51 East 78 Street was built in 1894 — roughly 132 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. At the current assessment that works out to about $240,874 per year ($20,073/month) before any abatements or exemptions the owner may receive. City records show it last changed hands for $440,000 in Jun 2026.
City landmark records describe it as a Vernacular neo-Georgian tenement dating to 1893 - 1894, originally used as residential, multi-family. It was designed by Thom & Wilson for Thomas McLaughlin. It stands within the Upper East Side Historic District.
The building is built out to essentially the full density its zoning allows (3.81 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.
