Ontario Building Permit Cost Calculator 2026
Estimate your building permit fee for any Ontario municipality – new homes, additions, renovations, decks, garages, and more. Built on real 2026 municipal fee schedules.
How this works: In Ontario, most municipalities charge a new-home permit by floor area – for example Collingwood at $1.17/ft2, Barrie at $17.38/m2, Toronto at $17.85/m2. Smaller projects (decks, sheds, basements) are usually flat fees. Pick your municipality, project type, and size for a realistic permit-fee estimate. Note: permit fees are separate from development charges – see our Development Charges Calculator for those.

How Ontario building permit fees are calculated
Ontario’s Building Code Act lets each municipality set its own permit fees, capped at the reasonable cost of administering the Code (Section 7). In practice there are three methods – and for new homes, floor area is the most common:
| Method | How it works | Common for | Typical range |
|---|---|---|---|
| Per m2 / per ft2 of floor area | Fee = floor area x rate (often by occupancy) | New homes, additions (most municipalities) | ~$12-$18 per m2 ($1.10-$1.70/ft2) |
| Flat fee by project type | Fixed amount regardless of size | Decks, garages, basements, pools, demo | $150-$600 |
| Per $1,000 of construction value | Fee = construction value / 1,000 x rate | A minority of municipalities; some add-ons | $8-$15 per $1,000 |
Floor area or construction value – who decides?
It depends on the municipality. Most price a new home by floor area (Collingwood $1.17/ft2, Barrie $17.38/m2, Toronto $17.85/m2). You still declare a construction value on the application; municipalities cross-check it against their own cost schedules (often based on Ontario Building Officials Association guidelines). Use a realistic number – the fee difference is small, but under-declaring can cause delays or legal issues.
What’s included in the permit fee – and what isn’t
The permit fee covers plan review and all required inspections during construction. It does not cover:
- Development charges – often 5-20x the permit fee, paid separately at permit stage. See the Development Charges Calculator.
- Conservation authority fees – if your property is in a regulated area. See conservation authority approvals.
- Entrance permit – if you’re creating or changing a driveway access.
- Septic permit – separate approval for private sewage (often $590-$760), administered by the municipality or health unit. See septic systems in Ontario.
- Heat-loss / energy report – a BCIN-stamped CSA F280 calculation is required for every new home permit; OntarioHeatLoss.ca delivers in 48 hours.
- Engineering fees – structural, soils, or special conditions as required. See when you need an engineer.
For a full breakdown of every cost before you build, see our Full Cost of Building in Ontario guide – it covers the soft costs that don’t show up in a builder’s quote.
Ontario permit fees by region – what to expect in 2026
These are building permit fees only for a typical ~2,000 sq ft new home – not development charges, which are separate and far larger.
| Region | Permit Fee (typical ~2,000 sq ft home) | Notes | Tag |
|---|---|---|---|
| Rural Simcoe County (Tiny, Tay, Clearview, Springwater) | $2,200 – $3,000 | Floor-area based; among the lower rates in the province | Rural |
| Collingwood, Wasaga, Midland (urban Simcoe) | $2,300 – $3,200 | Collingwood = $1.17/ft2; a 2,000 sq ft home is about $2,340 | Urban |
| Barrie (City) | $3,200 – $3,800 | $17.38/m2 incl. basement; a 186 m2 home is about $3,230 | Urban |
| Muskoka / Parry Sound | $2,000 – $3,000 | District municipalities; generally lower rates | Rural |
| GTA (York, Peel, Halton, Durham) | $3,000 – $4,500 | Higher per-m2 rates; some add technology surcharges | GTA |
| City of Toronto | $3,800 – $6,500 | $17.85/m2 + $54.16/unit + ~$620 zoning certificate | City |
How to speed up your permit approval
The permit fee is just one piece. The bigger cost is usually time. What consistently speeds up approvals in Ontario:
- Submit a complete application – incomplete submissions go to the back of the line. Every missing document restarts the clock. See what makes an application complete.
- Confirm zoning before you draw – setbacks, lot coverage, height, and use restrictions can force expensive redesigns. Start with the zoning decoder.
- Include your heat-loss report – a BCIN-stamped CSA F280 calculation is required for every new home. Missing it is a top cause of rejection. Get it at OntarioHeatLoss.ca – 48-hour delivery.
- Show your structural logic – headers, beams, point loads, and spans must be clearly indicated or engineered. See what permit drawings need to show.
- Respond to deficiencies fast – fix the drawings and resubmit within days, not weeks.

Frequently asked questions
How are Ontario building permit fees calculated?
Most Ontario municipalities charge a new-home permit by floor area – a rate per square metre or square foot, often varying by occupancy type. For example Collingwood charges $1.17/ft2, Barrie $17.38/m2 (basement included), and Toronto $17.85/m2 plus a per-unit charge and a zoning certificate. Smaller projects like decks, sheds, basements, and pools are usually flat fees. A minority of municipalities price by construction value (per $1,000). Every municipality sets its own schedule by by-law, so always confirm the current rate locally.
When is the permit fee paid?
In most Ontario municipalities the permit fee is paid at the time of application, before the permit is issued. Development charges are also typically collected at this stage. Some municipalities allow a deposit at application with the balance due at issuance, but that’s less common. Budget both costs together and have the funds ready before you submit.
Can I get a permit fee refund if my project is cancelled?
Partial refunds are possible in most municipalities if you withdraw before significant review work has been done. Typically 80-90% is refundable early, dropping to about 50% once review has begun, and nothing after the permit is issued. Check your municipality’s refund policy – it’s usually in the permit by-law fee schedule.
What happens if I underestimate the construction value?
Municipalities cross-check declared construction values against their own cost schedules (often based on OBOA guidelines). If your declared value is significantly below their estimate, they may recalculate – though for floor-area-based fees the declared value matters less. Deliberately under-declaring is a misrepresentation on a legal document and not worth the small savings. Use a realistic number based on your builder’s quote or contract value.
Is the permit fee the same for ICF and wood frame construction?
Yes – permit fees are based on floor area or construction value, not the building method. An ICF home and a wood-frame home of the same size pay the same permit fee. The method affects what documentation you include (ICF wall assemblies need clear thermal details), but not the fee. Learn more about building ICF in Ontario at ICFhome.ca.
Do I need a permit for a renovation in Ontario?
It depends on the scope. Cosmetic work (paint, flooring, like-for-like cabinets) generally doesn’t. Structural changes, new or relocated plumbing, HVAC changes, basement finishing with bedrooms or a suite, and any addition typically do. When in doubt, check our do-I-need-a-permit guide or call your municipality and describe the scope.
