Frequently Asked Questions

How do I look up a building permit in Brooklyn?

All NYC building permits are searchable through DOB NOW (the current system) and BIS, the legacy Buildings Information System. Search by address, BIN, block-and-lot, or permit number. Both portals are operated by the New York City Department of Buildings.

Who issues building permits in Brooklyn?

All five boroughs share a single issuing authority: the New York City Department of Buildings (DOB). Brooklyn does not have a separate borough-level building department.

What's the difference between DOB NOW and BIS?

DOB NOW is the modern online filing and search system. BIS is the legacy database - many older permits remain searchable only through BIS. New filings since approximately 2018 generally appear in DOB NOW; both systems are publicly accessible.

What is a Job Filing in NYC permitting?

A Job Filing is the application that initiates a building project; permits are issued underneath an approved Job Filing. A single Job Filing can cover multiple work types and often spawns several permits.

Are building permits public record in New York?

Yes. Permit records, job filings, complaints, and violations are all publicly accessible through DOB NOW and BIS without registration. NYC also publishes bulk permit datasets through NYC Open Data.

How long does a NYC permit take to issue?

Trade permits filed under an approved Job Filing can issue within days. Job Filings themselves require review by DOB plan examiners and typically take weeks to months depending on complexity, professional certification status, and Borough Office workload.
