321 East 89 Street was built in 1950 — roughly 76 years old. This is a co-op building with 34 apartments — residents own shares in the corporation that owns the building, rather than their apartments outright. Apartments average about 522 sq ft (building area divided by apartment count — individual units vary). For property-tax purposes it falls under Class 2 (residential buildings with four or more units, condos and co-ops), taxed at 12.439% of a taxable value based on 45% of the city’s income-derived market value. The corporation pays one building-wide tax bill — about $258,895 per year — passed to residents through monthly maintenance in proportion to each apartment’s share allocation. A straight average works out to roughly $7,615 per apartment per year, though larger apartments carry more shares (and many primary residents get the co-op/condo abatement on top). The most recent recorded sale in the building was unit 1G, for $460,000 in Jun 2026.
The building uses about 88% of the residential density its zoning allows (3.52 built FAR vs. a residential maximum of 4.00) — roughly 2,416 sq ft of unused development rights, which can matter for renovations, expansions, or air-rights value. This lot is associated with a co-op; individual apartments are owned as shares and taxed through the building.
