We help renters make informed decisions using the same public data landlords already have access to.
311 Tracker gives New Yorkers a free way to look up any building's violations, complaints, landlord history, and rent stabilization status before signing a lease.
All data comes directly from NYC Open Data. We sync 311 service requests and HPD housing violation records daily.
We index 834,400+ buildings across all five boroughs, matched using the NYC Department of City Planning's PLUTO dataset.
