Building Permit Instructions

The permit expires if work authorized is not commenced within six months of the date of issue or if work is abandoned or suspended for a period of 6 months. If an extension is required, submit your request in writing indicating the reason for the delay in completion of the project. Keep in mind that a structure cannot be occupied until a Certificate of Occupancy is issued for a new structure.
