* Except as provided in paragraphs (b) and (c) of this Section
** If the depth of a front yard exceeds 10 feet, the depth of the front yard shall be at least 18 feet. Furthermore, developments or enlargements pursuant to the optional regulations applicable in a predominantly built-up area shall provide a front yard with a depth of at least 18 feet. However, on a corner lot, if one front yard has a depth of at least 18 feet, the other front yard shall have a depth of at least 10 feet
Furthermore, if an opening to an accessory off-street parking space is located within the street wall of a building containing residences, there shall be an open area between the opening and the street line which is at least 8 feet, six inches in width by 18 feet in depth, except this provision shall not apply in R5D Districts.

(b) For the purpose of paragraphs (b) and (c) the area between the street line and the front building wall of adjacent buildings on the same or adjoining zoning lots shall be considered adjacent front yards.
Except as provided in paragraph (c) of this Section, in the districts indicated, if adjacent buildings containing residences on the same or on adjoining zoning lots fronting on the same street have front yards greater than the minimum set forth in paragraph (a) of this Section, then a front yard shall be provided which:
(1) in R1-2A, R2A, R3A, R3X, R4-1, R4A or R5A Districts is at least as deep as an adjacent front yard ; and
(2) in R4B, R5B or R5D Districts is no deeper than the deepest adjacent front yard and no shallower than the shallowest adjacent front yard.
However, a front yard need not exceed 20 feet in depth, except that in R1-2A Districts, a front yard need not exceed 25 feet in depth.
In determining the depth of the adjacent front yards, balconies and projections from the front building wall that do not exceed 33 percent of the width of the building shall be disregarded.
For developments or enlargements, projections into the required front yard are permitted provided that the width of all projections at the level of any story does not exceed 33 percent of the width of the building. The depth of such projections shall not exceed three feet into the front yard. However, balconies shall be subject to the provisions of Sections 23-13 (Balconies) and 23-44 (Permitted Obstructions in Required Yards or Rear Yard Equivalents).
(c) The provisions of paragraph (b) of this Section determining the depth of a front yard by the location of a front yard on an adjacent zoning lot, are modified as follows:
(1) on corner lots, these provisions shall apply on only one street frontage; and
(2) these provisions shall not apply to:
(i) any street frontage of a zoning lot where such frontage has a length of at least 150 feet along such street ;
(ii) any zoning lot located in historic districts designated by the Landmarks Preservation Commission; or
(iii) a frontage of any zoning lot where the depths of 50 percent of the front yards within 150 feet of the side lot lines of such zoning lot are shallower by more than two feet than the shallowest of the adjacent front yards.

(d) For any zoning lot located in a Historic District designated by the Landmarks Preservation Commission, the provisions of paragraphs (a) and (b) of this Section are modified as follows:
The depth of the front yard may vary between the requirements of paragraph (a) of this Section, or as modified in any applicable Special District, and the depth of the front yard of any adjacent zoning lot.
