Notes about permits

Special Permit I
We will double the permit fee if construction starts before a permit is issued:

if this amount exceeds $5,000, the penalty will incrementally decrease from 100% of the original permit fee to 15% of the original permit fee
the incremental decrease will only apply if the original permit fee amount is between $5,000 and $67,000
permit fees over $67,000 will pay 15%

Conditional permits
We will charge a fee of $421.48 plus $0.08/sq. ft. of the area for a conditional permit. You must submit an additional deposit in the form of a certified cheque or letter of credit to the Chief Building Official. The Chief Building Official will determine the amount of the deposit.

Shell permits
Shell permits include mechanical and electrical rough-ins.

Foundation permits
Foundation permits limit work to footings and foundation walls and the installation of underground plumbing, water supply piping and sewers to property line.

Occupancy Permit
If the Ontario Building Code requires an occupancy permit, the original permit fee will include it. You can request an additional copy of the occupancy permit for $63.

Transfer of permit
You must pay the minimum fee if ownership of a property changes and the permit is transferred.

Revision to examined plans
If the original building permit fee is more than $210, we will charge a fee for the examination of revised plans. The fee will be $0.01/sq. ft. of the revised floor area or $210, whichever is greater.

Affordable housing development
The city may offer a grant to cover or offset building permit fees, as approved by council (until the city's Affordable Housing Grant policy, currently under development, comes into effect).

Minimum Fee
We charge a minimum fee of $105 for any permit application.

Additional Inspections
We may charge a fee of $210 for additional inspections if the inspection is not ready on a second attempt.

Engineering review cost recovery
If the Chief Building Official (CBO) decides a third-party review is needed for Part 4 designs from a designer, the designer will need to pay the full cost of that review. This is on top of the regular building permit fees.
