Social housing has a specific function in the housing stock. It is primarily an instrument used in the system of social assistance, implemented by public authorities. One of the main problems that arise during making decisions about provision of social housing is the problem of localization. Local authorities must answer the question whether it is better to change the destination of the existing housing stock and create social housing within the city, and also derive social housing in areas outside the city and create social districts? How to balance the social development in the area of the city, to manage it according to the theory of sustainable development? The purpose of this paper is to assess the impact of the activities carried out by local authorities in Poland regarding the provision of social housing in the context of sustainable management of the city.
