Toronto's Home Addition Contractor — Fixed Price, Permit Managed, On Time
Toronto's Home Addition Contractor
The average Toronto home addition goes over budget. Not because construction costs more than expected — because most contractors quote a number they know will win the job, then send change orders for everything that was never actually in scope.
BCF Contracting works differently. We are a Toronto home addition contractor that locks your price before we break ground. Your feasibility review, zoning analysis, permit application, and construction schedule are all managed under one fixed-price contract — one number that does not move unless you choose to add something.
We have completed second-storey additions, rear additions, and side additions across North York, East York, Etobicoke, Scarborough, and the GTA since 2010. Call us at 647-693-7479 to book your free property feasibility review.
Types of Home Additions We Build in Toronto
Second-Storey Additions
Add a complete upper floor to your Toronto bungalow or split-level. Structural engineering, permit management, and design-build coordination included. Most common addition type in North York and East York. We manage the full project while you stay in your home for most of the build.
Typical: $350K–$600K+
Rear Additions
Extend your main floor toward the rear property line to expand your kitchen, family room, or main-floor living space. Most cost-effective per square foot. Requires lot coverage and setback review — BCF manages both.
Typical: $250–$400/sq ft
Side Additions
Maximize your side-lot setback entitlement to add width to your home. Common in Toronto semi-detached properties. Zoning compliance review and variance support included where needed.
Site-specific — call for assessment
Garage Conversions
Convert an attached or detached garage into livable space — home office, accessory suite, or additional bedroom. BCF manages the full conversion including structural, mechanical, and finishes with full permit application.
Typical: $80K–$180K
What's Included in Every BCF Home Addition Contract
Most Toronto addition contractors charge extra for the things that matter most. At BCF, these are all standard:
✦ Free Lot Feasibility & Zoning Review ($1,500 value) — we assess your property and tell you exactly what is buildable before you commit to anything.
✦ Full Building Permit Application, Managed by BCF ($2,000+ value) — we handle the entire permit package, coordinate with your architect, respond to city comments, and schedule every inspection. You do not touch the city portal once.
✦ Committee of Adjustment Support Where Required — if your addition needs a minor variance, we coordinate the application. Included, not billed separately.
✦ Fixed-Price Contract — Locked Before Ground Breaks — every line item priced before you sign. Your cost only changes if you choose to add scope.
✦ Daily Progress via BuilderTrend — log in from your phone to see photos, schedule status, and budget in real time.
✦ 5-Year Structural + 1-Year Workmanship Warranty — in writing at handover.
This is the standard BCF contract. Every client gets this. Call 647-693-7479 to start your free feasibility review.

Home Addition FAQs — Toronto & GTA
How much does a home addition cost in Toronto?
Home additions in Toronto range from $250–$450 per sq ft for rear and side additions, and $350,000–$600,000+ for full second-storey additions. BCF provides a detailed fixed-price breakdown after your free feasibility review — no allowance guesswork. Call 647-693-7479.
How long does a second-storey addition take from start to finish?
Total timeline from first consultation to move-in is typically 9–14 months: 3–5 months for design, zoning, and permit approval, followed by 6–10 months of construction. BCF provides a complete project schedule at contract signing — every milestone known before ground breaks.
Do I need a building permit for a home addition in Toronto?
Yes. All structural additions require a City of Toronto building permit. Many also need a Committee of Adjustment minor variance if the addition exceeds zoning limits on lot coverage, setbacks, or height. BCF manages the full permit process on your behalf — included in your contract at no extra charge.
What if the project goes over the quoted price?
If something in the original scope costs more than estimated, BCF absorbs the difference. That is what a fixed-price contract means. Your cost only changes if you choose to add scope — which is always priced as a formal change order and approved by you before any work begins.
Can I stay in my home during the addition?
For most rear and side additions, yes — with some disruption during active construction phases. For full second-storey additions, we recommend 4–8 weeks of temporary accommodation during the structural open phase when the roof is removed. We advise this clearly during planning so you can arrange accordingly.
Which Toronto neighbourhoods do you build home additions in?
BCF builds home additions across all of Toronto including North York, East York, Etobicoke, Scarborough, Leaside, Leslieville, The Beaches, Lawrence Park, Forest Hill, Birchcliff, Swansea, and Roncesvalles — plus throughout the GTA including Mississauga, Vaughan, Richmond Hill, Markham, and Oakville.
