305 East 88 Street was built in 1929 — roughly 97 years old. This is a co-op building with 90 apartments — residents own shares in the corporation that owns the building, rather than their apartments outright. Apartments average about 821 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 $770,928 per year — passed to residents through monthly maintenance in proportion to each apartment’s share allocation. A straight average works out to roughly $8,566 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 5C, for $775,000 in Jul 2026.
The building is built out to essentially the full residential density its zoning allows (4.19 of 4.00 FAR), so there is little room to expand under current rules. This lot is associated with a co-op; individual apartments are owned as shares and taxed through the building.
