Filed construction activity

$84,500 in permitted construction work filed since 2016 (8 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).

What the city thinks it's worth

The city's market estimate has fallen 11% between tax years 2025 and 2027.

For property tax, the Department of Finance values this co-op as if it were a rental building. Its 2022 estimate: gross income $864,945 a year ($19.35 per sq ft), operating expenses $426,438 ($9.54 per sq ft), net operating income $438,507. These are the city's estimates from comparable rentals, not the building's actual budget, rents or maintenance charges.
