The Associação Cortiços do Centro, Condomínio Vanguarda (Association of Tenements in Central Areas – ACC) is a grassroots organisation comprised of residents of cortiços, or tenement-style slums in collective buildings in central areas of the city of Santos. The ACC seeks to improve the living conditions of low-income residents of five neighbourhoods in Santos city centre, working to ensure the right of low-income families to have access to decent housing whilst remaining in central areas, close to jobs and making use of existing urban infrastructure. This community-initiated project involves the construction of 181 housing units for low-income families. The first 113 units are at the finishing stages and the final 68 units are due to be completed by the end of 2013.
