as of October 2026. The province says new work should come as a signed change to the contract, with a new estimate.

Get every change in writing, priced, before the work is done.

### What is a fair fee on a cost-plus renovation contract?

There's no credible published figure for a typical cost-plus fee on an Ontario renovation, so we won't give one. Ask each builder for the fee in writing, and ask whether it's a percentage of cost or a fixed sum.

A fixed fee eases the incentive problem, since the builder earns the same however much the job costs.

### Do I have to hold back 10% on a renovation in Ontario?

Yes. Section 22(1) of Ontario's Construction Act requires each payer under a contract where a lien may arise to retain 10% of the value of services and materials supplied, whether you pay in stages or at the end.

You release it once the lien period has passed: for a contractor, 60 days after the earlier of publication of substantial performance or the contract being completed, abandoned or terminated.

### How much deposit should I pay a contractor in Ontario?

Ontario recommends a renovation deposit of no more than 10% of the contract, as of October 2026, and warns against large down payments for materials. On a $180,000 addition, that's $18,000 at most.

After that, pay in stages tied to work you can see and that's been inspected where an inspection applies.

### What is an allowance in a renovation contract?

An allowance is a placeholder sum in a renovation contract for something not yet chosen, such as flooring, tile or light fixtures. If what you pick costs more than the allowance, you pay the difference, and if it costs less, you should get a credit.

Low allowances make a fixed price look cheaper than it is, so compare them line by line across quotes.

# HCRA licence and Tarion warranty: who needs them in Ontario

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-05.

In Ontario, anyone who builds or sells a new home, including a custom home on your own land, must hold a licence from the Home Construction Regulatory Authority (HCRA), and the home is covered by Tarion's warranty of up to $400,000 ([HCRA](https://www.hcraontario.ca/do-i-need-a-licence/); [Tarion](https://www.tarion.com/node/66068)). Renovations and additions to an existing house typically need neither. Coach, laneway and tiny homes sit in between: HCRA says they "generally require licensing and warranty coverage". These are the rules as of October 2026.

## Key takeaways

- HCRA says "all new home builders and sellers are required by law to be licensed", and a builder of a custom or contract home on the owner's land must be licensed as both vendor and builder ([HCRA licensing page](https://www.hcraontario.ca/do-i-need-a-licence/)).
- Renovations and upgrades "typically" don't make a home new and don't require a licence; HCRA says renovators "aren't licensed or regulated like new home builders" ([HCRA on renovators](https://www.hcraontario.ca/resources/finding-a-renovator/)).
- A Tarion-backed contract home gets 1, 2 and 7-year warranties up to $400,000, plus up to $40,000 if the builder defaults before completion ([Tarion on contract homes](https://www.tarion.com/node/66068)).
- Tarion excludes "alterations, deletions or additions made by the homeowner", so a later addition to a warranted house isn't covered by that warranty ([Tarion exclusions](https://www.tarion.com/homeowners/what-is-not-covered)).
- An owner-built home may not need a licence if it isn't sold, but it gets no statutory warranty at all ([HCRA licensing page](https://www.hcraontario.ca/do-i-need-a-licence/)).
- Every construction business needs WSIB coverage with limited exceptions, and the home renovation exemption covers only the owner-operator, never their workers or subcontractors ([WSIB Policy 12-01-06](https://www.wsib.ca/en/operational-policy-manual/expanded-compulsory-coverage-construction)).

## What is the HCRA, and who has to be licensed?

The HCRA is Ontario's regulator for new home builders and sellers. Its rule is short: "all new home builders and sellers are required by law to be licensed" ([HCRA licensing page](https://www.hcraontario.ca/do-i-need-a-licence/)). That covers builders, vendors, and anyone who builds a custom or contract home on land the client already owns. In that last case the builder needs both licences, vendor and builder.

What makes something a "home" for the HCRA is what's in it. The regulator lists heating, insulation, electricity, potable water, plumbing or waste disposal, together with sleeping and cooking areas ([HCRA licensing page](https://www.hcraontario.ca/do-i-need-a-licence/)). You can check any builder in the [HCRA Ontario Builder Directory](https://obd.hcraontario.ca/).

## Does my renovation or addition contractor need an HCRA licence?

No, typically not. HCRA says renovations or upgrades to an existing home "do not make the home new" and "do not require the builder to be licensed" ([HCRA licensing page](https://www.hcraontario.ca/do-i-need-a-licence/)). Its renovator page goes further: renovators "aren't licensed or regulated like new home builders and sellers are" ([HCRA on renovators](https://www.hcraontario.ca/resources/finding-a-renovator/)).

So a renovator, an addition contractor or a basement finisher won't show up in the builder directory, and that's not a red flag. Some contractor blogs list a missing HCRA licence as a warning sign for renovators. For a renovation it's the wrong test. The checks that do apply are a written contract, WSIB, insurance, licensed electrical and gas trades, and a building permit, which our [questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor) guide walks through.

Here's how the rules fall across common projects:

| Project | HCRA licence needed? | Tarion warranty? | Source |
|---|---|---|---|
| New custom home on your land, built by a contractor | Yes, vendor and builder | Yes, as a contract home | [HCRA](https://www.hcraontario.ca/do-i-need-a-licence/); [Tarion](https://www.tarion.com/node/66068) |
| New house bought from a builder | Yes | Yes | [HCRA](https://www.hcraontario.ca/do-i-need-a-licence/) |
| Home you build yourself, for your own use, not sold | May not be needed | No statutory warranty | [HCRA](https://www.hcraontario.ca/do-i-need-a-licence/) |
| Detached coach house, laneway or garden suite with kitchen and sleeping area | Generally yes | Generally yes | [HCRA](https://www.hcraontario.ca/do-i-need-a-licence/) |
| Rear addition or second storey on an existing house | Typically no | No | [HCRA](https://www.hcraontario.ca/do-i-need-a-licence/) |
| Basement apartment inside an existing house | Typically no (a renovation) | No | [HCRA](https://www.hcraontario.ca/do-i-need-a-licence/) |
| Kitchen, bathroom or whole-home renovation | No | No | [HCRA on renovators](https://www.hcraontario.ca/resources/finding-a-renovator/) |

Note: summary of the HCRA and Tarion pages as of October 2026; "typically" and "generally" are the regulator's own words, and the HCRA decides edge cases, so ask it directly about a borderline project.

## Why do garden suites and coach houses "generally" need a licence?

Because a detached unit with its own heat, plumbing, kitchen and bedroom ticks every box on the HCRA's list of what makes a home. HCRA says "Coach, laneway, and 'tiny' homes generally require licensing and warranty coverage" ([HCRA licensing page](https://www.hcraontario.ca/do-i-need-a-licence/)). The word "generally" matters: it leaves room for cases the regulator decides on their facts.

This is live in Durham Region, Ontario, where towns now allow a detached additional dwelling unit on most urban lots. Whitby caps a detached unit at 75 m² and 4.5 m high ([Whitby Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf)), Oshawa at 60 m² of ground floor in most zones ([Oshawa accessory apartments page](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/)), and Pickering allows up to 150 m² subject to other limits ([Pickering Zoning By-law 8149/24](https://corporate.pickering.ca/WebLink/DocView.aspx?id=258309&dbid=1&repo=PICKERING)). A building permit and the town's zoning answer whether you can build one. The HCRA answers who may build it for you. Before you sign for a garden suite, ask the builder in writing how the HCRA's coach-house guidance applies to your project, and check the answer in the directory or with the HCRA. Our [Bill 23 units guide](https://www.jarviscontracting.ca/guides/bill-23-additional-units-ontario) covers what each town allows.

## What does Tarion cover, and for how long?

Tarion backs the statutory warranty on new homes, including contract homes built on the owner's land. For a contract home, coverage is the 1, 2 and 7-year warranties up to $400,000 once the contract is substantially performed, plus up to $40,000 if the builder defaults before completion ([Tarion on contract homes](https://www.tarion.com/node/66068)).

The three warranty periods cover different things:

| Warranty | What it covers (summary) | Source |
|---|---|---|
| 1 year | Work done in a workmanlike manner and free of defects in materials; Building Code violations; fit to live in | [Tarion coverage](https://www.tarion.com/homeowners/coverage-freehold-contract-condo-units-condo-conversions) |
| 2 years | Water through the basement or foundation walls and the building envelope; defects in electrical, plumbing and heating distribution; detached cladding; Code health and safety violations | [Tarion coverage](https://www.tarion.com/homeowners/coverage-freehold-contract-condo-units-condo-conversions) |
| 7 years | Major structural defects, from the date you take possession | [Tarion coverage](https://www.tarion.com/homeowners/coverage-freehold-contract-condo-units-condo-conversions) |
| Contract home deposit | Up to $40,000 of financial loss if the builder defaults before completion | [Tarion on contract homes](https://www.tarion.com/node/66068) |

Note: a plain-language summary of Tarion's pages as of October 2026, not the wording of the warranty; the $400,000 cap is for a contract home, and Tarion's own pages set the exact terms and claim deadlines.

If you supply a core part of a contract home yourself, such as the foundation, framing or mechanical work, the home may be treated as owner-built and lose the statutory warranty ([Tarion on contract homes](https://www.tarion.com/node/66068)). The builder also pays an enrolment fee per home: $2,075 plus HST for a home priced between $950,000 and $1,000,000, as of September 2025 ([Tarion enrolment fees](https://www.tarion.com/builders/enrolment-fees)).

## Does Tarion cover renovations or additions?

No. Tarion's warranty attaches to new homes, and its list of exclusions names "alterations, deletions or additions made by the homeowner" ([Tarion exclusions](https://www.tarion.com/homeowners/what-is-not-covered)). An addition built on a house you already own is a renovation, so there's no Tarion enrolment and no statutory warranty. If your house is still inside its own Tarion warranty period, remember that exclusion: defects tied to your addition won't be Tarion's, so ask Tarion before the work starts.

What protects you on a renovation is contract law. Ontario requires a written contract for renovation work over $50, recommends a deposit of no more than 10%, and caps the final price at 10% over the estimate unless you approve extra work in writing ([Ontario renovation rights](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). The Construction Act has you hold back 10% of each payment until the lien period ends ([Construction Act s.22](https://www.ontario.ca/laws/statute/90c30)). Any workmanship warranty is whatever your contract says, so get it in writing. Our [fixed price vs cost-plus guide](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus) covers what that contract should contain.

## Where does WSIB fit in?

WSIB is separate from both. It's workplace insurance, and the WSIB says people who own or run a construction business "must have coverage" with some exceptions ([WSIB compulsory coverage](https://www.wsib.ca/en/businesses/registration-and-coverage/expanded-compulsory-coverage-construction-industry)). One exception is narrow: an owner-operator doing only home renovation work directly for the person who lives in the house is exempt for themselves. Their workers and their subcontractors still have to be covered ([WSIB Policy 12-01-06](https://www.wsib.ca/en/operational-policy-manual/expanded-compulsory-coverage-construction)). Building a new home isn't exempt renovation work.

If you hire a contractor for construction work, WSIB policy says the person who hires the contractor must get a clearance certificate before work starts; clearances last up to 90 days. Without one you can be liable for the contractor's unpaid premiums up to the labour portion of the contract. Homeowners hiring only for exempt home renovation work are excluded from that rule ([WSIB clearance policy 14-02-19](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction)). Asking for the certificate costs nothing either way.

## How we fit in

We're a design-build renovation firm in Ajax: additions, second storeys, basements and additional units, with design in-house through Juliette Interiors. For the additions and renovations that make up that work, the HCRA and Tarion rules above don't apply, so the protections that count are the contract, the permit and the people on site. Ask us, and anyone else you're talking to, for the WSIB status, the insurance certificate and the written terms before you sign. See our [home additions page](https://www.jarviscontracting.ca/home-additions) and garden suites page for how we take on each kind of job.

## Questions

### Does a renovation contractor need an HCRA licence in Ontario?

A renovation contractor typically doesn't need an HCRA licence in Ontario. The HCRA says renovations or upgrades to an existing home don't make it a new home, and that renovators aren't licensed or regulated like new home builders.

### Does Tarion cover home additions or renovations?

Tarion doesn't cover additions or renovations to an existing house. Its warranty attaches to new homes, and it excludes alterations and additions made by the homeowner, so your protection on a renovation comes from your written contract and Ontario's consumer protection rules.

### Do I need an HCRA-licensed builder for a garden suite or coach house?

The HCRA says coach, laneway and tiny homes generally require licensing and warranty coverage, because a detached unit with heating, plumbing, a kitchen and sleeping space meets its definition of a home. Ask the HCRA directly if your project is borderline.

### Do I need an HCRA-licensed builder for a custom home on my own lot?

Yes. A builder who builds a custom or contract home on land you own must be licensed by the HCRA as both vendor and builder, and the home is enrolled with Tarion for the 1, 2 and 7-year warranties up to $400,000.

### What happens if I build my own home in Ontario?

An owner who builds a home for their own use and doesn't sell it may not need an HCRA licence, but the home has no statutory warranty. Tarion may also treat a contract home as owner-built if the owner supplies core parts such as the foundation or framing.

### Does my renovation contractor need WSIB coverage in Ontario?

Construction businesses in Ontario must have WSIB coverage, with some exceptions. An owner-operator doing only home renovation work directly for the occupant is exempt for themselves, but their workers and subcontractors must still be covered.

# How many units can I add to my lot in Ontario?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-05.

Three. On urban residential land in Ontario, the [Planning Act](https://www.ontario.ca/laws/statute/90p13), as changed by Bill 23 in November 2022, stops any town from prohibiting three units on a lot: three in the house, or two in the house and one in a backyard building. As of October 2026 several towns allow more, including Whitby and Ajax in Durham Region, Ontario, where four homes can share a lot, and Toronto, which allows four citywide and six in parts of the city.

## Key takeaways

- Under section 35.1 of the [Planning Act](https://www.ontario.ca/laws/statute/90p13), a town can't prohibit 3 units on urban residential land, or require more than 1 parking space per added unit.
- Whitby allows up to 3 additional dwelling units, 4 homes in all, with a backyard unit of up to 75 m2, per [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf).
- Pickering caps a lot at 2 additional units, but its backyard unit can reach 150 m2, per [Zoning By-law 8149/24](https://corporate.pickering.ca/WebLink/DocView.aspx?id=258309&dbid=1&repo=PICKERING).
- A 2nd or 3rd unit in an existing house pays no development charges under section 2(3.2) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27).
- Durham Region issued permits for 1,004 additional residential units in 2025, up from 999 in 2024, per the Region's [2025 building activity review](https://media-003-ca.cdn.govstack.com/durham-ca/media/vc5lqmuu/2026-info-54-2025-annual-building-activity-review.pdf).

## What does Bill 23 let you build on your lot?

Bill 23 set a provincial minimum of three units on urban residential land, and towns can only add to it. "Urban residential land" means a lot inside a settlement area that's on municipal water and sewer. On that land, as of October 2026, section 35.1 of the [Planning Act](https://www.ontario.ca/laws/statute/90p13) says a zoning by-law can't prohibit either layout:

- three units inside the house, or
- two units inside the house plus one in an ancillary building, such as a garden suite or a unit over a garage.

The same section says zoning can't demand more than one parking space per added unit, and can't set a minimum unit size. [O. Reg. 299/19](https://www.ontario.ca/laws/regulation/190299) adds that anyone can live in the units, related to you or not, and that the age of the house doesn't matter.

Two later regulations loosened things further. Since 20 November 2024, a lot with additional units can cover at least 45% of its area, faces no floor space index limit, and can't be made to keep more than 4 m between residential buildings on the lot (O. Reg. 462/24). Since 21 November 2025, urban residential setbacks are deemed to be 90% of the by-law figure, except near shorelines, wetlands, valleys and railways and in the Greenbelt, under [O. Reg. 545/06](https://www.ontario.ca/laws/regulation/060545). Site plan control doesn't apply to a lot of 10 units or fewer unless it's in a prescribed area.

## How many units does each Durham town allow?

Durham's five lakeshore towns split two ways: Whitby and Ajax allow four homes on a lot, while Oshawa, Pickering and Clarington stop at three. As of October 2026, here's what each zoning by-law or town page allows on a typical serviced lot:

| Town | Homes on one lot | Backyard unit limits | Source |
|---|---|---|---|
| Whitby | 4: up to 3 ADUs, either 2 in the house plus 1 accessory, or 3 in the house; 1 ADU on Moraine and Greenbelt lots | 75 m2 GFA, 4.5 m high, 1.2 m interior side and rear setbacks | [Whitby By-law 1784, s.4](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) |
| Oshawa | 3, with at most 1 in an accessory building | All accessory buildings capped by 8% of lot area, 50% of house coverage or 60 m2 of ground floor (90 m2 in R1-G and R1-H); 4.5 m high; 0.6 m side and rear | [Oshawa accessory apartments page](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/) |
| Ajax | 4: up to 3 attached ADUs, or 2 attached plus 1 detached | At least 3.0 m from other buildings; ground floor smaller than the house; 45% lot coverage with an ADU | [Ajax By-law 95-2003, s.4.4](https://ajax.ca/wp-content/uploads/2026/04/4-Section-4-General-Provisions_2026-March-Consolidation-Final.pdf) |
| Pickering | 3: 2 ADUs in the house, or 1 in the house plus 1 accessory; 1 on the Moraine | Lesser of 150 m2 or 50% of the house's GFA; 4.5 m high on lots up to 2,000 m2; 1.2 m side and rear | [Pickering By-law 8149/24, s.4.3.1](https://corporate.pickering.ca/WebLink/DocView.aspx?id=258309&dbid=1&repo=PICKERING) |
| Clarington | 3 in Courtice, Bowmanville, Newcastle and Orono: 1 in the house plus 1 accessory; 1 on Moraine and Greenbelt land | 1.8 m rear and interior side setbacks; 5.25 m high in urban zones; smaller than the house | [Clarington ADU page](https://www.clarington.net/homes-and-property/building-or-renovating/additional-dwelling-units/) |

Note: these are general rules for serviced lots as of October 2026; hazard lands and site-specific zoning can cut them back.

The backyard unit's size matters as much as the count: Pickering's 150 m2 ceiling is double Whitby's 75 m2. Where a town's page describes fewer layouts than the Planning Act guarantees, as Clarington's does, the provincial layouts still apply on urban residential land; ask the planning department.

Many north Durham lots are on wells and septic, outside the provincial three-unit rule. Scugog allows up to two ADUs in settlement areas such as Port Perry, per its [ADU page](https://www.scugog.ca/building-development/additional-dwelling-units/). Uxbridge permits a two-unit house wherever a single, semi or row house is allowed, per its [zoning by-law](https://www.uxbridge.ca/public/download/files/311355). Brock allows two units in the house, or one in the house and one in an accessory building, per its [zoning by-law](https://media-002-ca.cdn.govstack.com/townshipofbrock-011-ca/media/xdgpvtpk/zbl-287-78-pl_2026-section-6-eq.pdf).

## How many units do GTA towns allow?

Across the rest of the GTA, the count runs from three to six. As of October 2026, each row was checked against the by-law or town page it links to:

| Town | Homes on one lot | Backyard unit limits | Source |
|---|---|---|---|
| Toronto | 4 as of right citywide in R, RD, RS, RM and RT zones; 6 in Toronto and East York and Ward 23 ([sixplex rules](https://www.toronto.ca/city-government/planning-development/planning-studies-initiatives/multiplex-housing/)) | Garden suite up to 120 m2 GFA (60 m2 if one storey), 2 storeys, smaller than the house | [Toronto multiplex rules](https://www.toronto.ca/city-government/planning-development/planning-studies-initiatives/multiplex-housing/considerations-when-building-multiplexes/) |
| Mississauga | 3: 2 attached ARUs, or 1 attached plus 1 garden suite; new fourplexes in RL, RS and R16 zones | 55 m2 on lots up to 550 m2, otherwise 10% of lot area up to 100 m2 | [Mississauga zoning, Part 4](https://www7.mississauga.ca/Departments/PB/ZoneBylaw/DZBR1/Part%204%20-%20General%20Provisions.pdf) |
| Brampton | 3, including the house: the house plus 2 attached units, or 1 attached unit and 1 garden suite | Units must be registered with the City | [Brampton second units page](https://www.brampton.ca/EN/residents/Building-Permits/second-dwelling) |

Note: these are summaries of each town's general rule for a serviced lot as of October 2026, not a check of your property; Oak Ridges Moraine, Greenbelt and floodplain lots usually get fewer units or none.

## Is a third unit harder to build than a second?

It can be, because the Building Code treats the house differently once it holds three units. The [2024 Building Code](https://www.publications.gov.on.ca/301880) defines a secondary suite as a unit in a building that holds only one other dwelling unit (Div. A 1.4.1.2.). Several easier rules, such as the Type X drywall alternative to a rated fire separation, apply to a "house with a secondary suite". Add a third unit inside the same house and those shortcuts may no longer fit, so talk to the building department before you design around them.

A third unit in a backyard building avoids that problem, since the house still holds two. Our [requirements guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario) lists the Code rules for a two-unit house, and the [cost guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) prices a basement unit.

## Do additional units pay development charges?

No, within the provincial limits. As of October 2026, a second or third unit in an existing house, or one unit in an ancillary building, pays no development charges under section 2(3.2) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27), and section 2(3.3) does the same for new houses.

Whitby notes one exception on its [ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/): education development charges still apply to a detached ADU. Whitby's Housing Accelerator Fund incentive reimburses them, along with the permit and entrance fees, for complete applications made by 31 December 2026. See our [Whitby ADU incentive guide](https://www.jarviscontracting.ca/guides/whitby-adu-incentive), and [basement permits in Durham Region](https://www.jarviscontracting.ca/guides/basement-permits-durham-region) for each town's permit fees.

## What still limits what you can build?

Setbacks, height and the land itself still limit you. Oak Ridges Moraine lots in Whitby, Pickering and Clarington drop to one additional unit, and so do Greenbelt lots in Whitby and Clarington. Land regulated by a conservation authority needs its permit too: Whitby and Oshawa sit under Central Lake Ontario Conservation (CLOCA), and Ajax and Pickering under both CLOCA and the Toronto and Region Conservation Authority. Ajax bars ADUs on lands its conservation authority marks as hazardous, per [By-law 95-2003](https://ajax.ca/wp-content/uploads/2026/04/4-Section-4-General-Provisions_2026-March-Consolidation-Final.pdf).

If your plan misses a setback or a height limit, you need a minor variance from the Committee of Adjustment. In 2026 the residential fee is $1,526 in [Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf), $856 per lot in [Oshawa](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/), $2,500 in [Pickering](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING) from 1 July 2026, and $2,280 in [Clarington](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=455554&dbid=0&repo=Clarington). Ajax charged $1,638.90 for a single residential variance in its [2025 user fees](https://ajax.ca/wp-content/uploads/2026/03/By-law-61-2024-2025-User-Fees-By-law.pdf); we didn't find a 2026 schedule.

## How we help you decide what to add

We're Jarvis Contracting, a family design-build firm based in Ajax. James Jarvis runs construction and his wife, Ceara Jarvis, runs design through her studio Juliette Interiors. We draw permit drawings in-house and build basements and additional units, so we can lay out a basement suite and a garden suite on one lot and show you what each needs before you commit. The town reviews the drawings and issues the permit. See garden suites, [basement renovations](https://www.jarviscontracting.ca/basement-renovations) and how our [design-build](https://www.jarviscontracting.ca/design-build) process runs.

## Questions

### How many units can I build on my lot in Whitby?

As of October 2026, Whitby allows up to three additional dwelling units on a serviced residential lot, four homes in all. They can be two in the house plus one in an accessory building, or three in the house. A backyard unit is capped at 75 m2 of floor area and 4.5 m in height, and Moraine or Greenbelt lots get one additional unit only.

### Does Bill 23 apply to rural lots in Ontario?

Bill 23's three-unit rule applies only to urban residential land, meaning a lot inside a settlement area on municipal water and sewer. Rural lots on wells or septic depend on the town's own zoning. In north Durham, Scugog allows up to two additional units in settlement areas such as Port Perry, and Uxbridge allows a two-unit house.

### Can I have a basement apartment and a garden suite on the same lot in Ontario?

A basement apartment and a garden suite can share a lot. On urban residential land the Planning Act stops a town from prohibiting two units in the house plus one in a backyard building. Each town still sets the garden suite's size, height and setbacks, from 75 m2 in Whitby to 150 m2 in Pickering.

### Do I need extra parking for an additional unit in Ontario?

A town can require at most one parking space for each additional unit under section 35.1 of the Planning Act, and some require none. Whitby waives parking for units in a Protected Major Transit Station Area, and Burlington asks for none for the first additional unit.

### Can I rent an additional unit to someone who isn't family?

An additional unit in Ontario can be rented to anyone. Ontario Regulation 299/19 lets anyone live in an additional residential unit, related to the owner or not, and it applies however old the house is.

# How much does a home addition cost in Ontario in 2026?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

We price a home addition at $350 to $600 per square foot in 2026, and a single-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000, before HST. Your own price comes after James sees the house, and the first estimate is free. In Durham Region, Ontario, the town's share is small by comparison: a 500 sq ft addition pays a building permit of $661 to $1,039 under the 2026 schedules, and no development charges, as of October 2026.

## Key takeaways

- Our 2026 range for additions of all types is $350 to $600 a square foot, and $60,000 to $180,000 for a 100 to 300 sq ft bump-out, before HST.
- An addition that only enlarges your home pays no development charges, because the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27) carves out "the enlargement of an existing residential unit" (as of October 2026).
- A 1,000 sq ft addition pays a building permit of $1,321 in Ajax and $2,078 in Whitby, calculated from the [Town of Whitby's 2026 Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) and Ajax's 2026 schedule.
- Our permit drawings for an addition are $6,000 to $12,000. That's drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra.
- Pickering asks for a refundable performance deposit of $2,379 on additions over 60 m2, about 646 sq ft, in its [2026 user fee schedule](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING), which also lists a separate $1,000 deposit for additions.
- We don't give a set range for a garage addition, so price one from its parts; the permit is $10.65 per square metre in Whitby under [Schedule N's garage line](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf).

## What does a home addition cost per square foot in Ontario?

We price a home addition at roughly $350 to $600 per square foot in 2026, before HST. That's our range across all types of addition, and where yours lands depends on its type, size and finish.

Here are our 2026 ranges by type of addition:

| Type of addition | Typical size | Our 2026 range |
|---|---|---|
| Bump-out | 100 to 300 sq ft | $60,000 to $180,000 |
| Rear addition, one storey | 300 to 700 sq ft | $180,000 to $450,000 |
| Second storey | 600 to 1,200 sq ft | $300,000 to $800,000, plus any work on the floor below |
| Side addition | varies | no set range |
| Garage addition | varies | no set range |

Note: these are our ranges before 13% HST, not quotes; your price comes after James sees the house, and the first estimate is free. A row with no set range is priced from the site visit; it doesn't mean the work is cheap.

Small additions cost more per square foot than big ones. Excavation, a foundation, a roof tie-in, drawings and a permit cost roughly the same whether the room is small or large, so they weigh heavier on a small one. That's why a bump-out of 100 to 300 sq ft still starts at $60,000 in our range.

Second storeys get their own guide, because the main floor below changes the math. See [what a second-storey addition costs in Ontario](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario).

## What does a rear addition cost?

We price a one-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000 before HST in 2026. The low end is a simple box off the back wall on a slab or crawl space. The high end is a kitchen or family room with a full basement under it, a structural opening into the old house and plumbing.

What moves a rear addition up or down that range:

- Foundation type: a full basement means deeper digging and more concrete than a crawl space or slab.
- The opening into the existing house: a wide opening in a bearing wall needs a beam and posts down to footings.
- Plumbing: a kitchen or bathroom in the addition costs more than a bedroom or family room.
- Access: a narrow side yard means hand-digging or smaller machines.
- Conservation authority land: in a CLOCA-regulated area, a minor addition needs a CLOCA Minor Permit B at $535, and a standard permit starts at $1,990 ([CLOCA 2026 fee schedule](https://www.cloca.com/_files/ugd/6cdd05_ca1ea5bbdaa34f3ca770f69ab8f830e4.pdf)).

## What does a side addition cost?

We don't give a set range for side additions. Price a side addition like a rear addition of the same size, then check the side yard first, because it decides whether you can build at all.

In Whitby's older R1 to R3 zones, [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) requires an interior side yard of at least 1.5 m, as of October 2026. Since November 2025, an [Ontario regulation](https://www.ontario.ca/laws/regulation/060545) (O. Reg. 545/06, s.1.1) treats urban residential setbacks as 90% of the by-law figure, except near shorelines, valleys, wetlands, railways and in the Greenbelt, so ask the building department what yard it will actually apply. On a narrow lot that can leave very little room, and a side addition that crowds the line goes to the Committee of Adjustment for a minor variance. Whitby charges $1,526 for a residential variance in 2026, so it's worth knowing before you draw.

## What does a garage addition cost in Ontario?

We don't give a set range for a garage addition. A garage's price depends on a handful of choices you can price one at a time:

- Attached or detached. An attached garage ties into the house wall, roof and fire separation; a detached one needs its own footings on all sides.
- Heated and insulated, or not.
- Living space above. A room over the garage is priced like an addition, not like a garage.
- Driveway work, and a curb cut if the driveway widens.
- Whether it's later meant to become a garden suite. That brings in servicing, ADU zoning limits and a separate permit path; see our [guide to Bill 23 additional units](https://www.jarviscontracting.ca/guides/bill-23-additional-units-ontario).

The town's permit fee is the one number we can give you. Durham towns charge garages at a lower rate than living space:

| Town | 2026 garage permit fee | 500 sq ft garage (calculated) | Source |
|---|---|---|---|
| Whitby | $10.65/m2, garages, carport, porch, accessory structure | $495 | [Schedule N, line BGP-15](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) |
| Oshawa | $4.70/m2, attached garage (house) | $219 | [By-law 33-2009, item 33](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) |
| Ajax | $216 flat, detached carport or garage of 20 m2 or more | $216 | [Schedule A, item B11](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf) |
| Clarington | $5.88/m2, detached or attached garage | $273 | [By-law 2024-006](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington) |

Note: these are building permit fees only, calculated for 46.5 m2 from the 2026 schedules; they aren't construction costs, and we didn't confirm Pickering's garage line.

## What do Durham towns charge for an addition permit?

Durham towns charge the permit per square metre of new floor area, at $14.22 to $22.37 depending on the town, as of October 2026. To convert, 1 sq ft is 0.0929 m2, so 500 sq ft is about 46.5 m2.

Here are the 2026 permit fees for three common addition sizes:

| Town | Rate | 500 sq ft | 800 sq ft | 1,000 sq ft |
|---|---|---|---|---|
| Whitby | $22.37/m2 | $1,039 | $1,663 | $2,078 |
| Pickering | $20.12/m2 (new-house rate) | $936 | $1,495 + $2,379 deposit | $1,869 + $2,379 deposit |
| Clarington | $17.73/m2 | $824 | $1,318 | $1,647 |
| Oshawa | $15.56/m2 | $723 | $1,156 | $1,446 |
| Ajax | $14.22 per unit of floor area | $661 | $1,057 | $1,321 |

Note: calculated from each town's 2026 schedule ([Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf), [Oshawa](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf), [Ajax](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf), [Pickering](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING), [Clarington](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington)); Pickering prints no addition line, so its row uses the new-house rate, and Ajax doesn't print the unit.

A few rules change the bill. Pickering's schedule lists a $2,379 performance deposit for additions over 60 m2 and a newer $1,000 deposit line that also names additions; both are refundable, so ask the City which one applies to your permit. Clarington's fees rise 3% every 1 January under By-law 2024-006, so a permit applied for in 2027 costs more. And starting early costs extra everywhere: Whitby charges the greater of $100 or 25% of the fee if work starts before you apply, while Oshawa and Clarington add 25% if work began after applying and 50% with no application at all.

## Do home additions pay development charges in Durham?

No. An addition that only enlarges your existing home doesn't trigger development charges, under section 2(3) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27), as of October 2026. That's a big number to avoid: a new single detached house in Durham pays the Region alone $76,227 from 1 July 2026, per [Durham Region's development charge sheet](https://media-003-ca.cdn.govstack.com/durham-ca/media/vybhyyp2/durham-region-wide-development-charge-information-jul-1-2026.pdf), before the town and school board charges.

The answer changes if the addition holds a separate dwelling unit. A second or third unit inside the 3-unit provincial limits is also exempt, but in Whitby education development charges still apply to detached ADUs, per the [Town of Whitby's ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/). Tell the building department what the space is for before you apply.

## What does a full addition budget look like?

Add the pieces in this order: construction from a real quote, then permit drawings, then the town's permit from the table above, then any variance or conservation authority fee, then 13% HST. Our permit drawings for an addition are $6,000 to $12,000. That's drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are on top, so keep a reserve for the unforeseen.

For a 500 sq ft rear addition in Whitby, the costs outside construction are the drawings and the $1,039 permit, before a variance or a CLOCA permit. Construction is the part that swings, from $180,000 to $450,000 across our rear-addition range, which is why the scope matters more than the town.

If the addition is part of a bigger question about staying or selling, our guide on [whether to add on or move](https://www.jarviscontracting.ca/guides/renovate-or-move) puts land transfer tax and selling costs next to these numbers. If you're torn between a rear addition and going up, read [is it cheaper to build up or out](https://www.jarviscontracting.ca/guides/build-up-or-out).

## How we price additions at Jarvis

We're a family design-build firm in Ajax. Ceara Jarvis leads design through her studio, Juliette Interiors, and James Jarvis runs the build. Our contracts are fixed price. James prices the whole job and the contract is signed, with a 10% deposit, before design begins. Then we draw the permit set ourselves, so the foundation, the opening into the house and the finish level are drawn to that price. Any change goes through a change order you sign. The ranges on this page are ours for 2026; your price comes after James sees the house, and the first estimate is free.

The nearest finished addition we can show is [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), in east Toronto, roughly 40 km west of Whitby: a rear extension plus a new top storey, with the basement enlarged by removing a brick wall and full interior design, done in 10 months including design, permits and construction. For Durham projects, start at our [home additions page](https://www.jarviscontracting.ca/home-additions).

## Questions

### How much does a home addition cost in Ontario in 2026?

We price a home addition in Ontario at $350 to $600 per square foot in 2026, before HST. A single-storey rear addition of 300 to 700 sq ft runs $180,000 to $450,000 in our range. These are ranges, not quotes: your price comes after James sees the house, and the first estimate is free.

