Habitat For Humanity International (HFHI) (generally referre to as Habitat for Humanity or simply Habitat) is an international, ecumenical Christian, non-governmental, non-profit organization devoted to building "simple, decent, and affordable" housing. Homes are built using volunteer labor and are sold at no profit. In many countries outside the United States, Habitat for Humanity charges interest to protect the Revolving Fund from inflation. The organization was founded in 1976 in Americus, Georgia by Millard and Linda Fuller, whose vision grew out of their experiences at Koinonia Farm. The international headquarters located in Atlanta (moved from Americus GA in 2006) serves to support and promote the activities of local, independent affiliate chapters, which initiate and manage all construction, mortages, and homeowner selection.
