Allocation of works costs

In Belgian co-ownership, the allocation of works costs follows a clear logic: works in common areas are borne by the co-owners; tenant repairs in private areas are borne by the tenant.

Common areas (landlord)

WorksBorne by
Roof (repair, renovation)Co-owners (shares)
Facade (rendering, insulation)Co-owners
Lift (replacement, modernisation)Co-owners
Common pipesCo-owners
Entrance hall, stairsCo-owners
Parking (slab, waterproofing)Co-owners

Private areas (landlord/tenant split)

Boiler replacementYesNo
Annual boiler servicingNoYes
Window replacementYesNo
Lock repairNoYes
Repainting (normal wear)YesNo
Holes in walls (not wear)NoYes

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

Decision and vote on works

Majorities required at the general assembly

Type of worksMajority required
Current common area maintenanceAbsolute majority (50% + 1)
Improvement worksQualified majority (2/3)
Works affecting sharesQualified majority (4/5)
Demolition/reconstructionQualified majority (4/5)
Urgent worksBuilding manager decision (without GA)

Funding

Works may be financed by:

  • The reserve fund (planned major repairs)
  • An exceptional special levy (unforeseen works)
  • A collective loan (major projects)
Urgent works

The building manager may order urgent works without waiting for the general assembly (water leak, safety risk). The building manager must inform the co-owners and ratify the decision at the next GA.

Impact on the tenant

Obligation to tolerate works

The tenant must tolerate works in common areas, even if they cause temporary disturbance. The tenant cannot oppose them if the decision was voted at the general assembly.

Rent reduction

If works cause a significant disturbance of enjoyment:

DisturbanceTenant’s remedy
Excessive noise for several weeksNegotiated rent reduction
Restricted access to the propertyRent reduction or temporary rehousing
Scaffolding blocking lightTemporary rent reduction
Extended water/electricity cutRent reduction, potentially damages

Informing the tenant

The landlord must inform the tenant of planned works: nature, estimated duration, impact on enjoyment. This information must be given within a reasonable time before the works begin.

Practical advice

For the landlord

  1. Attend GAs to anticipate the works voted
  2. Inform the tenant of planned works and their duration
  3. Negotiate a temporary rent reduction if the disturbance is significant
  4. Do not recharge common area works in the charges

For the tenant

  • Document the disturbances (photos, nuisance log)
  • Request written compensation in case of significant disturbance
  • Report problems to the landlord in writing (not directly to the building manager)
  • Keep evidence for any potential claim

Formalise your rights and obligations in the lease. Track works and communications with a rental management software.
