- City records show 270 open HPD violations, 13 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 1984 — why has it stayed open this long, and is it in or near this unit?
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Repair the broken or defective plastered surfaces and paint in a uniform color ceiling….
- 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.

1 open lead-paint hazard violation on record (most recent 2011). These are HPD violations recorded against the building — not a test of any specific apartment.
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 1920). 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.
