A statutory trust set up for a particular area with the objects to secure: the repair and improvement of housing in the area; its proper and effective management; greater diversity of kinds of tenure of the housing; and the improvement of social and living conditions in the area generally. In their areas, housing action trusts can be given power to exercise most of the functions of a housing authority and the planning control and public-health functions of local authorities. Local authority housing can be transferred to a housing action trust by government order if a majority of the tenants agree. A housing action trust must achieve its objects as quickly as possible and is then dissolved and its property disposed of. Housing action trusts were introduced by the Housing Act 1988.
