Once You’ve Applied:

You’ve refined your project, done your research and submitted all the necessary documents to apply for your permits. Now what?

Once staff have verified your application is complete, it will be reviewed simultaneously by the different permitting departments. You may receive a call from a reviewer needing more information about your project. The faster you’re able to supply any additional documentation, the faster the total turnaround time will be. Currently, the average time it takes to issue the permit package is 10 business days.

A permit specialist will contact you when your permits are ready. All fees must be paid upon pick up before the inspection card and stamped drawings will be released. If you haven’t already, this is also the time to apply for any trade permits, such as electrical, mechanical and plumbing permits. These permits have separate fees that are dependent on the scope of work.

Once you have your permits in hand, you can begin construction! However, the process isn’t quite finished yet. You’ll need to schedule all applicable inspections as progress continues on your project. Be sure to continue on to Step 5: Schedule Inspections.
