Step-by-step
Use the ZoLa Map
The Zoning and Land Use Application (ZoLa) at zola.planning.nyc.gov is the official NYC zoning map. Enter any address to see the zoning district, overlays, special districts, and land use designations.
Identify the Zoning District
ZoLa will show the zoning district code (e.g., R7A, C4-6, M1-2). Residential districts start with R, commercial with C, and manufacturing with M. The number and letter suffix determine density and building form.
Check for Overlays and Special Districts
Many areas have additional overlays (like commercial overlays on residential districts) or special district regulations. ZoLa highlights these. Special districts may impose additional requirements on height, setbacks, or use.
Review FAR and Building Envelope
The zoning district determines the Floor Area Ratio (FAR), which controls how much floor area can be built relative to the lot size. ZoLa shows the base and maximum FAR, height limits, and setback requirements.
Check Use Groups
Each zoning district permits certain use groups (there are 18 in NYC zoning). Verify that your intended use is permitted in the district. Some uses require special permits even in permitted zones.
Search Zoning with RegWatch
RegWatch displays zoning information as part of the property profile, including zoning district, FAR, lot coverage, and building class. Cross-reference with violations and permits for complete due diligence.
Overview
Zoning regulations in NYC control what can be built on every lot in the city. Understanding the zoning for an address is essential before purchasing property, applying for permits, or planning construction.
NYC Zoning Basics
NYC uses three main zoning categories: Residential (R), Commercial (C), and Manufacturing (M). Each has numbered subcategories that control density. Higher numbers generally allow greater density. Letters (A, B, X) indicate contextual or quality housing requirements.
Floor Area Ratio (FAR)
The FAR is the key metric in NYC zoning. It determines the maximum amount of floor area that can be built on a lot. For example, a 10,000 sq ft lot in a zone with FAR 2.0 allows up to 20,000 sq ft of floor area. Bonus FAR may be available through inclusionary housing or other programs.
Common Zoning Mistakes
Buyers and developers frequently make errors by assuming a property can be used for a purpose not permitted by zoning. Always verify zoning before committing to a purchase. A building currently used as a restaurant does not guarantee that restaurant use is permitted by current zoning, as it may be a pre-existing non-conforming use.
Frequently asked
Can I change the zoning of my property?
Individual property owners generally cannot change zoning. Zoning changes (rezonings) are initiated through a public process called ULURP. However, you may be able to obtain variances or special permits from the Board of Standards and Appeals (BSA) for specific uses.
What does FAR mean in NYC zoning?
FAR (Floor Area Ratio) is the ratio of total building floor area to lot area. A FAR of 2.0 on a 10,000 sq ft lot allows 20,000 sq ft of building floor area. It is the primary control on building density in NYC.
