- City records show 79 open HPD violations, 36 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 2016 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 58 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 infestation consisting of roaches 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.
3728 Avenue K sits in Brooklyn, ZIP 11210. No subway stations are within an 800-meter walk — expect to rely on buses or rideshare.
Building Condition
Oldest open violation: May 2016 · Most recent: October 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.

23 open lead-paint hazard violations on record (most recent 2024). These are HPD violations recorded against the building — not a test of any specific apartment.
10 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 1926). 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: 12 procedural §27-2056 violations (failure to file required lead paperwork, most recent 2024) — a records failure, not evidence of a lead hazard.
