In all districts, as indicated, accessory off-street parking spaces, open or enclosed, shall be provided in conformity with the requirements set forth in the table at the end of this Section for all development after December 15, 1961, for the uses listed in the table. In addition, all other applicable requirements of this Chapter shall apply as a condition precedent to the use of such development.

After December 15, 1961, if an enlargement results in a net increase in the floor area or other applicable unit of measurement specified in the table in this Section, the same requirements set forth in the table shall apply to such net increase in the floor area or other specified unit of measurement.

A parking space is required for a portion of a unit of measurement one-half or more of the amount set forth in the table.

For the purposes of this Section, a tract of land on which a group of such uses is developed under single ownership or control shall be considered a single zoning lot.

For those uses for which rated capacity is specified as the unit of measurement, the Commissioner of Buildings shall determine the rated capacity as the number of persons which may be accommodated by such uses.

The requirements of this Section shall be waived in the following situations:

1. when, as the result of the application of such requirements, a smaller number of spaces would be required than is specified by the provisions of Section 25-33 (Waiver of Requirements for Spaces Below Minimum Number);
2. when the Commissioner of Buildings has certified, in accordance with the provisions of Section 25-34 (Waiver of Requirements for All Zoning Lots Where Access Would Be Forbidden) that there is no way to arrange the spaces with access to the street to conform to the provisions of Section 25-63 (Location of Access to the Street);
3. for houses of worship, in accordance with the provisions of Section 25-35 (Waiver for Locally Oriented Houses of Worship); or
4. for certain zoning lots, developments or enlargements below minimum thresholds pursuant to Section 25-37 (Waiver of Requirements for Certain Small Zoning Lots).

In the event that the number of accessory off-street parking spaces required under the provisions of this Section exceeds the maximum number of spaces permitted under the provisions of Section 25-18 (Maximum Spaces for Permitted Community Facility or Commercial Uses), the Commissioner of Buildings shall reduce the required number of spaces to the maximum number permitted.
