(b) Moving. An application to move a building or structure or portion thereof to another location on the same lot or to another parcel, which does not comply with the requirements of the zoning district in which it is proposed to be located, shall not be approved unless the building or structure thereafter conforms to the regulations of the zoning district in which it is located.
