520 Fifth Avenue was built in 2024 — roughly 2 years old. 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 zoning would allow (31.44 built FAR vs. a maximum of 15.00) — typically a grandfathered or overbuilt structure that could not be rebuilt to this size under today’s rules.
