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 space is often limited. It allows for the creation of individual plots suitable for single-family homes, apartment buildings, or commercial properties. Once the tonttijakosuunnitelma is approved by the relevant municipal authority and registered in the official land register, the tonttiosat become legally recognized and can be sold, inherited, or mortgaged independently. This process is crucial for urban development and property transactions in Finland. It ensures that land is divided in a way that is practical for building and ownership, adhering to zoning regulations and urban planning principles.
