In C1 or C5 Districts, for a term not to exceed five years, the Board of Standards and Appeals may permit off-street parking spaces accessory to residences or non-profit hospital staff dwellings to be rented for periods of less than one week, to persons who are not occupants of such residences or non-profit hospital staff dwellings, provided that such rental of spaces conforms to the provisions set forth in Section 36-46 (Restrictions on Use of Accessory Off-street Parking Spaces) and that the following special findings are made:

(a)        that the number of spaces to be rented or the location of access, thereto, is such as to draw a minimum of vehicular traffic to and through streets having predominantly residential frontages;

(b)        that the total number of spaces to be rented to non-residents does not exceed 100; and

(c)        that where the total number of spaces to be rented to non-residents exceeds 20, reservoir space is provided at the vehicular entrance to accommodate 10 automobiles or 20 percent of the spaces so rented, whichever amount is less.

The Board may impose appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area, including limitations on signs or requirements for the shielding of floodlights.

This Section shall not apply to the Manhattan Core where the regulations set forth in Article I, Chapter 3, shall apply.
