R9 Zoning Code - New York City
What is an R9 Zoning District?
In R9 districts new buildings can be developed under height factor regulations or Quality Housing regulations, as in R6 through R8 districts. The optional Quality Housing regulations in R9 districts are exactly the same as the R9A regulations. Most R9 height factor buildings are developed pursuant to the tower rules, which are applicable only in the city's higher-density areas, including R9 districts and commercial districts with an R9 residential district equivalent (C1-8, C2-7 and C6-3).
R9 Height Factor/Tower Regulations: The floor area ratio for height factor/tower buildings in R9 districts ranges from 0.99 to 7.52 and the open space ratio from 1.0 to 9.0. As in other height factor districts, a taller building can usually be developed by providing more open space. Under the tower rules, however, buildings on both wide and narrow streets are permitted to penetrate the sky exposure plane. Buildings that front on a wide street must have a contextual street wall base of 60 to 85 feet with a tower above (tower-on-a-base). The height of the tower is controlled by a minimum lot coverage requirement and a rule that at least 55% of the floor area on the zoning lot be located below a height of 150 feet. For buildings with only narrow street frontage, a contextual base is not required and towers are permitted, provided they are set back from the street line at least 15 feet.
Parking is generally not required for any development in the Manhattan Core or Long Island City. Elsewhere, parking is required for 40% of dwelling units.
