In Subdistricts A, B and C, and Subareas D1, D2 and D3 of the Hell’s Kitchen Subdistrict D, and Subdistrict E, the height and setback regulations set forth in paragraphs (a) through (d) of Section 93-42 (Height and Setback in Subdistricts A, B, C, D, E, F and G) shall apply, except that such regulations are modified in certain locations as set forth in this Section. Such modifications include the establishment of street wall location regulations, and minimum and maximum base heights, as shown on Map 3 (Mandatory Street Wall Requirements) of Appendix A of this Chapter. Such modifications also include depths of required setbacks, maximum length of building walls for towers, and tower lot coverage. Special provisions for recesses and sidewalk widenings are as follows:

(a)        Recesses

Where street walls are required to be located on street lines or sidewalk widening lines, ground floor recesses up to three feet deep shall be permitted for access to building entrances, and deeper recesses shall be permitted only where necessary to comply with the pedestrian circulation space provisions of Section 93-63. Above a height of 60 feet for buildings fronting upon 34th Street in Subdistrict C or above a height of 50 feet for buildings fronting upon Tenth Avenue in Subdistricts C and D, and up to any specified minimum base height, recesses are permitted provided that the aggregate length of such recesses does not exceed 30 percent of the length of the required street wall at any level, and the depth of such recesses does not exceed five feet. No limitations on recesses shall apply above any specified minimum base height or to any portion of a zoning lot where street walls are not required.

Where street walls are required to extend along the entire street frontage of a zoning lot, no recesses shall be permitted within 20 feet of an adjacent building, or within 30 feet of the intersection of two street lines, except where corner articulation rules apply.

(b)        Sidewalk Widenings

Where a street wall is required to extend along the entire street frontage of a zoning lot, and such street is intersected by a street with a mandatory sidewalk widening, no street wall shall be required within such sidewalk widening. Where corner articulation rules apply, the inner boundary of any required sidewalk widening may be considered to be the street line. The mandatory street wall requirements are illustrated on Map 3 in Appendix A of this Chapter. Where sidewalk widening lines are specified, such lines shall be parallel to and five or 10 feet from the street line, as required pursuant to Section 93-61 and illustrated on Map 4 (Mandatory Sidewalk Widenings) in Appendix A.

In Subdistrict F, the provisions of Section 93-41 (Rooftop Regulations) and Section 93-56 (Special Height and Setback Regulations in Subdistrict F) shall apply.

In Subdistrict G, the provisions of Sections 93-57 (Special Height and Setback Regulations in Subdistrict G) and 93-58 (Special Permit for Modification of Height and Setback Regulations) shall apply.
