You can look up NYC zoning by address using RegWatch, which pulls data from the Department of City Planning (DCP):
NYC's zoning resolution — administered by the Department of City Planning (DCP) — controls what can be built, how tall, and for what use across every lot in the five boroughs. There are three basic zoning categories: Residential (R), Commercial (C), and Manufacturing (M), each with numerous sub-districts that specify density, height, setback, and use requirements.
Key zoning metrics include FAR (Floor Area Ratio), which determines the maximum buildable square footage relative to lot size, and building class, which describes the current use. Special districts, overlays, and landmark designations add additional layers of regulation.
RegWatch pulls zoning data from DCP and presents it alongside building characteristics and development context. For each property, the zoning tab shows:
This data is essential for developers evaluating sites, attorneys advising on land use matters, and investors analyzing development potential.
Zoning determines property value in NYC perhaps more than any other factor. A lot zoned C6-4 in Midtown Manhattan has vastly different development potential than one zoned R6 in a residential neighborhood. Unused development rights (air rights) can be worth millions. Zoning changes can dramatically increase — or decrease — property values overnight.
RegWatch makes this complex information accessible and actionable, combining DCP data with property tax records, building permits, and violation data for a complete picture.
Enter any NYC address into RegWatch to see the zoning district, FAR, overlays, landmarks, and development rights for that property.
FAR (Floor Area Ratio) is the ratio of a building's total floor area to the lot area. A FAR of 2.0 on a 10,000 sq ft lot means you can build up to 20,000 sq ft of floor area.
RegWatch shows individual landmark and historic district status for every property, pulled from the Landmarks Preservation Commission database.
Yes. RegWatch shows all DCP special purpose districts, overlays, inclusionary housing areas, and other zoning modifiers for every property.
Yes. RegWatch calculates remaining buildable FAR (development rights) by comparing the zoning FAR with the current building area for every property.
