Brooklyn CB6
Land Use & Zoning
Zoning Code Decoder

NYC zoning codes follow a consistent logic. The letter tells you the district type. The first number tells you the family — higher generally means more density. Numbers after the hyphen indicate subdistrict levels. Letters at the end (A, B, D, X) specify contextual or mapped variants.

RResidential
CCommercial
MManufacturing
A / BContextual suffix — keeps new buildings in scale with existing neighborhood fabric
DVariant — in M1-D districts, residential use may be permitted under stated conditions
XContextual with different form configuration than A
Example: R6A = Residential (R), mid-density family (6), contextual suffix (A).
Example: M1-4/R7A = Light manufacturing framework (M1-4) paired with contextual mid-rise residential (R7A).
Rule of thumb: The letter tells you the framework. The number tells you the density. The suffix tells you the form.
