For zoning lots within the Transit Zone with buildings containing income-restricted housing units in receipt of a certificate of occupancy prior to March 22, 2016, the Board of Standards and Appeals may permit a waiver of, or a reduction in, the number of accessory off-street parking spaces required for such income-restricted housing units prior to March 22, 2016, provided that the Board finds that such waiver or reduction will:

(a)        facilitate an improved site plan;

(b)        facilitate the creation or preservation of affordable housing, where a development includes new residential floor area on the zoning lot;

(c)        not cause traffic congestion; and

(d)        not have undue adverse effects on residents, businesses or community facilities in the surrounding area, as applicable, including the availability of parking spaces for such uses.

Factors to be considered by the Board may include, without limitation, the use of the existing parking spaces by residents of the zoning lot, the availability of parking in the surrounding area and the proximity of public transportation. The Board may impose appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area.
