tonttijakoja
Tonttijakoja, or lot division, is a procedure in Finnish land management that divides a larger property, a tontti, into smaller, separate units called tonttiosat. This process is primarily used for creating new building plots or when an existing property is divided for the purpose of separate ownership or use. The division is based on a detailed plan, a tonttijakosuunnitelma, which is prepared by a licensed land surveyor. This plan specifies the boundaries, areas, and intended uses of the new tonttiosat.
The purpose of tonttijakoja is to facilitate the efficient use of land, particularly in urban areas where
