History

In 1947, the residents of Potomac Heights formed a co-operative and purchased the entire community from the previous owners (the US government). It was built in 1940–1943 to provide housing for defense workers. Today, to obtain the right to occupy one of the co-op residences, one must first apply for and be accepted for membership in the co-operative. To gain acceptance one must meet the criteria established by voting members of the co-op.

Potomac Heights is one of many housing co-operatives in the Washington, D.C. metropolitan area, three of which were converted from government sponsored housing. The largest co-operative, Greenbelt, located in adjoining Prince George's County, evolved from one of three planned communities (Greendale, Wisconsin, and Greenhills, Ohio) and developed as a federally supervised experiment in cooperative living under the New Deal during the Roosevelt administration. Hillwood Square Mutual in Falls Church, Virginia, was built to house workers at the Torpedo Factory in Alexandria.
