Flatcheck NYC — free apartment background checks

Flatcheck is a free, instant, letter-graded background check for NYC apartment buildings — automatically, right on the StreetEasy listing you're already looking at. No account, no ads.

When you open a StreetEasy building or listing page, Flatcheck reads the address and drops a color-coded grade badge (A–F) onto the page, built entirely from public NYC Open Data:

• HPD violations — open and closed, by hazard class
• Bedbug filing history
• Executed evictions
• Housing complaints (per unit)
• The registered landlord on file
• Possible illegal fees under the NYC FARE Act, flagged from the listing's own fee text

Click the badge or the toolbar icon for the full report, and a link to a shareable web page for that building.

Why it exists: NYC renters make one of their biggest financial decisions with almost no information about the building. The public records exist — they're just scattered across city datasets no one has time to dig through. Flatcheck does it in one glance, before you sign.

Honest by design: when a data source is unavailable, Flatcheck shows the section as "unavailable" rather than pretending everything is clean. Missing data is never shown as good data.

Private by design: no accounts, no logins, no tracking of your browsing, no ads, no data sold. Flatcheck runs only on StreetEasy pages, and only reads the building address and fee text shown on the page you open.

Flatcheck reports public-record information and is not legal or financial advice. FARE Act flags are informational; verify before acting.
