- City records show 99 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 2008 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 12 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.
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Abate the nuisance consisting of plexiglass at vestibule door at public hall.
- 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.
5409 Avenue O sits in Brooklyn, ZIP 11234. No subway stations are within an 800-meter walk — expect to rely on buses or rideshare.
Building Condition
Oldest open violation: September 2008 · Most recent: September 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.

4 open lead-paint hazard violations on record (most recent 2023). These are HPD violations recorded against the building — not a test of any specific apartment.
21 earlier hazards cited and remediated.
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.
Also on record: 1 procedural §27-2056 violation (failure to file required lead paperwork, most recent 2025) — a records failure, not evidence of a lead hazard.
