Where the penalty points come from

Open with the city right now

Patterns

4 heat or hot-water complaints in the last three years (winter 2024–25: 2 · winter 2025–26: 2). Repeated winter clusters suggest a chronic heating problem.

No bedbug-infested units reported in the last three years of filings.

$10,030 in enforcement penalties imposed (ECB/OATH) in the last three years.

What 311 hears from this address

332 service requests in the last three years. Most common: Illegal Parking (187) · Vendor Enforcement (33) · Noise (24) · PLUMBING (11) · Dirty Condition (7) · Street Condition (7).

Filed construction activity

$32,582,850 in permitted construction work filed since 2016 (39 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

2 of 3 signals present. Buildings receiving 421-a or J-51 benefits are generally required to register their units as rent-stabilized for the duration of the benefit. The definitive answer for any unit: request its rent history from NYS Homes & Community Renewal (free, at hcr.ny.gov).
