911 7 Avenue was built in 1909 — roughly 117 years old. This is a co-op building with 75 apartments — residents own shares in the corporation that owns the building, rather than their apartments outright. Apartments average about 1,610 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 $1,424,285 per year — passed to residents through monthly maintenance in proportion to each apartment’s share allocation. A straight average works out to roughly $18,990 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 11A, for $1,800,000 in Jun 2026.
City landmark records describe it as a French Renaissance apartment building dating to 1907 - 1909, originally used as residential, multi-family. It was designed by Harde & Short. The building is a designated New York City Individual Landmark.
The building is built out to essentially the full residential density its zoning allows (9.64 of 10.00 FAR), so there is little room to expand under current rules. Those figures are for residential use — the lot also carries a commercial allowance of 4.00 FAR. This lot is associated with a co-op; individual apartments are owned as shares and taxed through the building.
