The off-street parking and loading requirement of this Zoning Code shall apply as follows:
(a) For all buildings and structures erected and all uses of land established after the effective date of this Zoning Code, accessory parking and loading facilities shall be provided as required by the regulations of the districts in which such buildings or uses are located. However, where a building permit has been issued prior to the effective date of this Zoning Code, and provided that construction is begun within six months of such effective date and diligently prosecuted to completion, parking and loading facilities in the amounts required for the issuance of said building permit may be provided in lieu of any different amounts required by this Zoning Code.
(b) When the intensity of use of any building, structure or premises shall be increased through the addition of dwelling units, gross floor area, seating capacity or other units of measurement specified herein for required parking or loading facilities, parking and loading facilities as required herein shall be provided for such increase in intensity for use and for at least fifty percent of any existing deficiency in parking or loading facilities.
(c) Whenever the existing use of a building or structure shall hereafter be changed to a new use, parking or loading facilities shall be provided as required for such new use. However, if the building or structure was erected prior to the effective date of this Zoning Code, additional parking or loading facilities are mandatory only in the amount by which the requirements for the new use would exceed those for the existing use, if the latter were subject to the parking and loading provisions of this Zoning Code.
