Can the allocation of a co-ownership lot be changed?

Verified 26 July 2022 - Directorate for Legal and Administrative Information (Prime Minister)

Yes, you can change the assignment of private parts of your co-ownership lot (for example, you can turn your apartment into a doctor's office). For that to happen, this change must respect the destination of the building fixed by the co-ownership rules and the rights of other co-owners. For example, this change must not cause any noise or odor nuisance to other co-owners.

FYI  

Where the co-ownership regulation prohibits the exercise of a professional activity, it is possible to request the change of the co-ownership regulation at a general meeting.

A change in the use of the private parties shall entail a change in the condominium tenants.

Warning  

if you live in 92, 93 or 94 or in a city of more than 200,000 inhabitants, you must also obtain authorization from the city council to change the allocation of your lot. A decision by the municipal council shall lay down the conditions for the issue of such authorization. To know these conditions, you must contact the city council (or consult the municipal by-law sometimes available on its website).
