What 311 hears from this address

308 service requests in the last three years. Most common: Noise (160) · HEAT/HOT WATER (39) · UNSANITARY CONDITION (24) · PLUMBING (18) · DOOR/WINDOW (13) · WATER LEAK (10).

Filed construction activity

$44,500 in permitted construction work filed since 2016 (16 filings with a declared cost) — a rough measure of how actively the owner maintains the building. Permit costs cover filed construction work only — they do not capture routine maintenance or repairs done without a permit.

Rent-stabilization signals

1 of 3 signals present. Only a partial profile — stabilization is possible but less likely. The definitive answer for any unit: request its rent history from NYS Homes & Community Renewal (free, at hcr.ny.gov).
