Floor area preservation

The amount or configuration of floor area to be preserved may be modified in accordance with the provisions of Section 15-215 (Modification for existing dwelling units).

The amount of floor area to be preserved for permitted commercial or permitted manufacturing uses shall be in accordance with Table I of this Section, if the floor area to be converted is located in a C6-2M or C6-4M District, and in accordance with Table II of this Section, if the floor area to be converted is located in an M1-5M or M1-6M District, unless modified by the City Planning Commission pursuant to Section 15-51. Such floor area shall be comparable to the floor area to be converted, as required by Section 15-213.

Such floor area may be preserved in the building to be converted, or in any other building within the same mixed-use area, as defined in Section 15-21.

Except as provided in Section 15-215, floor area may not be preserved on portions of floors. If the floor area which must be preserved includes a fraction of a floor, the next highest number of full floors must be preserved for permitted commercial or permitted manufacturing uses. Floor area used for home occupations may not be used to meet the requirements of floor area and stories which must be preserved for commercial or manufacturing use. No accessory living or sleeping accommodations shall be permitted in the floor area preserved for permitted commercial or permitted manufacturing uses.

All requirements for preservation of floor area shall be determined by the entire lot area of the zoning lot, and by the total floor area of the building to be converted, regardless of the amount of floor area being converted within the building. For the purposes of this Section, any portion of the building to be converted that has a residential certificate of occupancy shall be excluded from the building's total floor area.

Any building that has been partially converted pursuant to Section 15-21 and has complied with the preservation requirements of such Section, shall not be required to preserve additional floor area for any subsequent conversion.
