Notes about permits

• 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 $472.00 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

Finished basement fees
The finished basement fee does not include the creation of a new unit. 

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 $235, 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 $235, whichever is greater.

Additional Inspections
We may charge a fee of $235 for additional inspections if the inspection is not ready on a second attempt.

Engineering review cost recovery
