The Free State of Bavaria promotes the construction and modernization of rental apartments for those eligible for social housing assistance. The selection of new construction projects to be subsidized is based on the urgency of local housing needs. In return for the subsidies, the subsidized apartments are subject to housing restrictions, which can restrict both the authorized users (owners) and tenants in the use of the properties. The most important restrictions here are the occupancy and rent restrictions.

The district authorities, independent cities, large district towns or "large delegation municipalities" are responsible for enforcing housing restrictions. They ensure the intended use of subsidized housing in their area (including subsidized owner-occupied housing that is to be rented out during the commitment period). This includes the occupancy of the apartment by authorized tenants, compliance with the permissible rent level and, for example, issues relating to the expiry of the commitment and the conversion of social rental apartments into owner-occupied apartments. They prosecute violations of the housing commitment and, if necessary, evict tenants.
