A difference between the DHCR rent-stabilized count and the PLUTO total is common and does not, on its own, indicate a violation: units can leave rent stabilization legally, the two datasets count units differently, some units may be non-residential, and a registration can be filed incompletely. To check your own apartment, see how to request your rent history from DHCR.

- City records show 178 open HPD violations, 79 immediately hazardous (Class C) at this building. Ask which are still unresolved in the unit and the landlord’s timeline to clear them.
- The oldest open violation on record dates to 2002 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists no rent-stabilized units in this building. If anyone tells you this unit is stabilized, ask to see the registration — and if it was deregulated, ask on what grounds and in what year.
- City Buildings Department records show an open life-safety condition (e.g. unsafe building / hazardous facade) — what is it, and has it actually been resolved, not just re-filed?
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Owner failed to file a valid registration statement with the department as required….
- Confirm in person that the immediately-hazardous (Class C) conditions — typically heat, hot water, leaks, mold or pests — are genuinely fixed, not just marked closed.

Building Condition
Oldest open violation: July 2002 · Most recent: May 2026. HPD marks a violation open until it is certified as corrected, so an old date can mean an unresolved condition or a repair that was never certified.

No HPD lead-paint violations are on record for this building. That means no complaint or inspection was filed — not that the building is lead-free.
Built 1910. Under NYC Local Law 1 (Admin Code §27-2056.5), lead paint is presumed present in common areas and in apartments where a child under 6 resides, in multiple dwellings built before 1960. The presumption stands unless the owner obtained a lead-free or lead-safe exemption from HPD. Those exemption records aren’t published as open data, so we can’t confirm one either way.
