ZoLa NYC: How to Use the Zoning & Land Use Map

ZoLa is the city’s free zoning and land use map. Click any lot in the five boroughs and it tells you what zoning district governs it, what overlays and special districts apply, and what the parcel is. It is the fastest way to answer what can be built here, and it costs nothing.

It lives at zola.planning.nyc.gov, run by the Department of City Planning.

What you get from one click

Select a lot and the panel returns the zoning district, any commercial overlay, any special purpose district, the borough, block and lot, and links out to the city’s other property systems.

That BBL is worth grabbing while you are there, because every other city database keys on it. See what a BBL is.

Reading a zoning district code

New York districts start with a letter that sets the basic use.

R is residential, C is commercial, and M is manufacturing. The number after it sets intensity, so R1 is the lowest density residential and R10 the highest. A further digit after a dash, as in R6A or R8B, refines the built form, controlling things like height, setbacks and where the building sits on the lot.

So R6A is a medium density residential district with a contextual form, and C2-4 is a commercial overlay of a particular intensity. You do not need to memorise the table. You need to know that the letter sets the use, the first number sets the density, and the suffix controls the shape.

Overlays and special districts

A commercial overlay, drawn as a C1 or C2 band over a residential district, permits local retail on what is otherwise a residential street. It is why a corner store exists in the middle of a residential block.

A special purpose district layers extra rules on top of the base zoning, covering things like ground floor use, streetwall height or design controls in a specific neighbourhood. If one applies to your lot, the base district alone will not tell you what is allowed.

ZoLa also shows historic districts and landmarked properties, which is a separate approval process entirely and one that catches renovation plans by surprise.

Buying or transferring this property?

Once the paperwork is ready, we notarize the deed and file it through ACRIS with the transfer tax forms, from intake to recorded confirmation.

FAR, the number people actually want

Floor area ratio is the multiplier that determines how much building you get. An FAR of 2.0 on a 2,500 square foot lot allows roughly 5,000 square feet of floor area, subject to every other rule about height, setbacks, yards and coverage.

Two cautions. FAR is a ceiling, not a promise, and the other bulk rules frequently prevent you from reaching it. And unused development rights can sometimes be transferred between adjacent lots, which is why a small building next to a tall one is not always an accident.

Who uses this and why

Buyers checking whether a property can be extended, converted or subdivided before making an offer.

Owners planning an addition and wanting to know the constraints before paying an architect.

Sellers confirming whether unused development rights add value.

Neighbours trying to understand what the construction next door is permitted to become.

Anyone confirming they are looking at the right parcel, since ZoLa shows lot boundaries clearly and corner and merged lots are easy to misidentify from an address alone.

What ZoLa cannot tell you

Whether a specific project will be approved. Zoning sets the envelope, and the Department of Buildings reviews the actual application.

Whether existing conditions are legal. Many buildings predate current zoning and are lawfully non conforming, which is a status you confirm through DOB records, not the map.

Who owns it, or what is recorded against it. That is ACRIS and Finance and HPD records.

Housing violations, which are on HPD Online.

Anything binding. ZoLa is an informational map, and for a decision that involves money you confirm with the Department of City Planning, the Department of Buildings, or a zoning attorney or expediter.

A sensible order to check things

Start with ZoLa for the zoning and the BBL. Move to ACRIS for the deed, mortgages and liens. Check HPD Online for violations and the registration if it is residential. Check the Department of Buildings for permits and open jobs. Then, if you are transacting, order a title search.

That sequence takes under an hour and answers most of what a buyer needs before spending real money. See the title search guide.

Frequently asked questions

Is ZoLa free?

Yes, and no account is needed.

Does ZoLa cover Staten Island?

Yes, all five boroughs. Note that Staten Island recorded documents are searched through the Richmond County Clerk rather than ACRIS.

Can I rely on ZoLa for a filing?

Treat it as a starting point. Confirm with the relevant agency before filing or purchasing.

What does R6A mean?

A medium density residential district with contextual bulk rules governing height and setback.

How do I find development rights?

Start with the district FAR and lot area, then have an architect or zoning professional run the actual calculation.

Non conforming uses and buildings that predate the rules

A great many New York buildings do not comply with the zoning that currently applies to them, and that is not necessarily a problem.

A building lawfully constructed under earlier rules can continue as a legal non conforming use or with non complying bulk. It exists as of right, but the protection is narrower than owners assume. Expanding it, or in some cases discontinuing the use for a period, can forfeit the status.

ZoLa will not tell you whether a building holds that status. It shows what the zoning is today. Establishing what a building is lawfully permitted to be is a Department of Buildings records question, usually starting with the certificate of occupancy.

The certificate of occupancy is the other half

Zoning says what may be built. The certificate of occupancy says what the building is legally allowed to be used as, and how many units it may contain.

Mismatches matter. A building operating with more units than its certificate permits has a real problem that surfaces at financing and at sale, and no amount of zoning research reveals it. Pull the certificate of occupancy from the Department of Buildings alongside your ZoLa search.

Before you rely on any of it

ZoLa is an informational map maintained by the Department of City Planning. It is excellent for orientation and it is not a determination.

For anything involving money, confirm with City Planning or the Department of Buildings, and for a project of any size involve a zoning attorney, an architect or an expediter. The cost of that advice is small next to the cost of designing around an assumption that turns out to be wrong.
