In Belgian co-ownership, cellars and attics may be either private areas or common areas. This distinction is fundamental to the tenant’s rights.

Private area vs common area

StatusDefinitionConsequence for the tenant
Private areaAttached to a unit (mentioned in the deed of division)Included in the rental if provided for in the lease
Common areaBelongs to all co-ownersUse according to co-ownership regulations
Common area with exclusive useAssigned to a unit but remains commonAccording to the lease and regulations

Verifying the status

The status of cellars and attics is defined in the deed of division of the co-ownership. The landlord must check this document before mentioning a cellar or attic in the lease.

For the general framework, see our guide on co-ownership and renting.

Co-ownership regulations

The co-ownership regulations may provide additional rules: access hours, padlock requirement, prohibition on modifying partitions.

Cellar inventory of fixtures

Remember to include the cellar and attic in the inventory of fixtures at move-in and move-out. Photograph the condition of the walls, floor and installations (electricity, lighting).

Recoverable charges from the tenant

Cleaning and lighting costs for common areas (cellar access corridors) are recoverable charges. Current maintenance of the private cellar (cleaning, tidying) is the tenant’s responsibility.

Practical advice

For the landlord

  1. Check the status of the cellar/attic in the deed of division
  2. Clearly mention the cellar in the lease and its floor area
  3. Include the cellar in the inventory of fixtures
  4. Transmit the rules of use to the tenant

For the tenant

  • Confirm cellar access before signing
  • Photograph the condition of the cellar at move-in
  • Comply with the storage rules in the regulations
  • Report any water ingress or damp to the landlord

For parking in co-ownership, similar rules apply. Manage your documents with a rental management software.
