555 Kappock Street was built in 1966 — roughly 60 years old. This is a co-op building with 412 apartments — residents own shares in the corporation that owns the building, rather than their apartments outright. Apartments average about 1,308 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 $1,866,906 per year — passed to residents through monthly maintenance in proportion to each apartment’s share allocation. A straight average works out to roughly $4,531 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 21E, for $590,000 in Jul 2026.
The building already exceeds what current residential zoning would allow (5.93 built FAR vs. a residential maximum of 2.43) — typically a grandfathered or overbuilt structure that could not be rebuilt to this size under today’s rules. Those figures are for residential use — a community-facility use (a doctor’s office, clinic, or school) raises the ceiling to 4.80 FAR. This lot is associated with a co-op; individual apartments are owned as shares and taxed through the building.
