About

NYC Building Report Card turns public city records about a building into one readable page, with every figure cited.

What this is

New York City publishes an enormous amount of information about its buildings — housing violations, tenant complaints, property assessments, ownership registrations, school zones. It is free and public, but it is spread across a dozen datasets that are indexed by a code almost nobody knows: the BBL, or borough-block-lot number.

This site does the joining for you. Enter an address, and it resolves the BBL, queries the relevant datasets live, and assembles a single report.

Who it is for

Renters checking a building before signing a lease.
Buyers doing diligence on a co-op, condo or small building.
Journalists and tenant organizers looking up owners and conditions.
Anyone who wants the public record on a building without a research project.

Where the data comes from

All of it comes from free, public sources. Nothing is scraped from private databases and no data is sold.

Housing violations and complaints — NYC HPD, via NYC Open Data.
Property valuation and assessment — NYC Department of Finance.
Building facts — PLUTO, published by the Department of City Planning.
School zones and state test results — NYC Department of Education.
Address to BBL resolution — NYC Geoclient.

Each report links back to the exact dataset behind every figure, so you can check it yourself.

What it deliberately does not do

It does not rate buildings. You will not find labels like "bad building" or "good school" here. It presents numbers and lets you interpret them.
It does not call assessed value a market value. Assessed value is what the city taxes against. DOF's own market estimate is shown separately, and the two are never combined.
It does not clear a building. A report with no open violations means only that none are on record in the datasets we query — not that conditions are good.
It does not sell your searches. There are no accounts and no tracking for advertising.

Accuracy and limitations

Data is shown as reported by the source agencies, including their errors and their reporting lags. Reports are cached for up to 7 days, so a fresh filing may not appear immediately. If something looks wrong, verify it against the linked source dataset — and tell us, so we can look at it.
