— TL;DR
The fastest way to pull DOB violations by BIN, BBL, or address — and how to cross-reference against OATH for the fine status each NOV resolves to.
01 · THE SHORT ANSWERHow to search DOB violations by address
To run a DOB violation search on any NYC building, start with the address — the city's systems resolve it to a BIN (Building Identification Number), then return every DOB violation, complaint, and permit on record. DOB runs two systems: BIS (the legacy Building Information System) and DOB NOW (the current platform). To see the fine attached to each violation, you cross-reference the related ECB/OATH record. Here's the full step-by-step.
02 · STEP 1Find the building
Everything keys off the building, not the street address. Enter the address into DOB's property search and it resolves to a BIN (unique to each building) and a BBL (Borough-Block-Lot, unique to the tax lot). A corner property or a multi-building lot can have several BINs — make sure you're looking at the right one.
03 · STEP 2BIS vs DOB NOW — what lives where
- BIS (Building Information System): the legacy system. Older violations, complaints, and historical permits live here.
- DOB NOW: the current platform for newer filings, permits, inspections, and many recent violations.
Because records are split across both, a manual DOB violation search means checking both systems. Looking at only one is the most common way owners miss an open item.
04 · STEP 3Read the results
A DOB violation search returns a few different record types — don't confuse them:
- DOB violations — issued directly by the Department of Buildings.
- ECB violations — issued by DOB but adjudicated at OATH, and the ones that carry monetary penalties.
- Complaints — reports (often 311-routed) awaiting inspection; not yet violations, but the early-warning layer.
- Stop-work orders — active halts on construction.
Check each item's status: open/active vs. resolved/dismissed. An old violation that was never certified-corrected stays open and follows the property into every sale and refinance.
05 · STEP 4Cross-reference OATH/ECB for the fine
A DOB violation tells you what's wrong; the OATH/ECB record tells you what it costs and when the hearing is. Look up the ECB violation number to see the hearing date, the penalty, and whether it has gone to default. Outstanding balances are payable through NYC CityPay. Skipping this step is how owners discover a default judgment months later.
06 · DOING THIS AT SCALEWhen one search isn't enough
A one-time search tells you what's open today. It says nothing about what's filed tomorrow. ViolationWatch's detection engine runs that DOB violation search continuously across BIS, DOB NOW, and the OATH layer — and alerts you the moment a new violation, complaint, or stop-work order appears on any building you watch.
