How Ontario Building Permit Fees Are Calculated
Ontario’s Building Code Act requires municipalities to collect permit fees — but how they calculate them is up to each municipality. There are three main methods used across Ontario:
| Method | How it works | Common in | Typical range |
|---|---|---|---|
| Per $1,000 of construction value | Fee = construction value ÷ 1,000 × rate | Most Ontario municipalities | $8–$22 per $1,000 |
| Per square metre of floor area | Fee = floor area (m²) × rate by occupancy type | Toronto, some larger cities | $15–$35 per m² |
| Flat fee by project type | Fixed amount regardless of size or value | Small municipalities, decks, pools | $150–$2,500 |
Construction value — who sets it?
You declare the construction value on your permit application. Municipalities often cross-check this against their own cost schedules (typically based on Ontario Building Officials Association guidelines). If your declared value seems low, they may recalculate using their schedule. Always 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 5–20× the permit fee, paid separately at permit stage
- Conservation authority fees — if your property is in a regulated area
- Entrance permit — if you’re creating or changing a driveway access
- Septic permit — separate approval for private sewage systems, administered by the health unit
- HVAC design / heat loss report — required for every new home permit in Ontario; see OntarioHeatLoss.ca for 48-hour delivery
- Engineering fees — structural, soils, or special conditions as required

How to Speed Up Your Permit Approval
The permit fee is just one piece of the puzzle. The bigger cost is usually time. Here’s 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.
- Confirm zoning before you draw — setbacks, lot coverage, height limits, and use restrictions can force expensive redesigns after you’ve paid for drawings.
- Include your heat loss report — Ontario Building Code requires a BCIN-stamped CSA F280 heat loss calculation for every new home. Missing this is one of the top causes of permit rejection. Get yours at OntarioHeatLoss.ca — 48-hour delivery, BCIN stamped.
- Show your structural logic — headers, beams, point loads, and spans must be clearly indicated or engineered. Reviewers ask about structure more than almost anything else.
- Respond to deficiencies fast — when you get a deficiency notice, fix the drawings and resubmit within days, not weeks.

Frequently Asked Questions
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 permit issuance, but this is 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 your application before significant review work has been done. Typically 80–90% is refundable early in the process, dropping to 50% once review has begun, and nothing after the permit is issued. Check your specific municipality’s refund policy — it’s usually in their permit bylaw schedule.
What happens if I underestimate the construction value?
Municipalities cross-check declared construction values against their own cost schedules (typically based on OBOA guidelines). If your declared value is significantly below their estimate, they’ll recalculate and charge the higher fee. Deliberately under-declaring is considered a misrepresentation on a legal document — not worth the small savings. Use a realistic number based on your builder’s quote or contract value.
Do I need a permit for a renovation in Ontario?
It depends on the scope. Cosmetic work (painting, flooring, cabinet replacement without plumbing changes) generally doesn’t need a permit. Structural changes (removing walls, adding openings, changing load paths), plumbing additions or relocations, HVAC changes, basement finishing with bedrooms or suites, and any additions all typically require permits. When in doubt, call your municipality and describe the scope — they’ll tell you. See our full guide: What Needs a Permit in Ontario?
Is the permit fee the same for ICF and wood frame construction?
Yes — permit fees are based on construction value or floor area, not the construction method. An ICF home and a wood frame home of the same size and value pay the same permit fee. The construction method does affect what documentation you need to include (ICF wall assemblies, for example, need clear thermal details), but not the fee itself. Learn more about building ICF in Ontario: ICFhome.ca.
What is a BCIN number and do I need one?
BCIN stands for Building Code Identification Number — it’s a registration number issued by the province to qualified building designers. For most residential projects, your designer (architect, engineer, or BCIN-registered designer) must include their BCIN on submitted drawings. Heat loss calculations for building permits also require a BCIN stamp — our sister service OntarioHeatLoss.ca delivers BCIN-stamped CSA F280 reports in 48 hours province-wide.

Builder’s note on permits
After 45+ years of building in Ontario, the permit process isn’t our enemy — it’s our quality assurance. The projects that go smoothest are the ones with clean, complete submissions and a builder who calls inspections on time and builds exactly what was approved.
