About this building
City records list 1926 as the year built — newer than 82% of the 1,388 buildings we cover in ZIP 10027. The building’s floor space is 4.3 times the size of its lot: 28,668 sq ft of building on a 6,728 sq ft lot.
Comparisons with neighboring buildings, as of November 7, 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 45 open HPD violations, 4 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 1999 — why has it stayed open this long, and is it in or near this unit?
- DHCR’s most recent registration lists 30 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: Repair the broken or defective plastered surfaces and paint in a uniform color at east….
- 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: October 1999 · 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.

2 open lead-paint hazard violations on record (most recent 2015). 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 1926). 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.
