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 48 open HPD violations, 16 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 2017 — why has it stayed open this long, and is it in or near this unit?
- Public records list 69 rent-stabilized units in this building — is this specific unit stabilized, and can the landlord show its legal regulated rent and lease history?
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Abate the nuisance consisting of ac unit protruding more than 4 inches at balcony, 2nd….
- 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.

22 lead-paint hazards cited and later remediated (most recent 2026); 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 1928). 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.
