It shall be unlawful for any owner to initiate construction or to use or to permit the use of any structure, building, or land, or part thereof, that is created, erected, changed, converted, or enlarged, wholly or partly, until a zoning permit, which may be a part of the building permit, shall have been issued by the Zoning Administrator. Such zoning permit shall show that such building or premises or a part thereof, and the proposed use thereof, are in conformity with the provisions of this Zoning Code. It shall be the duty of the Zoning Administrator to issue a zoning permit, provided they are satisfied that the structure, building, or premises, and the proposed use thereof, conform with all applicable requirements of this Zoning Code.
