About this building
City records list 2024 as the year built — newer than 99% of the 1,017 buildings we cover in ZIP 11216, and the newest of the 7 buildings we cover on this block. At 7 floors, the tallest on this block. 37 apartments — the most of any building we cover on this block, and more than 94% of the 1,010 residential buildings we cover in ZIP 11216 have fewer. The building’s floor space is 3.6 times the size of its lot: 36,188 sq ft of building on a 9,979 sq ft lot.
Comparisons with neighboring buildings, as of October 28, 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 7 open HPD violations, 2 immediately hazardous (Class C) under HPD building ID 999658. Ask which are still unresolved in the unit and the landlord’s timeline to clear them.
- The oldest open violation on record dates to 2026 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 8 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: Provide hot water at all hot water fixtures 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.
