- City records show 43 open HPD violations, 22 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 2019 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 20 rent-stabilized units here. Ask whether this specific unit is one of them, and ask the landlord for its legal regulated rent and lease history.
- 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: Abate the infestation consisting of roaches in the entire apartment.
- 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: March 2019 · Most recent: August 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.

18 lead-paint hazards cited and later remediated (most recent 2022); no open hazards on record. Remediation addresses the cited conditions, not necessarily every painted surface.
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 (this building: built 1918). 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.
