If your permit is about to expire, and you know you will not be able to request and pass a required inspection prior to the expiration date, you can request a one-time extension. This extension can only be requested when the permit is still active and not expired. You will need to submit a Permit Application with the Permit Extension box checked in the Permit Request section. A minimum permit fee will be charged. Once a permit has expired it can only be extended with a renewal permit.
If your permit has expired and you have not completed all required inspections, you must first obtain a renewal permit to reopen the permit and then you can continue requesting all remaining inspections.
