Zoning
R8B
LH-1A
Medium-Density Contextual Residence District
Apartment buildings in R8 districts can range from mid-rise, eight- to ten-story buildings to much taller buildings set back from the street on large zoning lots. This high density residential district is mapped along the Grand Concourse in the Bronx and on the edge of Brooklyn Heights. R8 districts are also widely mapped in Manhattan neighborhoods, such as Washington Heights. New buildings in R8 districts may be developed under either height factor regulations or the optional Quality Housing regulations that often reflect the older, pre-1961 neighborhood streetscape.
