- City records show 22 open HPD violations, 7 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 2018 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 49 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: Replace or repair the self-closing doors that is missing or defective latch set at fire….
- 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.
535 East 21st Street sits in Brooklyn, ZIP 11226. The closest subway is Cortelyou Rd (Q) (6-minute walk), served by the Q line.
Building Condition
Oldest open violation: October 2018 · 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.

No HPD lead-paint violations on record. Built 1962. For buildings built between 1960 and 1978, Local Law 1 applies where the owner knows lead-based paint is present — there is no automatic pre-1960 presumption. Lead paint in residential use was federally banned in 1978.
