This briefing shows that the SRA model is a social innovation that can play an important role in tackling homelessness. It has demonstrated how the model developed as an innovative housing-led approach in Flanders over the 1980s and 1990s. The model was able to respond more effectively than existing services to the inadequately met housing needs of people facing homelessness and exclusion. Due to its success in allowing homeless people to exit homelessness and maintain a long-term reasonably secure tenancy, it has now become an established part of housing policy in Belgium. SRAs and similar models have been developed in a range of European contexts. This reflects growing interest in the role of the private rental sector in tackling homelessness.
