How to Read a NYC Zoning Map (ZoLa) Step by Step

Short answer: ZoLa (zola.planning.nyc.gov) is the city’s free official zoning map. Type in any NYC address and it shows you the property’s zoning district, any commercial overlay, and any special district — the three things that together tell you what you’re allowed to build.

What is ZoLa?

ZoLa stands for the Zoning and Land Use Application. It’s the NYC Department of City Planning’s free, interactive online map, and it’s the same map most professionals open first when they start looking at a site. There’s no login and nothing to install — you just go to zola.planning.nyc.gov.

Step 1 — Look up your address

Type your street address into the search bar at the top. (If you know it, you can also search by BBL — the Borough, Block, and Lot number.) The map zooms straight to your property and highlights the lot.

Step 2 — Read your zoning district

The colored area sitting over your lot is your zoning district, labeled with a code like R5, R6A, C4-4, or M1-1. The first letter is the big-picture category:

  • R = Residence district
  • C = Commercial district
  • M = Manufacturing district

Click directly on your lot and ZoLa opens a panel with the details — the district, the lot dimensions, and links to the relevant rules.

Step 3 — Check for a commercial overlay

Some residential blocks have a commercial overlay stacked on top of the base district. On the map it shows up as a hatched or striped band along the street, labeled something like C1-2 or C2-3. An overlay is what allows local stores, restaurants, and other neighborhood retail on the ground floor of an otherwise residential block. If there’s one on your lot, it matters for what uses are allowed.

Step 4 — Check for a special or historic district

Use the layer menu to turn on special purpose districts and historic districts. If your lot falls inside one, an extra layer of rules applies on top of your base district — and those rules can change heights, uses, or even what your building has to look like. It’s an easy thing to miss and an important one to catch early.

Step 5 — Note the other layers that matter

ZoLa also maps things that quietly affect what and how you can build: floodplain and coastal zones, waterfront areas, and community district boundaries. If your property is near the water or in a flood zone, flip those layers on so nothing surprises you later.

What ZoLa tells you — and what it doesn’t

ZoLa is excellent at answering “what are the rules on this lot?” — the district, the overlays, the special districts. What it does not do is the math: it won’t calculate your FAR, your buildable square footage, or tell you “here’s what you can build.” For that, you take the district code and go read the Zoning Resolution — or you let a tool do the reading for you.

Every NYC lot is a little different, and the rules stack on top of each other. If you want to skip the guesswork, try Zohgo free at zohgo.ai — enter your address, tell it what you’re hoping to do, and it walks you through what may be possible for your specific lot.

This article is general information about NYC zoning, not legal advice. Zoning rules have many exceptions and change over time. Always confirm the specifics for your property with the current Zoning Resolution, the NYC Department of City Planning, or a licensed architect or zoning professional before making decisions.

How Many Units Can You Add to Your NYC Home Under City of Yes?

Short answer: It depends on your lot and zoning district — but since the City of Yes for Housing Opportunity took effect on December 5, 2024, most NYC homeowners have more ways to add a unit than they did before. Here is what actually changed, in plain English. What City of Yes changed for homeowners City of Yes for Housing Opportunity was the city's biggest zoning overhaul in more than 60 years. A lot of it is aimed at large developers — but three parts matter directly if you own a house and want to add living space or a rental unit. 1. Accessory Dwelling Units (ADUs) — the big one This is the change most homeowners care about. City of Yes now permits accessory dwelling units — a finished basement apartment, a converted garage, or a small backyard cottage — in one- and two-family homes across the city's lower-density districts. It is not automatic or unlimited. There are restrictions on size, placement, and which lots qualify, and the City Council ...

What Can You Build on Your NYC Lot? A Plain-English Guide

Short answer: What you can build on a NYC lot comes down to five things — your zoning district , how much floor area you’re allowed (your FAR ), how much of the lot you can cover, how tall you can go, and what uses are permitted. Two lots on the same block can have completely different answers. Here’s how to read your own lot, in plain English. Start with your zoning district Every lot in NYC sits in a zoning district — a residential ( R ), commercial ( C ), or manufacturing ( M ) district, usually with a number and sometimes a letter, like R4, R6B, or C4-3A. That short code is the master key: it drives almost everything else — how big, how tall, and what the building can be used for. You can look yours up for free on the city’s official map, ZoLa (zola.planning.nyc.gov), just by typing in your address. How much you can build — FAR FAR (Floor Area Ratio) is the single most important number. It’s the ratio between a building...
