— Why this tool exists

The lookup is free. The product is monitoring.

A one-time lookup is a snapshot — a photo of your building's compliance state at this exact moment. It's useful for due diligence, for an acquisition memo, for answering a tenant question. And it should always be free.

The real value is continuous monitoring. Our detection engine keeps running after you close the tab — surfacing violations, 311 complaints, OATH hearings, and compliance deadlines the moment they exist, and routing them to the right person on your team before the default clock starts.

— Frequently asked

Questions about the lookup.

How do I check building violations in NYC for free?
Paste any NYC street address into the search above and run a free check building violations NYC search. The tool resolves the address to a BIN and pulls every open and historical violation across 10 agencies — DOB, HPD, ECB, OATH, FDNY, 311, DEP, DOH, PRM, and DOT — in a single query. No account required.
What does the NYC complaint lookup return?
The NYC complaint lookup returns every 311 complaint, HPD complaint, DOB complaint, FDNY NOV, ECB ticket, and OATH hearing tied to the address — sorted by routing agency with current status, recurrence count, and the original filing record.
Is the lookup really free?
Yes. Unlimited searches, no account, cancel anytime, no paywall later. The tool exists because the infrastructure that surfaces NYC compliance risk should be accessible to anyone who owns or manages a building here.
Do I need to sign up?
No. Enter an address, run the search, see every record. You only create an account if you want continuous monitoring — the product feature that watches the address for you after the search closes.
Where does the data come from?
Our multi-signal detection engine. We fuse agency records, inspection filings, complaint routing, adjacency patterns, and derivative indicators into a unified signal pipeline. Every result links back to the source filing so you can verify it against the official record.
How often is it updated?
Most signals refresh every 5 minutes. A handful of slower-moving datasets refresh on a longer cadence. Every result on the page shows its last-scan timestamp so you always know what you are looking at.
What if the address returns no results?
No results is a valid, good outcome — it means nothing currently appears in any of the 10 agencies for that BIN/BBL. If the address itself cannot be resolved, we will tell you and suggest the most likely canonical form.
Can I monitor this address continuously after I check building violations?
Yes. A one-click upgrade turns the same NYC complaint lookup into an always-on watch — alerts to your email, WhatsApp, or Slack the moment anything new lands for the address. The first 7 days are free.
