- City records show 49 open HPD violations, 4 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 2000 — why has it stayed open this long, and is it in or near this unit?
- We found no DHCR rent-stabilization unit count for this building. That is not the same as the building being market-rate — a registration can be on file with no unit figure, or not have been filed at all. Ask the landlord directly whether the unit is rent-stabilized, and request your own rent history from DHCR.
- 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: September 2000 · 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 1872. 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.