### Do I pay development charges on a home addition in Durham Region?

No development charges apply to a home addition in Durham Region if it only enlarges your existing home, under section 2(3) of the Development Charges Act as of October 2026. If the addition creates a separate dwelling unit, different rules apply, and Whitby still charges education development charges on detached ADUs.

### How much is a building permit for a home addition in Whitby?

A building permit for a home addition in Whitby costs $22.37 per square metre of new floor area in 2026, with a $305 minimum. That works out to $1,039 for 500 sq ft and $2,078 for 1,000 sq ft, calculated from Schedule N to By-law 7220-17.

### How much does a garage addition cost in Ontario?

We don't give a set range for a garage addition in Ontario, because the cost depends on whether it's attached, heated, or has a room above it. The permit is small: in Whitby, garages are $10.65 per square metre in 2026, about $495 for 500 sq ft.

### Is a small addition cheaper per square foot than a big one?

No, a small addition usually costs more per square foot than a big one, because the foundation, roof tie-in, drawings and permit cost about the same either way. That's why our 2026 range for a 100 to 300 sq ft bump-out still starts at $60,000 before HST.

### Do I need a minor variance for an addition in Durham?

You need a minor variance for an addition in Durham only if the plan breaks a zoning rule, such as a side yard, rear yard, height or lot coverage limit. Variance fees in 2026 run from $856 per lot in Oshawa to $2,500 in Pickering, and the building permit usually waits until the variance decision is final.

# How much does a second-storey addition cost in Ontario in 2026?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

We price a second-storey addition of 600 to 1,200 sq ft at $300,000 to $800,000 before HST in 2026. Work on the floor below, such as a new kitchen or bathrooms, adds to that. It's our range, not your quote: your price comes after James sees the house, and the first estimate is free. Below is what moves a job within the range, what quotes leave out, and what Durham Region, Ontario towns charge for the permit.

## Key takeaways

- Our 2026 range for a second storey of 600 to 1,200 sq ft is $300,000 to $800,000 before HST, and work on the floor below, such as a kitchen or bathrooms, adds to it.
- Our permit drawings for an addition are $6,000 to $12,000. That's drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra.
- In Whitby the building permit for an 800 sq ft second storey works out to $1,663, calculated from the [Town of Whitby's 2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) at $22.37 per square metre.
- A storey that only makes your house bigger pays no development charges, because the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27) excludes "the enlargement of an existing residential unit" (as of October 2026).
- Our [Greenwood](https://www.jarviscontracting.ca/projects/greenwood) job in Toronto, a rear extension plus a new top storey, took 10 months including design, permits and construction.

## What does a second storey cost in Ontario?

We price a second storey of 600 to 1,200 sq ft at $300,000 to $800,000 before 13% HST, as of October 2026. This page gives the whole-floor range, not a rate per square foot, because size is only one of the things that set the price.

Here are our 2026 ranges for a second storey and the work that often comes with it:

| Work | Our 2026 range, before HST |
|---|---|
| Second-storey addition, 600 to 1,200 sq ft | $300,000 to $800,000 |
| Kitchen renovation on the floor below, mid-range | $40,000 to $75,000, on top of the storey |
| Permit drawings for an addition | $6,000 to $12,000, drawings only |

Note: these are our ranges, not a quote; your price comes after James sees the house, and the first estimate is free. Drawing prices leave out permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen.

Where a job lands in the range comes down to the finish level, how much of the main floor gets reworked, and what the old house hides once the roof comes off. Builders' prices for the same storey can sit far apart for the same reason, so compare what each one includes before you compare the totals.

## What do second-storey quotes leave out?

The biggest gap is usually the floor you already live on. One RedFlagDeals poster got a $280,000 quote for a storey on a 1,300 sq ft bungalow, then found it left out the main floor; he reckoned the real figure was $400,000 to $450,000 ([RedFlagDeals thread](https://forums.redflagdeals.com/adding-storey-real-costs-1975637/)). That's one owner's estimate, but the pattern is common.

Going up touches the floor below in four places. The new stair takes a slice out of a main-floor room. Bearing walls and new point loads need beams and posts carried down to footings. Plumbing stacks and ductwork have to run up through finished rooms. And once the roof comes off, ceilings below often get patched or replaced.

Before you compare two second-storey quotes, check each one for these lines:

- An engineering review of the foundation and framing.
- Permit drawings. Ours for an addition are $6,000 to $12,000, and that's drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are on top.
- A reserve for anything unforeseen once the roof comes off and the walls open.
- Main-floor work: the stair opening, beams, ceiling repair, and moving the furnace or upsizing it.
- Rent if you move out, and 13% HST on the contract.

A quote that looks much cheaper than the next one often isn't. It just stops at the top of the new subfloor.

## What do permits and fees add in Durham Region?

Municipal fees are small next to construction, but they vary by town and they're easy to calculate yourself. Durham towns charge the building permit by square metre of new floor area, and an 800 sq ft storey is about 74.3 m2.

Here is the permit for an 800 sq ft second storey in each town, with the minor variance fee if your plan needs one:

| Town | 2026 rate for new floor area | Permit for 800 sq ft (calculated) | Minor variance fee, if needed |
|---|---|---|---|
| Whitby | $22.37/m2 ([Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)) | $1,663 | [$1,526](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf), plus CLOCA's $930 where CLOCA regulates the lot |
| Oshawa | $15.56/m2 ([By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf)) | $1,156 | [$856 per lot](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/) |
| Ajax | $14.22 per unit of floor area ([Schedule A](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf)) | $1,057 | [$1,638.90](https://ajax.ca/wp-content/uploads/2026/03/By-law-61-2024-2025-User-Fees-By-law.pdf) (2025 rate) |
| Pickering | $20.12/m2 new-house rate; no addition line ([2026 user fees](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING)) | about $1,495 at that rate, plus a refundable $2,379 performance deposit for additions over 60 m2 | $2,500 from 1 July 2026 |
| Clarington | $17.73/m2 ([By-law 2024-006](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington)) | $1,318 | [$2,280](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=455554&dbid=0&repo=Clarington) |

Note: permit figures are calculated from each town's 2026 schedule for 74.3 m2 and aren't quotes from the towns; Ajax doesn't print the unit, Pickering prints no addition line, and its schedule also has a $1,000 deposit line for additions, so ask the City which deposit applies.

A variance is where the time goes. Older Whitby R1 to R3 zones cap height at 8.5 m, and a second storey on a raised bungalow can bump into that. Our guide on [whether to build up or out](https://www.jarviscontracting.ca/guides/build-up-or-out) sets out the height and lot coverage limits town by town.

Development charges don't apply. Section 2(3) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27) says a permit whose only effect is to enlarge an existing home doesn't trigger them. That changes if the new floor holds a separate unit, so ask the building department before you draw a kitchen upstairs.

## How long does a second-storey addition take?

Plan on most of a year from first drawing to moving back into a finished house. Our [Greenwood](https://www.jarviscontracting.ca/projects/greenwood) job, a rear extension plus a new top storey, took 10 months including design, permits and construction. A minor variance adds time on top, because the building permit usually waits until the Committee of Adjustment's decision is final.

Under the Ontario Building Code, a town has 10 business days to decide a permit for a house where no unit sits above another, counted from a complete application ([2024 Building Code Compendium](https://www.publications.gov.on.ca/301880)). The clock doesn't start until the application is complete, and record volumes slow some towns down. Oshawa's permit page says "we cannot guarantee review timeframes will be met" ([Oshawa's building permit page](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/)).

Most families move out for at least part of the job. The roof comes off, the stair goes in through the main floor, and one Houzz reply put it bluntly: "your whole house will be a mess" ([Houzz discussion](https://www.houzz.com/discussions/6116203/staying-during-a-second-floor-addition)). Price rent into the comparison, especially if you're weighing the storey against selling. Our [add on or move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) runs those numbers.

## Can a second storey get HST relief?

Possibly, but not on its own. The CRA's owner-built rebate list covers owners who renovated the existing house and built a major addition, and its example is "a full second story to an existing bungalow" ([CRA new housing rebate page](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). So a full second storey that at least doubles the living space, together with a renovation of the existing house, can count for the owner-built rebates. A sunroom, family room or bedroom addition by itself doesn't.

The rules, dates and value caps are in our [HST relief guide](https://www.jarviscontracting.ca/guides/ontario-hst-relief-substantial-renovation). Confirm with the CRA before you count any rebate in the budget.

## How we approach second storeys at Jarvis

We're a family design-build firm based in Ajax. Ceara Jarvis designs through her studio, Juliette Interiors, and James Jarvis runs construction. Because one team prices, draws and builds the job, the stair, the beams and the main-floor work are in the price from the start, so the quote you see covers the house you'll live in, not just the new floor. Our contracts are fixed price: the whole project is priced and the contract signed, with a 10% deposit, before design begins, and any change goes through a change order you sign.

The closest finished example is [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), in east Toronto, roughly 30 km west of our Ajax office. It was a rear extension plus a new top storey with a primary suite, a wet room with a skylight and a den with a walkout balcony, the basement enlarged by removing a brick wall, and full interior design. It took 10 months, including design, permits and construction.

If you're pricing a second floor in Durham, start with our [second-storey additions page](https://www.jarviscontracting.ca/second-storey-additions) or read how [design-build](https://www.jarviscontracting.ca/design-build) handles drawings and pricing together.

## Questions

### How much does a second storey on a bungalow cost in Ontario?

We price a second storey of 600 to 1,200 sq ft on an Ontario bungalow at $300,000 to $800,000 before HST in 2026. Work on the main floor below, such as a new kitchen or bathrooms, adds to that.

That's our range, not a quote. Your price comes after James sees the house, and the first estimate is free.

### Why do second-storey addition prices vary so much?

Second-storey prices vary because each builder counts different things. Some ranges include design, engineering, permits and main-floor work; others stop at the new floor. Finish level and the state of the existing house matter too, which is why our own range for 600 to 1,200 sq ft runs from $300,000 to $800,000 before HST.

### Do I pay development charges on a second-storey addition in Ontario?

No, not if the second storey only enlarges your existing home. The Development Charges Act excludes work whose only effect is to enlarge an existing residential unit, as of October 2026. If the new floor creates a separate dwelling unit, different rules apply, so confirm with your town's building department.

### What does a building permit for a second storey cost in Durham Region?

A building permit for an 800 sq ft second storey costs about $1,057 in Ajax, $1,156 in Oshawa, $1,318 in Clarington and $1,663 in Whitby, calculated from each town's 2026 fee schedule. Pickering prints no addition line; at its new-house rate the fee would be about $1,495, plus a refundable performance deposit of $2,379 (the schedule also lists a $1,000 deposit for additions, so ask the City which applies).

### Can we live at home during a second-storey addition?

Living at home during a second-storey addition is hard for most families, because the roof comes off and the new stair cuts into the main floor. Many move out for at least part of the build. Our Greenwood job took 10 months including design and permits, so budget rent for the construction part of that time.

### Can my house hold a second storey?

Whether a house can hold a second storey depends on its foundation, its framing and the zoning height limit. An engineer checks the first two, and that study comes before design. The town's zoning by-law sets the height, which is 8.5 m in Whitby's older R1 to R3 zones as of October 2026.

# Is it cheaper to build up or out? 2026 Ontario costs

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

Neither is cheaper every time. We price a second storey of 600 to 1,200 sq ft at $300,000 to $800,000 before HST in 2026. A single-storey rear addition of 300 to 700 sq ft is $180,000 to $450,000, so the two ranges overlap. What tips it is your lot and your foundation, and in Durham Region, Ontario, the zoning limits on height and lot coverage, as of October 2026.

## Key takeaways

- We price a second storey of 600 to 1,200 sq ft at $300,000 to $800,000 before HST in 2026, and a single-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000.
- Small additions cost the most per foot: our 2026 range for a 100 to 300 sq ft bump-out still starts at $60,000. Drawings, a permit and a foundation cost about the same at any size.
- Whitby's older R1 to R3 zones cap lot coverage at 20% and require a 6.0 m rear yard under Schedule A of [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf), which often rules out building far back.
- Height limits in common older Durham zones run from 8.5 m in Whitby to 11.0 m in Ajax, per each town's zoning by-law, such as [Ajax's Section 6 zone table](https://ajax.ca/wp-content/uploads/2026/04/6-Section-6-Zone-Provisions_2026-March-Consolidation-Final.pdf).
- The CRA's example of a major addition for its owner-built HST rebates is "a full second story to an existing bungalow" ([CRA new housing rebate page](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). That can tilt the tax picture toward going up.

## Is it cheaper to build up or out in Ontario?

On price alone, our ranges for the two overlap too much to call. On total cost, it depends on how much space you need. Going out is usually the better deal for a modest room on a lot with space behind the house. Going up is usually the better deal when you need a whole floor of bedrooms and the lot has no room left.

Size is the hidden variable. Every addition carries fixed costs that barely change with its size: drawings, a permit, an engineer, getting crews and machines to site, tying the new roof or floor into the old house. Spread over a 100 to 300 sq ft bump-out, those costs are why our range for one starts at $60,000. Spread over a full floor, they weigh far less on each square foot. That's why a second storey can be cheaper per foot than a small rear addition, even though it's the bigger, harder job.

So the useful comparison isn't up versus out at the same size. It's the right-sized version of each. A family room off the kitchen and a three-bedroom floor upstairs aren't competing for the same job.

## What does each option pay for that the other doesn't?

Each direction carries costs the other skips, and they're the lines that end up deciding most jobs.

Here is where the money goes in each case:

| Cost driver | Building up | Building out |
|---|---|---|
| Foundation | uses the existing one, if it can carry the load; may need footings under new posts | new footings and walls, with a crawl space, slab or full basement |
| Engineering check | foundation and framing review by an engineer | soils and footing design, usually simpler |
| Roof | old roof comes off and a new one goes on top | old roof stays; new roof ties into it |
| Main floor | loses space to a new stair; plumbing and ducts run up through it | loses a wall or window where the opening goes |
| Lot space | none used | eats into yard and lot coverage |
| Living at home | hard while the roof is off | often possible until the tie-in |
| Conservation authority | rarely triggered | a CLOCA or TRCA permit if the footprint grows into a regulated area |

Note: this is a list of what each option pays for, not a price list; your drawings decide the figures.

Two lines carry most of the risk. Going up, it's the foundation: if the engineer finds the footings can't take a second floor, the cost jumps, which is why the study comes first. Going out, it's the lot: if zoning or a conservation authority says no to the footprint, the plan stops at a variance hearing or doesn't happen.

## What do Durham zoning limits allow in each direction?

Zoning decides a lot of up-or-out questions before cost does. Height limits cap how far up you can go, and lot coverage and yard setbacks cap how far out.

Here are the limits in the common older residential zones of each Durham town, as of October 2026:

| Town | Zone | Maximum height | Maximum lot coverage | Minor variance fee |
|---|---|---|---|---|
| Whitby | R1 to R3, By-law 1784 | 8.5 m | 20% | [$1,526](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) |
| Oshawa | R1-A to R1-E, By-law 60-94 | 9.0 m | 40% (45% with an accessory apartment) | [$856 per lot](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/) |
| Ajax | R1 and R2, By-law 95-2003 | 11.0 m | 30% (R1-A), 33% (R1-B), 45% (R1-C to R1-F); 45% on any lot with an accessory unit | [$1,638.90](https://ajax.ca/wp-content/uploads/2026/03/By-law-61-2024-2025-User-Fees-By-law.pdf) (2025 rate) |
| Pickering | R1D and R1E, By-law 8149/24 | 9.0 m | 33% | [$2,500](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING) from 1 July 2026 |
| Clarington | R1, By-law 84-63 | 10.5 m | 40%; 25% to 35% in Bowmanville's Neighbourhood Character Overlay | [$2,280](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=455554&dbid=0&repo=Clarington) |

Note: limits are from each zoning by-law ([Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf), [Oshawa](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf), [Ajax](https://ajax.ca/wp-content/uploads/2026/04/6-Section-6-Zone-Provisions_2026-March-Consolidation-Final.pdf), [Pickering](https://corporate.pickering.ca/WebLink/DocView.aspx?id=258309&dbid=1&repo=PICKERING), [Clarington](https://media-003-ca.cdn.govstack.com/clarington-018-ca/media/hq0jc0up/zoning-by-law-84-63-aoda.pdf)) for the zones named, and variance fees from each town's fee schedule; many newer subdivisions have their own zones with different numbers, so check yours.

Whitby is the town where this bites hardest. A 20% coverage cap is tight: on an 835 m2 lot, the smallest serviced interior lot the R3 zone allows, it leaves 167 m2, about 1,800 sq ft, of building footprint (calculated). A bungalow already near that line has little room to go out without a variance. The same zones cap height at 8.5 m, which can pinch a raised bungalow or a steep roof.

Setbacks moved a little in late 2025. Since 21 November 2025, [O. Reg. 545/06](https://www.ontario.ca/laws/regulation/060545) treats urban residential setbacks as 90% of the by-law figure, outside shorelines, valleys, wetlands, railways and the Greenbelt. On Whitby's 6.0 m rear yard, that's 5.4 m (calculated). Ask the building department how it applies to your lot before you rely on it.

Conservation authorities matter more for going out, because they regulate new or larger footprints near valleys, streams and the shoreline. In Whitby, Oshawa and parts of Clarington that's CLOCA, where a Minor Permit B for a minor addition costs $535 and a standard permit starts at $1,990 ([CLOCA's 2026 fee schedule](https://www.cloca.com/_files/ugd/6cdd05_ca1ea5bbdaa34f3ca770f69ab8f830e4.pdf)). Ajax and Pickering fall mostly under TRCA, with CLOCA covering parts of each. A variance in Whitby on CLOCA-regulated land also carries CLOCA's $930 processing fee.

## What about building down instead?

Building down means lowering the basement floor so it's full-height living space. It's the third option when the lot is full and the height limit is close. It isn't cheap: we price underpinning the full perimeter at $60,000 to $120,000 before HST in 2026. That buys height, not footprint, and the space is below grade. Our guide on [legal basement apartment costs](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) covers what it takes to finish it as a unit.

## Does going up or out change the HST picture?

It can, but size is what counts, not direction. The CRA's owner-built rebates can apply when you renovate the existing house and build a major addition, and its example is "a full second story to an existing bungalow" ([CRA new housing rebate page](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). An addition that at least doubles the living space, together with a renovation of the existing house, may qualify. A sunroom, family room or bedroom addition by itself doesn't. In practice, that favours the full second storey. See the [HST relief guide](https://www.jarviscontracting.ca/guides/ontario-hst-relief-substantial-renovation) and confirm with the CRA before you count on it.

## How we decide between up and out at Jarvis

We start with the lot and the foundation, not the wish list. Ceara Jarvis designs through her studio, Juliette Interiors, James Jarvis runs construction, and we draw the permit set in-house, so we can weigh both directions against your zoning and price the one that fits. The ranges on this page are ours for 2026; your price comes after James sees the house and the lot, and the first estimate is free.

Sometimes the answer is both. Our [Greenwood](https://www.jarviscontracting.ca/projects/greenwood) project in east Toronto, roughly 30 km west of our Ajax office, paired a rear extension with a new top storey holding a primary suite, a wet room with a skylight and a den with a walkout balcony, and enlarged the basement by removing a brick wall. It took 10 months, including design, permits and construction.

For the cost detail behind each direction, read [what a second-storey addition costs](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario) and [what a home addition costs](https://www.jarviscontracting.ca/guides/home-addition-cost-ontario). If you're also weighing a move, see [add on or move](https://www.jarviscontracting.ca/guides/renovate-or-move). Our [home additions](https://www.jarviscontracting.ca/home-additions) and [second-storey additions](https://www.jarviscontracting.ca/second-storey-additions) pages show how we work in Durham.

## Questions

### Is it cheaper to build up or out in Ontario?

Whether it's cheaper to build up or out in Ontario depends on how much space you need and what your lot allows. Our 2026 ranges overlap: $300,000 to $800,000 for a 600 to 1,200 sq ft second storey against $180,000 to $450,000 for a 300 to 700 sq ft rear addition, before HST. Small additions cost the most per foot, so a modest room favours going out and a full floor of bedrooms often favours going up.

### Does a second storey need a new foundation?

A second storey doesn't always need a new foundation, but the existing one has to carry the extra load, and only an engineer can say whether it will. If the footings fall short, they need work before anything goes up, so the study comes before design.

### How much of my lot can I cover in Whitby?

In Whitby's older R1, R2 and R3 zones, buildings can cover up to 20% of the lot under Schedule A of Zoning By-law 1784, as of October 2026. Many newer Whitby subdivisions have their own zones with different limits, so check the zoning map for your address before you plan to build out.

### How tall can a house be in Durham Region?

A house in the common older residential zones of Durham Region can be 8.5 m tall in Whitby, 9.0 m in Oshawa and Pickering, 10.5 m in Clarington and 11.0 m in Ajax, as of October 2026. Newer zones often differ, and going over the limit needs a minor variance from the Committee of Adjustment.

### Can we stay in the house while building out?

Staying in the house is usually easier with a ground-floor addition than with a second storey, because the old roof stays on and the main house stays closed until the opening is cut. With a second storey the roof comes off, so most families move out for part of the job.

### Is a small bump-out worth it compared with a bigger addition?

A small bump-out costs more per square foot than a bigger addition, because drawings, permits and foundation work cost about the same either way. Our 2026 range for a 100 to 300 sq ft bump-out is $60,000 to $180,000 before HST. It can still be worth it when a few feet fix a cramped kitchen.

# Ontario HST relief for owner-built homes and big renovations, 2026

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-05.

If you build your own home or substantially renovate the one you live in, and construction starts between 1 April 2026 and 31 March 2027, Ontario's temporary HST relief can return up to $130,000, the full 13% HST, on a home worth up to $1.5 million ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html); [Ontario Ministry of Finance](https://www.ontario.ca/page/ontario-new-home-affordability-payment)). The catch is the test: a "substantial renovation" means at least 90% of the interior removed or replaced, and an ordinary addition doesn't count. This is the rule as of October 2026; the Canada Revenue Agency (CRA) decides each claim.

## Key takeaways

- The Ontario Enhanced New Housing Rebate returns up to $80,000, the full 8% provincial part of the HST, for owner-built homes and substantial renovations where construction begins between 1 April 2026 and 31 March 2027 and is substantially completed before 2030 ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)).
- The Ontario New Home Affordability Payment adds up to $50,000, the federal 5% portion, for anyone who gets the enhanced rebate, so the two together reach $130,000 ([Ontario](https://www.ontario.ca/page/ontario-new-home-affordability-payment)).
- A renovation qualifies only if "at least 90% of the interior of the existing house" is removed or replaced, counting livable areas only ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html); [RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html)).
- A full second storey that at least doubles the living space can count when it comes with a renovation of the existing house, but a sunroom, family room or bedroom addition on its own doesn't ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)).
- The home's fair market value when the work is substantially complete must be under $1,850,000, and full relief runs to $1.5 million ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)).
- The relief is a rebate of HST you actually paid, so on a renovation it's capped by the HST on your invoices, not by the $130,000 headline ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)).

## What is Ontario's 2026 to 2027 HST relief?

It's two pieces that stack. The first is the Ontario Enhanced New Housing Rebate, administered by the CRA, which raises the old Ontario new housing rebate (capped at $24,000 regardless of value, per the [CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)) to as much as $80,000. The second is the Ontario New Home Affordability Payment, paid by Ontario, which covers up to $50,000 of the federal 5% portion. Ontario's Ministry of Finance announced the package on 25 March 2026 and said the relief "would be available from April 1, 2026 to March 31, 2027" ([media briefing](https://news.ontario.ca/assets/files/20260325/2eefe6f1395d191fdd2d4192e7bc685f.pdf)).

You don't apply to Ontario separately. You claim on the CRA's owner-built forms, GST191 and RC7191-ON, and tick the consent that passes your claim to Ontario for the top-up ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html); [Ontario](https://www.ontario.ca/page/ontario-new-home-affordability-payment)).

The amount depends on what the home is worth when the work is substantially complete:

| Fair market value at substantial completion | Ontario enhanced rebate (8% part) | Ontario affordability payment (5% part) |
|---|---|---|
| Up to $1,000,000 | 100% of the 8% HST paid, up to $80,000 | Full relief, up to $50,000 |
| $1,000,000 to $1,500,000 | Flat $80,000 | Flat $50,000 |
| $1,500,000 to $1,850,000 | Partial rebate of the 8% paid | Partial relief |
| $1,850,000 or more | None | None |

Note: bands from [CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html) and [Ontario's ONHAP page](https://www.ontario.ca/page/ontario-new-home-affordability-payment) as of October 2026; both rebates are limited to the HST you actually paid, and the payment is reduced by any federal HST rebate you claim.

## Does my renovation count as a "substantial renovation"?

Only if you gut it. The CRA's test is that "at least 90% of the interior of the existing house must be removed or replaced" ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). Notice 346 spells out what's left out of that 90%: the foundation, external walls, interior supporting walls, floors, roof and staircases ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)). Everything else inside, the partitions, drywall, kitchen, bathrooms, wiring, plumbing and mechanical, has to go or be replaced.

Only livable space counts. The CRA's guide says the test covers "the main floor living areas and finished basements and attics", and not garages or crawl spaces ([RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html)). A new kitchen, two bathrooms and new floors is a big job, and it's nowhere near 90%.

Here's how common jobs line up against the CRA's wording:

| Project | Likely to qualify? | Why |
|---|---|---|
| Whole-house gut to the structure, new interior throughout | Yes, if at least 90% of the livable interior is removed or replaced | Meets the substantial renovation test |
| Full second storey on a bungalow, plus a renovation of the existing floor | Possibly | CRA lists "renovated ... your existing house and built ... a major addition", such as a second storey that at least doubles the living space |
| Rear addition (family room, bedroom, sunroom) only | No | "Adding a sun porch, sun room, family room, or bedroom by itself is not a major addition" |
| Kitchen and bathroom renovation | No | Far short of 90% of the interior |
| Basement apartment in an existing house | No, as a renovation | Not 90% of the house; look at the federal multigenerational credit instead |
| A house you build yourself on land you own | Yes, as owner-built | Owner-built homes are covered when construction begins in the window |

Note: our reading of the [CRA rebate page](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html) and [RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html) as of October 2026; the CRA decides each claim on its facts, so ask it or a tax adviser before you count on the money.

## Does a second-storey addition qualify?

Sometimes. The CRA's own example of a major addition is "a full second story to an existing bungalow", an addition "that at least doubles the living space", but its owner-builder list pairs that addition with a renovation of the existing house ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). RC4028 describes the result as work "so significant that the result is viewed as a newly built house" ([RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html)).

So a 1,100 sq ft bungalow that gets an 1,100 sq ft second floor, with the main floor opened up and redone, is the shape of job the CRA has in mind. A 400 sq ft bedroom over the garage isn't. If you're close to the line, the drawings and the area calculations matter, and so does keeping them. Our [second-storey cost guide](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario) covers what that size of job costs in Ontario in 2026.

## What are the dates, and what if construction runs late?

Construction has to begin between 1 April 2026 and 31 March 2027, and the house has to be substantially completed before 2030 ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)). Substantially completed means "generally 90% or more", the point where someone could reasonably live there ([RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html)). Notice 346 doesn't define the day construction "begins", so don't plan on a start date that depends on a technicality.

The tight date is the start. Before a gut renovation or a second storey can start, you need drawings and a building permit, and sometimes a minor variance from the Committee of Adjustment. The Ontario Building Code gives a town 10 business days to decide a permit for a house, but only once the application is complete ([2024 Building Code Compendium](https://www.publications.gov.on.ca/301880)). In Durham Region, Ontario, the City of Oshawa warns that, with record volumes, "we cannot guarantee review timeframes will be met" ([Oshawa's permit page](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/)), and Pickering says its minor variance process takes about three months including the appeal period ([Pickering's Committee of Adjustment page](https://www.pickering.ca/business-building-development/planning-and-development/committee-of-adjustment/)). If you're starting design in late 2026, that window is already short.

The CRA's general owner-built deadline is two years after the earlier of first occupancy or substantial completion ([RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html)).

## How much could I actually get back?

You get back HST you paid, so the size of the job sets the ceiling. Notice 346 says combined Ontario rebates "cannot exceed the lesser of $80,000 and the provincial part of the HST payable" ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)). On a renovation you pay HST on the contract and materials, not on land you already own.

Take a gut renovation billed at $500,000 before tax. The 8% provincial part is $40,000 and the 5% federal part is $25,000. If the house is worth under $1.5 million when it's done, the enhanced rebate could return the $40,000 and the affordability payment the $25,000, about $65,000 in all, less any federal rebate you also claim. That's our arithmetic from the published rules, not a CRA calculation.

Value matters in Durham. The CMHC average cost of a new single detached house in 2025 was $1,356,332 in Whitby and $1,199,432 in Clarington, per [Durham Region's 2025 building activity review](https://media-003-ca.cdn.govstack.com/durham-ca/media/vc5lqmuu/2026-info-54-2025-annual-building-activity-review.pdf). A gutted and rebuilt house worth something like that would sit in the $1 million to $1.5 million band, where the relief is still the HST you paid, up to the caps. Fair market value is set when the work is substantially complete, so get an appraisal or a realtor's opinion on file if you're near $1.5 million.

## Who is eligible, and what about the federal rebates?

You must be an individual building or substantially renovating for your own or a relation's primary place of residence ([CRA Notice 346](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html)). The CRA says someone who renovates a house to live in "is generally not a builder of that house for GST/HST purposes" ([RC4028](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4028/gst-hst-new-housing-rebate.html)).

Two federal rebates can sit alongside, and they reduce the Ontario payment. The first-time home buyers' rebate returns up to $50,000 of GST on new or substantially renovated homes up to $1 million, including owner-built homes where construction begins from 20 March 2025 and before 2031 ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/first-time-home-buyers-gst-hst-rebate/what-rebate.html)). The older federal owner-built rebate applies only below $450,000 in value ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)), so few GTA homes see it.

## What paperwork should I keep?

Keep every original invoice in your name. The CRA says you must keep them for six years and won't accept photocopies, credit card slips or estimates instead ([CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html)). Ask your contractor for invoices that show the HST and their HST number, and keep the permit, the drawings and dated photos of the gutted interior. Those photos are the cheapest evidence you'll ever have that 90% came out.

## Where we come in

We design and build second storeys, additions and whole-house renovations from our office in Ajax, and we draw the permit drawings in-house, so design and construction run on one schedule. That matters here, because the date construction begins is the gate. If you're weighing a gut renovation against a move, our [renovate or move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) puts the two side by side, and our [design-build page](https://www.jarviscontracting.ca/design-build) explains how we take a job from drawings to keys.

For a sense of scale and time, our [Greenwood project](https://www.jarviscontracting.ca/projects/greenwood) added a rear extension and a new top storey to a house in east Toronto, roughly 40 km west of Whitby, and took ten months including design, permits and construction. We can't tell you whether your project qualifies for the rebate: that's the CRA's call, and worth a conversation with your accountant before you sign.

## Questions

### Does Ontario's 2026 HST relief apply to renovations?

Ontario's 2026 to 2027 HST relief applies to a substantial renovation, where at least 90% of the livable interior is removed or replaced, and construction begins between 1 April 2026 and 31 March 2027. Ordinary renovations, like a new kitchen and bathrooms, don't qualify.

### How much is the Ontario HST rebate on a substantial renovation?

The Ontario Enhanced New Housing Rebate returns up to $80,000 of the 8% provincial HST, and the Ontario New Home Affordability Payment adds up to $50,000 of the 5% federal portion, for up to $130,000 in total. On a renovation the refund can't exceed the HST you actually paid on the work.

### Does a second-storey addition qualify for the HST rebate in Ontario?

A full second storey that at least doubles the living space can qualify when it comes with a renovation of the existing house, according to the CRA. A smaller addition, or a family room, sunroom or bedroom added on its own, doesn't count as a major addition.

### What is the deadline for the Ontario enhanced HST rebate for owner-built homes?

For owner-built homes and substantial renovations, construction must begin on or after 1 April 2026 and on or before 31 March 2027, and the home must be substantially completed before 2030. The CRA's general deadline to file an owner-built claim is two years after the earlier of first occupancy or substantial completion.

### Is there a home value limit on Ontario's HST relief?

Yes. Full relief applies to homes worth up to $1.5 million at substantial completion, a partial rebate applies between $1.5 million and $1.85 million, and homes worth $1.85 million or more get none of the enhanced relief.

### Do I apply to Ontario or the CRA for the new home affordability payment?

You claim through the CRA on the owner-built rebate forms, GST191 and RC7191-ON, and consent to share the claim with Ontario. Ontario says no separate application is needed for the affordability payment.

# Questions to ask a contractor in Ontario before you sign

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-05.

Before you sign with a renovation contractor in Ontario, ask who files the building permit, whether you need a Workplace Safety and Insurance Board (WSIB) clearance certificate, for proof of liability insurance, and for a written contract with a deposit of no more than 10%. As of October 2026, those checks come from the province's consumer guidance, WSIB policy and the Construction Act. The Act also requires you to hold back 10% of each payment until liens expire ([Ontario, your rights when starting home renovations](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs); [Construction Act s. 22(1)](https://www.ontario.ca/laws/statute/90c30)).

## Key takeaways

- Any home renovation contract worth more than $50 must be in writing in Ontario, and one signed in your home carries a 10 calendar-day cooling-off period, as of October 2026 ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Ontario recommends a deposit of no more than 10%, and the final price can't run more than 10% over the estimate unless you agree to new work or a new price ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- A WSIB clearance certificate lasts up to 90 days, and homeowners hiring a contractor only for exempt home renovation work don't need one ([WSIB clearance certificate policy](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction)).
- Only licensed electrical contractors may do electrical work in your home, and each has a 7-digit licence number you can check ([Electrical Safety Authority guidance](https://esasafe.com/compliance/finding-the-right-contractor/)).
- You hold back 10% of the value of work supplied, and a contractor's lien expires 60 days after the earlier of publication of substantial performance or the contract ending ([Construction Act ss. 22(1) and 31(2)](https://www.ontario.ca/laws/statute/90c30)).
- Ontario tells you to get at least 3 written estimates and at least 3 references, and to check them ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

## Who pulls the building permit, you or the contractor?

Legally it's you, but the contractor or designer usually files as your agent. Ontario says "It's your responsibility to get building permits" ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). The Building Code lets the owner or an authorized agent make the application (Div. C 1.3.1.3.(5), [2024 Building Code Compendium](https://www.publications.gov.on.ca/301880)).

