No current HPD flags in the latest weekly snapshot: no open violations, no pending litigation, no active vacate orders, and not in the Alternative Enforcement Program.
12 heat or hot-water complaints in the last three years (winter 2024–25: 2 · winter 2025–26: 6). Repeated winter clusters suggest a chronic heating problem.
No bedbug-infested units reported in the last three years of filings.
$12,500 in enforcement penalties imposed (ECB/OATH) in the last three years.
22 service requests in the last three years. Most common: HEAT/HOT WATER (6) · DOOR/WINDOW (5) · PAINT/PLASTER (3) · PLUMBING (2) · APPLIANCE (2) · Sidewalk Condition (1).
$2,693,730 in permitted construction work filed since 2016 (13 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.
