Dividing a villa or creating a care dwelling: what differs?

The short answer

Creating two independent homes within one villa generally requires a Flemish environmental permit, even if no building work is needed. A smaller subordinate unit for qualifying care housing, known locally as « zorgwonen », may instead follow a notification procedure if every relevant condition is met. Housing a relative does not automatically meet those conditions, and a care unit does not automatically become a separately marketable home.

Define the intended use first

An independent apartment changes the number of dwellings. Flemish guidance requires a permit for that change even without physical work. The municipality assesses the actual plans, and structural building work may additionally require an architect. See also when a villa renovation needs an environmental permit.

Care housing serves a different purpose. The subordinate unit must be in or near an existing principally authorised home and accommodate the people or caregiver specified by the rules. The main home and the subordinate unit, or at least their bare ownership, must belong to the same owner or owners. Notification replaces the ordinary permit only when all other applicable conditions also hold.

Describe the position accurately on sale

Do not present an adapted wing or outbuilding as an independent apartment without evidence of its approved status. State what exists, which use has been permitted or notified, and which conditions still need checking. Include these records among the documents needed before selling. A clear file helps buyers understand the possibilities when selling a distinctive villa without treating a possible future division as an established right.
