The off-street parking and loading provisions of this title shall apply as follows:
A.
For all buildings and structures erected and all uses of land established after the effective date of the ordinance codified in this chapter, accessory parking and loading facilities shall be provided as required by the regulations of the districts in which such buildings or uses are located.
B.
When the intensity of use of any building, structure or premises is increased through change of use, addition of dwelling units, gross floor area, seating capacity or other units of measurement specified in this title for required parking or loading facilities, parking and loading facilities as required in this title shall be provided for such increase in intensity of use. However, no building erected or use lawfully established prior to the effective date of the ordinance codified in this chapter shall be required to provide such additional parking or loading facilities unless the aforesaid increase in unit of measurement shall amount to at least 15%. Determination of the percentage of increase in units of measurement for required parking or loading facilities shall be based on the total increase which a building or use shall undergo after the effective date of the ordinance codified herein, whether such total increase occurs at one time or in successive stages.
C.
Whenever the existing use of a building or structure hereafter is changed to a new use, parking or loading facilities shall be provided as required for such new use. However, if the said building or structure were erected prior to the effective date of the ordinance codified herein, 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 provision of this title.
