- City records show 5 open HPD violations 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 2026 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 39 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: Properly repair or replace the broken or defective mortis lock at vestibule door.
831 Madison Street sits in Brooklyn, ZIP 11221. The closest subway is Gates Av (J,Z) (2-minute walk), served by the J and Z lines.
Building Condition
Issued 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.

14 lead-paint hazards cited and later remediated (most recent 2023); 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 1925). 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 2023) — a records failure, not evidence of a lead hazard.
