In the districts indicated, the applicable street wall location provisions of this Section shall apply. Such provisions shall apply to the portion of a street wall located below the maximum base height and before the required setback as set forth in Section 23-432 (Height and setback requirements). 

1. Line-up rules
   
   In R6B, R7B, and R8B Districts, the street wall of a building shall be located no closer to the street line than the closest street wall, or portion thereof, nor further from the street line than the furthest street wall, or portion thereof, of an existing adjacent building on the same or an adjoining zoning lot located on the same street frontage. Eligible adjacent buildings shall be located within 15 feet of the street line, within 25 feet of the subject building, and have a height that exceeds 35 feet. Where an existing adjacent building has multiple street walls located at varying depths from the street line, the subject street wall shall not be located closer to the street line than the furthest portion of such existing adjacent street wall that is at least five feet in width and extends to at least half the height of the building.
   
   However, where, the street wall surrounding the subject building do not have a prevailing street wall frontage, the applicable street wall regulations of paragraph (b) may be applied.
2. Percentage-based rules
   
   For all buildings that are not subject to the provisions of paragraph (a), the following shall apply:
   1. Along wide streets, at least 70 percent of the aggregate width of street walls shall be located within eight feet of the street line and extend to at least the minimum base height specified in Section 23-432, or the height of the building, whichever is less. Up to 30 percent of the aggregate width of street walls may be recessed beyond eight feet of the street line, provided that any such recesses deeper than 10 feet along a wide street or 15 feet along a narrow street are located within an outer court.
   2. Along narrow streets, at least 70 percent of the aggregate width of street wall shall be located within 10 feet of the street line and extend to at least the minimum base height specified in Section 23-432, or the height of the building, whichever is less. Up to 30 percent of the aggregate width of street walls may be recessed beyond 10 feet of the street line, provided that any such recesses deeper than 15 feet are located within an outer court.
       

                   However, where the street walls surrounding the subject building are located on a block with a prevailing street wall frontage that is located further from the street line than the applicable provisions of this paragraph, the line-up provisions of paragraph (a) of this Section may be applied. 

3. Modifications for large zoning lots
   
   Notwithstanding the provisions of paragraph (a) or (b) of this Section, for zoning lots with a lot area of at least 40,000 square feet or for zoning lots that occupy an entire block, at least 50 percent of the aggregate width of street walls shall be located within 15 feet of the street line and extend to at least the minimum base height specified in Section 23-432, or the height of the building, whichever is less.
4. Articulation allowances
5. In all districts, and along all frontages, street wall articulation, including, but not limited to, window recesses and structural expression on the building facade, shall be permitted to project or recess beyond the street wall locations established in paragraphs (a), (b) or (c) of this Section, provided such articulation does not exceed a depth or projection of 12 inches. In addition, to accommodate other forms of street wall articulation, such as bay windows, and facade recesses, up to 50 percent of the aggregate width of street wall, at any level, may recess or project beyond such street wall location provisions of this Section, provided that no such recess or projection exceeds a depth of three feet, as measured perpendicular to the street wall, or portion thereof. No projection shall extend beyond the street line, except where encroachments into the public right-of-way are permitted by the New York City Administrative Code.
