311 Tracker
Free NYC building complaint lookup - 834,000 buildings
NYC's 311 system has no building-level search. 311tracker fixes that. Type any address → full complaint history, HPD violations, heat enforcement rate, and pest record. 834,400 buildings, updated daily. Free, no login. Original finding: 206,844 heat complaints closed as duplicates while conditions stayed open. Data sourced from NYC Open Data, verified against live API.
Hey Product Hunt 👋
Solo dev here, I built 311tracker because NYC renters have no easy way to check a building's complaint history before signing a lease — and landlords know it.
The official 311 site shows you individual complaints but gives you no building-level picture. I pulled all 1.9M complaints from NYC Open Data, built address-level pages for all 834,400 buildings, and set up a daily sync so it stays current.
While building it I found something interesting: 206,844 heat complaints were closed as "duplicates" — but the original complaints stayed open for years. HPD's own resolution text says "conditions still open" on closed complaints. That's the kind of thing that only shows up when you look at the data at scale.
Would love to know: if you were moving to NYC, what would you want to know about a building before signing?
Happy to answer any questions about the data or methodology.