So ask: who files, who pays the fee, and who books the inspections? A good answer names a person and a step. A contractor who suggests skipping the permit is handing you the risk. In Whitby, in Durham Region, Ontario, applications go through the Town's E-Portal at portal.whitby.ca ([Town of Whitby, building permits](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)), and starting work before you apply costs the greater of $100 or 25% of the application fee ([Whitby's 2026 Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)). Oshawa and Clarington add 25% to the permit fee if construction starts after you've applied but before the permit is issued, and 50% if it starts with no application at all ([Oshawa fee by-law](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf); [Clarington fee by-law](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington)).

## Do they have WSIB coverage, and do you need a clearance certificate?

People who own or run a construction business in Ontario must have WSIB coverage, with some exceptions ([WSIB coverage rules for construction](https://www.wsib.ca/en/businesses/registration-and-coverage/expanded-compulsory-coverage-construction-industry)). The exception that matters here is home renovation. An owner-operator doing only home renovation work directly for the person who lives in the house is exempt for themselves, but not for their workers or their subcontractors ([WSIB Policy 12-01-06](https://www.wsib.ca/en/operational-policy-manual/expanded-compulsory-coverage-construction)).

The clearance certificate is the other half. Under WSIB policy, a principal who directly hires a construction contractor must get a clearance certificate, which lasts up to 90 days. Homeowners hiring a contractor only for exempt home renovation work are excluded from that rule. Without one, a principal who needed it may be liable for the contractor's unpaid premiums up to the labour portion of the contract ([WSIB Policy 14-02-19](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction)).

Ask for the WSIB account and a current clearance certificate. If the contractor says the exemption covers them, ask who else will be on site. Their crew and their sub-trades should be covered either way. If you're not sure whether your job counts as exempt home renovation work, call WSIB before you sign.

## Do they carry liability insurance?

Ask for a certificate of insurance, not a verbal yes. We won't suggest a coverage amount, because we haven't found an Ontario rule that sets one for renovators. Read the certificate for the insurer, the policy number, the coverage limit and the expiry date. Then call the broker on it to confirm it's in force. Ontario's renovation rights page doesn't set an insurance rule, so this is a check you run yourself.

## Does the contractor need a licence?

Not for renovations. The Home Construction Regulatory Authority (HCRA) says "all new home builders and sellers" must be licensed, and that renovations to an existing home typically don't make it new ([HCRA licence page](https://www.hcraontario.ca/do-i-need-a-licence/)). It also says renovators "aren't licensed or regulated like new home builders" ([HCRA page on finding a renovator](https://www.hcraontario.ca/resources/finding-a-renovator/)). The exception: coach, laneway and tiny homes generally need licensing and warranty coverage, so a detached garden suite is a different question. Our [HCRA and Tarion guide](https://www.jarviscontracting.ca/guides/hcra-and-tarion-explained) covers it.

Trades are different. Ask who does the electrical and the gas work, by name:

- Electrical: only Licensed Electrical Contractors may do electrical work in your home, each has a 7-digit licence number from the Electrical Safety Authority (ESA) and the Electrical Contractor Registration Agency (ECRA), and a notification of work must be filed before work starts ([ESA guidance](https://esasafe.com/compliance/finding-the-right-contractor/)).
- Gas: gas work falls under O. Reg. 212/01, which calls for contractors registered with the Technical Standards and Safety Authority (TSSA) and certified gas technicians ([O. Reg. 212/01](https://www.ontario.ca/laws/regulation/010212)).

Here are the questions to ask, what a good answer sounds like, and where to check it:

| Question | A good answer | Where to check |
|---|---|---|
| Who files the permit and books inspections? | A named person, filing as your agent | Your town's permit portal; [Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) |
| Can I see your WSIB clearance certificate? | A current certificate, or a clear reason the exemption applies | [WSIB clearance policy](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction) |
| Can I see your certificate of insurance? | A current certificate you can confirm with the broker | The broker named on it |
| Who does the electrical, and what's their licence number? | A Licensed Electrical Contractor with a 7-digit number | [ESA guidance](https://esasafe.com/compliance/finding-the-right-contractor/) |
| Who does the gas work? | A TSSA-registered contractor | [O. Reg. 212/01](https://www.ontario.ca/laws/regulation/010212) |
| Can I speak to 3 past clients? | Names and numbers, with jobs like yours | Ontario's renovation rights page |
| Who's on site each day? | A named lead, and a list of sub-trades | The contract |

Note: This is a starting checklist, not a full vetting process; a good answer still has to match the paperwork.

## What should the contract say before you sign?

It must be in writing for anything over $50. Ontario says it should list the contractor's name, address and contact details. It should also give a thorough description of the work, any warranties, the total cost and payment terms, start and completion dates, the payment schedule and deposit, who cleans up, and all the sub-trades ([Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

The same page recommends no more than a 10% deposit, warns you to "avoid cash deals", and points you to the Consumer Beware List to look up complaints or charges. If you sign in your home, you have 10 calendar days to cancel for any reason without a fee. The final price can't run more than 10% over the estimate unless you agree to new work or a new price, so ask how changes get priced and signed. Our [fixed price vs cost-plus guide](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus) goes deeper on that.

## How will payments and the holdback work?

Ask for a payment schedule tied to stages you can see, and tell the contractor up front that you'll hold back 10%. Section 22(1) of the [Construction Act](https://www.ontario.ca/laws/statute/90c30) requires it. Section 24(1) lets you pay up to 90% safely unless you get written notice of a lien. Section 31(2) ends a contractor's lien rights 60 days after the earlier of publication of substantial performance or the contract being completed, abandoned or terminated.

The reason to care is in the news. In July 2026, the Toronto news channel CP24 reported a Brampton owner who paid $33,000, about 90% of the contract, for a basement apartment left unfinished. A poll by CTV News and the research firm Nanos in the same report found 26.7% of Canadians had experienced, or knew someone who had, unfinished renovation work after payment ([CP24, 9 July 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)). A forum reply on a similar story put it bluntly: "never pay more than 100 for deposit!" ([RedFlagDeals, 2020](https://forums.redflagdeals.com/contractor-took-deposit-didnt-show-2403023/)). That's stricter than the province, but the instinct is right.

Here are the numbers to have in front of you when you sign:

| Rule | Number | Source |
|---|---|---|
| Contract must be in writing | Over $50 | [Ontario's renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) |
| Recommended deposit | No more than 10% | Ontario's renovation rights page |
| Final price over the estimate | No more than 10% without agreed new work | Ontario's renovation rights page |
| Cooling-off, contract signed at home | 10 calendar days | Ontario's renovation rights page |
| Holdback | 10% of work supplied | [Construction Act s. 22(1)](https://www.ontario.ca/laws/statute/90c30) |
| Contractor's lien period | 60 days | Construction Act s. 31(2) |
| WSIB clearance certificate | Valid up to 90 days | [WSIB Policy 14-02-19](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction) |

Note: These are the rules as published in October 2026; they're not legal advice, and a lawyer should read the contract on a large job.

## How we work

We're a family design-build firm in Ajax. Ceara Jarvis leads design through her studio, Juliette Interiors, we draw permit drawings in-house, and James Jarvis runs construction, under one contract. Ask us every question on this page; we'd rather you check than assume. The steps are on our [design-build](https://www.jarviscontracting.ca/design-build) page, and the [design-build vs an architect plus a general contractor guide](https://www.jarviscontracting.ca/guides/design-build-vs-general-contractor) explains when the other route fits better. The nearest finished job with a full write-up is [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), a rear extension and new top storey in east Toronto, roughly 30 km west of our Ajax office. When you're ready, [get in touch](https://www.jarviscontracting.ca/contact).

## Questions

### Who is responsible for getting the building permit for a renovation in Ontario?

The homeowner is responsible for building permits in Ontario as of October 2026, according to the province's renovation rights guidance. The Building Code lets an authorized agent, such as your contractor or designer, file the application for you.

Agree in writing who files, who pays the fee and who books inspections. In Whitby, starting work before applying costs the greater of $100 or 25% of the application fee.

### Does my contractor need a WSIB clearance certificate for a home renovation?

Under WSIB policy, a principal who directly hires a construction contractor must get a clearance certificate, valid up to 90 days, but homeowners hiring a contractor only for exempt home renovation work are excluded. The exemption covers owner-operators working directly for the person who lives in the house, not their workers or subcontractors.

Ask the contractor for their WSIB account and clearance anyway, and call WSIB if you're unsure whether your job is exempt.

### Do renovation contractors need a licence in Ontario?

Renovation contractors in Ontario aren't licensed by the Home Construction Regulatory Authority, which licenses new home builders and sellers. Renovating an existing house typically doesn't make it a new home, though coach, laneway and tiny homes generally do need licensing.

Specific trades still need their own credentials: electrical work needs a Licensed Electrical Contractor, and gas work needs a TSSA-registered contractor.

### How much deposit should I give a contractor in Ontario?

Ontario recommends a renovation deposit of no more than 10% of the contract, as of October 2026, and warns against large down payments to cover materials. After the deposit, pay in stages tied to finished work.

Hold back 10% of each payment as the Construction Act requires, and release it once the lien period has passed.

### Can I cancel a renovation contract in Ontario after signing?

If you signed a home renovation contract worth $50 or more in your home, Ontario gives you a 10 calendar-day cooling-off period to cancel for any reason, without a cancellation fee. The right applies to contracts signed at home, as of October 2026.

Ontario's page ties the right to contracts signed in your home, so if you sign anywhere else, don't count on it and read the contract first.

### How many quotes should I get for a renovation in Ontario?

Ontario recommends at least 3 written estimates from different contractors for a home renovation, and at least 3 references you actually check. Comparing quotes is easier when every contractor prices the same drawings and scope.

Compare allowances, exclusions and payment schedules line by line, not just the total.

# Should we add on or move? Costs compared for 2026

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

Moving costs you money that buys no space: land transfer tax, commission, legal fees and the move itself. As of October 2026, buying a $1,200,000 house in Durham Region, Ontario means $20,475 in [Ontario land transfer tax](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax), and the same house in Toronto means $40,950, because the City adds its own tax. An addition skips those costs but carries its own: we price a second storey of 600 to 1,200 sq ft at $300,000 to $800,000 before HST in 2026.

## Key takeaways

- Ontario land transfer tax on a $1,000,000 purchase is $16,475, calculated from the [provincial rate table](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax), and Durham towns add no municipal tax on top as of October 2026.
- Toronto's [Municipal Land Transfer Tax](https://www.toronto.ca/services-payments/property-taxes-utilities/municipal-land-transfer-tax-mltt/municipal-land-transfer-tax-mltt-rates-and-fees/) uses the same brackets up to $2,000,000, so a Toronto buyer pays twice the Durham figure, $32,950 on a $1,000,000 home.
- Real estate commission is set by the brokerage and negotiable, not fixed by [RECO](https://www.reco.on.ca/home-buyers-sellers/selling-home/commissions-fees-charged-brokerage-2/) or government, so every 1% you agree to on a $1,000,000 sale costs $10,000 plus HST.
- We price a second storey of 600 to 1,200 sq ft at $300,000 to $800,000, and a single-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000, before HST in 2026.
- The average new single detached house in Whitby cost $1,356,332 in 2025, according to CMHC data in [Durham Region's 2025 building activity review](https://media-003-ca.cdn.govstack.com/durham-ca/media/vc5lqmuu/2026-info-54-2025-annual-building-activity-review.pdf); that's new builds, not resale.

## Is it cheaper to add on or move?

It's cheaper to add on when the space you need is less than the price gap to a bigger house plus what the move itself costs. That sounds obvious, but most people compare the wrong two numbers. They put the addition's full price against the move's transaction costs, and forget the move also needs a bigger, more expensive house at the other end.

Split moving into two piles. The first pile is the price difference between your house and the next one. That money buys space, the same as an addition does. The second pile is land transfer tax, commission, legal fees, a mortgage penalty if you break your term, and the movers. That money buys nothing you keep. An addition only has a first pile, plus a few town fees and possibly rent while you're out of the house.

So compare like with like: does the addition cost less than the price gap plus the second pile? If a bigger house nearby costs $300,000 more than yours and you'd lose $60,000 to the move, an addition that delivers the same space for under $360,000 wins. Those two inputs are yours to look up; the numbers in this guide fill in the rest.

## How much does it cost to move in Durham Region compared with Toronto?

Moving costs less in Durham than in Toronto, mainly because Toronto is the only Ontario city with its own land transfer tax. Whitby, Oshawa, Ajax, Pickering and Clarington buyers pay only the provincial tax, as of October 2026.

Here is the land transfer tax a buyer pays at four prices:

| Purchase price | Durham Region (provincial only) | Toronto (provincial plus municipal) |
|---|---|---|
| $800,000 | $12,475 | $24,950 |
| $1,000,000 | $16,475 | $32,950 |
| $1,200,000 | $20,475 | $40,950 |
| $1,500,000 | $26,475 | $52,950 |

Note: calculated from the [provincial brackets](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax) (0.5% to 2.5%) and Toronto's matching municipal brackets in force from 1 April 2026, for a single-family home; first-time buyers can get up to $4,000 of the provincial tax refunded ([first-time buyer refund](https://www.ontario.ca/document/land-transfer-tax/land-transfer-tax-refunds-first-time-homebuyers)).

The tax is only one line. Commission is the other big one, and there's no standard rate to print. [RECO's page on brokerage fees](https://www.reco.on.ca/home-buyers-sellers/selling-home/commissions-fees-charged-brokerage-2/) says neither RECO nor any government sets commission; it can be a percentage, a flat fee or both. Ask two or three brokerages for their rate, then multiply it by your likely sale price.

Legal fees, the mortgage penalty and the movers depend on your lender, your term and how far you're going. We couldn't find a credible 2025 or 2026 source for typical figures, so we don't print one. Your mortgage statement and one call to your lender will give you the penalty, and that's often the biggest of the three.

## What does each option pay for?

The two choices spend money on different things, and only some of it comes back as space.

Here is the side-by-side, line by line:

| Cost line | If you move | If you add on |
|---|---|---|
| Land transfer tax | $20,475 on a $1,200,000 Durham home; $40,950 in Toronto | none |
| Commission | your negotiated rate times the sale price, plus HST | none |
| Legal, penalty, movers | depends on your lender and distance | legal usually none; rent if you move out during the build |
| Space itself | the price gap to the bigger house | construction: a 600 to 1,200 sq ft second storey at $300,000 to $800,000 in our 2026 range |
| Town fees | none from the town | a Whitby permit of $1,663 for 800 sq ft; no development charges |
| Time | a closing date | most of a year; our [Greenwood](https://www.jarviscontracting.ca/projects/greenwood) job took 10 months including design, permits and construction |

Note: the addition figures are our 2026 ranges before HST, not a quote; the town fee is calculated from [Whitby's 2026 Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf), and the move figures exclude anything we couldn't source.

Two lines tilt the comparison in Durham. Additions that only enlarge your home pay no development charges under section 2(3) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27). And we price a one-storey rear addition of 300 to 700 sq ft at $180,000 to $450,000 in 2026, so going out can cost less than going up if the lot has room. The detail on both is in our guides to [home addition costs](https://www.jarviscontracting.ca/guides/home-addition-cost-ontario) and [second-storey costs](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario).

## When does moving make more sense?

Moving makes more sense when the house or the lot can't give you what you need at a sane price. Common reasons:

- The lot can't take it. Height limits, lot coverage, conservation authority hazard land or a heritage district can rule out the addition, or push it to a variance. Our [build up or out guide](https://www.jarviscontracting.ca/guides/build-up-or-out) lists the limits by town.
- The house needs a gut anyway. One RedFlagDeals reply in November 2025 put it this way: "Almost always easier to sell and move than to do a full gut renovation" ([RedFlagDeals thread](https://forums.redflagdeals.com/help-advice-wanted-renovating-possible-addition-bungalow-2790193/)).
- You need a different school, commute or neighbourhood. No addition fixes that.
- The budget is small. Another RedFlagDeals poster, tallying a move against a modest renovation in 2021, got the reply "$100k these days can't get you far." ([RedFlagDeals thread](https://forums.redflagdeals.com/calculating-cost-benefit-moving-vs-renovating-2480375/)).

Be honest about the disruption, too. A second storey usually means moving out for part of the build, so you pay rent and still deal with movers twice.

## When does adding on win?

Adding on wins when you like the street, the lot has room, and your mortgage is one you'd rather keep. It also wins when the bigger houses near you sell for much more than yours: the wider that price gap, the more an addition saves, because you're buying the space at construction cost instead of market price.

It helps to check the land before the house. A house on a deep lot with room behind it is an easier case than one already close to its zone's lot coverage cap, which is 20% in Whitby's older R1 to R3 zones. Your town's zoning map and by-law will tell you which you have.

There may also be a tax angle for a large project. The CRA says owner-built rebates can apply when you renovate the existing house and build a major addition, such as a full second storey that at least doubles the living space; a family room or bedroom addition by itself doesn't count. Our [HST relief guide](https://www.jarviscontracting.ca/guides/ontario-hst-relief-substantial-renovation) has the rules, and you should confirm with the CRA before counting on it.

## How we help with add-on-or-move decisions

We build additions for a living, so we're not neutral, and we'd rather you know that up front. What we can do is give you the addition side of the comparison in real numbers: Ceara Jarvis designs through Juliette Interiors, James Jarvis prices and builds, and we draw the permit set in-house, so the plan your town reviews is drawn to that price. Our contracts are fixed price, so the addition side is a signed number, and any change goes through a change order you sign. The ranges on this page are ours; your price comes after James sees the house, and the first estimate is free. You bring the move side from a brokerage and your lender.

The closest finished example we can show you is [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), in east Toronto, roughly 30 km west of our Ajax office. It added a rear extension and a new top storey with a primary suite, enlarged the basement by removing a brick wall, and took 10 months including design, permits and construction. See our [home additions](https://www.jarviscontracting.ca/home-additions) and [second-storey additions](https://www.jarviscontracting.ca/second-storey-additions) pages, or how [design-build](https://www.jarviscontracting.ca/design-build) keeps design and price in one place.

## Questions

### Is it cheaper to renovate or move in Ontario?

Whether renovating or moving is cheaper in Ontario depends on the price gap to a bigger house plus the transaction costs of moving, compared with the cost of the addition. Land transfer tax, commission, legal fees and the move buy no space, so they count only against moving. On the addition side, our 2026 range for a 600 to 1,200 sq ft second storey is $300,000 to $800,000 before HST.

### How much is land transfer tax on a $1,000,000 house in Durham Region?

Land transfer tax on a $1,000,000 house in Durham Region is $16,475, calculated from Ontario's provincial brackets as of October 2026. Durham towns charge no municipal land transfer tax, so that's the whole tax. First-time buyers can get up to $4,000 of it refunded.

### Do Whitby, Oshawa or Ajax charge a municipal land transfer tax?

No. Whitby, Oshawa, Ajax, Pickering and Clarington don't charge a municipal land transfer tax as of October 2026; Toronto is the only Ontario city that does. Buyers in Durham Region pay only the provincial tax.

### What is the typical real estate commission in Ontario?

There's no typical real estate commission set in Ontario. RECO says neither RECO nor any government fixes commission; the brokerage sets it, it's negotiable, and it can be a percentage, a flat fee or both. Get quotes from a few brokerages and multiply the rate by your expected sale price.

### How long does an addition take compared with moving?

An addition takes much longer than a move. Our Greenwood job, a rear extension plus a new top storey, took 10 months including design, permits and construction, and a minor variance adds time on top. A move takes as long as your closing dates, but costs you land transfer tax and commission that an addition doesn't.

### Is a second storey worth it compared with buying a bigger house?

A second storey is worth it compared with buying a bigger house when it costs less than the price difference plus the money lost to moving. We price a second storey of 600 to 1,200 sq ft at $300,000 to $800,000 before HST in 2026. Compare that with what larger homes on your street sell for, then add the land transfer tax and commission you'd avoid.

# What does a legal basement apartment cost in Ontario in 2026?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-13.

We price a full legal basement apartment in Ontario at $80,000 to $180,000 before HST in 2026, and legalising a basement that's already finished at $45,000 to $95,000. Your own price comes after James sees the basement, and the first estimate is free. In Durham Region, Ontario, the town's permit fee on a 700 sq ft unit adds $434 to $693 (our calculation), there are no development charges on the unit, and a federal tax credit can return up to $7,250 if the unit houses a senior or a disabled relative. All figures are as of October 2026.

## Key takeaways

- Our 2026 range is $80,000 to $180,000 for a full legal basement apartment and $45,000 to $95,000 to legalise one that's already finished, before HST.
- A separate entrance is often the cost that surprises owners: we price a separate side entrance at $18,000 to $28,000, and underpinning the full perimeter at $60,000 to $120,000.
- The permit fee for a 700 sq ft unit, calculated from the 2026 schedules, ranges from $434 in Clarington to $693 in Whitby ([Whitby's 2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)).
- A second or third unit inside an existing house pays no development charges under section 2(3.2) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27).
- The Multigenerational Home Renovation Tax Credit is 14.5% of up to $50,000 in costs, a maximum of $7,250, per the [CRA's MHRTC page](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc.html).

## What does a legal basement apartment cost in Ontario in 2026?

Our ranges are wide, and the biggest jumps come from the entrance and from lowering the floor. They're our own 2026 prices, before 13% HST.

Here are our 2026 ranges for a basement unit and the work that often goes with it:

| Item | Our 2026 range |
|---|---|
| Full legal basement apartment | $80,000 to $180,000 |
| Legalise an already finished basement | $45,000 to $95,000 |
| Basement finishing, not a separate unit | $55 to $90 per sq ft |
| Basement bathroom | $25,000 to $50,000; the top end is when new plumbing has to go under the slab |
| Separate side entrance | $18,000 to $28,000 |
| Underpinning, full perimeter | $60,000 to $120,000 |
| Permit drawings for a basement apartment | $4,000 to $8,000, drawings only |

Note: these are our ranges, not a quote; your price comes after James sees the basement, and the first estimate is free. Drawing prices leave out permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen.

## What pushes a basement apartment to the top of the range?

Three things move the number most: the entrance, the ceiling height and the work behind the drywall. The entrance and the egress windows are what tend to surprise owners, especially where the foundation wall has to be cut.

On the entrance, we price a separate side entrance at $18,000 to $28,000. A walk-up costs more, because you're digging a stairwell, building retaining walls and adding a drain at the bottom.

The ceiling height comes next, because the [2024 Ontario Building Code](https://www.publications.gov.on.ca/301880) sets 1.95 m for ceilings in a secondary suite and 1.85 m under beams and ducts (Div. B 9.5.3.1.). If your basement is lower, the floor has to come down. We price underpinning the full perimeter at $60,000 to $120,000.

Then the fire and life-safety work: Type X drywall on the ceiling and walls between the units, interconnected smoke alarms through the whole house, and an egress window in every bedroom level. None of it shows when you're done, and all of it gets inspected. Our [requirements guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario) lists each rule with its Code article.

## What do Durham towns charge in permit and registration fees?

Durham fees are small next to the build, but they vary by town and some towns add a deposit or a registration step. As of October 2026, here's the floor-area permit fee for a 700 sq ft (65.0 m2) unit, calculated from each town's 2026 schedule:

| Town | Permit fee, 700 sq ft unit (calculated) | Below-grade entrance fee | Registration |
|---|---|---|---|
| Whitby | $693 at $10.65/m2, "Residential (ADU) Alterations" ([Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)) | $305 flat | Required, $268 ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)) |
| Oshawa | No unit line; $507 at the $7.79/m2 basement-finish rate ([Oshawa fee by-law](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf)) | $160 walk-up stair | Two-unit house registration issued through the permit ([Oshawa accessory apartments page](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/)) |
| Ajax | $630 at $9.68, "Residential Accessory Dwelling Unit" ([Ajax 2026 fee schedule](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf)) | $329 | No current program found |
| Pickering | $479 at $7.37/m2, plus a $1,000 refundable performance deposit ([Pickering 2026 user fees](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING)) | $180 basement walkout | Mandatory under By-law 8040/23, fee not found ([Pickering ADU page](https://www.pickering.ca/business-building-development/building-and-renovating/additional-dwelling-units/)) |
| Clarington | $434 at $6.68/m2, "Apartment In-House" ([Clarington fee by-law](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington)) | Not found in the schedule | Not found |

Note: these are our calculations of the floor-area fee only; the town calculates the final permit fee, and Oshawa staff price a new unit case by case.

Whitby charges $534 to register a unit it finds through a complaint, instead of $268, so register on time. Whitby also reimburses the ADU permit fee, the registration inspection fee and the below-grade entrance fee through its Housing Accelerator Fund incentive, for complete applications made by 31 December 2026. Our [Whitby ADU incentive guide](https://www.jarviscontracting.ca/guides/whitby-adu-incentive) covers the deadlines. For the basement permit itself, town by town, see [basement permits in Durham Region](https://www.jarviscontracting.ca/guides/basement-permits-durham-region).

## Do you pay development charges on a basement apartment?

No. As of October 2026, a second or third unit inside an existing house, or one unit in a backyard building within the three-unit limit, pays no development charges under section 2(3.2) of the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27). For scale, a new single detached house in Whitby pays $136,784 in Region, education and Town charges combined (our sum of the [Durham Region July 2026 rates](https://media-003-ca.cdn.govstack.com/durham-ca/media/vybhyyp2/durham-region-wide-development-charge-information-jul-1-2026.pdf) and the Town and school board rates).

Whitby's [ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/) adds one wrinkle: education development charges still apply to a detached ADU in the backyard, and to a unit in a new house occupied for less than 12 months. A basement unit in a house you've lived in longer doesn't trigger them. Our [Bill 23 guide](https://www.jarviscontracting.ca/guides/bill-23-additional-units-ontario) explains how many units each town allows.

## Is there a tax credit for a basement apartment for a parent?

Yes, if the unit is for a senior or a disabled adult relative. The federal Multigenerational Home Renovation Tax Credit is 14.5% of up to $50,000 in qualifying costs, so a maximum of $7,250. It's refundable, per the [CRA's MHRTC page](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc.html) (updated 20 January 2026), which sets out the rules for the 2025 tax year.

The CRA's [eligibility page](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc/who-claim-mhrt.html) sets the conditions. The unit has to be self-contained, with a private entrance, kitchen, bathroom and sleeping area. It has to satisfy local permits, codes and by-laws, which is one more reason to build it legally. The person it's for must be 65 or older, or 18 to 64 and eligible for the disability tax credit. Only one renovation can be claimed for that person in their lifetime.

The [CRA's expenses page](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc/expenses-claim-mhrtc.html) excludes appliances, financing costs and work done by a relative who isn't registered for GST/HST. Permits and building plans count. Check the rules for the year you'll finish with the CRA before you count on the credit.

## How do you protect the money once you've signed?

Pay in stages and hold back what the law lets you hold back. Ontario [recommends](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) a deposit of no more than 10%, and the [Construction Act](https://www.ontario.ca/laws/statute/90c30) requires you to hold back 10% of the value of work as it's supplied until lien rights expire. This matters for basements in particular: in July 2026 [CP24 reported](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/) a Brampton owner who'd paid $33,000, about 90% of the contract, for a basement apartment left unfinished. Our guide to [HCRA and Tarion](https://www.jarviscontracting.ca/guides/hcra-and-tarion-explained) explains why renovators aren't licensed like new home builders.

## How we work on basement apartments

We're Jarvis Contracting, a family design-build firm based in Ajax. James Jarvis runs construction and his wife, Ceara Jarvis, runs design through her studio Juliette Interiors. We draw permit drawings in-house and build basements and additional units, so the entrance, the ceiling height and the fire separation are priced by the team that draws them for the town and builds them. Our contracts are fixed price, and any change goes through a change order you sign.

The ranges above are ours, but we don't quote a basement from a range, because the two biggest variables, the floor-to-joist height and where an entrance can go, can only be measured on site. Your price comes after James sees the basement, and the first estimate is free. Our one published project, [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), is in east Toronto, roughly 40 km west of Whitby. It's an addition with an enlarged basement, not a second unit. See our [basement renovations page](https://www.jarviscontracting.ca/basement-renovations) for how we run a basement job.

## Questions

### Is it cheaper to legalise a finished basement than to build a new basement apartment?

Legalising a finished basement is usually the cheaper route. We price legalising an already finished basement at $45,000 to $95,000 before HST in 2026, against $80,000 to $180,000 for a full legal basement apartment. The saving shrinks fast if the existing finish has to be opened up for fire separation, egress windows or a ceiling that's under the 1.95 m the Building Code sets for a secondary suite.

### How much does a separate entrance for a basement apartment cost?

We price a separate side entrance for a basement apartment at $18,000 to $28,000 before HST in 2026. A walk-up costs more, because it means digging a stairwell, building retaining walls and adding a drain at the bottom. Cutting the foundation wall is what makes any entrance expensive.

### Do I pay development charges on a basement apartment in Durham Region?

No. As of October 2026, the Development Charges Act exempts a second or third unit inside an existing house from development charges anywhere in Ontario, including Durham Region. Whitby still charges education development charges on a detached backyard unit, and on a unit in a house occupied for less than 12 months, but not on a basement apartment in an established house.

### Can I claim the Multigenerational Home Renovation Tax Credit for a basement apartment?

You can if the basement apartment is for a relative who is 65 or older, or an adult eligible for the disability tax credit. The credit is 14.5% of up to $50,000 in costs, a maximum of $7,250. The unit needs its own private entrance, kitchen, bathroom and sleeping area. The CRA allows one claim per qualifying person in their lifetime.

### How much is the building permit for a basement apartment in Whitby?

The Whitby building permit for a 700 sq ft basement apartment works out to about $693 at the 2026 rate of $10.65 per m2, by our calculation from Schedule N. A below-grade entrance adds a $305 flat fee and registration costs $268. Whitby's Housing Accelerator Fund incentive reimburses the permit and entrance fees for complete applications made by 31 December 2026.

# What does a legal basement apartment need in Ontario?

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-05.

A legal basement apartment in Ontario needs a building permit and has to be built to the [2024 Ontario Building Code](https://www.publications.gov.on.ca/301880): ceilings of at least 1.95 m, a fire separation between the two units, smoke alarms linked through the whole house, and an escape window or door on every floor with a bedroom. Your town sets the zoning, and as of October 2026 every lower-tier town in Durham Region, Ontario allows at least one unit in the house, and several, Whitby and Pickering among them, make you register it.

## Key takeaways

- Ceilings in a secondary suite must be at least 1.95 m, and 1.85 m under beams and ducts, under Div. B 9.5.3.1. of the [2024 Building Code Compendium](https://www.publications.gov.on.ca/301880).
- The units are separated by a 45-minute fire separation, or in a house with one secondary suite by 15.9 mm Type X drywall on both sides of walls and under the floor framing (9.10.9.16., [Building Code](https://www.publications.gov.on.ca/301880)).
- Every bedroom level needs a window with an opening of at least 0.35 m2 and no side under 380 mm, unless a door on that level leads outside (9.9.10.1., [Building Code](https://www.publications.gov.on.ca/301880)).
- On urban residential land, the [Planning Act](https://www.ontario.ca/laws/statute/90p13) stops a town from prohibiting three units on a lot or requiring more than one parking space per added unit.
- Whitby charges $268 to register an additional dwelling unit under By-law 8156-25, per the [Town's ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/).

## What makes a basement apartment legal in Ontario?

A basement apartment is legal when three things line up: zoning allows the unit, a building permit was issued and closed with final inspections, and the unit is registered where the town requires it. A finished basement with a kitchen and a side door isn't legal on its own, however good the finish looks.

The permit matters even if you build nothing new. Section 10 of the [Building Code Act](https://www.ontario.ca/laws/statute/92b23) requires a permit to change the use of a building where the change increases the hazard, and turning one dwelling into two does that. Electrical work in the new unit has to be done by a Licensed Electrical Contractor, who files a notification with the [Electrical Safety Authority](https://esasafe.com/compliance/finding-the-right-contractor/) before starting. A new gas line or appliance needs a TSSA-registered gas contractor under [O. Reg. 212/01](https://www.ontario.ca/laws/regulation/010212).

One definition shapes everything else. The Code defines a secondary suite as a self-contained unit in a building that holds only one other dwelling unit plus common spaces (Div. A 1.4.1.2.). Most of the easier rules below apply to a "house with a secondary suite". If you plan a third unit in the same house, it's no longer that kind of building and stricter rules start to apply, so talk to your building department early. Our [Bill 23 guide](https://www.jarviscontracting.ca/guides/bill-23-additional-units-ontario) covers how many units your town allows.

## What does the Ontario Building Code require for a basement apartment?

As of October 2026, these are the Code rules homeowners ask about most, all from the [2024 Building Code Compendium](https://www.publications.gov.on.ca/301880) (O. Reg. 163/24):

| Requirement | Minimum rule | OBC article |
|---|---|---|
| Ceiling height in the suite | 1.95 m | Div. B 9.5.3.1.(2) |
| Clear height under beams and ducts | 1.85 m | 9.5.3.1.(3) |
| Fire separation between units | 45-minute rating | 9.10.9.16.(1) |
| House with a secondary suite, alternative | Continuous smoke-tight 15.9 mm Type X drywall, both sides of walls and underside of floor framing | 9.10.9.16.(4) |
| Sprinklered house | The fire-resistance rating of that separation can be waived | 9.10.9.16.(5) |
| Smoke alarms | Interconnected, hard-wired or wireless, so one sounds them all across the house | 9.10.19.5.(2) |
| Bedroom escape window | Openable from inside without tools, 0.35 m2 opening, no dimension under 380 mm | 9.9.10.1.(1) |
| Window well | At least 550 mm clear in front of the window | 9.9.10.1.(3) |
| Route out of the suite | Not through the other unit or a service room | 9.9.7.5.(1) |
| Private stairs | Rise no more than 200 mm, run at least 255 mm | Table 9.8.4.1. |
| Headroom over stairs | 1,950 mm in a house with a secondary suite | 9.8.2.2.(3) |

Note: this is a summary of the most-asked articles, not the whole Code; your permit drawings have to cover every article that applies, and the building department reviews them.

### Ceiling height

The 1.95 m rule is the one that decides many basements. For comparison, an ordinary finished basement in a single-family house only needs 2,100 mm over 75% of the basement area, dropping to 1,950 mm under beams and ducts (Table 9.5.3.1.). The suite figure is lower, and the parts of each room that meet it have to connect to the room's entry (9.5.3.1.(4)); ask your building department how they'll measure your rooms. If your joists sit too low, the options are lowering the floor by underpinning or bench footings, or moving ducts. Our [cost guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) has our price ranges.

