- City records show 7 open HPD violations, 3 immediately hazardous (Class C) under 340 Mc Guinness Boulevard — 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 2023 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 6 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: Mdl and 28 rcny §25-171: replace or repair the self-closing the doors that is missing or….
- 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.
340 Mcguinness Boulevard sits in Brooklyn, ZIP 11222. The closest subway is Greenpoint Av (G) (5-minute walk), served by the G line.
Building Condition
Oldest open violation: May 2023 · Most recent: May 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.

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 1930. 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.
