NYC Zoning Explained: Districts, Use Groups and What You Can Build
How the NYC Zoning Resolution sorts every lot into residence, commercial and manufacturing districts, how the ten use groups work, and how to look one up.
By Seayora Editorial Team · Published · Facts checked · 4 min read
Short answer: New York City’s Zoning Resolution decides what can be built on every lot and what it may be used for. Each lot sits in a residence (R1–R12), commercial (C1–C8) or manufacturing (M1–M3) district, sometimes with a special purpose district on top. Use rules sort every activity into ten use groups, bulk rules cap floor area and height, and a lawful use that predates today’s rules can continue unless it stops for two continuous years.
Key takeaways
- Look up any lot’s district, commercial overlay and special district on the city’s ZoLa map, then read the Resolution for that district.
- Since June 2024 uses are sorted into ten use groups numbered I to X, such as Use Group II for residences and Use Group VI for retail and services.
- Floor area ratio caps how much floor space a lot may hold: from 0.5 in low-density areas to 18.0 in central locations, and higher in some special districts.
- A non-conforming use that is discontinued for a continuous two years can generally be replaced only by a conforming use.
What is the NYC Zoning Resolution?
The Zoning Resolution is the city’s zoning law. It has 14 articles and 11 appendices, plus 126 zoning maps that place every lot in a district. Article II regulates residence districts, Article III commercial districts and Article IV manufacturing districts; Articles VIII through XIV set out special purpose districts, which add their own rules to the underlying district. The online edition shows the date each section was last amended, which matters because the Resolution changes several times a year.
What do the district letters and numbers mean?
| District | Range | What it generally means |
|---|---|---|
| Residence (R) | R1 to R12 | R1–R5 are lower density, R6–R8 medium density and R9–R12 high density |
| Commercial (C) | C1 to C8 | C1 and C2 are neighborhood retail districts; C4 to C6 are the principal shopping and business districts; the others fill specialized roles |
| Manufacturing (M) | M1 to M3 | Light, medium and heavy manufacturing areas |
A suffix such as M1-2 marks a variation in permitted building scale; the NYC Zoning Handbook gives the example that an M1-2 district typically allows one or two more stories than an M1-1. A commercial overlay mapped over a residence district allows ground-floor shops on an otherwise residential block.
How do you look up the zoning for a property?
Enter the address, or the borough, block and lot, on ZoLa, the Department of City Planning’s zoning map. It shows the zoning district, any commercial overlay, any special purpose district and recent zoning changes for the lot. Then read the sections of the Resolution that apply to that district. A lot on a district boundary, on the waterfront or inside a special district can be governed by more than one set of rules, so read all of them before you rely on one.
What are use groups?
Use regulations say which activities may locate in each district. City of Yes for Economic Opportunity, approved by the City Council in June 2024, reorganized the Resolution’s uses into ten use groups numbered with Roman numerals (ZR § 12-10, last amended June 6, 2024). The handbook’s examples: Use Group II covers residences, Use Group VI retail and services, Use Group VII offices and laboratories, Use Group VIII recreation, entertainment and assembly spaces, and Use Group IX storage. Within the groups, use tables list more than 250 individual uses and the districts that allow each one, sometimes with conditions.
Certificates of occupancy issued before that change describe uses with the former numbered use groups, 1 through 18, so an older building record and a new filing can label the same use differently.
How much can you build on a lot?
Bulk regulations control a building’s size and shape, and the main tool is floor area ratio, or FAR: the floor area a building may contain divided by the area of its zoning lot. A 10,000-square-foot lot with a maximum FAR of 2.0 may hold 20,000 square feet of floor area. Maximum FARs run from 0.5 in low-density neighborhoods to 18.0 in central locations, and can rise higher in special purpose districts. Districts often set different maximums for residential, commercial and community facility uses, and add height, setback, yard and lot coverage rules (NYC Zoning Handbook).
What happens to a use the zoning no longer allows?
A lawful use that predates today’s rules is a non-conforming use, and it can generally continue. But under ZR § 52-61, if a non-conforming use of land with minor improvements is discontinued, or the active operation of substantially all the non-conforming uses in a building stops, for a continuous period of two years, the property may afterward be used only for a conforming use, and an intent to resume does not change that. The section has narrow exceptions. Check it before a long vacancy in, for example, a store on a residential block or housing in a manufacturing district.
What if your plans do not fit the zoning?
There are three routes. The Board of Standards and Appeals can grant a variance, but only after making every one of the five findings in ZR § 72-21; our guide to zoning variances in New York walks through them. Some uses are allowed by special permit or authorization where the Resolution provides one. And the zoning itself can be changed by a rezoning or text amendment, which goes through public review before the City Planning Commission and the City Council.
Zoning is only the first gate. Construction also needs Department of Buildings approval, and the building’s certificate of occupancy has to match its legal use; see the NYC certificate of occupancy guide.
Frequently asked questions
How do I find out how my NYC property is zoned?
Search the address or the borough, block and lot on ZoLa, the Department of City Planning’s zoning map. It shows the district, any commercial overlay and any special purpose district. Then read the Zoning Resolution sections for that district.
Can I open a store on the ground floor of my building?
Only if the zoning district, or a commercial overlay, allows that retail or service use on that floor. A change of use usually also needs Department of Buildings approval and an amended certificate of occupancy.
Does selling a building end its non-conforming use?
A sale does not by itself end a non-conforming use. Under ZR § 52-61, what ends it is the use being discontinued for a continuous two years, subject to the section’s exceptions.
