The National Association of Housing Cooperatives (www.nahc.coop) is a nonprofit national federation of housing cooperatives, mutual housing associations, member associations, other commonly owned resident-owned or controlled housing, professionals, organizations, and individuals interested in promoting the interests of cooperative housing communities. Organized in 1950 and incorporated in 1960, NAHC is the only national cooperative housing organization. Membership in NAHC provides many benefits. It is a forceful advocate in Washington, D.C., for cooperative housing and cooperative housing legislation and provides many member services, including a national conference with outstanding educational programs and an annual meeting at which member cooperatives elect members to the board of directors.
