- City records show 8 open HPD violations, 1 immediately hazardous (Class C) under 738 St Marks Avenue — the address HPD files this building’s records under, not the address on this page. Ask which are still unresolved in the unit and the landlord’s timeline to clear them.
- The oldest open violation on record dates to 2025 — why has it stayed open this long, and is it in or near this unit?
- We found no DHCR rent-stabilization unit count for this building. That is not the same as the building being market-rate — a registration can be on file with no unit figure, or not have been filed at all. Ask the landlord directly whether the unit is rent-stabilized, and request your own rent history from DHCR.
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Remove the illegal fastening padlock at exit gate to iron fence, at west wall,northwest….
- 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.
738 Saint Mark's Avenue sits in Brooklyn, ZIP 11216. The closest subway is Nostrand Av (3) (7-minute walk), served by the 2, 3, 5, A, C, and S lines.
Building Condition
Oldest open violation: May 2025 · Most recent: 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.

5 lead-paint hazards cited and later remediated (most recent 2025); 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 1900). 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.
