- City records show 9 open HPD violations, 1 immediately hazardous (Class C) under 709 Hart Street — 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 2019 — why has it stayed open this long, and is it in or near this unit?
- Confirm the condition behind the most recent open violation was actually repaired, not just marked closed: Post notice, in form approved by the department, stating the name and location….
- 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.
721 Hart Street sits in Brooklyn, ZIP 11221. The closest subway is Central Av (M) (3-minute walk), served by the J, L, and M lines.
Building Condition
Issued February 2019. 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.
