NYC Zoning Lookup

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:

• Zoning district(s) — primary and split-lot designations
• FAR — residential, commercial, and community facility
• Building class and land use category
• Special districts and overlays
• Landmark status (individual and historic district)
• Development rights — remaining buildable FAR

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.
