The planning hierarchy progresses from national land use objectives to regional plans, then to master plans and finally to local detailed plans.


Land use planning is based on a system of plans that becomes more detailed as it progresses from general to specific. This is known as a hierarchical planning system. The principle of the system is that a broader and more general plan or other plan guides more detailed planning. In addition, the planning hierarchy means that when a more detailed plan has been completed and approved, it replaces the higher-level plan.

The most general level consists of national land use objectives (valtakunnalliset alueidenkäyttötavoitteet) and regional land use plans (maakuntakaava). National land use objectives outline the use of areas in matters of national significance and are decided by the Government. A regional plan is a general plan for land use in a region or part of a region. It sets out the principles for land use and community structure and identifies areas that are necessary for the development of the region.

The regional plan is specified in more detail in the master plan (yleiskaava). The purpose of the master plan is to provide general guidance on the community structure and land use of a municipality or part thereof and to coordinate activities.

Local detailed plans (asemakaava) are the most detailed, precise and binding types of plans.

The name of the Land Use and Building Act (maankäyttö- ja rakennuslaki), which regulates zoning, has been changed to the Land Use Act (alueidenkäyttölaiki).

Different levels of the planning hierarchy: regional plan, master plan and local detailed plan. At the bottom is the regional plan, which guides land use in a large area and defines the main lines of the areas, such as transport networks and regional land reservations. Above it is the master plan, which specifies the principles of land use at the municipal level. At the top is the local detailed plan, the most detailed level in the planning hierarchy, which defines the precise boundaries of construction and land use at the block and plot level.
