Paiking policy is run by each municipality. The State Commission for Urban Development and Housing involves the Ministries of Urban Development, Government, Environment, Water and Works, and Communications. These ministries can ask for opinions from other relevant authorities for evaluating different components of the urban impact assessment (e.g. mobility-related authorities for impacts on road access and vehicle traffic flows) but they are not obliged to do so, or to take this opinion into account in their final decision on granting the construction permit.
