Filed construction activity

$103,000 in permitted construction work filed since 2016 (4 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

0 of 3 signals present. None of the common signals are present — stabilization is unlikely (though never impossible). The definitive answer for any unit: request its rent history from NYS Homes & Community Renewal (free, at hcr.ny.gov).