### Fire separation

Many two-unit conversions use the drywall route in Sentence (4): a continuous, smoke-tight layer of 15.9 mm Type X on both sides of the walls between units and on the underside of the floor framing above the basement. The word that matters is "continuous". Pot lights, duct runs and the furnace room all break the layer unless they're detailed properly. In a sprinklered house the rating can be waived (9.10.9.16.(5)).

### Escape windows and smoke alarms

Each floor with a bedroom needs one escape window, sized as in the table, unless a door on that level opens straight outside. The 1,000 mm maximum sill height doesn't apply in basements, but a window opening into a well needs 550 mm of clear space in front of it (9.9.10.1.(2) and (3)). Smoke alarms in both units have to be linked so an alarm in the basement sounds upstairs, and the reverse (9.10.19.5.(2)).

### The way out

The suite's route to the exit can't pass through the other unit or a service room such as a shared furnace room (9.9.7.5.(1)). That's why a separate entrance, or a shared vestibule that belongs to neither unit, is the usual answer. The federal tax credit for a family suite separately requires a private entrance, which we cover in the [cost guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario).

## What do Durham towns allow and require?

The Planning Act sets a floor, and each town's zoning by-law fills in the details: parking, path to the entrance and registration. As of October 2026, here's what the five lakeshore towns publish:

| Town | Units allowed on a lot | Parking | Registration | Source |
|---|---|---|---|---|
| Whitby | Up to 3 ADUs (4 homes): 2 in the house plus 1 accessory, or 3 in the house; 1 on Oak Ridges Moraine and Greenbelt lots | 1 per ADU; none in a Protected Major Transit Station Area | Required, By-law 8156-25, $268 ($534 if found through a complaint) | [Whitby Zoning By-law 1784, s.4](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) |
| Oshawa | Max 3 units, max 1 in an accessory building | 1 extra space per unit | Two-unit house registration issued through the permit; pre-July 1994 units through Municipal Licensing | [Oshawa accessory apartments page](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/) |
| Ajax | Up to 3 attached ADUs, or 2 attached plus 1 detached | Not covered in our source | No current program found | [Ajax Zoning By-law 95-2003, s.4.4](https://ajax.ca/wp-content/uploads/2026/04/4-Section-4-General-Provisions_2026-March-Consolidation-Final.pdf) |
| Pickering | Max 2 ADUs: 2 in the house, or 1 in the house plus 1 accessory; 1 on the Oak Ridges Moraine | 1 per ADU; near Kingston Road or Pickering GO, 1 for the first and 0 for the second | Mandatory, By-law 8040/23 | [Pickering Zoning By-law 8149/24](https://corporate.pickering.ca/WebLink/DocView.aspx?id=258309&dbid=1&repo=PICKERING) |
| Clarington | 2 ADUs in Courtice, Bowmanville, Newcastle and Orono: 1 in the house plus 1 accessory; 1 on Moraine and Greenbelt land | House keeps 2 spaces, plus 1 per ADU | Not found | [Clarington ADU page](https://www.clarington.net/homes-and-property/building-or-renovating/additional-dwelling-units/) |

Note: these are zoning summaries for typical urban lots as of October 2026; hazard lands, Moraine and Greenbelt lots and site-specific zoning can change the answer for your property.

Whitby also requires an unobstructed path to the unit's entrance at least 1.2 m wide and 2.1 m high, per [By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf). Pickering's by-law asks for a 1.2 m path from each unit's entrance to the street. A side-yard entrance on a narrow lot can fail this test before the Building Code even comes into it, so measure the side yard first.

Provincial law limits what a town can demand. On urban residential land, meaning a settlement area on municipal water and sewer, the [Planning Act](https://www.ontario.ca/laws/statute/90p13) bars zoning that requires more than one parking space per added unit or sets a minimum unit size. [O. Reg. 299/19](https://www.ontario.ca/laws/regulation/190299) lets anyone live in the unit, related or not, and allows it whatever the age of the house.

## Do you have to register a basement apartment in Durham Region?

You do in Whitby, Pickering, Scugog and Uxbridge. Whitby's registration by-law, 8156-25, charges $268, or $534 if the Town finds the unit through a complaint, per its [ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/). Pickering makes registration with its Building and Fire Services mandatory under By-law 8040/23, per [Pickering's ADU page](https://www.pickering.ca/business-building-development/building-and-renovating/additional-dwelling-units/); we didn't find the fee published there. Scugog requires registration before anyone moves in, per its [ADU page](https://www.scugog.ca/building-development/additional-dwelling-units/), and Uxbridge asks owners to register two-unit houses through its [secondary suites page](https://www.uxbridge.ca/doing-business/building-and-construction/secondary-suites).

Oshawa issues a two-unit house registration as part of the building permit, per its [accessory apartments page](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/). We found no current registration program in Ajax and none published by Clarington, as of October 2026. If you're in Whitby and building now, the Town's incentive needs the unit registered by 31 March 2027; see our [Whitby ADU incentive guide](https://www.jarviscontracting.ca/guides/whitby-adu-incentive). The permit itself, fees and timelines are in [basement permits in Durham Region](https://www.jarviscontracting.ca/guides/basement-permits-durham-region).

## How we approach a basement apartment

We're Jarvis Contracting, a family design-build firm based in Ajax. James Jarvis runs construction and his wife, Ceara Jarvis, runs design through her studio Juliette Interiors. We draw permit drawings in-house and build basements and additional units. We plan, draw and build to the Ontario Building Code; the town's building department reviews the drawings and inspects the work.

The first visit is a tape measure, not a mood board: joist height, duct runs, the foundation wall where an entrance could go and the side-yard width for the path. Those four measurements show if you're looking at a straightforward suite or an underpinning job. Read more on our [basement renovations page](https://www.jarviscontracting.ca/basement-renovations).

## Questions

### What is the minimum ceiling height for a basement apartment in Ontario?

The minimum ceiling height for a basement apartment in Ontario is 1.95 m, with 1.85 m allowed under beams and ducts, under Div. B 9.5.3.1. of the 2024 Building Code. The areas that meet it have to connect to the room's entry. If your basement is lower, the usual fixes are lowering the floor or moving ductwork.

### Does a basement apartment need its own entrance in Ontario?

The Building Code says a basement apartment's route to the exit can't pass through the other unit or a service room (9.9.7.5.). In practice that means a separate entrance or a shared vestibule that belongs to neither unit. The federal Multigenerational Home Renovation Tax Credit separately requires a private entrance.

### Do basement bedrooms need an egress window in Ontario?

Basement bedrooms do need an escape route in Ontario. Every floor level with a bedroom needs at least one window that opens from inside without tools, with an opening of at least 0.35 m2 and no dimension under 380 mm, unless a door on that level leads directly outside. A window that opens into a well needs 550 mm of clear space in front of it.

### What fire separation does a basement apartment need?

The default is a 45-minute fire separation between units. In a house with one secondary suite, the Code allows a continuous, smoke-tight layer of 15.9 mm Type X drywall on both sides of the walls between the units and under the floor framing instead (9.10.9.16.(4)). In a sprinklered house the rating can be waived.

### Do I have to register a basement apartment in Whitby?

As of October 2026, Whitby requires every additional dwelling unit to be registered under By-law 8156-25, for a $268 fee, or $534 if the Town finds the unit through a complaint. Registration is also a condition of Whitby's ADU incentive, which needs the unit registered by 31 March 2027.

### Can my basement apartment be rented to someone who isn't family?

A basement apartment can be rented to anyone. Ontario Regulation 299/19 lets anyone live in an additional residential unit, related to the owner or not. The federal tax credit for a family suite is the exception: it only applies when the unit houses a senior or a disabled adult relative.

# Whitby's ADU incentive: fees refunded for applications by 31 Dec 2026

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-05.

The Town of Whitby will pay back the permit and related fees on an additional dwelling unit (ADU) if your complete building permit application is in by 31 December 2026 and the unit is registered by 31 March 2027 ([Town of Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)). The program is funded by the federal Housing Accelerator Fund. A detached ADU in Whitby can be up to 75 m² and 4.5 m tall, and every ADU must be registered for $268, as of October 2026.

## Key takeaways

- Whitby's incentive can reimburse the ADU building permit fee, the registration inspection fee, a curb cut fee, a below-grade entrance fee and education development charges on detached ADUs, for permits issued after 1 April 2024 ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)).
- The application must be deemed complete by 31 December 2026, and the Town asks you to submit "at least two weeks prior", so plan on mid-December at the latest ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)).
- Whitby zoning allows up to three ADUs on a residential lot, four homes in all, with no more than one in an accessory building ([Zoning By-law 1784 s.4(dd)](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf)).
- A detached ADU can have up to 75 m² of gross floor area, stand up to 4.5 m high in residential zones, and sit 1.2 m from interior side and rear lot lines ([By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf)).
- Registration under By-law 8156-25 costs $268, or $534 if the unit is found through a complaint ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)).
- Whitby and Pickering share a catalogue of six pre-reviewed detached ADU designs from 264 to 634 sq ft ([design catalogue](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/whitby-and-pickering-additional-dwelling-unit-regional-design-catalogue/)).

## What does Whitby's ADU incentive pay back?

It reimburses the Town's own fees on the unit, not the cost of building it. The Town lists "the ADU Building Permit Fee, ADU Registration Inspection Fee, Curb Cut Fee, Below Grade Entrance Fee, and Development Charges for Education applicable to detached ADU's" ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)). Minor variance fees are not eligible.

Here's what those fees are, as of October 2026:

| Fee | 2026 amount | Reimbursable? | Source |
|---|---|---|---|
| ADU building permit, alterations (line BGP-10) | $10.65 per m² | Yes | [Schedule N, 2026](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) |
| Below-grade entrance or underpinning | $305 flat | Yes | [Schedule N, 2026](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) |
| Education development charges, detached ADU | $7,535 per unit (public $4,349, Catholic $3,186) | Yes | [Durham education DCs, May 2026 to April 2027](https://media-002-ca.cdn.govstack.com/pickeringca-009-ca/media/wl4en3hp/developmentcharges_citywide_2026-2027final.pdf) |
| Curb cut | Not printed on the ADU page | Yes | [Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/) |
| ADU registration (By-law 8156-25) | $268 ($534 after a complaint) | The registration inspection fee is listed; the page doesn't say the $268 itself is | [Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/) |
| Minor variance, residential | $1,526 | No | [Whitby minor variance fees](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) |

Note: amounts from the Town's 2026 schedules as of October 2026; the education DC figure is the Durham per-unit rate, and the Town decides what it reimburses on your file under the incentive agreement.

On a 60 m² basement apartment with a new below-grade entrance, the permit fee at the ADU rate works out to $639 plus the $305 entrance fee (our arithmetic from Schedule N). The bigger number is on detached units: Whitby says Town and Region development charges don't apply to an ADU that meets Ontario Regulation 454/19, but education development charges "would also still apply for all detached ADU's", and those are what the incentive can cover ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)).

## What are the deadlines?

The dates are fixed, and the first one is close. As of October 2026, here's the sequence the Town sets out:

| Step | Deadline | Source |
|---|---|---|
| Permit issued (earliest that qualifies) | After 1 April 2024 | [Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/) |
| Submit the building permit application | At least two weeks before 31 December 2026 | same |
| Application deemed complete | 31 December 2026 | same |
| Sign the incentive agreement | 31 March 2027 | same |
| Register the ADU with the Town | 31 March 2027 | same |
| Repay the incentive if the unit isn't registered | 30 April 2027 | same |

Note: dates from the Town's ADU page as of October 2026; if the program changes, the Town's page governs.

"Complete" is the word to watch. Under the Ontario Building Code the permit clock starts only once an application has every form, schedule, drawing and fee ([2024 Building Code Compendium](https://www.publications.gov.on.ca/301880)). And if your plan needs a minor variance, Whitby says the decision "must be final and binding when the complete building permit application is submitted" ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)). That means a Committee of Adjustment hearing plus the appeal period, all before December. If you're starting from scratch in October and you need a variance, the incentive may already be out of reach. If your unit fits the zoning as drawn, there's still time, but not much.

## How many units can I add in Whitby, and how big?

Up to three ADUs on a residential lot that permits a detached, semi, link or street townhouse dwelling: two in the house and one in an accessory building, or three in the house ([By-law 1784 s.4(dd)](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf)). That's one more than Ontario's floor of three units on an urban serviced lot, and one more than Pickering allows. On Oak Ridges Moraine and Greenbelt Protected Countryside lots, the limit is one ADU, and none are allowed on Environmental Protection, Natural Heritage System or hazard lands.

For a detached unit in a garage, coach house or backyard building, the zoning sets:

- 75 m² maximum gross floor area (about 807 sq ft);
- 4.5 m maximum height in residential zones;
- 1.2 m from interior side and rear lot lines, 3.0 m from an exterior side lot line;
- an unobstructed path to the ADU entrance at least 1.2 m wide and 2.1 m high;
- one parking space per ADU (a reduced 2.5 m by 5.0 m space and tandem parking are allowed), and none in a Protected Major Transit Station Area.

All from [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf), which covers most of Whitby including Brooklin. Downtown Whitby falls under By-law 2585, amended for ADUs by By-law 8142-24, so check that by-law for a downtown lot. The by-law also excludes a detached ADU from the lot's maximum lot coverage, which matters on Whitby's older R1 to R3 lots capped at 20%. Our [Bill 23 units guide](https://www.jarviscontracting.ca/guides/bill-23-additional-units-ontario) compares these limits with Oshawa, Ajax, Pickering, Clarington and the rest of the GTA.

## What are the Whitby and Pickering pre-approved ADU designs?

They're six detached ADU designs that the two towns reviewed ahead of time, funded by the Housing Accelerator Fund. Every one is under Whitby's 75 m² cap:

| Design | Size | Layout |
|---|---|---|
| Bob Abrahams Architect Corp. Model 20P | 264 sq ft | One bedroom, one bathroom |
| AAA Architects Inc. Model 8-2 | 409 sq ft | Studio, one bathroom |
| Jensen Design Services | 450 sq ft | One bedroom, one bathroom |
| AAA Architects Inc. Model 9-4 | 473 sq ft | One bedroom, one bathroom |
| Bob Abrahams Architect Corp. Model 30F | 484 sq ft | One bedroom, one bathroom |
| CMHC Housing Design Catalogue, ADU 01 | 634 sq ft | One bedroom, one bathroom |

Note: from the [Whitby and Pickering design catalogue](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/whitby-and-pickering-additional-dwelling-unit-regional-design-catalogue/) as of October 2026; the catalogue doesn't publish a price for the plans.

A catalogue design saves design time; it doesn't skip the permit. The catalogue says "Building permits will be reviewed based on site-specific conditions", and the site plan and the "applicable foundation and HVAC plans" are bought from the designers. You still need a site plan that shows the setbacks and the 1.2 m path, the servicing route for water, sewer and power, and a foundation that suits your soil. The designs top out at one bedroom, so for a two-bedroom unit you're drawing your own within the 75 m².

## Do I need to register a Whitby ADU, and what else applies?

Yes. Whitby requires every ADU to be registered with the Town under By-law 8156-25, on top of the building permit, for $268 ([Whitby ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)). It's $534 if the unit comes to light through a complaint, and $107 to transfer a registration. The Town's FAQ lists prosecution, voided insurance and liability as the risks of a non-compliant unit.

Whitby also lies in the Central Lake Ontario Conservation Authority (CLOCA) watershed, and CLOCA says new structures and additional dwelling units in its regulated areas near streams, wetlands and the shoreline need its permit ([CLOCA](https://www.cloca.com/inquiries-permits)). And a basement apartment has to meet the Ontario Building Code's rules for a second unit, which our [legal basement requirements guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario) sets out.

## Where we come in

We're based in Ajax, next door to Whitby, and we draw permit drawings in-house, so we can take a basement apartment, a garage conversion or a backyard unit from a measured drawing to a permit application without waiting on an outside designer. With the December deadline, that's the part that matters most. If you've bought a catalogue design, we can prepare the site-specific drawings around it and build it. See our garden suites page and [basement renovations page](https://www.jarviscontracting.ca/basement-renovations) for how we approach each, and our [legal basement cost guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) for what the build itself tends to cost.

## Questions

### What is Whitby's additional dwelling unit incentive?

Whitby's additional dwelling unit incentive is a Housing Accelerator Fund program that reimburses the Town's ADU fees: the ADU building permit fee, registration inspection fee, curb cut fee, below-grade entrance fee and education development charges on detached ADUs. It applies to permits issued after 1 April 2024 with a complete application by 31 December 2026.

### What is the deadline for Whitby's ADU incentive?

The ADU building permit application must be deemed complete by 31 December 2026, and Whitby asks for submissions at least two weeks before that. The unit must be registered and the incentive agreement signed by 31 March 2027, or the money is repayable by 30 April 2027.

### How big can a detached ADU be in Whitby?

A detached additional dwelling unit in Whitby can have up to 75 m² of gross floor area and be up to 4.5 m high in residential zones, with 1.2 m interior side and rear setbacks and 3.0 m on an exterior side, under Zoning By-law 1784 as of October 2026.

### How many additional dwelling units are allowed in Whitby?

Whitby allows up to three additional dwelling units on a residential lot, for four homes in total, with no more than one in an accessory building. Lots on the Oak Ridges Moraine or in the Greenbelt Protected Countryside are limited to one.

### Does Whitby charge development charges on an ADU?

Whitby says Town and Region development charges don't apply to an ADU that meets Ontario Regulation 454/19. Education development charges still apply to detached ADUs, currently $7,535 per unit in most of Durham Region, and the incentive can reimburse them.

### Can I use the Whitby and Pickering pre-approved ADU designs?

Yes. The Towns of Whitby and Pickering publish six pre-reviewed detached ADU designs from 264 to 634 sq ft. You buy the plans from the designer, and the building permit is still reviewed against your lot's site-specific conditions.

# How to Keep a Renovation Moving: Decisions and Communication

By Jarvis Contracting. Published 2026-10-05, updated 2026-10-09.

A useful renovation update tells you what happened, what happens next and which decisions need your attention. Agree on that routine before work starts. A long stream of messages is less useful than a short record that everyone can find.

## Set up one decision record

Choose one place for drawings, selections and approved changes. Give each document a date or revision number. A photograph sent by text can explain a problem, but it should not become the only record of an instruction that changes the work.

Before the first day on site, agree who can approve changes, who answers day-to-day questions and how urgent issues will be raised. If two household members are involved, decide how they will reach one answer before instructing the team.

## What a weekly update should contain

Ask for four things: completed work, upcoming work, decisions needed and changes to the expected sequence. Each open decision should have a named owner and a date when the answer is needed.

| Decision | Information to record |
|---|---|
| Tile selection | Product, size, layout, grout and delivery date |
| Cabinet change | Marked-up drawing, price and schedule effect |
| Unexpected wall condition | Photograph, proposed solution and approval |
| Inspection | Stage, booking status and any follow-up work |

A sample update might say that rough plumbing is complete, the shower valve needs approval this week, and boarding will follow the inspection. That is an example of a useful format, not a report from a current Jarvis job.

## Separate a question from an approval

Asking whether an island could be longer is not the same as approving a new cabinet order. Confirm the revised scope, price and timing together before a change proceeds. Keep that approval alongside the revised drawing, rather than relying on a remembered conversation. Ontario's [renovation consumer guidance](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) is a useful reference when reviewing written estimates and agreements.

## See a project with real decisions

At [Bellamy](https://www.jarviscontracting.ca/projects/bellamy), the work included structural changes, a kitchen, mudroom and office. The case study and site films show the decisions behind the finished rooms. Our [process](https://www.jarviscontracting.ca/process) explains how a project moves from the first visit through design, construction and handover.

## Questions

### How often should my contractor update me?

Agree on a regular update and a separate route for urgent decisions. The right frequency depends on the stage of the job; what matters is that decisions are recorded before they hold up work.

# How to Create a Realistic Renovation Budget in Ontario

By Jarvis Contracting. Published 2026-10-04, updated 2026-10-13.

A realistic renovation budget in Ontario is the construction price plus the lines most quotes leave out: drawings, engineering, the permit fee, 13% HST and a contingency. Our permit drawings for an addition run $6,000 to $12,000 in 2026. That price leaves out permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen, so each needs a line of its own. Build the budget from those lines first, then fit the design to it, not the other way round.

## Key takeaways

- Our 2026 price for permit drawings is $6,000 to $12,000 for an addition and $4,000 to $8,000 for a basement apartment. It leaves out permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen.
- A 1,000 sq ft addition pays about $2,078 in permit fees in Whitby at $22.37 per m² under the [Town's 2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf), and about $1,446 in Oshawa at $15.56 per m² under [By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).
- Our 2026 range for a 600 to 1,200 sq ft second storey is $300,000 to $800,000 before HST, and work on the floor below, like a kitchen or bathrooms, adds to it.
- HST in Ontario is 13%, made up of the [5% federal portion](https://www.ontario.ca/page/ontario-new-home-affordability-payment) and the [8% provincial portion](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html), and most published price ranges, ours included, are before it.
- Under Ontario's consumer protection rules, the final price can't exceed a written estimate by more than 10% unless you agree to changes, according to the province's [renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) (updated 6 August 2026).

## What goes in a renovation budget besides construction?

Construction is the biggest line, but it isn't the whole budget. Before a crew shows up you pay for design, permit drawings, structural engineering and the permit. During the job you pay HST on almost all of it. And you carry a contingency for what the walls hide.

These are the lines we see left off most often, with our own 2026 prices and the towns' fees:

| Line item | 2026 figure | Basis |
|---|---|---|
| Permit drawings, addition | $6,000 to $12,000 | Our price |
| Permit drawings, basement apartment | $4,000 to $8,000 | Our price |
| Permit drawings, garden suite | $5,000 to $15,000 | Our price |
| Minor variance, residential lot | $1,526 in Whitby, $856 per lot in Oshawa | [Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) and [Oshawa](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/) |
| Building permit, addition, Whitby | $22.37 per m² | [Town of Whitby 2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) |
| Building permit, addition, Oshawa | $15.56 per m² | [Oshawa fee by-law](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) |
| HST | 13% | [Ontario](https://www.ontario.ca/page/ontario-new-home-affordability-payment) and [CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html) |

Note: the drawing prices are ours for 2026 and cover drawings only. Permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra. The permit and variance fees are the towns' own 2026 schedules, and none of these figures includes HST.

Two more lines don't fit a table: where you live while the roof is off, and the old panel, furnace or drain that shows up once the walls are open. Name both before anyone signs.

## Why do renovation quotes for the same job differ so much?

Quotes differ mostly because they price different jobs. One owner on RedFlagDeals posted general contractor quotes of $380,000 to $397,000 for an addition, against $242,000 to manage the build themselves, and the GC quotes [carried no contingency](https://forums.redflagdeals.com/addition-estimates-all-over-place-updated-my-experience-getting-addition-2154634/11/) (forum post, read from a search snippet). Another owner of a 1,300 sq ft bungalow got a [$280,000 second-storey quote that left out the main floor](https://forums.redflagdeals.com/adding-storey-real-costs-1975637/), and reckoned another $80,000 to $100,000 would bring it to $400,000 to $450,000.

That second story is the common one. A second storey needs a new stair, often a steel beam where a bearing wall comes out, ductwork run up through the main floor, and patching wherever the trades opened a wall. Some quotes price all of that, and some price only the box on top.

So before you compare totals, compare scope. Lay the quotes side by side and check each one for the main floor, the permit and drawings, the exterior (siding, roofing, eavestroughs), the basement, HST and contingency. If one quote is $100,000 lower, find the $100,000 it left out. Our guide to [fixed price and cost-plus contracts](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus) covers how the contract type changes what a quote promises.

## Allowances or fixed selections?

An allowance is a placeholder: a dollar figure in the contract for something you haven't picked yet, like cabinets, tile, plumbing fixtures or flooring. If your pick costs more, you pay the difference. The RedFlagDeals owner above went over their own budget on cabinets, which is the usual way allowances bite.

Allowances let a job get priced before every finish is chosen, which is useful. The trouble starts when an allowance is set low to make a quote look cheap. Ask what each allowance would buy, and pick the big items (cabinets, windows, flooring) before the price is fixed, so they're numbers rather than guesses.

## How much contingency should you carry?

Size the contingency to the house, not to a rule of thumb. We'd carry more for an older house, a job that opens a lot of existing structure, or anything touching the foundation.

Contingency pays for what nobody could see: rot under a bathroom floor, knob-and-tube wiring in a wall you meant to keep, a footing that needs work before it carries a second floor. Upgrades you choose halfway through, like a bigger window, are change orders with their own price, and they come from a different pot.

Ontario puts two limits on contractors that help here. The final price can't exceed a written estimate by more than 10% without your agreement to changes, and the province recommends a deposit of no more than 10%, both on its [renovation rights page](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) (updated 6 August 2026). Our [payment schedule guide](https://www.jarviscontracting.ca/post/home-renovation-payment-schedule-ontario-guide) shows how to tie the rest of the money to work you can see.

## Which decisions should be made before the permit?

Make the decisions that move walls, pipes or structure before the permit drawings are finished. That means the layout, where the plumbing stack runs, window sizes and locations, which walls come out and what holds the load once they're gone, and whether the main floor is part of the job.

Each of those is on the permit drawings. Change one after the permit is issued and you're back at the drawing table, then back at the building department for a permit amendment, while the crew waits. Paint colours and tile can wait; structure has to be settled first.

Starting work early to save time costs money too. Whitby's fee schedule adds a charge of the greater of $100 or 25% of the application fee for [work started before a permit application](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf), and Oshawa adds 25% or 50% of the permit fee under [By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).

## Putting the lines together: a second storey in Whitby

Here is how those lines stack up for a second storey in Whitby, using our 2026 prices and the Town's 2026 fees. It shows the method, not a price for your house:

| Line | 2026 figure | Basis |
|---|---|---|
| Construction, 600 to 1,200 sq ft second storey | $300,000 to $800,000 | Our range |
| Work on the floor below (kitchen, bathrooms) | Adds to the line above | Priced with the job |
| Permit drawings for an addition | $6,000 to $12,000 | Our price |
| HVAC engineering and truss design | Not in the drawing price | Its own line |
| Whitby permit fee, new floor area | $22.37 per m² | [Town of Whitby 2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) |
| Minor variance, if the height needs one | $1,526 | [Town of Whitby application form](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) |
| Contingency | Sized to the house | See above |
| HST | 13% | [Ontario](https://www.ontario.ca/page/ontario-new-home-affordability-payment) and [CRA](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html) |

Note: our ranges are before 13% HST and aren't a quote; James prices the whole job in writing, at a fixed price, before design starts. The drawing price leaves out permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen, which is why those have rows of their own. The town's fee schedule lists no HST on the permit fee, so HST applies to everything else.

The construction line is the biggest, but the money you need in the bank is that line plus every row under it. For more on what drives the construction line, see our [second-storey cost guide](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario) and [home addition cost guide](https://www.jarviscontracting.ca/guides/home-addition-cost-ontario).

## What's different about budgeting in Durham Region?

Your town sets the permit fee and the zoning, and the conservation authority may want its own permit. Whitby and Oshawa sit side by side and still differ, as of October 2026:

- **Permit fees.** Whitby charges $22.37 per m² for additions and $10.65 per m² for alterations, with a $305 minimum ([2026 schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)). Oshawa charges $15.56 per m² for additions, $7.79 per m² for a finished basement, and a $160 minimum ([By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf)).
- **Minor variances.** If the addition breaks a zoning limit, the Committee of Adjustment hears it first. The application fee is $1,526 for a residential lot in [Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) and $856 per lot in [Oshawa](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/). Whitby's [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) sets an 8.5 m height limit in its R1 to R3 zones; Oshawa's [Zoning By-law 60-94](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf) allows 9.0 m in R1-A to R1-E. A tall second storey can run into those limits.
- **CLOCA.** Both towns sit in the Central Lake Ontario Conservation Authority's area. Near a creek, wetland or the lake shore, an addition needs a CLOCA permit as well: $535 for a Minor Permit B, or $1,990 plus $3,640 per technical report for a Standard Permit C ([CLOCA 2026 fees](https://www.cloca.com/_files/ugd/6cdd05_ca1ea5bbdaa34f3ca770f69ab8f830e4.pdf)).
- **Development charges.** These don't apply to an addition. Enlarging an existing home doesn't trigger them under the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27), so the $76,227 [regional charge](https://media-003-ca.cdn.govstack.com/durham-ca/media/vybhyyp2/durham-region-wide-development-charge-information-jul-1-2026.pdf) on a new house in Durham Region stays off your budget.

## How we build a budget with you

We start with a visit. James comes to the house, looks at the structure, the panel, the basement and the lot, and talks through what you want and what you want to spend, then gives you a rough estimate on the spot. If it works for you, he prices the whole job in a detailed proposal, and you sign the contract before design starts. Then Ceara Jarvis and her studio, Juliette Interiors, design the space and draw it, and a licensed engineer stamps the structure.

James's proposals are detailed, so the price rarely moves; if a design selection or a finish changes it, the change goes through a change order you sign. Then we apply for the permit, build with one crew, book the town's inspections as each stage is ready, and hand the house back.

We're writing up our projects as case studies now; the first is on our [projects page](https://www.jarviscontracting.ca/projects). [Greenwood](https://www.jarviscontracting.ca/projects/greenwood) was a ten-month renovation in Toronto that we took through design, permit and construction. Our [pricing page](https://www.jarviscontracting.ca/pricing) explains how we price, and [design-build](https://www.jarviscontracting.ca/design-build) explains why one team carrying design and price keeps the budget honest.

## Questions

### How much contingency should I add to a renovation budget in Ontario?

There's no single right percentage for a renovation contingency in Ontario: size it to the house. Carry more for an older house, foundation work, or a job that opens a lot of existing walls.

A renovation contingency covers hidden conditions, like rot, old wiring or a footing that needs work. Keep it separate from upgrades you choose along the way, which should be priced as change orders.

### Do renovation quotes in Ontario include HST?

Many renovation quotes and published price ranges in Ontario are before HST, so check. HST is 13%: the 5% federal portion plus the 8% provincial portion.

On a $300,000 renovation that is $39,000 of tax. Ask every contractor to show HST as its own line so you can compare quotes on the same basis.

### Can a contractor charge more than the estimate in Ontario?

Under Ontario's consumer protection rules, a contractor can't charge more than 10% above a written estimate unless you agree to changes. The province's renovation rights page, updated 6 August 2026, also says contracts over $50 must be in writing.

### How much are building permit fees for an addition in Whitby?

The Town of Whitby charges $22.37 per square metre for residential additions under its fee schedule effective 1 January 2026, with a $305 minimum. A 1,000 sq ft addition (about 92.9 m²) comes to about $2,078. Oshawa's rate for additions is lower, at $15.56 per square metre.

### Should I get drawings before I ask for quotes?

Getting drawings before quotes is what makes quotes comparable. Without drawings, each contractor prices their own idea of the job, and the totals can't be compared line by line.

Our permit drawings for an addition run $6,000 to $12,000 in 2026. That's drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra. A design-build firm does the drawings and the price together, so the design is priced as it's drawn.

### What should I do if my renovation plans come in over budget?

If renovation plans come in over budget, cut scope on paper before the permit, not on site after it. Simplify the roof line, keep plumbing where it is, phase the finishes, or leave a room for later.

The worst cut is the contingency. Taking it out makes the number fit today and guarantees a problem later.

# Planning a Bathroom Renovation in Vaughan

By Jarvis Contracting. Published 2026-10-03, updated 2026-10-09.

Plan a bathroom around the layout, water management and access for the work before choosing the tile. For a Vaughan home, start with the existing room, the proposed plumbing changes and the local approval requirements. A clear scope makes quotes much easier to compare.

## Keep the layout or move the fixtures?

Keeping the toilet, vanity and shower in the same positions can simplify the work, but it does not answer every question about the room. Check ventilation, storage, lighting and the condition of the surfaces behind the finishes.

If fixtures move, ask how drains and supply lines will reach their new positions and which ceilings or walls outside the bathroom may need to open. On an upper floor, that can affect the room below.

## Make water management part of the specification

Ask the contractor to identify the proposed shower assembly, drainage, waterproofing and how changes in surface level will be handled. A tile sample does not describe that assembly. Record who supplies the system and how the installation is documented before the tile goes on.

For approvals, use the [City of Vaughan](https://www.vaughan.ca/) building department as the starting point. Explain the planned plumbing, ventilation and structural work. The need for an approval depends on the work, not on whether the finish is described as cosmetic.

## Look closely at real room layouts

The [Moore Park photo essay](https://www.jarviscontracting.ca/projects/moore-park) shows a double vanity, hanging mirrors, a half wall and a glass shower. [West Lynde](https://www.jarviscontracting.ca/projects/west-lynde) offers a different palette, including its emerald-tiled shower. These are design references from the Jarvis portfolio; neither is presented as a verified Vaughan project.

When collecting inspiration, identify the feature you need: a place to set toiletries, accessible towel storage, a shower bench or two people using the vanity at once. That is a stronger brief than a list of colours alone.

## Plan life around the work

Decide which bathroom will remain available, where materials will be stored and how the work route through the house will be protected. Confirm who orders fixtures and what happens if a product arrives damaged.

Ask for a scope that separates demolition, repairs, rough work, waterproofing, finishes and fixtures. Our [bathroom service](https://www.jarviscontracting.ca/bathroom-renovations) and [pricing overview](https://www.jarviscontracting.ca/pricing) help prepare that conversation. The final design and estimate should respond to the actual house.

## Questions

### Is a bathroom quote comparable if it only lists fixtures and tile?

Not reliably. It should also explain demolition, preparation, plumbing and electrical work, waterproofing, installation, disposal and exclusions. Compare those items before comparing the totals.

# Bungalow Renovation in Oshawa: Your Four Real Options

By Jarvis Contracting. Published 2026-10-02, updated 2026-10-13.

An Oshawa bungalow has four real ways to grow: open up the main floor, add a second storey, turn the basement into a registered second unit, or build a garden suite in the yard. Oshawa charges [$7.79 per m² for interior finishing and $15.56 per m² for new living space](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) as of October 2026, and its zoning allows [9.0 m of height and 40% lot coverage](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf) in the R1-A to R1-E zones. Which option fits depends on your lot, your basement and who's going to live there.

