Filed construction activity

$2,026,380 in permitted construction work filed since 2016 (21 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).
