10 Union Square East was built in 1988 — roughly 38 years old. This is a condominium of 696 units — each unit is its own tax lot with its own bill. Search with a unit number for unit-level figures. 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 building already exceeds what current residential zoning would allow (13.83 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. Those figures are for residential use — the lot also carries a commercial allowance of 10.00 FAR.
