Where accessory off-street parking is required to be maintained for multiple dwelling residences pursuant to Section 25-211, the number of required accessory off-street parking spaces may be calculated pursuant to either paragraph (a) or (b) of this Section.
For the purposes of calculating the number of required parking spaces for any building containing residences, any fraction of a space 50 percent or greater shall be counted as an additional space, and for the purposes of applying such provisions to rooming units, three rooming units shall be considered the equivalent of one dwelling unit.
Any accessory off-street parking spaces serving a zoning lot in excess of the number required by this Section shall be considered permitted spaces and shall not be regulated by the provisions of Section 25-20, inclusive.
Previously approved applications The number of required accessory off-street parking spaces shall be the number of spaces that were required at the time of the development, enlargement or conversion, as applicable, unless it would no longer be required pursuant to the regulations in effect prior to December 5, 2024. Such calculation may include all applicable parking reductions, waivers, geographically based modifications, or modifications for specific uses. For the purpose of establishing this amount, the Department of Buildings may accept any historical evidence deemed appropriate by the Department of Buildings, such as construction documents, zoning analyses, or other documents submitted as an approved application for a building permit. Where a building was subsequently enlarged or converted after its development, this historical evidence must include materials indicating the most-recent parking requirement in effect for all dwelling units on the zoning lot prior to December 5, 2024.
Simplified reference table As an alternative to the method set forth in paragraph (a), the number of required accessory off-street parking spaces shall be the number of spaces set forth in this paragraph (b). The number of required off-street spaces shall be determined by the total number of dwelling units on a zoning lot existing prior to December 5, 2024 multiplied by the applicable parking requirement in Column A or B, as applicable. However, where the calculation results in a number of parking spaces less than or equal to the number in Column C, no parking spaces shall be required for residences on the zoning lot.
