Two Separate Costs: Designer Fees vs. Municipal Fees
One thing that surprises many homeowners is that a building permit has two distinct costs:
- BCIN designer fees - what you pay to have the architectural and structural drawings prepared (the ranges above).
- Municipal permit fees - a separate, non-refundable fee paid directly to the city to process and review your application.
Municipal Permit Fees by City
Cities calculate their permit fee by the area or construction value of the project, so it scales with size. Typical residential ranges:
| Municipality | Typical Residential Fee | Basis |
|---|---|---|
| Toronto | $500 to $4,000+ | Per m² plus flat admin fees |
| Mississauga | $400 to $3,000+ | Per m² (minimum around $244) |
| Brampton | $350 to $2,500+ | Based on construction value |
| Markham / Vaughan | $300 to $2,500+ | Per m² of floor area |
| Hamilton | $300 to $2,000+ | Based on construction value |
What Drives the Drawing Price
Within each range, the price depends on complexity: the number of drawings, whether P.Eng structural engineering is required (for beams over 4.9 m, underpinning, or Part 3 buildings), site conditions, and whether you need a rush turnaround. A simple deck is at the low end; a two-storey addition with structural work sits at the high end.
The Real Cost of Skipping the Permit
Building without a permit is far more expensive than the fee. Municipalities can issue a stop-work order, require you to expose concealed work (even break open finished walls or poured footings) for inspection, and levy fines under the Building Code Act. Unpermitted work can also void an insurance claim and derail a home sale. If you already have unpermitted work, see how to legalize it.
