Violations are issued by inspectors. Complaints are what residents reported; a complaint alone does not mean a problem was found.

HPD housing code violations

“Closed” can mean the owner certified a repair, not that an inspector confirmed it.

Know your rights

Rules that apply to renters across New York City, not findings about this building. Each one names the law or rule it comes from.

Every renter

• Your landlord has to keep it livable

  Every lease in New York, written or spoken, comes with a promise that the apartment and shared areas are fit to live in and not dangerous to your health or safety. You can't sign that promise away.

  Official recordNY Real Property Law §235-b, checked Oct 19, 2026

• Put repair problems on the record

  A complaint to the city (311 in NYC) creates a dated record and can lead to an inspection. Those records are what PRA shows.

  Official recordNYC HPD / 311, checked Oct 19, 2026

• There's public money for repairs

  Owners can apply to city programs for repairs. J-51 lowers property taxes for renovating apartment buildings. HPD's lead program offers loans that can be forgiven, averaging $10,000 per apartment, for buildings built before 1960. Each program has its own rules.

  Official recordNYC Finance (J-51); NYC HPD owner resources, checked Oct 19, 2026

If your apartment is rent-stabilized

PRA can't tell yet which apartments are rent-stabilized. Ask the landlord, or check your lease.

• Apartment upgrades have a limit

  If your apartment is rent-stabilized, the owner can raise the rent to pay for work inside it, up to $30,000 of work. That's at most about $179 a month. For a vacant apartment the state approved first, the limit is $50,000, at most about $347 a month. These increases are permanent.

  Official recordNY HCR Fact Sheet 26 (rules since Oct 17, 2024), checked Oct 19, 2026

• Ask for the receipts

  If your apartment is rent-stabilized and your new rent includes an increase for apartment improvements, you can ask the owner for proof of the work by certified mail, when you're offered the lease or within 60 days of signing. The owner has 30 days to send it.

  Official recordNY HCR Fact Sheet 26, checked Oct 19, 2026

• Building-wide upgrades: 2% a year at most

  If your apartment is rent-stabilized, the state can approve a rent increase for work on the whole building, like a new boiler or roof. It's capped at 2% a year and comes off the rent after 30 years.

  Official recordNY HCR Fact Sheet 24, checked Oct 19, 2026

Ask for a repair

Fill in the blanks for a polite, dated message to the owner or manager. It names the problems, points to the law and asks for a date.

General information, not legal advice.

Who owns it

Who the records say owns and manages this building, how that changed, and what else those organizations appear on.
