In the districts indicated, all permitted or required off-street parking spaces accessory to permitted non-residential uses may be provided on a zoning lot other than the same zoning lot as such uses, but within the same district or an adjoining district other than an Rl, R2, R3 or R4 District provided that in such instances all such spaces located in a Residence District shall be not further than 200 feet from the nearest boundary of the zoning lot containing such uses, and all such spaces located in a Commercial or Manufacturing District shall be not further than 600 feet from the nearest boundary of such zoning lot, and provided further that the Commissioner of Buildings determines that:
(a) there is no way to arrange such spaces on the same zoning lot as such uses; and

Such parking spaces shall conform to all additional regulations promulgated by the Commissioner of Buildings to minimize adverse effects on the character of surrounding areas.
