Height and setback regulations
The underlying height and setback regulations shall not apply, except as set forth in Sections 23-62 or 33-42 (Permitted Obstructions), as applicable. In lieu thereof, the height and setback provisions of this Section shall apply. All height shall be measured from curb level.
(a) Street wall location
For zoning lots with wide street frontage, street walls shall be located on the wide street line and extend along the entire wide street frontage of the zoning lot. For corner lots with narrow street frontage, street walls shall be located on and extend along the narrow street line within 50 feet of the wide street.
For zoning lots with narrow street frontage, street walls shall be located on the street line and extend along the entire narrow street frontage of the zoning lot beyond 50 feet of a wide street. However, where the street wall of an adjacent building fronting on the same narrow street line is located within 10 feet of the street line, the street wall of the building may be aligned with the street wall of the adjacent building for a distance of not less than 20 feet measured horizontally from the side wall of such building. The portion of a zoning lot that is located between a street wall and the street line, pursuant to the optional street wall location provisions of this paragraph (a), shall be maintained at the same elevation as the adjoining sidewalk. In addition, such portion of a zoning lot shall be planted, except at the entrances to and exits from the building, or adjacent to commercial uses fronting on the street.
(b) Permitted recesses
Ground floor recesses up to three feet deep shall be permitted for access to building entrances. Above a height of 12 feet, up to 30 percent of the aggregate width of street walls may be recessed, provided no such recesses are within 30 feet of the intersection of two street lines.
(c) Building height
Within 100 feet of a wide street, the street wall of a building or other structure shall rise without setback to a minimum height of 50 feet or the height of the building, whichever is less, and a maximum height of 66 feet. A setback shall be provided for all portions of buildings that exceed a height of 66 feet. Such setbacks shall be provided at a height not lower than 50 feet and not higher than 66 feet, and shall have a minimum depth of 10 feet, measured from any street wall facing a wide street, and a minimum depth of 15 feet, measured from any street wall facing a narrow street. No building or other structure shall exceed a height of 85 feet. Beyond 100 feet of a wide street, no building or other structure shall exceed a height of seven stories or 66 feet, whichever is less.
However, the City Planning Commission, by special permit, may modify the special height and setback regulations set forth in this Section. In order to grant such special permit, the Commission shall find that the distribution of bulk permits adequate access of light and air to surrounding streets and properties and that the maximum height does not exceed 99 feet beyond 100 feet of a wide street, and 115 feet within 100 feet of a wide street.
The Commission may prescribe appropriate conditions and safeguards to protect and minimize any adverse effects on the character of the surrounding area.
