No existing use of land or structure shall be deemed to be a nonconforming use solely because of lack of off-street parking facilities or off-street loading facilities prescribed in the Chapter; provided, however, that facilities being used for off-street parking and off-street loading at the time of the adoption of this Code shall not be reduced in capacity to less than the number of spaces or berths or reduced to less than the minimum standards prescribed in this Chapter. Where an existing use is expanded, the parking requirements of this Chapter shall apply only to the addition. (Ord. 527, 8-4-1997)
