About this building
48 apartments — the most of any of the 13 buildings we cover on this block, and more than 90% of the 881 residential buildings we cover in ZIP 11206 have fewer. The building’s floor space is 3.9 times the size of its lot: 35,200 sq ft of building on a 9,000 sq ft lot.
Comparisons with neighboring buildings, as of October 31, 2026.
A difference between the DHCR rent-stabilized count and the PLUTO total is common and does not, on its own, indicate a violation: units can leave rent stabilization legally, the two datasets count units differently, some units may be non-residential, and a registration can be filed incompletely. To check your own apartment, see how to request your rent history from DHCR.

- City records show 48 open HPD violations, 11 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 2021 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 36 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: Properly repair or replace the broken or defective entrance door.
- 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.

Building Condition
Oldest open violation: June 2021 · 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.

1 open lead-paint hazard violation on record (most recent 2022). These are HPD violations recorded against the building — not a test of any specific apartment.
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 1931). 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.
