Common areas of a co-ownership (corridors, roof, facade, lift, garden) are managed collectively by the general assembly of co-owners. Modifications are decided by vote.

Types of modifications

The tenant has no say in the matter. Only the landlord votes at the assembly. See our general guide on co-ownership.

Tenant’s rights

The tenant can

  • Be informed of planned works and their duration
  • Request a rent reduction if loss of enjoyment
  • Report problems to the landlord (not directly to the building manager)
  • Use common areas in accordance with the regulations

The tenant cannot

  • Oppose works decided at the assembly
  • Modify common areas
  • Vote at the general assembly
  • Claim directly from the building manager

Informing the tenant

The landlord must inform the tenant of planned works in common areas. A reasonable notice period is 15 days for planned works.

In practice

For the landlord

  1. Attend general assemblies to defend the tenant’s interests
  2. Inform the tenant of decisions affecting their enjoyment
  3. Negotiate compensation if works are lengthy
  4. Notify the building manager if the tenant reports a problem

For the tenant

  1. Tolerate necessary works (legal obligation)
  2. Document the nuisances (photos, dates, duration)
  3. Report problems to the landlord in writing
  4. Request a rent reduction if the disturbance is significant

In case of dispute

If the landlord refuses any compensation despite significant disturbance:

  1. Formal notice by registered letter
  2. If no response, application to the justice of the peace
  3. The judge may order a retroactive rent reduction
