Before an owner may cause a newly constructed building to be occupied, or has a change of occupancy as defined in the Building Code, he or she shall first obtain a certificate of occupancy from the Building Inspector. The Building Inspector shall issue an occupancy certificate upon completion of the building or prior to change of occupancy if the building is found to be in compliance with the city’s ordinances and state’s laws. No person shall permit a structure to be occupied without first obtaining an occupancy certificate as provided herein.
