Patterns

What 311 hears from this address

32 service requests in the last three years. Most common: PLUMBING (9) · HEAT/HOT WATER (8) · PAINT/PLASTER (7) · Missed Collection (2) · Drinking (1) · Damaged Tree (1).

Filed construction activity

$876,120 in permitted construction work filed since 2016 (9 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. This is the classic profile of a rent-stabilized building (pre-1974, 6+ units) — many units in such buildings remain stabilized. The definitive answer for any unit: request its rent history from NYS Homes & Community Renewal (free, at hcr.ny.gov).
