Frequently Asked Questions

When do I need a permit for finishing my basement? 

When any walls are constructed or electricity is added to the basement.

How long does it take to process my application?

If the permit application is complete and there are no problems with the plans, it will normally take 7 to 10 business days to complete the entire permitting process. Turn around times are estimates only and may vary depending on workload.

How long is my permit good for?

As long as work and inspections continue the permit will be valid. If the project is abandoned or inspections are not requested for a period of 180 days or more, the permit will expire. A new permit will have to be issued before work can be resumed.

Do I need to have my permit issued for me to start working on my basement?

Yes, you must have a permit in your possession before starting any work.

How much will my permit cost?

We do not have a set fee for basement finish permits. The valuation of your job is based on the square footage that is being finished. We then use the permit fee schedule that is in table 1-A of the 1997 U.B.C.

If my basement was finished without a permit, is there a way that I can still get a permit?

Yes. You would still need to follow all of the above procedures for obtaining a building permit. You may be assessed an investigation fee for the initial inspections that will be performed in your basement. During these first inspections for framing and electrical, the inspectors would assess the work that was already completed. If they discover any code deficiencies they will discuss with you what will be needed to correct the problem.
