Zoning

R3-2

SRD

Low-Density Non-Contextual Residence District

R3-2 districts are general residence districts that allow a variety of housing types, including low-rise attached houses, small multifamily apartment houses, and detached and semi-detached one- and two-family residences. It is the lowest density zoning district in which multiple dwellings are permitted. Because of their flexibility, R3-2 districts are mapped widely in all boroughs except Manhattan.
