What the co-ownership regulations say

In Belgium, the co-ownership regulations may govern the presence of pets in the building, but a total ban is generally deemed disproportionate by the courts.

Permitted clauses

ClauseValidity
Total ban on all animalsChallengeable in court
Leash required in common areasValid
Ban on dangerous animalsValid
Limit on number of animalsValid if reasonable
Ban in green spacesValid
Obligation to clean up droppingsValid

Prohibited clauses

The regulations cannot ban assistance animals (guide dogs, emotional support animals with medical certificate). This protection stems from the right to non-discrimination.

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

Tenant’s rights

When the lease allows pets

If the lease does not contain a prohibition clause, the tenant may keep a pet. The co-ownership regulations alone cannot override this right.

When the lease prohibits pets

The tenant must respect the prohibition clause they signed. In case of non-compliance, the landlord may:

  1. Send a formal notice to the tenant
  2. Request termination of the lease before the justice of the peace
  3. Claim damages

Exotic pets (NAC)

Reptiles, rodents and caged birds rarely cause issues in co-ownership, unless the regulations specifically mention them. Animals requiring a permit (exotic species) are governed by regional legislation.

Nuisances and remedies

Types of nuisances

NuisanceResponsible partyRemedy
Repeated barkingAnimal ownerBuilding manager, then justice of the peace
Odours (litter, cage)Animal ownerBuilding manager
Droppings in common areasAnimal ownerBuilding manager, infringement report
Damage to common areasUnit ownerLiability insurance
Stray animals in corridorsUnit ownerBuilding manager

Procedure in case of complaint

  1. The complainant reports to the building manager
  2. The building manager contacts the unit owner
  3. The owner intervenes with the tenant
  4. If the disturbance persists, formal notice
  5. As a last resort, application to the justice of the peace
Landlord's liability

The building manager addresses the unit owner, never the tenant directly. The landlord is responsible for ensuring the tenant complies with the co-ownership regulations.

Practical advice

For the landlord

  • Transmit the co-ownership regulations clauses on pets to the tenant
  • Include a pet clause in the lease (permission or prohibition)
  • Respond promptly to building manager complaints

For the tenant

  • Read the co-ownership regulations before signing the lease
  • Verify that your lease allows pets
  • Respect common areas and clean up droppings
  • Take out liability insurance covering your animal
