alalohko

Alalohko is a cadastral term used in some Nordic land registration systems to designate a sub-block within a larger parcel. It appears in planning documents and property descriptions as a smaller, legally recognized portion of a block, which may be delineated for specific uses while remaining part of a larger property.

Etymology: From Finnish ala- “sub-” or “lower” and lohko “block” or “section”; the compound conveys a secondary subdivision of a block.

Usage and legal status: An alalohko is typically described in cadastral plans to allocate space for distinct functions, such as an independent entrance, parking area, or service yard within a building block. Ownership may still lie in the main parcel or be divided among owners through separate deeds; in some jurisdictions, an alalohko may carry ownership or use rights registered separately, affecting maintenance and taxation.

Regional context and variation: The exact standing of an alalohko varies by registry, and the term is more common in some Finnish and Swedish-language documentation than in others. It is analogous to concepts known as sub-blocks or subdivisions in other legal systems, with different terminology and formal requirements.
