4. NYC’s Largest Apartment Complex

With its 15,372 apartments, Co-op City is the largest apartment complex in New York.

By comparison, the number of units in other notable but smaller complexes include 12,271 at Parkchester, also in The Bronx; 11,250 at Stuyvesant Town-Peter Cooper Village; 5,860 at Rochdale Village in Queens, which was developed by the same team as Co-op City; 4,605 at LeFrak City; and 3,142 at the Queensbridge Houses, the city’s largest public housing development.

Co-op City is also believed to be the largest apartment complex in the US, though no authoritative source seems to keep records on the subject. Outside the US, however, Co-op is small potatoes compared to developments like Marzahn, a 59,646-unit complex built by the East German government in Berlin.
