NYC Zoning Handbook:
Residential Districts: R9
The city's R9 districts are mapped along some major avenues
and crosstown streets south of 96th Street in Manhattan. R9
zoning is not found in any other borough. The FAR ranges from
0.99 to 7.52, with density* ranging from 387 to 425 units per
acre. The higher FAR typically produces 17-story buildings
with low lot coverage that are set back from the street. R9
districts have the lowest open space requirement of any
residential district (except R10, where none is required).
Parking must be provided for 40 percent of the dwelling
units. The Quality Housing Program is optional in R9
districts.
*Density maximums (the number of dwelling units per acre) are
based on an average of 2 1/2 rooms per dwelling unit.