## Key takeaways

- Oshawa's 2026 permit fee is $15.56 per m² for an addition or a habitable accessory building and $7.79 per m² for basement finishing, under [Building By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).
- In the R1-A to R1-E zones of [Zoning By-law 60-94](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf), a house can be 9.0 m tall and cover 40% of the lot, or 45% with an accessory apartment.
- Oshawa issued 246 two-unit house registration certificates in 2023 and 338 in 2024, according to the [Oshawa open data](https://www.arcgis.com/sharing/rest/content/items/97d92126eeae4430885d6225df0ff2a0/data).
- All accessory buildings on an Oshawa lot, a garden suite included, are capped at 60 m² of ground floor (90 m² in R1-G and R1-H), per the [Oshawa accessory apartment rules](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/).
- A minor variance in Oshawa costs [$856 per lot](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/) at the Committee of Adjustment.
- Starting work with no permit application adds a [50% surcharge](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) to the Oshawa permit fee.

## Which bungalow renovation fits your house?

Start with the problem, not the project. If the house feels cramped but has enough bedrooms, opening the main floor may be all it needs. If you need more bedrooms, you either go up or go out. If you need a separate home for a parent, an adult child or a tenant, it's the basement or the yard.

Here is how the four options compare in Oshawa, as of October 2026:

| Option | What you get | Oshawa permit fee | Rule to check first |
|---|---|---|---|
| Open the main floor | A bigger kitchen and living space in the same footprint | [$7.79 per m²](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) | Whether the wall is load-bearing (an engineer decides) |
| Add a second storey | Bedrooms and a bathroom upstairs, same lot coverage | [$15.56 per m²](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) | [9.0 m height limit](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf) in R1-A to R1-E |
| Basement second unit | A self-contained apartment with its own entrance | [$7.79 per m²](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) | [One extra parking space per unit](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/) |
| Garden suite | A small separate house in the backyard | [$15.56 per m²](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) | [60 m² ground floor for all accessory buildings](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/) |

Note: fees are the City of Oshawa's 2026 rates per m² of floor area, before the minimum fee of $160; they are permit fees only, not construction costs. Zoning limits depend on your lot's zone.

## Opening up the main floor of a bungalow

Most bungalows have a bearing wall running down the middle, between the kitchen and the living room. Taking it out is very doable, but it's structural work. A licensed engineer sizes a beam to replace it, the posts at each end carry point loads down to footings in the basement, and the ducts, wiring and sometimes a plumbing vent inside that wall have to go somewhere new.

It needs a building permit, and electrical changes go through the Electrical Safety Authority with a [licensed electrical contractor](https://esasafe.com/compliance/finding-the-right-contractor/). Our guide to [removing a load-bearing wall](https://www.jarviscontracting.ca/post/main-floor-renovation-contractors-gta-the-design-build-guide-to-your-dream-layout) covers beams, permits and the kitchen layout in detail. If you're doing the kitchen at the same time, our [kitchen cost post](https://www.jarviscontracting.ca/post/average-cost-of-kitchen-remodel-in-ontario-2026-budgeting-guide) has our 2026 ranges.

## Adding a second storey to an Oshawa bungalow

Going up doubles your space without giving up the yard, and in Oshawa's R1-A to R1-E zones you have [9.0 m of height](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf) to work with. At $15.56 per m², a 1,000 sq ft (92.9 m²) second storey works out to a permit fee of about $1,446, calculated from the [Oshawa fee schedule](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).

The fee is the easy part. The hard part is whether the foundation and main-floor walls can carry a new floor, which an engineer confirms, and where you'll live while the roof is off. Our 2026 range for a 600 to 1,200 sq ft second storey is $300,000 to $800,000 before HST, and any work on the main floor below adds to it. Our [second storey planning guide](https://www.jarviscontracting.ca/post/second-storey-addition-contractors-ontario-the-design-build-guide-to-planning-upward) walks through the structure, permits, zoning and HST rebate in Durham Region.

## Turning the basement into a second unit

Basement apartments are common in Oshawa. The City issued [246 two-unit house registration certificates in 2023, 338 in 2024 and 251 from January 1 to November 26, 2025](https://www.arcgis.com/sharing/rest/content/items/97d92126eeae4430885d6225df0ff2a0/data). Across Durham Region, Ontario, permits were issued for [999 additional residential units in 2024 and 1,004 in 2025](https://media-003-ca.cdn.govstack.com/durham-ca/media/vc5lqmuu/2026-info-54-2025-annual-building-activity-review.pdf).

When you build the unit through a building permit, Oshawa issues the [two-unit house registration](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/) as part of the process. Units that existed before July 1994 are legalised through Municipal Licensing instead. The rules we plan around:

- **Parking.** One extra space for each accessory unit, so three spaces for a house with two units, each 2.75 m by 5.75 m, with [50% of the front yard kept as landscaped open space](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/).
- **Ceiling height.** The Building Code asks for [1.95 m in a secondary suite](https://www.publications.gov.on.ca/301880), and 1.85 m under beams and ducts. Older bungalow basements sometimes fall short, which means lowering the floor or rerouting ducts.
- **Fire separation.** Between the units, the Code allows a continuous smoke-tight barrier of [15.9 mm Type X drywall](https://www.publications.gov.on.ca/301880) on the walls and the underside of the floor framing in place of a rated assembly.
- **Lot coverage.** Oshawa raises the limit to [45% when the lot has an accessory apartment](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf).

You don't pay development charges for a second unit in an existing house under the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27). For scale, a new single detached house in Oshawa carries [$130,682 in development charges](https://www.oshawa.ca/business-development/planning-and-development/development-charges/). On cost, our 2026 range is $45,000 to $95,000 to legalise a basement that's already finished, and $80,000 to $180,000 for a full legal basement apartment. Our [legal basement requirements guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario) goes deeper.

## Building a garden suite behind an Oshawa bungalow

A garden suite suits a parent who wants their own door, or a bungalow on a deep lot. Oshawa counts it as an accessory building, and all the accessory buildings on the lot together can't exceed [8% of the lot area, 50% of the house's coverage or 60 m² of ground floor](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/) (90 m² in R1-G and R1-H). It can be 4.5 m tall, sit 0.6 m from the side and rear lot lines, and must be 3 m from the house. Your existing garage or shed counts against the same cap.

Oshawa allows a maximum of three units on the lot, with no more than one in an accessory building. So you can have the house, a basement unit and a garden suite, but not two suites in the yard. Good published cost data for Durham garden suites doesn't exist yet. The closest is Toronto, where permits list a [median of $180,000](https://www.toronto.ca/legdocs/mmis/2025/ph/bgrd/backgroundfile-256980.pdf) and the industry told the City real costs often exceed $300,000 to $400,000. See our garden suites page for how we build them.

## What's specific to renovating in Oshawa

These are the Oshawa details that catch people, and that don't apply the same way in Whitby or Ajax:

- **The zoning by-law.** Oshawa works from [Zoning By-law 60-94](https://www.oshawa.ca/business-development/planning-and-development/development-applications/zoning/). Bungalows in the R1-A to R1-E zones get 9.0 m and 40%; larger-lot R1-F to R1-H zones allow 10.5 m.
- **The Committee of Adjustment.** If your plan breaks a zoning rule, five community members appointed by Council hear the [minor variance](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/), for $856 per lot.
- **CLOCA.** If the lot is in a fill-regulated area or floodplain, or the work could affect a watercourse, you need a [Central Lake Ontario Conservation Authority permit](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/) as well. A minor permit for small additions is [$535](https://www.cloca.com/_files/ugd/6cdd05_ca1ea5bbdaa34f3ca770f69ab8f830e4.pdf).
- **The airport.** Near the Oshawa Executive Airport, the City needs [airport clearance](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/) before it issues a permit. That matters most for a second storey.
- **Review times.** Oshawa says record application volumes mean it [cannot guarantee review timeframes](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/). Ontario's Building Code sets [10 business days](https://www.publications.gov.on.ca/301880) for a complete application on a house with no unit above another, and 15 for other small buildings, which can include a house with a basement unit.
- **Building first, permit later.** Oshawa adds a [25% surcharge](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) when work starts after an application is in, and 50% when there's no application at all.

## How we'd approach your bungalow

James comes out first and looks at the whole house: the basement height, the foundation, where the bearing walls run, the lot and the driveway. Often the answer is a mix, like opening the main floor now and roughing in for a basement unit, and it's cheaper to decide that before anything is drawn.

Ceara Jarvis's studio, Juliette Interiors, designs and draws it with us. A licensed engineer stamps the structure. We apply for the permit, the variance if one's needed and the CLOCA permit if the lot is regulated. One crew does the work, we book the inspections, and you get the registration or the closed permit at handover.

Our [projects page](https://www.jarviscontracting.ca/projects) shows finished work, and we're writing up more case studies now. The [Greenwood project](https://www.jarviscontracting.ca/projects/greenwood) was a ten-month renovation in Toronto that we took through permit, design and construction.

## Questions

### Can I add a second floor to my bungalow in Oshawa?

You can add a second floor to most Oshawa bungalows if an engineer confirms the foundation can carry it and the new roof stays under the zoning height. In the R1-A to R1-E zones of By-law 60-94 that height is 9.0 m. Above it, you need a minor variance from the Committee of Adjustment, which costs $856 per lot.

### How much is a building permit for a bungalow renovation in Oshawa?

An Oshawa building permit for a bungalow renovation is charged by floor area as of 2026: $15.56 per m² for an addition or second storey and $7.79 per m² for basement finishing. The minimum fee is $160. A 1,000 sq ft second storey works out to about $1,446.

### How do I make a basement apartment legal in Oshawa?

A basement apartment becomes legal in Oshawa when you build it under a building permit, and the City then issues a two-unit house registration certificate. Units that existed before July 1994 go through Municipal Licensing instead. You'll need one extra parking space for the unit and a basement built to the Building Code's ceiling height and fire separation rules.

### Can I have a basement apartment and a garden suite on the same lot in Oshawa?

You can have both a basement apartment and a garden suite on one Oshawa lot. The City allows up to three units on a lot, with no more than one in an accessory building. The garden suite has to fit within the accessory building limits, including 60 m² of ground floor for all accessory buildings outside the R1-G and R1-H zones.

### Do I need CLOCA approval to renovate my Oshawa bungalow?

You need CLOCA approval for an Oshawa bungalow renovation only when the lot is in a fill-regulated area or floodplain, or the work could affect a watercourse. Interior work like opening a main floor usually isn't affected. Additions and garden suites on regulated lots are, and a minor CLOCA permit is $535.

### Is it cheaper to renovate an Oshawa bungalow than to move?

Whether renovating an Oshawa bungalow beats moving depends on the house and the project, and nobody can answer it without numbers for both. Moving costs commission, legal fees and land transfer tax before you spend anything on the new house; the provincial tax alone on a $1.2 million house is about $20,475, calculated from [Ontario's rates](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax). Our [renovate or move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) sets the two side by side.

# A Narrow Toronto Lot: Renovate, Extend or Rebuild?

By Jarvis Contracting. Published 2026-10-01, updated 2026-10-09.

On a narrow Toronto lot, the first question is what can fit within the property and approval constraints. The second is how the work can actually be built. Compare renovating, extending and rebuilding as separate options before committing to a floor plan.

## Start with the property information

Collect the survey, available house drawings and a list of the changes you need. Confirm the lot dimensions, access routes and existing buildings. Do not use a neighbour's addition as proof that the same design is permitted on your property.

The [City of Toronto building portal](https://www.toronto.ca/services-payments/building-construction/) is the starting point for building and zoning information. Site-specific answers may need a designer, surveyor or the City's review. This article does not assign a setback, permitted height or lot coverage to an unseen property.

## Compare the three paths

| Option | Main question |
|---|---|
| Rework the existing interior | Can circulation, storage and daylight improve inside the current footprint? |
| Add space | Can the structure, site and approvals accommodate a rear extension or another storey? |
| Replace the house | What additional demolition, servicing, licensing and warranty requirements apply? |

New-home construction is a different service from renovating an existing house. Jarvis currently offers additions, renovations and design on this website; it does not currently offer new custom-home construction. Read our [HCRA and Tarion guide](https://www.jarviscontracting.ca/guides/hcra-and-tarion-explained) before comparing builders for a replacement home.

## Plan the route into the site

Limited side access can affect material handling, waste removal, excavation and the order of work. Ask where deliveries can stop, where materials will be stored and how neighbouring property will be protected. Any access agreement should be discussed before assuming that space is available.

Those questions belong in the early scope, not on the morning a large component arrives. The build method has to work with the site as well as with the drawing.

## What Greenwood contributes to the conversation

[Greenwood](https://www.jarviscontracting.ca/projects/greenwood) is a documented Toronto project with a rear extension, replacement top storey and interior work. Its long kitchen and connection to the living space show one way of organising a constrained footprint. Its permissions, dimensions and timeline are not a template for another property.

Bring your survey, photographs and priorities to the [first meeting](https://www.jarviscontracting.ca/contact). We can discuss the renovation and addition options before you decide which direction to investigate in detail.

## Questions

### Does a narrow lot mean I have to add a storey?

No. An interior reconfiguration, rear extension or upper-storey addition may each address different needs. Test them against the site's constraints and the existing structure before selecting a direction.

# Energy-Efficient Homes: What to Compare Before You Build

By Jarvis Contracting. Published 2026-09-30, updated 2026-10-09.

Compare an energy-efficient home proposal by asking what will be designed, installed and checked. A list of efficient products does not explain how the whole house will perform. The envelope, heating and cooling, ventilation and construction details need to be considered together.

## Start with a baseline and a target

For an existing house, ask what information is available about comfort problems, air leakage and energy use. Natural Resources Canada's [EnerGuide information](https://natural-resources.canada.ca/energy-efficiency/product-energy-ratings/energuide/energuide-energy-efficiency-home-evaluations) provides a starting point for understanding home energy evaluations and finding the appropriate programme information.

For a new home, ask which performance target the design team proposes and how it will be verified. Avoid treating a product label or a rendering as proof that the completed house meets a whole-building standard.

## Compare systems and junctions, not just insulation

Ask how the roof, walls, windows and foundation connect. The points where materials meet deserve as much attention as the specification for each material. A large window area changes the balance between daylight, summer heat and winter comfort.

Heating and ventilation should be considered alongside the envelope. Ask who will size the equipment, what design assumptions they use and how the installed system will be commissioned. Keep those responsibilities in the written scope.

## Use a short comparison checklist

- What is the starting condition or proposed performance target?
- Who is responsible for the energy assessment or modelling?
- Which envelope details are included in the drawings?
- What installation checks and tests are planned?
- Who commissions the heating and ventilation equipment?
- What documents will the homeowner receive at handover?

Programme eligibility and rebates can change. Confirm current terms with the programme administrator before including an incentive in your budget; this article promises no grant amount or eligibility.

## Renovation and new construction are different conversations

For an addition or whole-home renovation, the new work has to meet the existing house. Investigate how the proposed changes affect the parts that remain. A new-home project also has its own builder licensing and warranty requirements; the [HCRA explains who needs a licence](https://www.hcraontario.ca/do-i-need-a-licence/).

Jarvis currently offers [renovations](https://www.jarviscontracting.ca/whole-home-renovations), [additions](https://www.jarviscontracting.ca/home-additions) and design, rather than new custom homes. [Contact us](https://www.jarviscontracting.ca/contact) to discuss the scope of an existing-home project, and use the questions above when comparing any proposal.

## Questions

### Does installing efficient equipment make the whole house efficient?

Equipment is one part of the design. The envelope, ventilation, controls, installation quality and household use also matter. Ask how the complete proposal will be assessed and checked.

# Renovation payment schedules in Ontario: what to pay when

By Jarvis Contracting. Published 2026-09-28, updated 2026-10-05.

Ontario recommends you pay a renovation deposit of no more than 10% of the job, and any renovation contract worth more than $50 has to be in writing ([Ontario, Your rights when starting home renovations or repairs, updated 6 Aug 2026](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). After the deposit, tie each payment to a stage you can walk through and the town has inspected, and keep the last payment back until the deficiency list is done. That is the whole idea; the rest of this page is how to set it up.

## Key takeaways

- Ontario recommends a deposit of no more than 10% of the total project cost, as of October 2026 ([Ontario, Guide for home renovation and roofing businesses, updated 25 Sep 2024](https://www.ontario.ca/page/guide-home-renovation-and-roofing-businesses)).
- Any home renovation contract worth more than $50 must be in writing under Ontario law ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- If you sign the contract at home, you get a 10 calendar-day cooling-off period to cancel ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- The final price can't be more than 10% over the original estimate unless you agreed to new work or a new price ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Ontario's guide for renovation businesses says the contract should include a payment schedule that states the deposit amount, plus a work schedule with dates ([Ontario, Guide for home renovation and roofing businesses](https://www.ontario.ca/page/guide-home-renovation-and-roofing-businesses)).

## How much deposit should I pay a contractor in Ontario?

Pay 10% or less. That is the province's recommendation on both its homeowner page and its guide for renovation businesses, and it's the number to hold a contractor to when you sign.

A deposit has a job. It holds your spot in the schedule and pays for things that have to be ordered early: windows, a steel beam, custom cabinets. It shouldn't pay for work that hasn't started, and it shouldn't pay for the contractor's last job.

Homeowners online land all over the place. On RedFlagDeals, one poster suggested [25% at signing](https://forums.redflagdeals.com/large-deposit-contractor-1195058/) (a search snippet, not a thread we could read in full), while another, after a contractor took a deposit and never showed, wrote "never pay more than 100 for deposit!" ([RedFlagDeals, 14 Sep 2020](https://forums.redflagdeals.com/contractor-took-deposit-didnt-show-2403023/)). Ontario's 10% sits between the two, and it's the one with a source behind it.

The cost of getting this wrong is real. In a CTV W5 story, a Brampton owner paid $33,000, about 90% of the contract, for a basement apartment that was still unfinished two and a half years later ([CP24, 9 Jul 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)). The money was gone before the work was.

### What if the contractor asks for a bigger deposit?

Ask what the money buys. If the answer is a special-order item, you have options that keep you covered:

1. Pay the supplier directly for that item, in your name, and have it delivered to the site.
2. Pay for the item when it arrives at the house, as its own line in the payment schedule.
3. Keep the deposit at 10% and move the rest of the money to the first milestone.

If the contractor won't take any of these and still wants a large share before a permit is issued, treat that as your answer. Our [checklist of signs of a bad contractor](https://www.jarviscontracting.ca/post/signs-of-a-bad-contractor-before-you-hire-an-ontario-homeowner-s-checklist) covers the other warnings that usually come with it.

## What should a renovation payment schedule look like?

Each payment should follow a stage you can see and, where the town inspects, a stage the inspector has passed. A schedule tied to proof is easier to check than one tied to dates or to the contractor's word that a phase is nearly done.

Here is an example for a renovation that needs a building permit, such as a rear addition or a basement with new walls and plumbing:

| Stage | What has to be true before you pay | Example share of contract (illustration only) |
|---|---|---|
| Signing | Written contract signed, scope and drawings attached | 10% (Ontario's recommended maximum) |
| Permit issued | Permit card in hand; long-lead items ordered with receipts | 15% |
| Framing | Framing done and the town's framing inspection passed | 20% |
| Rough-ins | Plumbing, HVAC and electrical roughed in and inspected; insulation inspected | 20% |
| Close-in and finishes | Drywall, flooring, cabinets and trim installed | 20% |
| Substantial completion | Final inspection passed; you can use the space | 10% |
| Deficiencies done | Every item on the written deficiency list fixed | 5% |

Note: Only the 10% deposit comes from Ontario's guidance. The other percentages are made up to show the shape of a milestone schedule; they are not a rule and not our own terms. Your contract sets the real numbers and says whether they include HST.

Two things make this work. First, every milestone names a document: a permit, an inspection result, a receipt, a signed deficiency list. Second, the last payments land after the inspector has signed off, so the contractor still has money waiting when the small jobs at the end are the only ones left.

Electrical is inspected separately. In Ontario, a notification of work has to be filed with the Electrical Safety Authority before electrical work starts, and only a licensed electrical contractor can do it ([ESA, Finding the right contractor](https://esasafe.com/compliance/finding-the-right-contractor/)). If the rough-in payment includes electrical, ask to see that the notification was filed.

## Should I pay by milestone or by date?

Pay by milestone on a job with a set scope and price. A calendar schedule pays for weeks going by. If the crew is pulled to another site for a fortnight, a date-based invoice still comes due and you've paid for time, not walls.

Dates make more sense on cost-plus or time-and-materials work, where you're billed for labour and materials as they're used. Then the invoice should show hours, receipts and the markup, and you should be able to match it to what happened on site. Our guide to [fixed price vs cost-plus](https://www.jarviscontracting.ca/guides/fixed-price-vs-cost-plus) goes through when each model fits.

## Should I hold back the final payment?

Yes. Keep the last payment until the deficiency list is finished. This is ordinary practice, not a legal percentage, and the size of it is something you and the contractor agree in the contract.

Here is how it works on a well-run job. Near the end, you walk the house with the contractor and write down everything that isn't right: a door that sticks, a missing outlet cover, a paint touch-up, a tile with a chip. Both of you sign the list and agree a date. The final payment follows when the list is done.

If you want to know whether any legal holdback rules apply to your contract, ask an Ontario lawyer. We build houses; we won't guess at the law for you.

## How do change orders affect what I pay?

Every change goes in writing, with a price, signed by both of you, before the work is done. That protects the 10% rule: the final price can't be more than 10% over the estimate unless you agreed to new work or a new price ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). Ontario's business guide says the customer asks for the extra work and both parties sign a contract change ([Ontario, Guide for home renovation and roofing businesses](https://www.ontario.ca/page/guide-home-renovation-and-roofing-businesses)).

Some changes come from you: a bigger window, a different tile. Others come from the house. Open a wall in an older home and you can find a rotted sill plate, an undersized joist or old wiring that has to come out. That's a change too, and it should be priced and signed before the crew carries on. A change order added to the next milestone keeps the schedule honest: you see the cost when the decision is made, not on the final invoice.

## What should the contract say about payments?

Ontario's guide for renovation businesses lists what a contract should include: the business's details, a description of the work and materials, the total cost and payment terms with taxes, a work schedule with dates, the subcontractors, a payment schedule that states the deposit amount, and who cleans up ([Ontario, Guide for home renovation and roofing businesses](https://www.ontario.ca/page/guide-home-renovation-and-roofing-businesses)).

Pay by cheque or bank transfer so there's a record, and get a receipt for every payment. Keep the receipts with the contract, the permit and your photos. If anything goes wrong later, that file is what you'll lean on.

## What's different in Durham Region?

In Durham Region, Ontario, the town's inspections are your milestones, and the towns publish how they work. The Town of Whitby books an inspection for the next business day if the request comes in by 3 p.m. ([the Town of Whitby's building permits page](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)). A payment tied to "framing inspection passed" shouldn't hold a Whitby job up for long.

Starting work before a permit costs you, not just the contractor. Whitby charges the greater of $100 or 25% of the application fee when work starts before the permit application is in ([Town of Whitby, 2026 Building Services Fees, Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)). Oshawa adds 25% to the permit fee if construction started after an application, and 50% if no application was received ([City of Oshawa, By-law 33-2009 as amended](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf)). So never make a payment for demolition or framing before the permit is issued.

The permit milestone can take a while, so don't let the deposit sit idle and grow. Ontario sets a 10 business day decision period for a complete permit application on a house ([Ontario Building Code](https://www.publications.gov.on.ca/301880)), but Oshawa warns that, with record application volumes, it can't guarantee review timeframes will be met ([the City of Oshawa's building permits page](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/)). If you want to check a permit's status yourself in Whitby, the Building Division is at 905.430.4305 ([the Town of Whitby's building and renovating page](https://www.whitby.ca/services-and-payments/building-and-renovating/)).

## How we set up a job

Every job starts with James at your house, looking at what's there. Ceara Jarvis's studio, Juliette Interiors, does the design and drawings, we take them through the permit, and one crew builds it. We book the inspections and walk the house with you at handover. The payment schedule is written into the contract before any work starts, so you know what each payment is for; ask us at the first visit how ours lines up with the stages above. You can see how a job runs on our [process page](https://www.jarviscontracting.ca/process).

Explore our case studies on the [projects page](https://www.jarviscontracting.ca/projects). The nearest one to this topic is [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), a ten-month renovation in Toronto that we took through permit, design and construction.

## Questions

### How much deposit is normal for a renovation in Ontario?

Ontario recommends a renovation deposit of no more than 10% of the total project cost, as of October 2026. A contractor asking for much more than that should be able to tell you exactly what the extra money buys, such as a special-order window, and you can offer to pay the supplier directly instead.

### Can a contractor ask for 50% upfront in Ontario?

A contractor can ask, but Ontario's guidance is a deposit of no more than 10%. A 50% upfront payment leaves you carrying most of the risk before any work is inspected. In the CTV W5 story from July 2026, a Brampton owner who paid about 90% of the contract was left with an unfinished basement apartment.

### Can a contractor charge more than the estimate in Ontario?

A contractor in Ontario can't charge more than 10% over the original estimate unless you agreed to new work or a new price. Changes should be written down, priced and signed by both of you before the work is done, so the final invoice holds no surprises.

### Can I cancel a renovation contract I signed at home?

A renovation contract signed at your home in Ontario carries a 10 calendar-day cooling-off period. Ontario's business guide says you can cancel for any reason in that time without paying a cancellation fee.

### Should I pay a renovation contractor in cash?

Paying a renovation contractor in cash leaves you without a record of what you paid and when. Pay by cheque or bank transfer, get a receipt for each payment, and keep them with the written contract, which Ontario requires for any renovation worth more than $50.

### What should the final renovation payment depend on?

The final renovation payment should depend on two things: the town's final inspection being passed, and every item on the signed deficiency list being fixed. Holding the last payment until then is common practice; the amount is set in your contract.

# Signs of a bad contractor in Ontario, before you hire

By Jarvis Contracting. Published 2026-09-27, updated 2026-10-05.

The clearest signs of a bad contractor show up before you sign: a big deposit asked for in cash, no written contract, talk of skipping the permit, no business address, and no name for the licensed electrician. Ontario recommends a deposit of no more than 10% and says any renovation contract worth more than $50 must be in writing ([Ontario, Your rights when starting home renovations or repairs, updated 6 Aug 2026](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). One more thing to get right: renovators aren't licensed by the HCRA, so "check their HCRA licence" is the wrong test for a renovation.

## Key takeaways

- Ontario recommends a renovation deposit of no more than 10%, as of October 2026 ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Any home renovation contract worth more than $50 has to be in writing in Ontario ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- A contract you sign at home comes with a 10 calendar-day cooling-off period ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- In a CTV News and Nanos poll, 26.7% of Canadians had paid for renovation work that went unfinished, or knew someone who had ([CP24, 9 Jul 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)).
- WSIB clearance certificates last up to 90 days, so ask for a current one, not an old copy ([WSIB, Clearance certificate policy](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction)).

## What are the biggest red flags before you sign?

Most bad jobs give a warning at the kitchen table. Here are the ones we'd walk away over, and what to ask when you see them:

| Red flag | Why it matters | What to ask or check |
|---|---|---|
| A big deposit, especially in cash | Your money is gone before any work is inspected | Ontario recommends 10% or less; pay by cheque or transfer with a receipt |
| No written contract | You have nothing to hold them to; Ontario requires one over $50 | A contract with scope, price, payment schedule and dates |
| "You don't need a permit for this" | Unpermitted work is uninspected work, and you own the problem | Ask who applies, and what drawings go in |
| No business address, only a cell number | You can't find them if they stop answering | A real address on the contract and the invoice |
| Can't name the electrician | Only licensed electrical contractors may do electrical work in your home | The licensed electrical contractor's name, and that ESA is notified |
| No WSIB clearance certificate | Workers and subcontractors on your job should be covered | A current clearance certificate |
| A price that's only good today | Pressure stops you comparing quotes | Take the 10-day cooling-off seriously if you sign at home |

Note: The rules in this table are Ontario's as of October 2026, with sources linked below. The rest is what we look for on site, not a legal test.

## How much deposit is too much?

Anything much over 10% should get a hard question. Ontario's recommendation is a deposit of no more than 10% of the job, and the stories in the news are what happens past it.

In a CTV W5 investigation, a Brampton owner paid $33,000, about 90% of the contract, for a basement apartment that was still unfinished two and a half years later. "He just disappeared," the owner said ([CP24, 9 Jul 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)). A Mississauga family paid $85,000 for a basement apartment with a separate entrance that was never finished: "We are paying for something we didn't get" ([CP24, 22 May 2025](https://www.cp24.com/local/peel/2025/05/22/ontario-family-says-company-doing-their-basement-renovation-took-85000-and-never-finished-the-work/)).

The pattern in both is the same. Most of the money went in early, and nothing tied the next payment to work you could see. Our guide to [renovation payment schedules](https://www.jarviscontracting.ca/post/home-renovation-payment-schedule-ontario-guide) shows how to set milestones so that can't happen.

Cash makes it worse. A cash deal leaves you no record of what you paid, and a contractor who insists on it is telling you something about how they run the rest of the business.

## Why does the permit question tell you so much?

Because a contractor's answer shows whether they plan to have their work inspected. In Ontario, no one may construct or demolish a building without a permit from the chief building official ([Building Code Act, s. 8](https://www.ontario.ca/laws/statute/92b23)), and the province tells homeowners that getting the permits is their responsibility ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

That last part is where people get caught. The permit is yours, but a contractor can apply on your behalf: Ontario's permit rules accept the owner or an authorized agent as the applicant ([Ontario Building Code](https://www.publications.gov.on.ca/301880)). So the warnings are a contractor who says moving a wall or adding a bathroom "doesn't need one," or one who tells you to apply in your own name and then hands you no drawings to apply with.

A RedFlagDeals thread from Whitby shows how it goes. A family paid $30,000 for a bathroom for elderly relatives and came to suspect the permits had been skipped and the contractor wasn't qualified for a second job ([RedFlagDeals, 1 Apr 2024](https://forums.redflagdeals.com/need-help-dealing-contractor-taking-advantage-elderly-family-durham-region-2684774/)). By the time you're asking strangers online, the work is already behind the drywall.

## Who is doing the electrical and gas work?

A general contractor should be able to name them before you sign. Licensed electrical contractors are the only businesses in Ontario legally allowed to do electrical work in your home, general contractors aren't licensed for it, and a notification of work has to be filed with the Electrical Safety Authority (ESA) before the work starts ([ESA, Finding the right contractor](https://esasafe.com/compliance/finding-the-right-contractor/)). Ontario's homeowner page says you can check a licence in ESA's database.

Gas is the same idea. Installing, altering or removing a gas appliance or piping needs a person who holds a certificate for that work ([O. Reg. 212/01](https://www.ontario.ca/laws/regulation/010212)), and that system runs through the Technical Standards and Safety Authority (TSSA). If the answer to "who's moving the furnace?" is "my guy," ask for his name and his certificate.

## Should my contractor have a WSIB clearance certificate?

Ask for one. The Workplace Safety and Insurance Board (WSIB) requires people who own or run a construction business to have coverage, with some exceptions ([WSIB, Expanded compulsory coverage](https://www.wsib.ca/en/businesses/registration-and-coverage/expanded-compulsory-coverage-construction-industry)). One exception covers an owner-operator doing only home renovation work directly for the person living in the house, but their workers and subcontractors must still be covered ([WSIB, Operational policy](https://www.wsib.ca/en/operational-policy-manual/expanded-compulsory-coverage-construction)).

To be straight about the rule: a homeowner who hires a contractor only for that kind of exempt home renovation work isn't required to get a clearance certificate ([WSIB, Clearance certificate policy](https://www.wsib.ca/en/operational-policy-manual/clearance-certificate-construction)). It's still a fair question. A firm with a crew should be able to produce a current one, and since a certificate lasts up to 90 days, an old copy tells you nothing about today.

## Does my renovator need an HCRA licence?

No. The Home Construction Regulatory Authority (HCRA) licenses people who build and sell new homes. On renovations, HCRA's own words are that "renovators aren't licensed or regulated like new home builders and sellers are" ([HCRA, Finding a renovator](https://www.hcraontario.ca/resources/finding-a-renovator/)). HCRA also says renovations or upgrades to an existing home typically don't make it a new home, so the builder needs no licence ([HCRA, Do I need a licence](https://www.hcraontario.ca/do-i-need-a-licence/)).

Some contractor blogs list a missing HCRA registration as a renovation red flag. For a kitchen, a basement or an addition, that's wrong, and a renovator can't show you a licence that doesn't exist for their work. The same goes for Tarion: its warranties cover new homes, and it excludes "alterations, deletions or additions made by the homeowner" ([Tarion, What is not covered](https://www.tarion.com/homeowners/what-is-not-covered)). Coach houses, laneway homes and tiny homes are the exception to watch: HCRA says they generally need a licensed builder and warranty coverage ([HCRA, Do I need a licence](https://www.hcraontario.ca/do-i-need-a-licence/)). We explain the split in [HCRA and Tarion explained](https://www.jarviscontracting.ca/guides/hcra-and-tarion-explained).

So for a renovation, there's no public register to look your contractor up in. You check them the old way: past jobs you can visit, references you can call, permits on past work, the licensed trades they use, and the contract itself.

## What if they pressure you to sign at the door?

Don't sign that day. If you do sign a renovation contract at home, Ontario gives you a 10 calendar-day cooling-off period, and the province's business guide says you can cancel in that time for any reason without a cancellation fee ([Ontario, Guide for home renovation and roofing businesses, updated 25 Sep 2024](https://www.ontario.ca/page/guide-home-renovation-and-roofing-businesses)).

Pressure is how big losses start. A Toronto couple lost $480,000 on a roofing renovation after being pressured into work that was incomplete and unnecessary ([CTV News Toronto, 8 Jul 2025](https://www.ctvnews.ca/toronto/consumer-alert/article/a-horror-show-toronto-couple-loses-480000-in-botched-roofing-renovation/)). A good contractor's price will still be there next week.

## What to check in Whitby and Oshawa

In Durham Region, Ontario, the towns publish the cost of building without a permit, and a contractor who skips one passes that cost to you. Whitby charges the greater of $100 or 25% of the application fee when work starts before a permit application is made ([Town of Whitby, 2026 Building Services Fees, Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)). Oshawa adds a surcharge of 50% of the permit fee when construction has begun and no application has been received ([City of Oshawa, By-law 33-2009 as amended](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf)).

Basement apartments carry one more Whitby step. On top of the building permit, every additional dwelling unit in Whitby has to be registered with the Town, at $268 ([Town of Whitby, Additional dwelling units](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/)). A contractor offering you a "legal basement" in Whitby who never mentions the permit or the registration probably hasn't built one here.

