§ 157.110  GENERAL PARKING REQUIREMENTS.
   Off-street parking in conjunction with all land and building uses shall be provided as herein prescribed.
   (A)   For the purpose of this ordinance, 300 square feet of lot area shall be deemed a parking space for 1 vehicle, including access aisle, except that the standard shall be 325 square feet where parking is perpendicular to the access aisle, and except that 180 square feet of lot area which has a direct means of ingress and egress from an alley or street may also be deemed a parking space.
   (B)   When units or measurements determining the number of required parking spaces result in requirement of a fractional space, any fraction up to and including 1/2 shall be disregarded and fractions over 1/2 shall require 1 parking space.
   (C)   The minimum number of off-street parking spaces shall be determined in accordance with the following table in § 157.111.  For uses not specifically mentioned therein, off-street parking requirements shall be interpreted by the Board of Zoning Appeals from requirements for similar uses.
   (D)   Any area once designated as required off-street parking shall never be changed to any other use unless and until equally required facilities are provided elsewhere.  Off-street parking existing at the effective date of this ordinance in connection with the operation of an existing building or use shall not be reduced to an amount less than would hereinafter be required for that building or use.
   (E)   The off-street parking may be provided either by individual action or by a parking program carried out through public action, whether by a special assessment district or otherwise.
   (F)   Required off-street parking shall be for the use of occupants, employees, visitors, and patrons and shall be limited in use to motor vehicles.  The storage of merchandise, motor vehicles for sale, or the repair of vehicles is prohibited.  All off-street parking, whether public or private, for nonresidential uses shall be either on the same lot or within 300 feet of the building it is intended to serve, measured from the nearest point of the building to the nearest point of the off-street parking lot.
   (G)   Residential off-street parking space shall consist of a parking strip, garage, or a combination thereof and shall be located on the premises it is intended to serve and not closer than 3 feet from any street lot line.
   (H)   Nothing in this ordinance shall be construed to prevent collective provision of off-street parking facilities for 2 or more buildings or uses, provided those facilities collectively shall not be less than the sum of the requirements for the various individual uses computed separately in accordance with the table.
   (I)   In stadiums, sports arenas, churches, and other places of assembly in which patrons or spectators occupy benches, pews, or other similar seating facilities, each 24 inches of the seating facilities shall be counted as 1 seat for the purpose of determining requirements for off-street parking facilities under this ordinance.
