In the spring of 1969, the Association of Owners of Family Residential Houses and Condominiums of the Socialist Republic of Slovenia was established; its members were owners of “occupied dwellings” (residential houses and condominiums). These dwellings became occupied in the first years after the war, when help was needed with solving the housing crisis which was a consequence of the housing fund's collapse and the mass migration from the countryside to the cities due to industrialisation. After nearly a quarter of the century, their houses and dwellings were still occupied by tenants and could therefore not be used. Therefore, they tried to change the Housing Act through the work of the association as the Act was limiting their right to ownership. Based on the archival materials of the Association of Owners of Family Residential Houses and Condominiums, the problems that owners of “occupied dwellings” faced are presented.
