45 Sutton Place South was built in 1958 — roughly 68 years old. This is a co-op building with 278 apartments — residents own shares in the corporation that owns the building, rather than their apartments outright. Apartments average about 1,837 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 $7,532,797 per year — passed to residents through monthly maintenance in proportion to each apartment’s share allocation. A straight average works out to roughly $27,096 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 21-I, for $2,140,000 in Aug 2026.
The building already exceeds what current residential zoning would allow (16.76 built FAR vs. a residential maximum of 10.00) — typically a grandfathered or overbuilt structure that could not be rebuilt to this size under today’s rules. This lot is associated with a co-op; individual apartments are owned as shares and taxed through the building.