Finding someone in Durham is harder than it should be. One RFD poster said it plainly: "It's so hard to research them online" ([RedFlagDeals](https://forums.redflagdeals.com/renovation-contractor-durham-2542118/)). The Town of Whitby's Building Division takes calls at 905.430.4305 ([Town of Whitby, Building and renovating](https://www.whitby.ca/services-and-payments/building-and-renovating/)), and the City of Oshawa's building inspectors at 905-436-3311 ([City of Oshawa, Building inspections](https://www.oshawa.ca/living-here/building-and-renovating/building-inspections/)), if you want to ask about permits on your own house.

## How we run the first meeting

James comes to the house first and looks at what's there: the structure, the panel, the plumbing, what's behind the wall you want gone. Before you sign, you'll know who our electrician and plumber are, what the contract covers, and what each payment is for. Then Ceara Jarvis's studio, Juliette Interiors, does the design and the drawings, and we take those drawings through the permit. One crew builds it, we book the inspections, and we walk the house with you at handover.

Ask us every question on our [list of questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor). Explore our case studies on the [projects page](https://www.jarviscontracting.ca/projects), and you can read how a job runs on the [process page](https://www.jarviscontracting.ca/process).

## Questions

### What is the biggest sign of a bad contractor in Ontario?

The biggest sign of a bad contractor in Ontario is a request for a large deposit before any work is inspected, often in cash and often with no written contract. Ontario recommends a deposit of no more than 10% and requires a written contract for any renovation worth more than $50.

### Do renovators in Ontario need an HCRA licence?

Renovators in Ontario don't need an HCRA licence. The Home Construction Regulatory Authority licenses new home builders and sellers, and it says renovators aren't licensed or regulated the way builders are. A missing HCRA licence is not a red flag for a renovation; a missing written contract or permit is.

### Is it a red flag if a contractor asks me to get the permit?

Ontario says getting building permits is the homeowner's responsibility, so a contractor asking you to sign the application isn't wrong in itself. The red flag is a contractor who gives you no drawings to apply with, says the job doesn't need a permit, or wants to start before one is issued.

### How do I check who is doing the electrical work?

Ask the contractor to name the licensed electrical contractor before you sign, then look the licence up in the Electrical Safety Authority's database. In Ontario, only licensed electrical contractors may do electrical work in your home, and the work has to be notified to ESA before it starts.

### Is asking for cash a sign of a bad contractor?

A contractor who insists on cash is a warning sign, because a cash payment leaves you without a record of what you paid. Pay by cheque or bank transfer, get a receipt every time, and keep the receipts with your written contract.

### Can I cancel if a contractor pressured me into signing at home?

A renovation contract signed at your home in Ontario has a 10 calendar-day cooling-off period. Ontario's guide for renovation businesses says you can cancel in that time for any reason without paying a cancellation fee.

# Mudroom Ideas: A Better Place for Boots, Bags and Daily Life

By Jarvis Contracting. Published 2026-09-25, updated 2026-10-09.

A useful mudroom starts with the route through the house. Find where wet boots, coats, school bags and shopping actually arrive, then give each of them a place without blocking the door. You may be able to create that space within the existing floor plan before considering an addition.

## Plan the arrival before the cabinetry

Walk through a typical busy arrival with the people who live in the house. Check the swing of the exterior door and nearby interior doors. Decide where someone can sit, where a bag can be dropped and how another person gets past.

Measure the objects, too: a vacuum, tall boots, sports equipment and a stroller do not fit the same cupboard. Closed doors make storage visually quiet, while a few open hooks are useful for the coat that is worn every day.

## What Bellamy shows

The [Bellamy mudroom](https://www.jarviscontracting.ca/projects/bellamy) combines sage-green cabinetry with an oak-lined bench and hooks. The bench provides a distinct landing place within the built-in storage. Its photographs show how the cabinet run, seat and floor meet, rather than presenting a generic locker drawing.

Borrow the principle, not the dimensions. Your entry may need a shorter bench, fewer compartments or a different relationship to the kitchen. A good layout responds to the doorway and the household.

## Compare three ways to make space

| Approach | What to investigate |
|---|---|
| Rework an existing entry | Door swings, bench depth and everyday circulation |
| Borrow adjacent space | What the neighbouring room loses and how light changes |
| Add a new room | Exterior connection, roof, structure, services and approvals |

A mudroom addition is a building project, not just cabinetry outside the current wall. Review the whole scope through our [home-additions service](https://www.jarviscontracting.ca/home-additions) before comparing it with an interior refit.

## Design for wet and dirty items

Separate temporary wet storage from longer-term closed storage. Ask about washable surfaces, easy-to-clean junctions, boot trays and the drying arrangement before choosing the cabinet finish. Keep electrical equipment and charging locations away from where water collects.

Make a simple brief for the first meeting: photographs of the entry, a list of what needs storage, what is most frustrating now and whether the adjacent rooms can change. The first conversation is more useful when it begins with the routine you want to improve.

## Questions

### Do I need an addition to get a mudroom?

Not necessarily. Start by testing the existing entry and adjacent storage against the things you need to keep there. An addition becomes one option when the current footprint cannot accommodate the circulation and storage you need.

# An Open-Concept Kitchen in Pickering: What to Plan First

By Jarvis Contracting. Published 2026-09-24, updated 2026-10-09.

Before opening a Pickering kitchen to the next room, find out what the dividing wall carries and what runs through it. Then test the furniture, storage and circulation in the combined space. Removing a wall can solve one problem while creating another if the new room has nowhere for the everyday things to go.

## Understand the wall before drawing the island

A wall can contain wiring, plumbing or ductwork as well as support the structure above. Arrange an assessment of the existing conditions before assuming that it can disappear. The structural solution may introduce a beam or posts that need to be incorporated into the design.

Start the approval conversation with the [City of Pickering](https://www.pickering.ca/) building department. Describe the proposed structural and service changes rather than asking only whether a kitchen renovation needs a permit. Our Pickering guide collects the local planning references.

## Design the whole connected room

Draw the kitchen, dining table and seating together. Show doors open, chairs pulled out and people passing behind stools. Check where a television, tall pantry or coat storage can go once there is less wall area.

Think about light and sound as well. A single open space shares cooking noise and sightlines. Sometimes a wider opening or a partial division gives the household a better balance than removing every boundary.

## Use Bellamy as a structural example, not a local claim

[Bellamy](https://www.jarviscontracting.ca/projects/bellamy) is in Scarborough, not Pickering. Its case study records the removal of load-bearing walls, steel beams and a coordinated main-floor renovation. It is relevant as an example of the decisions involved, without claiming it as a Pickering project.

The finished photographs also show storage, flooring and the connection to an office. Those details matter because the area exposed by a removed wall has to become part of a complete room.

## Compare proposals on matching scope

Ask each proposal to identify structural work, electrical and plumbing changes, floor repairs, cabinetry, finishes, approvals and exclusions. A low cabinet price does not describe the cost of opening the main floor.

Bring photographs of the kitchen and the rooms above and below it to the first discussion. If you have drawings, keep them available. Our [kitchen service](https://www.jarviscontracting.ca/kitchen-renovations) explains the wider scope, and [James can review your plans](https://www.jarviscontracting.ca/contact) with you.

## Questions

### Can I remove a kitchen wall without a visible beam?

That depends on the structure and the available depth above the ceiling. Have the existing conditions assessed before choosing a flush ceiling as a fixed design requirement.

# Planning a Multigenerational Home Addition in Ontario

By Jarvis Contracting. Published 2026-09-22, updated 2026-10-13.

There are three ways to house a parent or adult child on your lot in Ontario: an in-law suite that stays part of your home, a legal second unit inside the house, or a garden suite in the yard. Ontario's [Planning Act](https://www.ontario.ca/laws/statute/90p13) lets you have up to three units on most urban lots as of right, and as of October 2026 Whitby caps a detached unit at 75 m² of floor area and 4.5 m tall under [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf). Which one fits depends on how independent the household needs to be, and on the money.

## Key takeaways

- Ontario's [Planning Act](https://www.ontario.ca/laws/statute/90p13) stops municipalities from banning three units on an urban residential lot: three in the house, or two in the house and one in a building in the yard.
- The federal [Multigenerational Home Renovation Tax Credit](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc.html) is 14.5% of up to $50,000 in costs, a maximum of $7,250, for a secondary unit with its own entrance, kitchen, bathroom and sleeping area.
- Whitby limits a detached additional dwelling unit to 75 m² of floor area and 4.5 m in height under [Zoning By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf), while Oshawa caps accessory buildings at 60 m² of ground floor in most zones, per its [accessory apartments page](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/).
- In 2021, 9.7% of people in the Oshawa area lived in multigenerational households, against 11.6% in the Toronto area, according to [Statistics Canada](https://www150.statcan.gc.ca/n1/pub/91f0015m/91f0015m2025003-eng.htm).
- Toronto garden suite permits list a median cost of $180,000 and an average of about $260,000, and builders told the City real costs often pass $300,000 to $400,000, per the [Toronto's May 2025 garden suites report](https://www.toronto.ca/legdocs/mmis/2025/ph/bgrd/backgroundfile-256980.pdf).

## Which option fits your family?

The right option depends on how much independence each household needs.

Here is how the three options compare on rules and money:

| | In-law suite (part of your home) | Legal second unit in the house | Garden suite in the yard |
|---|---|---|---|
| What it is | Bedroom, bathroom and sitting room added to your home, sharing the kitchen or front door | A self-contained unit with its own kitchen, bathroom and entrance, in a basement, an addition or an upper floor | A self-contained unit in its own building behind the house |
| Counts as a separate dwelling unit | No | Yes | Yes |
| Fire separation between households | Not needed for one dwelling | Needed, per the [Ontario Building Code](https://www.publications.gov.on.ca/301880) | Separate building |
| Federal multigenerational tax credit | No: the credit needs a self-contained unit | Can qualify | Can qualify |
| Cost range | Our 2026 range: $180,000 to $450,000 for a 300 to 700 sq ft single-storey rear addition | Our 2026 range: $45,000 to $95,000 to legalise a finished basement; $80,000 to $180,000 for a full legal basement apartment | $180,000 median, about $260,000 average by Toronto permit value ([Toronto permit data](https://www.toronto.ca/legdocs/mmis/2025/ph/bgrd/backgroundfile-256980.pdf)) |

Note: the first two cost ranges are our own for 2026, before 13% HST, and aren't a quote. The garden suite figures are Toronto permit values (2022 to April 2025), which the City says likely understate real costs.

An in-law suite on the main floor suits a parent who needs help nearby, and since it only enlarges your home, it adds no dwelling unit. A legal unit or a garden suite gives each household its own door, with more rules and a bigger bill.

## What changes when an in-law suite becomes a legal unit?

The line is the kitchen and the door. Once the space is a self-contained home, with its own cooking, bathroom and sleeping areas behind its own entrance, the building department treats it as a second dwelling unit, and a different set of rules applies.

The [Ontario Building Code](https://www.publications.gov.on.ca/301880) defines a secondary suite as a self-contained dwelling unit in a residential building with only one other dwelling unit. For a house with a secondary suite, the Code sets out:

- **Fire separation.** Walls and the floor-ceiling between the units need a fire separation. The Code allows a continuous smoke-tight barrier of 15.9 mm Type X gypsum board in place of a 45-minute rated assembly, and the rating can be waived if the house is sprinklered.
- **Ceiling height.** At least 1.95 m in the suite, and at least 1.85 m clear under beams and ductwork. Older basements often fail this one, which is when underpinning or lowering the floor enters the budget.

Turning part of a house into a second suite is also a change of use, which needs a permit under the [Building Code Act](https://www.ontario.ca/laws/statute/92b23) even where little construction happens.

Two provincial rules make the legal route easier. Zoning can't require more than one parking space for each added unit, and can't set a minimum floor area for it ([Planning Act](https://www.ontario.ca/laws/statute/90p13)). Under [O. Reg. 299/19](https://www.ontario.ca/laws/regulation/190299), anyone may live in an additional unit, related or not, so a suite built for your mother today can be rented to someone else later. Our guide to [Bill 23 and additional units](https://www.jarviscontracting.ca/guides/bill-23-additional-units-ontario) goes through the provincial rules in full, and the [legal basement apartment guide](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario) covers the basement route.

## What does each option cost?

The spread in basement suite prices above is mostly underpinning, the entrance and the size. In our 2026 ranges, a separate side entrance runs $18,000 to $28,000 and underpinning the full perimeter $60,000 to $120,000. Our permit drawings run $4,000 to $8,000 for a basement apartment, $6,000 to $12,000 for an addition and $5,000 to $15,000 for a garden suite. Those prices cover drawings only: permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen are extra.

Garden suites cost the most: builders interviewed for [Toronto's May 2025 garden suites report](https://www.toronto.ca/legdocs/mmis/2025/ph/bgrd/backgroundfile-256980.pdf) said real costs often exceed $300,000 to $400,000.

## Money that comes back: the tax credit and development charges

Two things reduce the bill for a self-contained family unit. The first is the federal [Multigenerational Home Renovation Tax Credit](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc.html). It's a refundable credit of 14.5% of up to $50,000 in eligible costs (for the 2025 tax year), a maximum of $7,250 per qualifying renovation. The unit has to be self-contained, with its own entrance, kitchen, bathroom and sleeping area, and it has to be built so a senior, or an adult eligible for the disability tax credit, can live with a qualifying relative. Check your own case against the CRA page before you count on it.

The second is development charges, which a new unit would otherwise attract. Under the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27), no development charges apply to a second or third unit in an existing house, or to one unit in a building in the yard, within the three-unit limit. Enlarging your own home with an addition doesn't trigger them either.

## Financing a family suite

Plan the financing before the drawings. Toronto's [garden suites report](https://www.toronto.ca/legdocs/mmis/2025/ph/bgrd/backgroundfile-256980.pdf) found financing was a major barrier for garden suites: there are no resale comparables for an appraiser to use, so many owners refinance the main house, and some abandon the project.

The same report found most Toronto garden suites house family, and rent alone often doesn't cover the cost. Talk to your lender with a rough budget first.

## Designing for a parent who will age there

Put the bedroom and a full bathroom on the ground floor if a parent is going to live there for the long term. On a Houzz thread about adding a second floor, one reply flagged the new stairs, "which isn't great for aging in place" ([Houzz, about 2014](https://www.houzz.com/discussions/935249/add-a-second-floor-or-move)), and suggested keeping a bedroom and bath on the main floor.

That points most multigenerational projects toward a rear addition on the main floor, or a garden suite, rather than a second storey. Inside, the details that matter cost little at framing stage and a lot later: wider doors, a shower without a curb, blocking in the walls for grab bars, a bathroom big enough to turn around in, lever handles, and good light on the path to the door.

## The rules in Whitby, Oshawa and Durham Region

In Durham Region, each town writes its own unit rules on top of the provincial ones, and as of October 2026 Whitby and Oshawa differ in ways that change the design:

- **Whitby size and setbacks.** A detached additional dwelling unit can be up to 75 m² of floor area and 4.5 m tall, set back at least 1.2 m from the interior side and rear lot lines and 3.0 m from an exterior side line ([By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf)). The entrance needs an unobstructed path at least 1.2 m wide and 2.1 m high. Lots on the Oak Ridges Moraine or in the Greenbelt are limited to one additional unit.
- **Whitby registration and fees.** Every unit must be registered with the Town under [By-law 8156-25](https://www.whitby.ca/media/hezdoc2o/8156-25-additional-dwelling-unit-registration-by-law.pdf), on top of the building permit, and registration costs [$268](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/). The permit fee for unit alterations inside a house is $10.65 per m² ([2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)).
- **Whitby charges and incentive.** Town and Region development charges don't apply to a unit in an existing home, but education development charges still apply to detached units and to units in homes occupied for less than 12 months, per the [Town's ADU page](https://www.whitby.ca/services-and-payments/building-and-renovating/additional-dwelling-units/). The Town's ADU Incentive Program reimburses select fees if the complete application is in by 31 December 2026 and the unit is registered by 31 March 2027; see our [Whitby ADU incentive guide](https://www.jarviscontracting.ca/guides/whitby-adu-incentive).
- **Oshawa.** A lot can have up to three units, at most one in an accessory building. Accessory buildings face three caps, 8% of the lot area, 50% of the house's coverage and 60 m² of ground floor (90 m² in R1-G and R1-H zones), and can be 4.5 m tall, at least 3 m from the house. Each unit needs one extra parking space, and the permit comes with a two-unit house registration ([Oshawa accessory apartments](https://www.oshawa.ca/living-here/building-and-renovating/accessory-apartments/)). Oshawa issued 338 of those registrations in 2024 ([Oshawa open data](https://www.arcgis.com/sharing/rest/content/items/97d92126eeae4430885d6225df0ff2a0/data)).
- **CLOCA.** Both towns sit in the Central Lake Ontario Conservation Authority's area. On a lot near a creek, wetland or the lake shore, an additional dwelling unit also needs a [CLOCA permit](https://www.cloca.com/inquiries-permits).

Durham Region issued permits for 999 additional residential units in 2024 and 1,004 in 2025, according to its [2025 building activity review](https://media-003-ca.cdn.govstack.com/durham-ca/media/vc5lqmuu/2026-info-54-2025-annual-building-activity-review.pdf), so a second unit is a routine application here.

## How we'd plan it with you

We start at the house. James walks the lot, the basement and the main floor with you, and with whoever is moving in, because their needs set the plan, and we look at what each option would trigger.

Ceara Jarvis and her studio, Juliette Interiors, then design and draw it, a licensed engineer stamps the structure, and we apply for the permit and the town's registration. One crew builds it, we book the inspections as each stage is ready, and we hand it over. For the building itself, see our [home additions](https://www.jarviscontracting.ca/home-additions) and garden suites pages.

Explore our case studies on our [projects page](https://www.jarviscontracting.ca/projects); the first, [Greenwood](https://www.jarviscontracting.ca/projects/greenwood), was a ten-month renovation in Toronto that we took through design, permit and construction.

## Questions

### Is an in-law suite the same as a legal secondary suite in Ontario?

An in-law suite and a legal secondary suite are different things in Ontario. An in-law suite that shares the main kitchen or entrance is part of your home, so it is one dwelling unit and needs no fire separation between households.

A secondary suite is a self-contained dwelling unit with its own kitchen, bathroom and entrance. The Ontario Building Code sets fire separation and ceiling height rules for it, and towns like Whitby require it to be registered.

### Can I build a garden suite for my parents in Whitby?

Whitby's Zoning By-law 1784 allows a garden suite, which it calls a detached additional dwelling unit, on urban residential lots zoned for houses. It can be up to 75 m² of floor area and 4.5 m tall, set back 1.2 m from the interior side and rear lot lines.

A Whitby garden suite needs a building permit and registration with the Town, which costs $268.

### Who qualifies for the Multigenerational Home Renovation Tax Credit?

The Multigenerational Home Renovation Tax Credit covers a renovation that creates a self-contained secondary unit so a senior, or an adult eligible for the disability tax credit, can live with a qualifying relative. The unit needs its own entrance, kitchen, bathroom and sleeping area. The credit is 14.5% of up to $50,000 in eligible costs, a maximum of $7,250 per qualifying renovation, according to the Canada Revenue Agency.

### Do I pay development charges for an in-law suite in Durham Region?

In most cases you don't pay development charges for an in-law suite in Durham Region. The Development Charges Act exempts a second or third unit in an existing house and one unit in a building in the yard, and an addition that only enlarges your home doesn't trigger them.

In Whitby, education development charges can still apply to a detached unit, or to a unit in a home occupied for less than 12 months.

# Cost to Build a House in Toronto: Planning the Complete Budget

By Jarvis Contracting. Published 2026-09-21, updated 2026-10-09.

A complete Toronto house-building budget includes more than the construction price. Separate the land, design and approvals, site preparation, servicing, building work, taxes and financing costs before comparing proposals. A price per square foot is useful only when the included work and measured floor area are clear.

## Build the budget in layers

| Budget layer | Questions for the proposal |
|---|---|
| Property | Is land already owned? What acquisition costs are outside the build? |
| Design and investigations | Which surveys, drawings, engineering and site investigations are included? |
| Approvals | Who checks zoning, prepares applications and pays the applicable fees? |
| Site and services | What is allowed for demolition, access, utility connections and ground conditions? |
| Construction | Does the price cover the complete specified house or only selected stages? |
| Completion | Are landscaping, driveways, appliances and final documents included? |
| Owner's costs | What are the implications for temporary housing, financing and insurance? |

Put an amount, an allowance or an explicit unresolved item beside every line. An empty line is not evidence that the cost is included. Ask who will obtain the information needed to replace an allowance with a defined scope.

## Make square-foot figures comparable

Check whether both proposals measure the same area. Ask how they treat basements, garages, porches, double-height spaces and exterior work. A smaller house can still need substantial site preparation and servicing, so dividing one total by floor area does not make every project comparable.

Ask for the date and scope behind any published benchmark. This guide deliberately does not turn a generic market range into a quote for an unseen property. A project-specific budget requires a site, a design brief and a clear set of inclusions.

## Confirm the current municipal items

Use the [City of Toronto building and construction information](https://www.toronto.ca/services-payments/building-construction/) to identify the relevant approval process. Ask the design team which current fee schedules, servicing requirements and other municipal charges apply to your proposal. An earlier project's fees do not establish the fees for a different application.

If the site is constrained, work through access and construction sequencing before pricing. Our [narrow-lot planning article](https://www.jarviscontracting.ca/post/building-on-a-narrow-lot-in-toronto-design-options-constraints-and-next-steps) explains the questions that arise before choosing a floor plan.

## Choose the right service for the decision

A replacement house and a renovation of the existing house are different projects. Verify a proposed new-home builder through the [Ontario Builder Directory](https://obd.hcraontario.ca/) and review the [HCRA's guidance](https://www.hcraontario.ca/do-i-need-a-licence/) before signing.

Jarvis currently offers renovations, additions and design, not new custom-home construction. If you are weighing improvements to your current house against a move or rebuild, the [renovate-or-move guide](https://www.jarviscontracting.ca/guides/renovate-or-move) helps organise that comparison. The renovation figures on our pricing page should not be presented as prices for a new house.

## Questions

### Is land included in a builder's square-foot price?

Do not assume it is. Ask for written inclusions and exclusions, including land, demolition, services, approvals, taxes and exterior work, before comparing the price with another proposal.

### Can I use a renovation quote to estimate a replacement house?

Not reliably. The starting conditions, scope, approvals and warranty arrangements differ. Compare each option using its own complete budget.

# A Design-Build Timeline: What Happens Before Construction

By Jarvis Contracting. Published 2026-09-20, updated 2026-10-09.

A design-build timeline has two different clocks: preparation before the site starts, and construction after it starts. Ask which one a quoted duration describes. A construction estimate does not automatically include design revisions, approvals, product lead times or work needed before the permit application is complete.

## Start with the decisions that unlock the next stage

The first stage defines the problem: which rooms do not work, what space is needed and what can reasonably change. Measured information and a design brief come before detailed finishes.

Next, the layout has to settle enough for structural, mechanical and permit work to proceed. Choosing appliances after the cabinets have been ordered can reopen a decision that appeared finished. A useful schedule shows these dependencies, not just a row of dates.

## Ask for milestones, not one finish date

| Milestone | What to agree |
|---|---|
| Scope and concept | Rooms, priorities and the working budget |
| Design decisions | Layout, major fixtures and structural approach |
| Permit package | Who prepares, submits and answers questions |
| Procurement | Which products must be ordered before site work |
| Construction | Sequence, inspections and access arrangements |
| Handover | Deficiency list, documents and warranty information |

A milestone is useful when it has a clear completion condition. 'Kitchen design complete' should mean an agreed drawing and selections, not simply that a meeting took place.

## Two Jarvis projects, two different clocks

[Greenwood](https://www.jarviscontracting.ca/projects/greenwood) took about ten months including design and permits. Its scope included a new top storey, rear extension and interior work. [West Lynde](https://www.jarviscontracting.ca/projects/west-lynde) involved about four and a half months on site to take a bungalow to two storeys. Those durations describe different scopes and starting points; neither is a promise for another house.

Use the cases to ask better questions: what was included before the site opened, what information was available, and which part of the work controlled the completion date?

## Build a schedule you can use at home

Record when the kitchen or bathroom becomes unavailable, whether the house can be occupied during each phase, where belongings will be stored and who needs access. Ask what would happen if a key item arrived late.

At each update, distinguish a changed sequence from a changed finish date. Some tasks can be reordered; others depend on an inspection or a delivered component. Start with our [project process](https://www.jarviscontracting.ca/process), then [talk to James](https://www.jarviscontracting.ca/contact) about the actual scope of your home.

## Questions

### Can I get a firm timeline before the design is complete?

You can discuss an initial sequence and likely constraints, but a detailed programme needs a settled scope and a clearer view of approvals, products and site conditions. Ask what assumptions the estimate depends on.

# Kitchen Renovation Cost in Ontario: 2026 Budget Guide

By Jarvis Contracting. Published 2026-09-17, updated 2026-10-13.

A mid-range kitchen renovation costs $40,000 to $75,000 in our 2026 range, and a premium one $85,000 to $150,000, both before 13% HST. Where your kitchen lands depends mostly on whether the layout stays, which cabinets you choose and what the walls are hiding. James prices your own kitchen after he has seen it.

## Key takeaways

- Our 2026 range for a mid-range kitchen renovation is $40,000 to $75,000 before HST, and $85,000 to $150,000 for a premium one.
- A GTA homeowner on [RedFlagDeals](https://forums.redflagdeals.com/kitchen-renovation-cost-sanity-check-2439644/) called kitchen quotes of about $65,000 to $70,000 "sticker shock"; we could only read that thread as a search snippet, so treat it as a signal, not data.
- Ontario's [13% HST](https://www.ontario.ca/page/ontario-new-home-affordability-payment) sits on top of most published kitchen ranges, ours included, so check whether a quote shows it.
- The Town of Whitby charges [$10.65 per square metre for interior alterations, with a $305 minimum](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) as of 1 January 2026, so a kitchen under about 28 square metres pays the minimum (our arithmetic).
- Electrical work in an Ontario kitchen has to be done by a licensed electrical contractor, who files a [notification of work with the Electrical Safety Authority](https://esasafe.com/compliance/finding-the-right-contractor/) before starting.

## What does a kitchen renovation cost in Ontario in 2026?

We price kitchens in two tiers, and the section below on what makes a kitchen cost more explains what moves a job from one to the other. Here are our 2026 ranges, with one homeowner's quotes for comparison:

| Kitchen | Range | Basis |
|---|---|---|
| Mid-range renovation | $40,000 to $75,000 | Our 2026 range |
| Premium renovation | $85,000 to $150,000 | Our 2026 range |
| One GTA homeowner's quotes | about $65,000 to $70,000 | [RedFlagDeals thread](https://forums.redflagdeals.com/kitchen-renovation-cost-sanity-check-2439644/), undated |

Note: our ranges are before 13% HST and aren't a quote: James prices your kitchen after he has seen it, and the contract is a fixed price. The forum figure is one owner's post, read from a search snippet, so check any quote you get for whether HST is in.

The forum thread is worth reading for one more reason. Posters there argued that a general contractor's markup on each trade can push a kitchen price up a long way. We only saw that thread through search results, so we can't vouch for the numbers, but the worry is a fair one: ask any builder to show you what the trades cost and what sits on top.

## Why do "mid-range" and "high-end" mean different things at different firms?

Tier labels are marketing, not a standard. Every builder draws the line between mid-range and high-end in its own place, so one firm's high-end can be another's mid-range. Neither is wrong: they sell different kitchens to different buyers.

So compare scope, not labels. When two quotes land far apart, line them up on these questions:

- Is the layout staying, or are the sink, range and walls moving?
- Are the cabinets stock, semi-custom or built to the room?
- Are appliances in the price, or are you buying them?
- Does the price include the permit, the design and drawings, disposal and HST?
- What happens if the wall comes down and the floor underneath doesn't line up?

Ontario's rules help you hold a builder to the number once you have it. On a written estimate, [the final price can't exceed the estimate by more than 10%](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) unless you agree to the changes, and the province recommends a deposit of no more than 10%.

## What makes a kitchen cost more?

The biggest driver is whether the room keeps its bones. A kitchen that keeps its layout, with new cabinets, counters and appliances in the same spots, is a finish job. A kitchen that moves things is a construction job.

**Moving the sink or dishwasher.** A drain needs slope back to the stack. Move the sink to an island and the new line may have to run through or under the floor joists, which means opening the ceiling below. Each new fixture is also a line on the permit: Whitby charges [$27.80 per plumbing fixture](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf).

**Removing a wall.** A kitchen wall may carry structural loads or contain services; its role needs to be checked before removal. When a load-bearing wall comes out, an engineer sizes a beam to replace it, steel or engineered lumber, and the posts at each end carry a point load that has to land on something solid, sometimes a new footing in the basement. Then the floor and ceiling where the wall stood get patched, and two old floors rarely meet at the same height.

**The electrical panel.** An induction range, a wall oven and the counter circuits a modern kitchen needs can outrun an older panel. If the panel is full, it gets replaced or upgraded before the kitchen circuits go in.

**Gas.** Moving a gas range means moving the gas line, which only a [TSSA certificate holder](https://www.ontario.ca/laws/regulation/010212) can do.

**Cabinetry.** This is where the tiers split. Stock boxes, semi-custom lines and cabinets built to the room are different products, and panelled fronts for integrated appliances add more.

**Appliances.** Pick them before the cabinets are drawn. A pro range or a panel-ready fridge sets the cabinet dimensions around it.

**What's behind the walls.** In an older house, opening a kitchen wall can turn up old wiring, old supply pipes or no insulation at all. You don't know until it's open, so a sensible budget keeps room for it.

**HST.** At [13%](https://www.ontario.ca/page/ontario-new-home-affordability-payment), it's the line people forget when they compare a quote to a published range.

## What's different about a kitchen in Durham Region?

The permit rules come from the same province-wide law, but the fees, the heritage districts and the people who sign off are local. Here's what's true in Whitby and Oshawa as of October 2026:

**When you need a permit.** Ontario's Building Code Act says [no one may construct or demolish a building without a permit](https://www.ontario.ca/laws/statute/92b23). In practice, swapping cabinets and counters in place usually doesn't need one. Taking out or moving a wall, cutting into structure, or adding or moving plumbing does. The [Town of Whitby building division](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/) makes the call on your house, so ask before demolition starts.

**What it costs.** Whitby's 2026 schedule charges [$10.65 per square metre for residential alterations and a $305 minimum](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf). Oshawa's building by-law sets a [$160 minimum and $27 per plumbing fixture in a house](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf), with fees effective 1 January 2026. Oshawa also adds a [surcharge of 25% to 50% of the permit fee](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) when work starts without one.

**How long it takes.** Under the Building Code, a town has [10 business days to decide a complete permit application for a house](https://www.publications.gov.on.ca/301880). Once the permit is issued, Whitby books an inspection for the [next business day if you ask by 3 p.m.](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)

**Heritage districts.** Whitby has [two heritage conservation districts](https://www.whitby.ca/explore-and-enjoy/heritage/), Werden's Plan in downtown Whitby and downtown Brooklin. Under the Ontario Heritage Act, a district permit covers [changes to anything other than the interior](https://www.ontario.ca/laws/statute/90o18), so the kitchen itself is yours to change. A new window or back door on that kitchen is not, and needs a heritage permit, which Whitby [doesn't charge for](https://www.whitby.ca/services-and-payments/building-and-renovating/heritage-permits/).

**Electrical and gas.** The [ESA notification](https://esasafe.com/compliance/finding-the-right-contractor/) and the [TSSA certificate](https://www.ontario.ca/laws/regulation/010212) rules are the same in every Ontario town, and they apply even when no building permit does.

## How we'd handle your kitchen

We start with a visit. James comes to the house, looks at the room, the panel and the basement ceiling under the kitchen, and tells you what's simple and what isn't, with a rough estimate on the spot. If it works for you, he prices the whole job in a detailed proposal, and you sign the contract before design starts. Then Ceara Jarvis and her studio, Juliette Interiors, design the layout, the cabinets and the finishes with you, and we draw it.

If a wall is coming out, a licensed engineer sizes the beam and stamps it, and the drawings go in for the permit. One crew does the work. We book the inspections as each stage closes up, and we hand the kitchen back when it's done and signed off by the town.

Our [pricing page](https://www.jarviscontracting.ca/pricing) explains how we price. Our [projects](https://www.jarviscontracting.ca/projects) page has our work; the case studies include photographs and project details.

## Questions

### Is a $30,000 kitchen renovation realistic in Ontario in 2026?

A $30,000 kitchen renovation in Ontario sits below our 2026 mid-range of $40,000 to $75,000 before HST, so it only works if the layout stays put. At $30,000 you're replacing cabinets, counters and fixtures in place, not moving walls or plumbing.

### How much does it cost to remove a load-bearing wall in a kitchen?

We don't publish a price for removing a load-bearing kitchen wall, and we won't guess one. The cost depends on the beam size the engineer calls for, whether the posts need new footings, what runs through the wall (ducts, pipes, wiring) and how much floor and ceiling has to be patched. Someone has to see the wall before anyone can price it.

### Do I need a permit for a kitchen renovation in Whitby or Oshawa?

A kitchen renovation in Whitby or Oshawa needs a building permit when walls, structure or plumbing move, because Ontario law requires a permit to [construct or demolish](https://www.ontario.ca/laws/statute/92b23). Replacing cabinets and counters in the same spots usually doesn't. Electrical work needs an [ESA notification](https://esasafe.com/compliance/finding-the-right-contractor/) either way.

### Can we live in the house during a kitchen renovation?

Most families live at home through a kitchen renovation. We set up a temporary kitchen somewhere else in the house, seal the work area against dust, and keep a clear path in and out. The hard weeks are the ones with no water at the sink, so plan meals around them.

### Is a kitchen renovation price fixed once the contract is signed?

With us, yes. We price the whole kitchen renovation and you sign a fixed-price contract, with a 10% deposit, before design begins. If you change the scope or a selection after that, the change goes through a change order you sign.

### Is design-build cheaper than hiring a designer and a contractor separately?

Design-build isn't automatically cheaper, but it closes the gap between what's drawn and what's priced. When the same team designs and builds the kitchen, the people drawing it know what it costs, so you don't fall in love with a plan that comes back over budget at tender. Our guide to [design-build versus a general contractor](https://www.jarviscontracting.ca/guides/design-build-vs-general-contractor) goes through the trade-offs.

