It shall be unlawful to use or occupy or permit the use or occupancy of any building or premises or both or part thereof hereafter created, erected, changed, converted, or wholly or partly altered or enlarged in its use or structure, until a certificate of occupancy required as part of the building permit procedure has been issued by the Zoning Inspector stating that the proposed use for the building or land conforms to the requirements of this Zoning Code. The issuance of a certificate of occupancy in no way relieves the recipient from compliance with all requirements of this Zoning Code and other regulations.
