The purpose of the master plan is to provide general guidance on the community structure and land use of a municipality or part of it and to coordinate operations. The master plan sets out the principles of the desired development and indicates the necessary areas for detailed city planning and other planning as well as for construction and other land use. The master plan for the whole municipality forms the basis for the urgency of planning work. The planning programme is checked annually in conjunction with the planning review. The master plan can also be drawn up in stages or by city sub-district as a so-called component master plan, which guides land use and construction in a given area. The master plan may be determined to be binding or indicative. The municipality is responsible for the preparation of the master plan. The plan is approved by the municipal council.
