In all districts, other than districts with an A suffix, if the front wall or any other portion of a building or other structure is located at the street line or within the initial setback distance as set forth in the table in this Section, the height of such front wall or other portion of a building or other structure, except as otherwise set forth in this Section, shall not exceed the maximum height above curb level set forth in the table. Above such maximum height and beyond the initial setback distance, the building or other structure shall not penetrate the sky exposure plane set forth in the table.

The regulations of this Section shall apply, except as otherwise provided in Sections 43-42 (Permitted Obstructions), 43-44 (Alternate Front Setbacks) or 43-45 (Tower Regulations). In M1-1 Districts, for community facility buildings, the maximum height of a front wall shall be 35 feet or three stories, whichever is less, and the height above the street line shall be 35 feet, and in M1-4 Districts, for community facility buildings, the maximum height of a front wall shall be 60 feet or six stories, whichever is less.

For zoning lots in M1-6 Districts that are both within 100 feet of the western street line of Seventh Avenue and between West 28th and West 30th Streets in the Borough of Manhattan, the following street wall regulations shall apply to street frontages not occupied by a public plaza. The street wall of a building shall be located on the street line and extend along the entire street frontage of the zoning lot up to a minimum height of 125 feet or the height of the building, whichever is less, and a maximum height of 150 feet. Above a height of 150 feet, no portion of a building may penetrate a sky exposure plane except for towers, pursuant to Section 43-45. The sky exposure plane shall begin at a height of 150 feet above the street line and rise over the zoning lot at a slope of 5.6 feet of vertical distance for each foot of horizontal distance on a wide street, and at a slope of 2.7 feet of vertical distance for each foot of horizontal distance on a narrow street. The provisions of Section 43-44 shall not apply. On the ground floor, recesses shall be permitted where required to provide access to the building, provided such recesses do not exceed three feet in depth as measured from the street line. Above the level of the second story, up to 30 percent of the aggregate width of street walls may be recessed beyond the street line. However, no recesses shall be permitted within 20 feet of an adjacent building and within 30 feet of the intersection of two street lines.
