MGP will take the responsibilities in the field of: management of resources to support social housing, renovation of housing, elimination of low-quality buildings. The implementation of the housing policy at the metropolitan level is associated with a number of challenges mainly in terms of consolidation of activities undertaken by the institutions of social housing, reservation of land for social housing investments, increase in the amount of new housing, including attempts for their more even distribution at the metropolitan scale.
