As the regulatory body of the community housing sector, South Australian Community Housing Authority (SACHA) acts to ensure that community housing organisations perform their functions in accordance with the South Australian Co-operative and Community Housing Act 1991 . As the funder of the sector, SACHA provides capital funding and other supports to assist the growth of community housing organisations.

SACHA does not provide housing directly to the public nor does it manage tenancies - these functions are provided by community housing organisations throughout South Australia. SACHA does, however, assist community housing organisations to access housing stock through a capital program that is linked to broader government social housing asset management policies, and urban renewal and development policies.
