Zohgo - NYC Zoning Explained

Short answer: To find the zoning district for any NYC address, open the city's free ZoLa map (zola.planning.nyc.gov), type in the address, and read the district label off the map — something like R5 , R6B , or C4-3 . That code is the key that unlocks everything you're allowed to build. If you'd rather skip the map and get the answer in plain English, the Zohgo zoning assistant looks it up for you and explains what it means, free. Why your zoning district is the first thing to find In New York, almost every question about a property — how big you can build, whether you can add a unit, what businesses are allowed, how tall you can go — is answered by its zoning district . Before FAR, before floor plans, before calling anyone, you need this one code. Everything else follows from it. Find it with ZoLa (the free city map) ZoLa (the Zoning & Land Use Application) is the NYC Department of City Planning's official map, and it's free to anyone. Go to zola.pl...

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...

Short answer: Since the City of Yes for Housing Opportunity took effect on December 5, 2024, many NYC homeowners can add an accessory dwelling unit (ADU) — a basement apartment, a garage conversion, or a small backyard cottage — but it is not allowed on every lot, and real limits apply. Here is the plain-English version. What is an ADU? An accessory dwelling unit is a second, smaller home on the same lot as your house. In NYC that usually means one of three things: a finished basement or cellar apartment , a converted garage , or a small backyard cottage (sometimes called a granny flat). What City of Yes changed Before, ADUs were largely off the table for most homeowners. City of Yes now permits them in one- and two-family homes across the city's lower-density districts — a major shift. The goal is to let owners add a rental unit or space for family without tearing anything down. The catch: it is not everywhere, and there are limits This is where people get t...

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 ...
