Picture a building inspector's clipboard that never gets shorter. That's the situation at Flatbush Gardens, where NYC Dept. of Housing Preservation & Development data shows the property's housing development fund corporation carrying 12,419 open violations across just six buildings — more than 2,000 per building, on average. For context, a single serious "Class C" violation — think no heat, lead paint, or a busted lock on the front door — already triggers a legal obligation to fix within 24 hours.

Flatbush Gardens sits at the top of a list worth knowing. The ten landlords with the most open HPD violations in New York City right now account for more than 77,000 unresolved complaints between them, according to data from NYC Open Data. The runners-up are no small operations: Neighborhood Renewal Housing Development Fund Corp tallies 10,128 violations across 22 buildings, while Parkchester South Condominium Association — four buildings in the Bronx — has 8,587 open.

The numbers get stranger further down. "Name Not on File" — technically a landlord of record for 727 buildings — shows 7,744 violations. That entry is less a rogue operator than a bureaucratic gap: properties where ownership isn't properly registered with the city. If you're renting in one of those buildings and something breaks, good luck finding someone legally responsible.

NYC Housing Authority, which manages housing for over 300,000 residents, appears at number eight with 5,904 violations across 1,666 buildings — a per-building rate that's actually lower than most others on this list, though that's a low bar to clear.

What should a renter actually do with this information? First, look up your own building before you sign anything. HPD's violation database is public and searchable by address. A high violation count — especially a cluster of Class B or C items — signals both discomfort and legal leverage. Landlords with open violations are already on the city's radar, which means you have standing to push back, withhold rent in escrow, or file a complaint without being the first person to rock the boat.

Violations don't automatically mean a building is uninhabitable. But 12,000 of them at one address means somebody has been kicking problems down the road for a long time. For the latest on New York City renter news — including shifts in who's holding these records — it's worth checking back as the city updates its data. The clipboard isn't getting shorter on its own.
