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 57 open HPD violations, 19 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 30 rent-stabilized units in this building — is this specific unit stabilized, and can the landlord show 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: Provide hot water at all hot water fixtures 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.

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 1900. 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.
