Churches, theaters, banquet halls, and other similar uses, the parking requirements for which are likely to occur during hours other than ordinary business hours, may provide not more than 50% of the required parking space through the use of parking spaces provided by adjacent buildings and uses which do carry on the major portion of their business during ordinary business hours, provided the nearest boundary of said parking area is within 500 feet of the church, theater, bowling alley, banquet hall or similar use and provided further that the owner of said adjacent parking space notifies the Zoning Enforcement Officer in writing prior to the granting of any building permit to said church, theater, bowling alley, banquet hall or other business that said church, theater, bowling alley, banquet hall or other business may use said adjacent parking lot during other than ordinary business hours. Revocation of such permission by the owner of said adjacent parking lot shall be sufficient cause to revoke a building permit issued in reliance on said permission, or to refuse a Certificate of Occupancy, and if a Certificate of Occupancy has already been issued when such permission is revoked, said church, theater, banquet hall or other business shall immediately conform to the requirements of 7.01 hereof or be subject to the penalty provided by the General Statutes for the maintenance of a use in violation of the Zoning Regulations.
