FAQ
Frequently asked questions
Are New York building permits public record?
Yes. Building permits issued by New York jurisdictions are public records. Each one publishes them in its own format and its own system, which is why a statewide view requires collecting and standardizing them jurisdiction by jurisdiction.
How do I look up a building permit in New York?
For a single property, the issuing jurisdiction's permit portal is the place to start, since permits are issued locally rather than by the state. For many properties at once, or for analysis across jurisdictions, a standardized dataset is the practical route: Builty holds 5.0M+ New York permit records in one consistent structure.
How far back does New York permit data go?
New York carries sustained coverage from 1995 to the present. Individual jurisdictions reach back further, and some records carry placeholder dates from legacy systems; those are identified as placeholders, so the stated window is the one the data actually supports.
Which New York jurisdiction has the most building permits?
New York City, at roughly two thirds of all state records. Yonkers and Poughkeepsie are the largest streams outside the city.
Are all five boroughs covered?
Yes. New York City permits across all five boroughs arrive through the city's own systems and are collected as one jurisdiction, matching how the city issues them.
Can I get data for a single county or city?
Yes. Delivery can be scoped to any set of New York jurisdictions, project types, or date ranges, by API, bulk file, or ongoing feed.
