Where the penalty points come from

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.

Patterns

6 heat or hot-water complaints in the last three years (winter 2024–25: 6).

3 bedbug-infested unit(s) reported in filings over the last three years.

What 311 hears from this address

8 service requests in the last three years. Most common: Lead (3) · HEAT/HOT WATER (3) · PLUMBING (1) · Consumer Complaint (1).

Filed construction activity

$25,220 in permitted construction work filed since 2016 (2 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).