# Firing a contractor mid-project in Ontario: what to do

By Jarvis Contracting. Published 2026-09-10, updated 2026-10-05.

If your contractor has stalled or walked off the job, stop paying, read the contract, photograph and file everything, and put your complaint in writing before anyone else touches the house. Then call your town's building department, because the permit and its inspection record are tied to your address, and the next contractor has to pick up from them. Measure the old contractor against Ontario's rules as of October 2026: a written contract for any job over $50 and a final price no more than 10% over the estimate without agreed changes ([Ontario, Your rights when starting home renovations or repairs, updated 6 Aug 2026](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).

## Key takeaways

- In a CTV News and Nanos poll, 26.7% of Canadians had paid for renovation work that went unfinished, or knew someone who had ([CP24, 9 Jul 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)).
- Any home renovation contract worth more than $50 must be in writing in Ontario ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- The final price can't be more than 10% over the original estimate unless you agreed to new work or a new price ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)).
- Changing the drawings on an open permit costs a town fee too: Pickering lists $180 for a revision to a house permit ([City of Pickering, 2026 fee schedule](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING)).
- The Town of Whitby books an inspection for the next business day when the request is in by 3 p.m. ([Town of Whitby building permits page](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)).

## Step 1: Read the contract before you say anything

Start with what you signed. Find the scope, the price, the payment schedule, the dates and anything about ending the contract. Ontario's guide for renovation businesses says a contract should include a work schedule with dates, a payment schedule that states the deposit, and the subcontractors on the job ([Ontario, Guide for home renovation and roofing businesses, updated 25 Sep 2024](https://www.ontario.ca/page/guide-home-renovation-and-roofing-businesses)). Missed dates and skipped milestones are your evidence, so mark every one.

If there's no written contract at all, that is already outside Ontario's rule for any job over $50. It doesn't make the problem go away, but it changes the conversation.

We're builders, not lawyers. If a lot of money is at stake, or the contract says something you don't understand about ending it, talk to an Ontario lawyer before you send anything.

## Step 2: Document everything

Before you change the locks, move materials or let anyone else in, record the house as it stands. The next contractor, the town and anyone you complain to will all ask for the same things.

Here is what to collect and why the next contractor will ask for it:

| What to collect | Where it usually is | Why it matters |
|---|---|---|
| Dated photos of every room, inside open walls and ceilings | Your phone | Shows what was built, and what's behind the drywall |
| Every payment, with dates and amounts | Bank statements, cheques, e-transfer receipts | Compares what you paid against what was done |
| The contract, quotes and change orders | Email, paper copies | Sets out what was promised |
| Every message with the contractor | Texts, email, voicemail | Shows missed dates and unanswered calls |
| The permit, drawings and inspection results | Permit card on site, the town's portal | Tells the next builder where the job stands with the town |
| Receipts for materials on site | Contractor invoices, supplier receipts | Shows what you paid for and should keep |

Note: This is the list we ask for when we look at a stalled job, from a builder's point of view; a lawyer may want more.

Then write a short list of what's done and what isn't, room by room. Put it next to the payments. If you've paid for most of the job and far less of it is built, that gap is the number that matters.

## Step 3: Put it in writing

Send a written notice to the address in the contract, by email as well, and keep a copy. Say what's wrong, which part of the contract it breaks, and what you want: a date to come back and finish, or the end of the contract. Ask for the keys, any drawings, inspection reports, and materials you've paid for.

Keep it plain and factual. You may need to show it to someone later, and a calm letter reads better than an angry one.

Expect silence. The Brampton owner in the CTV W5 story said of his contractor, "He just disappeared" ([CP24, 9 Jul 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)). The written notice still matters, because it fixes the date you told them and what you asked for.

## Step 4: Call the building department about the permit

The permit is your responsibility. Ontario tells homeowners that getting building permits is on them ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)), and the permit for this job was issued for work at your address. When the contractor leaves, the open permit doesn't leave with them.

Call the building department and ask three things: which inspections have passed, whether the permit can carry on with a new contractor, and whether the drawings need to be revised. A revision has a fee. In Durham Region, Ontario, Pickering lists $180 for a revision to a house permit ([City of Pickering, 2026 fee schedule](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING)) and Clarington charges $182.03 an hour, with a one-hour minimum for a house ([Municipality of Clarington, building fee schedule](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington)).

In Whitby, call the Building Division at 905.430.4305 ([Town of Whitby, Building and renovating](https://www.whitby.ca/services-and-payments/building-and-renovating/)) or email building@whitby.ca ([Town of Whitby building permits page](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)). In Oshawa, call 905-436-3311 and ask for your building inspector by name ([City of Oshawa, Building inspections](https://www.oshawa.ca/living-here/building-and-renovating/building-inspections/)), Your inspector already knows the job, and that call often tells you more than the contractor did.

If the work started with no permit at all, the cost goes up. Oshawa adds a surcharge of 50% of the permit fee when construction has begun and no application has been received ([City of Oshawa, By-law 33-2009 as amended](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf)). Whitby charges the greater of $100 or 25% of the application fee for work started before the application ([Town of Whitby, 2026 Building Services Fees, Schedule N](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf)). Then the hidden work has to be shown to an inspector, which usually means opening it up.

## Step 5: What the next contractor needs from you

The new contractor needs to know what's there before they can price finishing it. Give them the drawings, the permit, the inspection results, your photos and the list of what was paid for. Then expect them to want to look behind the finished work.

That can mean opening walls. A builder can't put their name on wiring, framing or plumbing they can't see. If drywall went up before an inspection, or nobody can show which inspections passed, the honest answer is to cut it open and look.

Electrical is the one to check first. Only licensed electrical contractors may do electrical work in your home, and a notification has to be filed with the Electrical Safety Authority before work starts ([ESA, Finding the right contractor](https://esasafe.com/compliance/finding-the-right-contractor/)). If you can't find out who did the wiring, or whether ESA was told, the new electrician has to start by finding out.

## What does it cost to take over a half-finished job?

More than finishing a job the same firm started, almost every time, and we won't put a number on it here because it depends on what's behind the walls. The cost comes from four places: checking and opening up work that's already done, fixing what's wrong before building on it, any drawing revisions and re-inspections, and the new crew learning a house someone else framed.

What you've already lost is a separate number. A Brampton owner paid $33,000, about 90% of the contract, for a basement apartment still unfinished two and a half years later ([CP24, 9 Jul 2026](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/)). A Richmond Hill owner paid $55,000 for a six-week job that was about 80% done after six months (same story). A Mississauga family paid $85,000 for a basement apartment with a separate entrance that was never finished ([CP24, 22 May 2025](https://www.cp24.com/local/peel/2025/05/22/ontario-family-says-company-doing-their-basement-renovation-took-85000-and-never-finished-the-work/)). Closer to home, a Durham poster on RedFlagDeals described a contractor who left a basement entrance with the concrete half-poured and refused to finish ([RedFlagDeals](https://forums.redflagdeals.com/aware-bad-contractors-2285449/3/)).

Don't let the money already spent push you into hiring the cheapest person to finish. That's often how people end up doing this twice.

## Where can I complain about a contractor in Ontario?

Start with the province. Ontario's page on renovation rights links to its consumer complaint process through Consumer Protection Ontario ([Ontario, Your rights when starting home renovations or repairs](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs)). Your town's building department deals with building complaints too: Whitby's page tells people following up on a complaint to call the Building Division ([Town of Whitby, Building and renovating](https://www.whitby.ca/services-and-payments/building-and-renovating/)).

Two places that won't help with a renovation: the HCRA and Tarion. HCRA says "renovators aren't licensed or regulated like new home builders and sellers are" ([HCRA, Finding a renovator](https://www.hcraontario.ca/resources/finding-a-renovator/)), and Tarion's warranty is for new homes, excluding "alterations, deletions or additions made by the homeowner" ([Tarion, What is not covered](https://www.tarion.com/homeowners/what-is-not-covered)). To get money back, you'll need a lawyer's advice on your contract.

## How we take over a job

We'll say it plainly: taking over another firm's half-built work is a job we price carefully, and sometimes higher than you'd expect. We're putting our name on the whole thing, including work we didn't do. Until we've seen inside the walls, we don't know if the framing matches the drawings, if the wiring was done by a licensed electrician, or if the shower pan was built right. So we price the checking and the fixing separately from the finishing, and we tell you which is which.

James comes to the house first and walks it with your file: the contract, the photos, the permit and the inspection results. If the drawings need a revision, Ceara Jarvis's studio, Juliette Interiors, redraws them and we take the revision to the town. Then one crew finishes it, we book the inspections, and we walk the house with you at handover. Explore our case studies on the [projects page](https://www.jarviscontracting.ca/projects).

Before you hire anyone to finish, go through our [questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor) and the [signs of a bad contractor](https://www.jarviscontracting.ca/post/signs-of-a-bad-contractor-before-you-hire-an-ontario-homeowner-s-checklist). The second contractor deserves the same checks as the first.

## Questions

### Can I fire my contractor in the middle of a renovation in Ontario?

Whether you can end a renovation contract mid-project in Ontario depends on what the contract says and what the contractor has failed to do. Read the contract first, document the missed dates and work, send written notice, and get an Ontario lawyer's advice if a large amount of money is involved.

### What should I do if my contractor abandoned the job?

If a contractor has abandoned your renovation, stop paying, photograph the house as it stands, gather every payment record and message, and send written notice to the address in the contract. Then call your town's building department to find out which inspections passed and how the permit can carry on.

### Does a new contractor need a new building permit?

A new contractor taking over a renovation often works under the existing building permit, but the building department decides. Call them before work restarts and ask whether the permit can continue and whether the drawings need a revision, which carries its own fee, such as $180 for a house permit revision in Pickering.

### Will a new contractor charge more to finish someone else's work?

A new contractor usually charges more to finish someone else's renovation than to finish their own, because they have to check, open up and sometimes fix work they didn't do before they can stand behind it. How much more depends on what's behind the walls.

### Can I get my money back from a contractor who didn't finish?

Getting money back from a contractor who didn't finish depends on your contract, your records of payments and work done, and legal advice. If you signed at home and you're still inside Ontario's 10 calendar-day cooling-off period, you can cancel without a cancellation fee; after that, talk to a lawyer.

### Who do I complain to about a renovation contractor in Ontario?

Complaints about a renovation contractor in Ontario go through Consumer Protection Ontario, which the province links from its renovation rights page. Building problems on your house can go to your town's building department. The HCRA and Tarion don't handle renovations, because renovators aren't licensed by the HCRA and Tarion covers new homes.

If you're in Whitby or nearby with a job someone else left half-done, [send us your file](https://www.jarviscontracting.ca/contact) and we'll come and look.

# Removing a Load-Bearing Wall to Open Up Your Main Floor

By Jarvis Contracting. Published 2026-09-06, updated 2026-10-05.

Removing a load-bearing wall in Ontario takes a licensed engineer to size the beam and posts that replace it, and a building permit before the wall comes down. As of October 2026 that permit is charged at [$10.65 per m² in Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf), [$7.79 per m² in Oshawa](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) and [$7.37 per m² in Pickering](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING). Any wiring that moves has to be done by a [licensed electrical contractor](https://esasafe.com/compliance/finding-the-right-contractor/) under an ESA notification.

## Key takeaways

- Whitby charges $10.65 per m² for residential alterations, with a $305 minimum, under its [2026 building fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf).
- Oshawa's only interior alteration rate for a house is $7.79 per m² (the line reads "House, Finishing Basement"), charged on at least 50 m² with a $160 minimum, under [Building By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).
- Pickering raised its interior partitioning and finishing fee to $7.37 per m² on July 1, 2026, with a $180 minimum, in its [2026 user fees](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING).
- Toronto charges $11.53 per m² of area affected for interior alterations in 2026, per the [Toronto building permit fees](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-fees/).
- Once a house permit application is complete, Ontario's [Building Code](https://www.publications.gov.on.ca/301880) gives the building department 10 business days to issue or refuse it.
- Ontario recommends paying a renovation deposit of no more than 10%, according to its [guide to your renovation rights](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs).

## How do you tell if a wall is load-bearing?

You can make a good guess from clues, but a licensed structural engineer decides. Here is what we look at before calling one:

- **What's under it.** Go to the basement. If there's a steel or wood beam, a row of posts or a foundation wall directly below the wall, it's very likely carrying load.
- **Which way the joists run.** A wall that runs across the floor or ceiling joists, rather than alongside them, often supports them. In a lot of bungalows that's the wall between the kitchen and the living room.
- **What's above it.** A wall on the upper floor stacked over it, or roof framing landing on it, is a strong sign.
- **What the house has been through.** Past renovations move loads around. A wall that wasn't bearing when the house was built may be holding something up now.

A small inspection hole in the ceiling tells us a lot. The engineer then confirms what the wall carries, sizes the beam, and specifies the posts and footings. Nobody on our crew guesses, and you shouldn't either. Getting it wrong shows up as a sagging floor upstairs, cracked drywall and doors that stick, sometimes months later.

## What replaces a load-bearing wall?

A beam carries the load where the wall used to, and posts at each end carry it down. Those posts become point loads, and every point load needs a clear path to a footing. That's the part people forget: the work often starts in the basement, with a new pad footing under each post, before anything happens upstairs.

The two big choices are where the beam sits and what it's made of:

- **Dropped or flush.** A dropped beam hangs below the ceiling and gets boxed in with drywall or trim. It's simpler and usually cheaper. A flush beam sits up inside the ceiling, in line with the joists, so the ceiling stays flat. It means cutting and rehanging joists on hangers, and it isn't always possible if ducts or plumbing run through that space.
- **Steel or engineered wood.** Engineered wood beams (often called LVL) are lighter, go in without a crane and suit moderate spans. Steel carries more in a shallower section, which helps with a long opening or a flush beam where depth is tight. The engineer picks based on the span and the load.

While the wall comes out, we hold the house up with temporary shoring walls on both sides. After the beam is in, there's patching to do: a strip of floor where the wall stood, ceiling drywall, and sometimes flooring that doesn't match from one room to the next. Plan for that in the design, not after the wall is gone.

## What moves with the wall?

Interior walls are rarely empty. Before we open one, we check for:

- **Ductwork.** Supply and return runs to the upper floor often go up through interior walls. They get rerouted through a bulkhead, a closet or the floor system.
- **Plumbing.** A vent or drain stack from an upstairs bathroom is the most common surprise. Moving a stack is real plumbing work and can change where the bathroom above can drain.
- **Wiring.** Switches, outlets and circuits in the wall all move. In Ontario only a [licensed electrical contractor](https://esasafe.com/compliance/finding-the-right-contractor/) may do electrical work in your home, a general contractor isn't licensed for it, and a notification of work has to be filed with the Electrical Safety Authority before it starts.
- **Gas.** If the new layout moves the range or a fireplace, gas piping work needs a [TSSA certificate holder](https://www.ontario.ca/laws/regulation/010212).

## Do you need a permit to remove a wall in Durham Region?

Yes. Removing a load-bearing wall changes the structure, and Ontario's [Building Code Act](https://www.ontario.ca/laws/statute/92b23) requires a permit to construct. In Durham Region, Ontario, each town sets its own fee. Here is what the alteration permit costs in the towns we work in, as of October 2026:

| Town | Interior alteration fee | Minimum fee | 1,000 sq ft (92.9 m²) main floor |
|---|---|---|---|
| Whitby | [$10.65 per m²](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) | $305 | about $989 |
| Oshawa | [$7.79 per m²](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) | $160 | about $724 |
| Pickering | [$7.37 per m²](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING) | $180 | about $685 |
| Toronto | [$11.53 per m²](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-fees/) | $214.79 | about $1,071 |

Note: rates are each municipality's published 2026 fee for interior work; the right-hand column is our arithmetic for a whole 1,000 sq ft floor, and the building department measures the area and sets the actual fee. Plumbing fixture fees, where a town charges them, and ESA fees are separate.

The permit needs drawings showing the new opening and the engineer's beam, post and footing details. Once the application is complete, the Building Code gives the building department [10 business days](https://www.publications.gov.on.ca/301880) to decide for a house with no unit above another. Inspectors then check the framing before it's covered. In Whitby, a request in by [3 p.m. can be scheduled for the next business day](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/).

Skipping the permit costs more than the permit. Whitby adds the [greater of $100 or 25% of the application fee](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) when work starts before an application, and Oshawa adds a [50% surcharge](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) when there's no application at all. Unpermitted structural work also tends to surface when you sell.

Heritage districts rarely stop interior work. In a Heritage Conservation District, such as Werden's Plan or Brooklin in Whitby, the [Ontario Heritage Act](https://www.ontario.ca/laws/statute/90o18) requires a heritage permit to alter the property other than the interior. An individually designated house is different: if the designation lists interior features, you need the council's written consent to alter them.

### Opening up a kitchen in Pickering

Pickering moved to new fees on July 1, 2026: interior partitioning and finishing went from $6.15 to [$7.37 per m² of floor area](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING), the minimum fee is $180, and revising a house permit costs $180. That last one matters, because a wall that turns out to hide a stack can change the drawings. Applications go through the City's [online portal](https://www.pickering.ca/business-building-development/building-and-renovating/building-permits/). Whitevale is a [Heritage Conservation District](https://www.pickering.ca/business-building-development/planning-and-development/heritage-planning/), but interior work there doesn't need a district heritage permit. TRCA and CLOCA regulate additions near valleys and creeks, not walls inside the house. And if opening up the main floor is part of creating a separate unit, Pickering makes [ADU registration mandatory](https://www.pickering.ca/business-building-development/building-and-renovating/additional-dwelling-units/) under By-law 8040/23.

## Planning the kitchen once the wall is gone

Most main-floor openings are really kitchen projects. With the wall gone, the kitchen is on show from the living room, so the layout has to work from every side.

- **The island becomes the divider.** It's where people sit, where the sink or cooktop may go, and what you see from the sofa. If it carries a sink or cooktop, plumbing, venting and power have to reach it through the floor, which is easier to plan while the floor is open.
- **You lose wall cabinets.** The wall you removed may have held uppers. Make it back with a pantry wall, deep drawers and an island with storage on both sides.
- **Venting matters more.** Cooking smells and noise now reach the whole floor. A range hood ducted to the outside, sized for the cooktop, is worth planning in from the start.
- **Light and sightlines.** Opening up usually brings daylight from the back of the house to the front. Put the beam, bulkheads and pot lights on the same drawing so they line up.

For budgets, our [kitchen remodel cost post](https://www.jarviscontracting.ca/post/average-cost-of-kitchen-remodel-in-ontario-2026-budgeting-guide) has the published Ontario ranges, and our [kitchen renovations page](https://www.jarviscontracting.ca/kitchen-renovations) shows how we build them.

## Living through a main floor renovation

You can usually stay in the house, but expect weeks without a kitchen. We set up a temporary kitchen somewhere else in the house, seal the work area with dust walls and protect the floors you're keeping. The noisy, dusty days are demolition and the beam install. We'll tell you in advance when water, power or gas will be off, and for how long. If the bathroom above shares a stack with the wall coming out, plan for a stretch when that bathroom is out of service too.

## How we'd open up your main floor

James comes to the house first, goes into the basement and the attic, and tells you which walls are likely bearing and what's probably inside them. Ceara Jarvis's studio, Juliette Interiors, designs the new layout and the kitchen with us, so the beam, the island and the lighting are on one set of drawings. A licensed engineer sizes and stamps the structure. We apply for the permit, a licensed electrical contractor files the ESA notification, and one crew does the work. We book the inspections and hand the house back with the permit closed.

You can see finished work on our [projects page](https://www.jarviscontracting.ca/projects), and we're writing up more case studies now. The [Greenwood project](https://www.jarviscontracting.ca/projects/greenwood) was a ten-month renovation in Toronto that we took through permit, design and construction. If you're weighing who should do the job, our [design-build vs general contractor guide](https://www.jarviscontracting.ca/guides/design-build-vs-general-contractor) lays out the difference.

## Questions

### How do I know if a wall in my house is load-bearing?

You know a wall is load-bearing for certain only when a licensed structural engineer confirms it. Strong clues are a beam, posts or a foundation wall directly below it in the basement, joists that land on it, or a wall stacked above it. We look at those on the first visit, then the engineer decides and sizes the beam.

### Do I need a permit to remove a load-bearing wall in Ontario?

You need a building permit to remove a load-bearing wall in Ontario, because it changes the structure of the house. As of October 2026 the alteration fee is $10.65 per m² in Whitby, $7.79 per m² in Oshawa (its house interior rate, charged on at least 50 m²) and $7.37 per m² in Pickering. The application needs drawings with the engineer's beam and footing details.

### Can I have a flush beam instead of a dropped beam?

A flush beam is possible when the joists can be cut and rehung on the beam and nothing else needs that ceiling space. Ducts, plumbing or a short ceiling depth can rule it out. Steel often makes a flush beam work where engineered wood would be too deep.

### What happens to the ducts and pipes inside a wall I remove?

The ducts and pipes inside a removed wall get rerouted, usually through a bulkhead, a nearby closet or the floor system. A plumbing stack from an upstairs bathroom is the hardest to move. Any wiring in the wall is moved by a licensed electrical contractor under an ESA notification.

### Can I stay in my house while you open up the main floor?

You can usually stay in your house during a main floor opening, but you'll be without a kitchen for a stretch. We set up a temporary kitchen, seal the work area against dust and tell you ahead of time when water, power or gas will be off.

### How long does a building permit take to remove a wall?

A building permit to remove a wall in a house is due within 10 business days of a complete application under Ontario's Building Code. The clock only starts once every part of the application is in, including the engineer's drawings. Questions back from the examiner add time, so we plan for them.

# Basement Finishing Cost in the GTA: 2026 Guide

By Jarvis Contracting. Published 2026-09-04, updated 2026-10-13.

Finishing a basement in the GTA costs $55 to $90 per square foot in our 2026 range, before 13% HST. That rate is where the budget starts, not where it ends: a bathroom, a door to the outside and any foundation work are priced on top, and they're where most basement budgets grow.

This guide is about finishing a basement for your own family to use. If you want a legal second unit to rent or house a relative, the rules and the costs are different: see our guides to [what a legal basement apartment costs](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) and [what it has to meet](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario).

## Key takeaways

- Our 2026 range for finishing a basement for your own family is $55 to $90 per square foot, before 13% HST.
- A basement bathroom runs $25,000 to $50,000 in our 2026 range, and the top end is when new plumbing has to go under the slab.
- A separate side entrance runs $18,000 to $28,000, and underpinning the full perimeter $60,000 to $120,000, both our 2026 ranges before HST.
- Oshawa charges [$7.79 per square metre to finish a basement](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) as of 1 January 2026, and Whitby charges [$10.65 per square metre for alterations](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf).
- Oshawa adds a [surcharge of 25% to 50% of the permit fee](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) when basement work starts without a permit.

## What does finishing a basement cost in the GTA in 2026?

The per-square-foot rate is the floor, not the total. Here are our 2026 ranges for each piece of a basement job:

| Item | Our 2026 range |
|---|---|
| Finishing a basement for your own use | $55 to $90 per sq ft |
| Basement bathroom | $25,000 to $50,000 |
| Separate side entrance | $18,000 to $28,000 |
| Underpinning the full perimeter | $60,000 to $120,000 |

Note: these are Jarvis Contracting's own 2026 ranges, before 13% HST. They aren't a quote: James prices your basement once he has seen it, and the contract is a fixed price.

The rate per square foot covers the finish. What most families add on top is a bathroom, a bedroom with a proper window, or whatever the foundation needs before any of it goes in. Each of those is priced as its own line. The bathroom range is wide because of the plumbing: the top end is when a new drain has to go under the slab.

## What adds cost to a basement?

Water comes first. A basement that leaks will ruin a finished one, so before we frame anything we look for the signs: stains on the block, white salt on the concrete, a damp smell, a sump pit that runs often. Weeping tile that's crushed or blocked, gutters that dump next to the wall, or ground that slopes toward the house all show up as water inside. Some of that is fixed outside with grading and downspouts. Some needs the wall dug out and waterproofed, or an interior drain to a sump. It's cheaper to fix before the drywall than after.

**Ceiling height.** If the ceiling is low, the options are to live with it, lower the floor with a bench footing, or underpin. A bench footing steps a new concrete ledge inside the old footing and gives up some floor around the edge. Underpinning digs below the old footing in sections and pours new concrete under it, which keeps the full floor but costs more. For the full perimeter, our 2026 range is $60,000 to $120,000. Either way an engineer designs it and it needs a permit.

**Plumbing.** A bathroom below the main sewer line needs a pump, and a new drain usually means cutting the slab. Each fixture is also a permit line: Whitby charges [$27.80 per plumbing fixture](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) and Oshawa [$27 per fixture in a house](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).

**Ducts, beams and the furnace.** Ducts and a centre beam usually decide where the ceiling can sit. Moving ducts costs money; boxing them in costs headroom. The furnace and water heater need clear space around them, so they shape the layout.

**Electrical.** New circuits, pot lights and a bedroom smoke alarm all mean electrical work, and in Ontario that has to be done by a licensed electrical contractor who files a [notification with the Electrical Safety Authority](https://esasafe.com/compliance/finding-the-right-contractor/) before starting.

**A door to the outside.** A walkout or side entrance cuts the foundation wall, so it's structural work with its own engineering. A separate side entrance runs $18,000 to $28,000 in our 2026 range; a walkout depends on how the ground falls, so we price it after seeing the lot.

## Does a basement for your own use have to meet the second-unit rules?

No. The Ontario Building Code's [minimum ceiling height of 1.95 metres, and 1.85 metres under beams and ducts](https://www.publications.gov.on.ca/301880), is written for secondary suites, meaning a separate apartment. A basement you finish as a family room, an office or a bedroom for your own kids isn't a secondary suite. It still needs a permit for the framing, plumbing and other work, and a basement bedroom still needs a window you can get out of. The suite rules on fire separation don't apply, and the building department tells you which height rules your plans have to meet.

That changes the moment you rent it out or build a separate kitchen and entrance for someone else. If that's the plan, design for it now. See our guide to [legal basement apartment requirements](https://www.jarviscontracting.ca/guides/legal-basement-apartment-requirements-ontario).

## What do basement permits cost in Durham Region?

Each of these Durham towns charges by the square metre of finished area, at its own rate. Here are the 2026 rates, with our arithmetic for an 800 square foot (74.3 square metre) basement:

| Town | Rate | 800 sq ft basement (our arithmetic) | Minimum fee |
|---|---|---|---|
| [Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) (residential alterations) | $10.65 per m² | about $792 | $305 |
| [Oshawa](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) (finishing a basement) | $7.79 per m² | about $579 | $160 |
| [Pickering](https://corporate.pickering.ca/WebLink/DocView.aspx?id=261891&dbid=0&repo=PICKERING) (interior finishing, from 1 July 2026) | $7.37 per m² | about $548 | $180 |
| [Clarington](https://weblink.clarington.net/WebLink/ElectronicFile.aspx?docid=438584&dbid=0&repo=Clarington) (interior alterations) | $5.48 per m² | about $407 | $135.31 |

Note: these are the building permit fees only, from each town's 2026 schedule. Plumbing fixtures, underpinning and entrances can add separate lines, and none of this is the cost of the work.

A few local points that don't hold everywhere:

- **Oshawa penalises skipping the permit.** Its by-law adds [25% of the fee if you've applied, 50% if you haven't](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf), when work has started without a permit.
- **Ajax prices a below-grade entrance on its own.** The Town of Ajax lists a [$329 flat fee for a below-grade entrance](https://ajax.ca/wp-content/uploads/2026/07/Building-By-law-48-2023-Sch_A-Jan-01-2026.pdf) as of 1 January 2026.
- **Walkouts near a creek.** In Whitby and Oshawa, grading or new structures in an area regulated by the [Central Lake Ontario Conservation Authority (CLOCA)](https://www.cloca.com/inquiries-permits) can need a CLOCA permit as well as the building permit.
- **Inspections are quick to book.** Whitby schedules an inspection for the [next business day if you ask by 3 p.m.](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/)

Our guide to [basement permits in Durham Region](https://www.jarviscontracting.ca/guides/basement-permits-durham-region) covers the application itself.

## How do you pick a basement contractor?

Pay as the work gets done, not up front. Basements are where a lot of renovation horror stories happen. CP24 reported in July 2026 on a Brampton owner who [paid $33,000, about 90% of the contract](https://www.cp24.com/news/canada/2026/07/09/he-just-disappeared-this-contractor-has-a-long-list-of-angry-clients/), for a basement apartment still unfinished two and a half years later. Ontario recommends a [deposit of no more than 10%](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) and a written contract.

Ask who pulls the permit, who designs any underpinning, and who books the inspections. Our list of [questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor) goes further.

## How we'd finish your basement

James starts at the house. He checks the walls and floor for water, measures the ceiling to the beam and the ducts, and looks at where the drains and the panel are. That visit tells us if you're looking at a finish job, or foundation work first.

Then Ceara Jarvis and her studio, Juliette Interiors, lay out the rooms, the bathroom and the lighting with you, and we draw it for the permit. If the floor has to come down or a door has to go through the wall, a licensed engineer designs that part. One crew builds it, we book each inspection as the work closes in, and we hand it over when the town has signed it off.

You can see our [projects](https://www.jarviscontracting.ca/projects); the case studies include photographs and project details. Our [pricing page](https://www.jarviscontracting.ca/pricing) explains how we price.

## Questions

### How much does it cost to finish a basement per square foot in the GTA in 2026?

Finishing a basement in the GTA costs $55 to $90 per square foot in our 2026 range, before 13% HST. Bathrooms, entrances and moisture work are priced on top, so the rate per square foot is where a basement budget starts.

### Do I need a permit to finish my basement in Ontario?

Finishing a basement in Ontario needs a building permit when you're framing walls, adding plumbing or changing structure, which covers almost every real basement finish. Durham Region towns publish a rate for it: Oshawa charges [$7.79 per square metre](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) as of 1 January 2026. Electrical work also needs an [ESA notification](https://esasafe.com/compliance/finding-the-right-contractor/).

### What is the difference between a finished basement and a legal basement apartment?

A finished basement is living space for your own household; a legal basement apartment is a second dwelling unit with its own entrance, kitchen and bathroom, built to the secondary-suite rules for fire separation and ceiling height. The legal unit costs more and has more rules: a full legal basement apartment runs $80,000 to $180,000 in our 2026 range. Our guide to [legal basement apartment costs](https://www.jarviscontracting.ca/guides/legal-basement-apartment-cost-ontario) covers it.

### Can I finish my basement if the ceiling is low?

A basement with a low ceiling can often still be finished, by working around the beam and ducts, by lowering the floor with a bench footing, or by underpinning. Underpinning the full perimeter runs $60,000 to $120,000 in our 2026 range, and an engineer designs it.

### What are the hidden costs in a basement renovation?

The hidden costs in a basement renovation are mostly under or behind it: water problems at the foundation, crushed weeping tile, a bathroom that needs a pump, ducts that have to move, and a panel with no room for new circuits. A visit before the price catches most of them.

### Is a walkout worth adding when you finish a basement?

A walkout adds light, a second way out and a door to the yard. Whether it's worth it depends on the grade outside: a lot that falls away at the back makes it far easier, so we price a walkout after seeing the lot. A separate side entrance, for comparison, runs $18,000 to $28,000 in our 2026 range.

# Kitchen Design Ideas from Real Jarvis Homes

By Jarvis Contracting. Published 2026-08-31, updated 2026-10-09.

The most useful kitchen inspiration shows how a room works as well as how it looks. These ideas come from photographs of Jarvis homes: a place for coffee, a defined cooking wall, storage that follows the architecture and surfaces that connect the kitchen to the rest of the house.

## Give one daily ritual its own place

At [Bellamy](https://www.jarviscontracting.ca/projects/bellamy), an oak-lined coffee niche includes an espresso machine, a shelf and a brass rail. At [French Contemporary](https://www.jarviscontracting.ca/projects/french-contemporary), a charcoal cupboard and walnut shelves set the coffee counter apart from the white kitchen.

Both examples give a frequently used activity a clear home. When planning your version, list the appliances, cup storage, power needs and space required to refill or clean them. A photograph provides an idea; the working dimensions come from your equipment.

## Let the cooking wall have a shape

[Coventry Residence](https://www.jarviscontracting.ca/projects/coventry-residence) uses a plaster range alcove with built-in shelves. [Orchard Residence](https://www.jarviscontracting.ca/projects/orchard-residence) has a panelled hood and a broad veined backsplash. These are different ways to organise the cooking wall within the room.

Choose the range and ventilation requirements before fixing decorative dimensions. Ask how the hood can be accessed for cleaning and servicing, and which parts of the surrounding cabinetry are practical storage.

## Treat storage as part of the elevation

A tall pantry is visible from the living room as well as the kitchen. Compare the pantry, appliance fronts and open shelving as one composition. The [Aurelia gallery](https://www.jarviscontracting.ca/projects/aurelia) includes reeded-glass cabinet doors, stone surfaces and a dining area that can be studied together.

The goal is not to hide everything. Decide which objects you want within reach and which should disappear when the room is in use.

## Price the choices separately

Separate layout changes from finish choices. Keeping plumbing in place while changing cabinet fronts is a different project from moving walls, drains and appliances. Our [kitchen budget guide](https://www.jarviscontracting.ca/post/average-cost-of-kitchen-remodel-in-ontario-2026-budgeting-guide) explains why published price labels vary.

For your brief, choose three photographs and write one sentence about what you like in each. 'The coffee area is separate' is more useful than 'I want this exact kitchen.' Bring that brief to the [first conversation](https://www.jarviscontracting.ca/contact) so design can start with how you live.

## Questions

### Should I choose finishes or the layout first?

Settle the major layout, equipment and storage needs first. Finishes can then be compared within a room that works, rather than driving cabinet or service changes late in the process.

# Whole-Home Renovation in Toronto: Planning and Phasing

By Jarvis Contracting. Published 2026-08-25, updated 2026-10-13.

A whole-home renovation in Toronto runs in a fixed order: approvals, then structure and the outside shell, then the plumbing, heating and electrical rough-ins and their inspections, then insulation, drywall and finishes. The approvals are the part people underestimate. A minor variance at Toronto's Committee of Adjustment costs [$2,228.98 for additions and alterations to a house](https://www.toronto.ca/city-government/planning-development/committee-of-adjustment/forms-submission-guidelines-fees/) as of 2026, and once your application is complete, the City's House Stream reviews the building permit [within 10 business days](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-review-streams/). Most families move out for the heavy middle of the job, and doing it all at once is usually faster and cheaper than phasing.

## Key takeaways

- The City of Toronto reviews complete permit applications for houses of up to two units [within 10 business days](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-review-streams/) through its House Stream, as of October 2026.
- Toronto's 2026 permit fee is [$11.53 per square metre for interior alterations](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-fees/) and [$18.56 per square metre of new floor area](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-application-guides/renovation-and-new-house-guides/small-residential-additions/) for an addition.
- Toronto's Committee of Adjustment saw [2,240 minor variance applications in 2025](https://open.toronto.ca/dataset/committee-of-adjustment-applications/), 962 of them for additions and alterations to houses of three units or fewer.
- Toronto has created [27 heritage conservation districts since 1985](https://www.toronto.ca/city-government/planning-development/heritage-preservation/heritage-conservation-districts-planning-studies/), and work in one is reviewed by Heritage Planning as part of the building permit.
- If your lot sits in a regulated ravine or valley, a [TRCA permit comes before the City's building permit](https://trca.ca/planning-permits/apply-for-a-permit/), and TRCA's minor permit for private residential work is [$560](https://trcaca.s3.ca-central-1.amazonaws.com/app/uploads/2026/02/25090657/Development-Permitting-Fee-Schedule-February-1-20260225.pdf).
- Moving has its own bill: Ontario's land transfer tax alone on a $1.2 million house is about $20,475 at the [province's 2026 rates](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax), before Toronto's own land transfer tax, commission and legal fees.

## What order does a whole-home renovation happen in?

The rule is simple: nothing gets covered until it has been inspected, and nothing gets finished until the house is closed to the weather. Here is the order we follow:

1. **Price, measure and design.** James prices the whole job and you sign the contract, then we measure the house as it is and design the house you want.
2. **Approvals.** Zoning review, a Committee of Adjustment hearing if a variance is needed, heritage review if you're in a district, a TRCA permit if you're in a regulated area, then the building permit.
3. **Demolition.** Strip out what's coming out. In an older Toronto house this is when we test plaster and insulation for hazardous materials and find out what the walls are hiding.
4. **Structure.** New footings, underpinning, beams and posts, new framing. A licensed engineer designs and stamps anything structural.
5. **The shell.** Roof, windows, exterior doors and any new exterior walls, so the house is dry before anything inside goes in.
6. **Rough-ins.** Heating ducts first because they're the biggest and least flexible, then drains and water lines because drains need slope, then wiring, which bends around everything else.
7. **Inspections.** Framing, plumbing, heating and electrical rough-ins are inspected while the walls are open. Electrical goes through the [Electrical Safety Authority](https://esasafe.com/compliance/finding-the-right-contractor/), the rest through Toronto Building.
8. **Insulation and drywall.** Insulation is inspected before the drywall covers it.
9. **Finishes.** Flooring, the kitchen, the bathrooms, tile, trim, paint and fixtures go in last, once the dust from the rough work is gone.
10. **Final inspection and handover.**

Doing these out of order is how budgets break. Finish a bathroom before the beam above it goes in, and you'll be fixing cracked tile later.

## Should you renovate all at once or in phases?

All at once is faster, cleaner and cheaper, if you can manage it. Every phase reopens the site. The house has to be protected again, dust walls go back up, and trades come back for small pieces of work that cost more per hour than a full day. Each phase may need its own permit or a revision to the first one, and its own round of inspections. The seams between phases are where work gets done twice: a wall finished in phase one gets opened in phase two to run a pipe.

We can't put a number on what phasing adds, because it depends on how many phases, how far apart, and what's at the seams. But it is never free.

Phasing does make sense when the budget has to be spread over years, or when you can't move out and need part of the house working. If you phase, plan the whole house first:

- Draw the finished house before building any of it, so phase one doesn't block phase two.
- Size the electrical panel, the furnace and the water lines for the finished house, not the first phase.
- Put the structural work and the roof in the first phase if you can. They're the most disruptive and they protect everything after.
- Phase by floor, not by room, so each phase can be closed off from the part you're living in.

## Can we live in the house during a whole-home renovation?

Usually not for the heavy middle. During demolition, structure and rough-ins, the water, power and heat go off for stretches, the floors are open, and the dust gets everywhere. A reply on a Houzz thread about staying home through a second-floor addition put it bluntly: ["your whole house will be a mess"](https://www.houzz.com/discussions/6116203/staying-during-a-second-floor-addition). Houzz is mostly American posters, but the dust is the same here.

Most families rent nearby or stay with family for the structural and rough-in stages, and some move back in for the finishes if one floor is done and closed off. If you can't move out at all, the job has to be phased, and it will take longer and cost more.

Plan the rent into the budget from the start. It's the cost people leave out.

## Is it cheaper to move than to renovate the whole house?

Moving in Toronto costs money before you've changed anything. You'd pay Ontario's land transfer tax on the purchase, at rates that rise from [0.5% on the first $55,000 to 2.5% above $2 million](https://www.ontario.ca/document/land-transfer-tax/calculating-land-transfer-tax), and Toronto charges a second, municipal land transfer tax on top. On a $1.2 million house the provincial tax alone is about $20,475 (our arithmetic). Add commission, legal fees and the move itself, and the bill is large before any difference in house price.

A full gut of the house may also qualify for HST relief. The CRA treats a [substantial renovation, where at least 90% of the interior is removed or replaced](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html), much like a new home for its rebates, and Ontario's enhanced rebate covers owner-built and substantially renovated homes where [construction begins between 1 April 2026 and 31 March 2027](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html). Check it with your accountant. Our guide to [HST relief on a substantial renovation](https://www.jarviscontracting.ca/guides/ontario-hst-relief-substantial-renovation) explains the rules, and [renovate or move](https://www.jarviscontracting.ca/guides/renovate-or-move) walks through the trade-off.

## What's different about renovating a house in Toronto?

Toronto layers more approvals onto a whole-home job than the towns around it. Here's what applies as of October 2026:

**Zoning.** Most of the city is under [Zoning By-law 569-2013](https://www.toronto.ca/city-government/planning-development/zoning-by-law-preliminary-zoning-reviews/zoning-bylaws/), with some lots still under the former municipal by-laws. If the work adds floor area or height beyond what zoning allows, you need a minor variance from the [Committee of Adjustment](https://www.toronto.ca/city-government/planning-development/committee-of-adjustment/) before the permit can issue.

**Permit fees.** Toronto charges by area: $11.53 per square metre for interior alterations and $18.56 for new floor area, with a [$214.79 minimum](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-fees/), all 2026 rates.

**Heritage.** Inside a [heritage conservation district](https://www.toronto.ca/city-government/planning-development/heritage-preservation/heritage-permit-guide/), your drawings go through Toronto Building with the permit and Heritage Planning reviews them. An individually designated property needs a heritage permit before any work starts.

**Ravines and the TRCA.** In a [Toronto and Region Conservation Authority regulated area](https://trca.ca/planning-permits/apply-for-a-permit/), meaning valleys, wetlands, hazard lands or the lake shore, the TRCA permit comes first.

**Trees.** You need a permit to injure or remove a private tree [30 cm or more across at 1.4 metres](https://www.toronto.ca/legdocs/municode/1184_813.pdf) above the ground, and a Tree Declaration Form goes in with every building permit and Committee of Adjustment application.

**Neighbours.** An addition over [100 square metres needs a Residential Infill Construction Public Notice](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-application-guides/renovation-and-new-house-guides/small-residential-additions/) posted on site.

If your house is in Durham Region, Ontario instead, the order of work is the same, and Whitby and Oshawa deal with the [Central Lake Ontario Conservation Authority](https://www.cloca.com/inquiries-permits) rather than the TRCA.

## What does a whole-home renovation cost in Toronto?

We won't give you a whole-home number without seeing the house, and you should be wary of anyone who does. We haven't found a published whole-home range we'd trust. The reason is that "whole-home" covers everything from new floors and paint throughout to a full gut with new structure, wiring and plumbing, and the biggest costs hide behind walls nobody has opened yet. Older Toronto houses turn up old wiring, sagging joists, a foundation that needs work. Approvals add their own time and fees.

What we can do is walk the house, look at what's there, and price the whole job in a detailed proposal before design starts. Our [pricing page](https://www.jarviscontracting.ca/pricing) explains how. Once you have a written estimate, Ontario law caps the final price at [no more than 10% over it](https://www.ontario.ca/page/your-rights-when-starting-home-renovations-or-repairs) unless you agree to changes.

## How we'd run your renovation

James starts at the house. He walks every floor, looks at the basement, the panel, the roof and the structure, and tells you what he'd worry about. Then Ceara Jarvis and her studio, Juliette Interiors, design the house with you, and we draw it. A licensed engineer designs and stamps the structure. We take it through the approvals and the permit, one crew builds it in order, we book every inspection as each stage closes up, and we hand the house back when the City has signed it off.

Our [Greenwood project](https://www.jarviscontracting.ca/projects/greenwood) is a ten-month renovation in Toronto that we took through permit, interior design and construction. Read the full case study and compare it with our other [projects](https://www.jarviscontracting.ca/projects).

## Questions

### How long does a whole-home renovation take in Toronto?

A whole-home renovation in Toronto takes as long as its approvals plus its build, and both depend on the house. Our Greenwood renovation in Toronto took ten months. A Committee of Adjustment variance, a heritage review or a TRCA permit each add time before construction can start.

### Do I need a permit for an interior-only whole-home renovation in Toronto?

An interior-only whole-home renovation in Toronto needs a building permit for anything structural, new plumbing or changes to walls, because the City says a permit is required for [most construction, demolition, additions or major renovations](https://www.toronto.ca/services-payments/building-construction/building-permit/). Toronto charges $11.53 per square metre for interior alterations in 2026.

### How does the Committee of Adjustment affect a renovation timeline?

The Committee of Adjustment affects a Toronto renovation timeline because no building permit issues while a needed variance is pending. The 2026 fee for a house is $2,228.98. We check the zoning before we draw, so you know early whether a variance is needed.

### Can I renovate my house in phases to save money?

Renovating a house in phases spreads the cost over time, but it rarely lowers the total. Each phase brings back site protection, trades, permits and inspections, and the seams between phases get worked twice. Phase only if the budget or living arrangements require it, and design the whole house before phase one starts.

### Is renovating a house in a Toronto heritage district harder?

Renovating in a Toronto heritage conservation district adds a review: Heritage Planning looks at your drawings as part of the building permit, mostly for changes to the outside. An individually designated house needs a separate heritage permit before work starts. Plan the exterior around the district's rules from the first drawing.

### Who designs a whole-home renovation with a design-build firm?

With a design-build firm like ours, the design and the permit drawings come from the same team that builds the house, and a licensed engineer designs and stamps the structure. You don't hire a separate designer and then a builder, so the whole-home design is drawn by the people who price and build it.

# Planning a Second Storey Addition in Durham Region

By Jarvis Contracting. Published 2026-08-16, updated 2026-10-13.

A second storey in Durham Region, Ontario starts with an engineer confirming your footings, foundation and main-floor walls can carry a new floor, then a building permit charged at [$22.37 per m² in Whitby](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) or [$15.56 per m² in Oshawa](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf), as of October 2026. If the new roof goes over the zoning height, a minor variance from the Committee of Adjustment comes first. Plan the structure and the zoning before anyone draws a bedroom.

## Key takeaways

- A 1,000 sq ft second storey works out to a permit fee of about $2,078 in Whitby and about $1,446 in Oshawa, calculated from the [Town of Whitby 2026 fee schedule](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) and [Oshawa By-law 33-2009](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf).
- Height limits are 8.5 m in the R1 to R3 zones of [Whitby By-law 1784](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) and 9.0 m in the R1-A to R1-E zones of [Oshawa By-law 60-94](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf), so check yours before design starts.
- A minor variance costs $1,526 in Whitby ([Town of Whitby application form](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf)) and $856 in Oshawa ([City of Oshawa Committee of Adjustment](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/)) for a residential lot.
- Ontario gives the building department 10 business days to decide a complete permit application for a house with no unit above another, under the [Building Code](https://www.publications.gov.on.ca/301880).
- Enlarging your own home doesn't trigger development charges under the [Development Charges Act](https://www.ontario.ca/laws/statute/97d27), and the [Canada Revenue Agency](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html) treats an addition that at least doubles your living space as owner-built for HST rebate purposes.

## Can my house carry a second storey?

Most bungalows can take a second floor, but you only know once a licensed structural engineer has looked at what's under it. The original house was framed and footed for one floor and a roof. A new storey adds a floor, walls, a roof and everything you put in them, and all of it needs a clear path down to the ground.

Here is what gets checked, top to bottom:

- **The main-floor walls.** Exterior walls and any interior bearing wall will carry the new floor. Some get new studs or headers. Where you want a wider opening below, a steel beam or engineered wood beam takes the load, and the posts at each end become point loads.
- **The floor framing.** The old ceiling joists were sized to hold up drywall and insulation, not a bedroom. They're usually replaced or sistered, or a new floor system is built over them.
- **The foundation and footings.** Every point load has to land on something that can take it. Sometimes that's the existing footing. Sometimes it's a new pad footing in the basement. Sometimes the engineer calls for underpinning or for strengthening a wall.
- **The soil and the walls you can't see.** Cracks, bowing block, water staining and old repairs all tell a story. We look for them on the first visit so they don't show up as a surprise the week the roof comes off.

The engineer's report decides this, not us and not you. We frame to the stamped drawings. If underpinning is part of the job in Whitby, the town lists it as a separate [$305 flat permit item](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf). Budget for the engineering visit before you pay for full drawings: it's the cheapest way to learn whether building up makes sense at all. If the answer is no, our [build up or out guide](https://www.jarviscontracting.ca/guides/build-up-or-out) covers the rear addition alternative.

## Permits and zoning for a second storey in Whitby and Oshawa

A second storey needs a building permit. The [Building Code Act](https://www.ontario.ca/laws/statute/92b23) doesn't let anyone construct a building without one, and an addition counts. Before the permit, though, the design has to fit the zoning by-law for your lot: height, lot coverage and setbacks. If it doesn't, you apply to the Committee of Adjustment for a minor variance, and the permit waits for that decision.

Here is how the two towns we work in most compare, as of October 2026:

| | Town of Whitby | City of Oshawa |
|---|---|---|
| Permit fee, new floor area | [$22.37 per m²](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) | [$15.56 per m²](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) |
| 1,000 sq ft (92.9 m²) addition | about $2,078 | about $1,446 |
| Maximum height | [8.5 m (R1 to R3, By-law 1784)](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) | [9.0 m (R1-A to R1-E, By-law 60-94)](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf) |
| Maximum lot coverage | [20% (R1 to R3, By-law 1784)](https://media-003-ca.cdn.govstack.com/whitby-ca/media/orfb0rfx/1784_zoning-by-law_2025_consolidation-accessible.pdf) | [40% (R1-A to R1-E)](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/xrthfhqx/zoning-by-law-60-94.pdf) |
| Minor variance fee (residential) | [$1,526](https://media-003-ca.cdn.govstack.com/whitby-ca/media/txxlnw3w/pl-application_minorvariance.pdf) | [$856 per lot](https://www.oshawa.ca/business-development/planning-and-development/development-applications/committee-of-adjustment/) |
| Building without a permit | [greater of $100 or 25% of the application fee](https://media-003-ca.cdn.govstack.com/whitby-ca/media/5aqjt5ww/2026-building-permit-fees-schedule-n.pdf) | [25% surcharge, or 50% with no application](https://media-002-ca.cdn.govstack.com/oshawa-016-ca/media/em3h4lr3/bylaw-33-2009-as-amended-by-by-law-118-2025.pdf) |

Note: fees are from each town's 2026 schedule; the 1,000 sq ft figures are our arithmetic, and the town measures the floor area and sets the final fee. Zoning limits vary by zone, so your lot's zone decides which numbers apply.

A second storey on a bungalow rarely changes lot coverage, because you're building on the footprint you already have. Height is where most second storeys get caught, especially with a steep roof. Setbacks matter if you add a bump-out at the same time. On most urban residential lots, Ontario now treats zoning setbacks as [90% of the by-law figure](https://www.ontario.ca/laws/regulation/060545), outside the Greenbelt and some areas near shorelines, wetlands, valleys and railways.

Once the application is complete, the clock is short on paper. The Building Code gives the building department [10 business days](https://www.publications.gov.on.ca/301880) to issue or refuse a permit for a house where no dwelling unit sits above another, and Saturdays and holidays don't count. "Complete" carries the weight: the provincial form, every schedule filled in, fees paid and the drawings attached. Oshawa says plainly on its permit page that with record application volumes it [cannot guarantee review timeframes](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/), so we plan for questions back from the examiner and a resubmission.

### What's different about building up in Durham Region

These are the local layers we check on every second storey east of Toronto:

- **Which zoning by-law you're under.** Whitby has [three](https://www.whitby.ca/business-and-economy/planning-and-development/zoning/): 2585 for downtown Whitby, 1784 for the former township including Brooklin, and 5581-05 for the Oak Ridges Moraine. Oshawa uses [By-law 60-94](https://www.oshawa.ca/business-development/planning-and-development/development-applications/zoning/).
- **CLOCA.** Near a creek, wetland, valley or the lakeshore, the Central Lake Ontario Conservation Authority regulates [new or enlarged structures](https://www.cloca.com/inquiries-permits). Its 2026 schedule lists a [Minor Permit B at $535](https://www.cloca.com/_files/ugd/6cdd05_ca1ea5bbdaa34f3ca770f69ab8f830e4.pdf) for minor additions and a Standard Permit C from $1,990. CLOCA issued [229 permits in 2025](https://www.cloca.com/_files/ugd/b3995f_39e00c93c1474cd4b56145440a573905.pdf) with an average review of 6.1 days.
- **Heritage districts.** Whitby has [two Heritage Conservation Districts](https://www.whitby.ca/explore-and-enjoy/heritage/), Werden's Plan downtown and Brooklin. In a district, changing the outside of a house needs a [heritage permit](https://www.ontario.ca/laws/statute/90o18), and a second storey changes the outside more than anything. Whitby charges [no fee to apply](https://www.whitby.ca/services-and-payments/building-and-renovating/heritage-permits/), but it adds a review.
- **The airport.** Near the Oshawa Executive Airport, you need [airport clearance](https://www.oshawa.ca/living-here/building-and-renovating/building-permits/) before Oshawa issues the permit.

## Do you pay development charges or HST relief on a second storey?

You don't pay development charges to enlarge the house you live in. The [Development Charges Act](https://www.ontario.ca/laws/statute/97d27) excludes an action whose only effect is enlarging an existing residential unit. Add a separate unit upstairs and that's a different question.

HST is where a full second storey can be worth a call to your accountant. The CRA lists "an addition that at least doubles the living space of your house" as a case where [owner-built rebates can apply](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html), and it names a full second storey on a bungalow as the example. The [Ontario new housing rebate](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/gst-hst-rebates/new-housing-rebate.html) goes up to $24,000. Ontario's [enhanced rebate](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/notice346/ontario-enhanced-new-housing-rebate.html) for owner-built homes generally applies where construction begins between April 1, 2026 and March 31, 2027, so the start date can matter. A sunroom or one bedroom over the garage won't qualify. Our [HST relief guide](https://www.jarviscontracting.ca/guides/ontario-hst-relief-substantial-renovation) goes through the rules.

## Can you live in the house while the roof is off?

Sometimes, but plan as if you can't. The roof comes off, the new floor goes on and the walls go up, and for that stretch the house is open to the weather under tarps. One Houzz reply to an owner hoping to stay put was blunt: ["your whole house will be a mess"](https://www.houzz.com/discussions/6116203/staying-during-a-second-floor-addition). Another builder on the same forum told an owner to [plan on nine months or more out of the house](https://www.houzz.com/discussions/6519411/putting-a-second-story-on-a-one-story-house-what-to-watch-for). Most posters there are American; the mess is the same here.

What we do about it:

- We plan the roof-off weeks around the forecast and get the house closed in as fast as the framing allows.
- We protect the main floor, but dust and some damage under tarps happen. We'd rather tell you now.
- The new stair takes a bite out of the main floor, and the furnace, ductwork and electrical service often need to change for the extra floor. Decide early if the main floor gets redone at the same time. A quote that leaves out the main floor is where second-storey budgets break.
- If you're staying, we agree in writing which rooms stay usable, which bathroom works, and when water and power go off.

## What does a second storey cost in Ontario?

Our 2026 range for a 600 to 1,200 sq ft second storey is $300,000 to $800,000, before 13% HST, and work on the floor below, like a new kitchen or bathrooms, adds to it. Our permit drawings for an addition run $6,000 to $12,000, and that price leaves out permit fees, HVAC engineering, truss design, committee of adjustment applications and anything unforeseen. What moves the number is the structure under the new floor, whether the main floor is part of the job, and HST. Our [second storey cost guide](https://www.jarviscontracting.ca/guides/second-storey-addition-cost-ontario) breaks it down.

## How we'd plan your second storey

James comes to the house first. He goes into the basement, looks at the foundation and the bearing walls, and asks what you need the space for. If building up looks sensible, we bring in a licensed structural engineer to confirm it.

Design and drawings come from Ceara Jarvis's studio, Juliette Interiors, working with us, so the floor plan, the stair and the new roofline are drawn by people who know what they cost to build. We check the zoning, handle the minor variance if one is needed, and file the permit with the engineer's stamped structure. One crew builds it, framing through finishes. We book the inspections as we go; in Whitby, a request in by [3 p.m. can be scheduled for the next business day](https://www.whitby.ca/services-and-payments/building-and-renovating/building-permits/). At handover you get the house back with the permit closed.

You can see our work on the [projects page](https://www.jarviscontracting.ca/projects). We're writing up more case studies now; the [Greenwood project](https://www.jarviscontracting.ca/projects/greenwood) was a ten-month renovation in Toronto that we took through permit, design and construction. Our [second storey additions page](https://www.jarviscontracting.ca/second-storey-additions) covers the service itself.

## Questions

### Do I need a minor variance for a second storey addition?

You need a minor variance for a second storey only if the design breaks the zoning by-law, most often the height limit. In Whitby's R1 to R3 zones under By-law 1784 the limit is 8.5 m, and in Oshawa's R1-A to R1-E zones it's 9.0 m. The Committee of Adjustment decides, and the fee is $1,526 in Whitby and $856 in Oshawa.

### How long does the building permit take for a second storey in Ontario?

For a house with no unit above another, Ontario's Building Code gives the building department 10 business days to decide a complete permit application for a second storey. The clock only starts when the application is complete, and examiners often send questions back. Oshawa says it can't guarantee review times because of record application volumes.

### Does a second storey addition need underpinning?

A second storey needs underpinning only when the engineer finds the existing footings or foundation walls can't carry the new load. Many bungalows need new footings under point loads instead, or nothing at all. In Whitby, underpinning is a separate $305 flat permit item.

### Do I pay development charges on a second storey in Durham Region?

No development charges apply to a second storey that only makes your existing home bigger. Ontario's Development Charges Act excludes the enlargement of an existing residential unit. A new separate unit is treated differently.

### Does CLOCA need to approve my second storey?

CLOCA needs to approve a second storey only if your lot is in an area it regulates, such as near a creek, wetland, valley or the Lake Ontario shoreline. Its 2026 Minor Permit B for minor additions is $535.

### Can I get an HST rebate on a second storey addition?

An HST rebate can apply to a second storey if it at least doubles the living space of your house, because the CRA treats that addition as owner-built. The Ontario new housing rebate goes up to $24,000, and an enhanced Ontario rebate covers owner-built homes where construction begins between April 1, 2026 and March 31, 2027. Confirm with your accountant before you count on it.

# Planning a Muskoka Retreat: Site, Design and Builder Questions

By Jarvis Contracting. Published 2026-08-12, updated 2026-10-09.

A lakeside retreat starts with the property and how you intend to use it. Decide whether the project is an existing-home renovation, an addition or a new building before choosing a style or comparing builders. Those choices affect the information and expertise you need.

## Let the site shape the brief

Collect the survey, available drawings and the property's servicing information. Discuss the route for deliveries, where materials can be stored, the slope of the site and the relationship between the house and the water. A photograph taken in summer does not describe access or use through every season.

Identify the responsible municipality before assuming that a rule quoted for another Muskoka property applies. The [District of Muskoka](https://www.muskoka.on.ca/) provides a starting point for local information; the project team should identify the applicable local approval authorities for the actual address. This article does not prescribe a shoreline setback or claim approval for a particular building envelope.

## Translate a style into specific decisions

'Farmhouse' can describe many different choices. Break the reference images into roof form, window proportions, cladding, timber details, interior materials and the relationship to outdoor space. Then ask what each choice means for maintenance, weather exposure and construction.

A large deck and broad glazing can change the experience of a room, but they also need to be considered with orientation, privacy and seasonal use. Write down which views and daily routines matter most before selecting finishes.

## Explore a lakeside photographic reference

The [Halliburton Haven portfolio](https://www.jarviscontracting.ca/projects/halliburton-haven) shows a navy-sided home, timber entry, long deck, vaulted great room and stone fireplace. Its gallery is useful for comparing the relationship between the exterior and interior spaces.

The portfolio name is not a verified municipal location, and the photographs do not establish whether the original work was a renovation or new construction. It is presented as a photographic reference, not as proof of a completed Jarvis build in Muskoka.

## Ask the builder to define its role

Request relevant completed work, the scope performed by the proposed team, client references and a written explanation of who handles design, approvals and construction. Check the credentials for the type of project you are commissioning. For a new home, use the [HCRA licensing guidance](https://www.hcraontario.ca/do-i-need-a-licence/) and [Ontario Builder Directory](https://obd.hcraontario.ca/).

Jarvis does not currently offer new custom homes or a Muskoka cottage-building service on this website. Our current [services](https://www.jarviscontracting.ca/services) and [coverage directory](https://www.jarviscontracting.ca/areas) describe the work offered. Keeping that distinction clear is more useful than treating every portfolio photograph as a promise about a service area.

## Questions

### Can a design from another lakeside property be reused as-is?

It is a reference, not a site-specific design. Your property, servicing, access, intended use and approval requirements need to be considered before selecting a layout.

# Choosing a Custom-Home Builder in Durham Region

By Jarvis Contracting. Published 2026-08-08, updated 2026-10-09.

When comparing custom-home builders in Durham Region, start with the builder's legal identity, current licence and the exact home they are proposing to build. Then compare scope, evidence and the contract. A polished portfolio alone cannot answer those questions.

## Check the company behind the proposal

Use the [Ontario Builder Directory](https://obd.hcraontario.ca/) to look up the company named on the proposed contract. Match the legal name and licence information, rather than relying only on a trading name on a website.

The [HCRA's licensing guidance](https://www.hcraontario.ca/do-i-need-a-licence/) explains the requirements for new-home builders and sellers, including custom homes on a client's land. Follow its advice about checking licensing and Tarion approval before signing. Our [licensing and warranty explainer](https://www.jarviscontracting.ca/guides/hcra-and-tarion-explained) distinguishes a new-home warranty from a renovator's own written warranty.

## Ask for evidence that matches your project

Look for completed work comparable in scope and complexity, not simply photographs with the style you prefer. Ask what the builder actually delivered, who designed it and whether you can speak with the homeowner.

A kitchen renovation, a second-storey addition and a new house are different scopes. A contractor should describe its role accurately in each example. Ask about work completed by the proposed team, rather than assuming that every historical photograph represents the current company and crew.

## Compare complete proposals

Use the same brief for each proposal. Clarify design, engineering, approvals, site preparation, servicing, construction, finishes and exclusions. Ask which amounts are allowances and how changes will be priced.

Discuss the decision process alongside the price: who coordinates the designers, who provides site updates and who can approve a change? Our [questions to ask a contractor](https://www.jarviscontracting.ca/guides/questions-to-ask-a-contractor) can help structure an interview, while the contract needs advice appropriate to your own circumstances.

## Where Jarvis fits today

Jarvis Contracting currently offers home additions, second-storey additions, renovations and design through this website. New custom-home construction is not currently offered here while builder licensing is pending. This article is a homeowner's selection guide, not a claim that Jarvis is a licensed new-home builder.

If your real choice is between changing your present home and starting again, explore our [renovation and addition services](https://www.jarviscontracting.ca/services) and [renovate-or-move guide](https://www.jarviscontracting.ca/guides/renovate-or-move). They help separate the two decisions without treating one service as a substitute for the other.

## Questions

### Is an addition the same service as a new custom home?

No. They involve different scopes and can have different licensing and warranty requirements. Ask each business which service it currently provides and verify the credentials relevant to that work.

Video file: https://www.jarviscontracting.ca/media/video/stone-ridge-tour.mp4 (56 seconds)

## Transcript

Welcome to Project Stone Ridge, where we completely transformed this entire basement from closed-off spaces to a full open concept. This project was really meant to feel welcoming, warm and functional for everyday life.

Behind me we have a beautiful kitchenette with custom curves that's very convenient for the homeowner. And look at this beautiful walk-through closet with these pocket doors.

As you walk through the closet into the bedroom, you are greeted with this amazing ensuite. Off the bedroom is this amazing ensuite with a curbless shower, nice custom glass and an amazing vanity.

This project truly came together as a collaboration between thoughtful design and craftsmanship. We're a family-run company and we love building things like this for other families. If you're interested in something like this, give us a call.

# Greenwood homeowner: why she'd recommend Jarvis Contracting

A Greenwood homeowner in Toronto on hiring Jarvis Contracting: one meeting, a WhatsApp group for questions, surprises explained, and the job done as promised.

Video file: https://www.jarviscontracting.ca/media/video/greenwood-homeowner-testimonial.mp4 (127 seconds)

## Transcript

So we had heard about James Jarvis and Jarvis Contracting through a friend who had used him for a renovation. So we met with him, we went over what our vision was and we talked through things, and we actually didn't talk to any other contractors. Based on that initial meeting, and all of the reviews we had had from our friend and his relatives, we felt really good about moving ahead and using Jarvis Contracting.

The most important piece was that I could rely on someone to keep the project on track and reasonably within budget. I don't have a lot of time to be managing that, and I felt from the beginning that the communication was really on point. The managing of my expectations, responding to concerns, to questions, along with obviously the reviews that we had had, made me feel really confident moving forward.

So right from the beginning we were put into a WhatsApp group, and at the time I probably didn't realize how helpful that was. Anytime I needed a question... I would try to save them until the morning, but if I had one late at night I would put one in, and it was always answered. And I felt like I was given those different options. My pricing concerns were, you know, met, and we can move forward.

So my next-door neighbour, who is a handyman, he really has a lot of expertise in this area. He's done little renovations throughout his entire house and for friends, and he did a walkthrough of the house before we moved back in. Seeing, you know, how much he appreciated all of those little details, the craftsmanship, the workmanship and everything, through his eyes, was really validating for me in terms of the entire project and process.

You know, you're always going to run into surprises when you tear down walls. And for me the most important thing is being able to communicate the surprises, being able to manage expectations, being transparent, and delivering on what you say you're going to do. And all of those conditions were met throughout the whole process.

I would hands down recommend Jarvis Contracting to someone.

# Bellamy, final day: a bungalow's main floor opened up

Video file: https://www.jarviscontracting.ca/media/video/bellamy-final-day.mp4 (78 seconds)

## Transcript

So we're here at Project Bellamy and it's the final day, my favourite day because that means we're all finished and the homeowner gets to move home. What you see around me is a modern organic design by Juliette Interiors and it was a collaborative effort between her and the homeowner. And let's take a look at the space.

So after speaking with the homeowners and Ceara taking them through their homework, we decided on a modern organic design. They really like the natural elements of stone and modern textures of the oak finishes. As well, we added these two nice arches behind us, which gives it that modern trend.

So one of the things we're most proud about this job is that we made the entire house completely safe. When we found asbestos, we got the right people to come in and remove it safely. When we found fire hazards, we took care of those.

Everything's now fully inspected and up to code, and the homeowners have nothing to worry about. So what sets us apart is that we're a fully custom builder, and we're able to add small details around the place that make a huge difference. For example, this hood is fully curved around the corners here.

The homeowners really love that look and it also ties into this farmhouse sink that has the curve as well. If you come over here to this shelf, as you can see it's backlit, but we also added this brass rail that helps stop cups from falling over and it just creates that personalised custom look that the homeowners love.

## Transcript

So whenever you're doing major renovations, it's inevitable you're going to have to solve some problems. And finding a contractor who can solve those problems quickly is the most important thing a homeowner can do. From the asbestos, to the fire hazards, to the point load in the basement, we had to tackle all these problems.

And we did so in such a timely manner, we didn't even increase the schedule. We delivered the final product on the date that we said we would.

## Transcript

So for this project we decided to use a luxury vinyl herringbone floor. Not only is it cost effective, it's very durable, but one thing is that it needs to expand and contract. So our transitions between different types of floors has to be a certain way.

We decided to use a solid wood vinyl overlap floor, stained to match the floor, and it provides a very luxury look. The design process of this home was very unique because although it's a very big project, we wanted it to feel very custom and detailed. So we brought a lot of those elevated detail designs throughout our molding on our cabinets, through the hardware that we used for these custom pocket doors, for the curves on our island, and also in the colours and textures that we've used throughout the home.

Lime washing the fireplace, an organic Taj Mahal stone for the fireplace that is mitered. We made very custom door designs for our TV area. So there's a lot of intricate design that went into this.

Intentional design was very important in the footprint of this home. Designing for a family of four, we had to make the space very functional, with lots of practicality in the storage, as well as focusing on the flow of the home. We wanted an island with an overhang.

We also wanted a spacious dining area. So we really had to work with that compact footprint in order to give our clients the best and the most of the storage.

So after 10 months of construction, we just completed Project Greenwood and we took this project through the permit process, interior design phase and the construction. There was a lot of collaboration between builder and designer and architect to really bring this project together. It was a very large project, so we really loved working with the homeowners and seeing this come to life.

So one of the greatest advantages of working with Jarvis Contracting is that we're a family business. We're husband and wife. There's always seamless communication.

# Orra: refinishing a stair so it matches the new floor

The stain on the finished Orra stair didn't match the new floor beside it. James explains why he refinished the whole stair anyway, and stands by his work.

## Transcript

So whenever you're doing a large-scale renovation like this, you're always going to come into some problems. One of those problems happened here on the stairs. We've already finished these stairs.

The homeowner did approve the colour of the stain. But after all the stairs were finished and we put our floor beside it, it doesn't match. And I'm not happy with the match.

The homeowner's not happy with the match. So as a contractor who cares about his final product and who wants to make sure everyone's happy at the end, I'm going to stand by my work and I'm going to rectify this situation and we're going to refinish these stairs to the perfect match.
