What is the commercial use status of a property?
Commercial use status (commercialite) designates the right to use premises for commercial or professional purposes. In Paris, this concept is particularly important because the city applies strict regulations on changes of use, governed by articles L.631-7 and following of the French Construction and Housing Code.
In practical terms, a property is classified as either residential or commercial. Converting one to the other requires administrative authorisation and, in most cases in Paris, a compensation mechanism.
Why is commercial use status so important in Paris?
Paris is one of the municipalities that has implemented a prior authorisation requirement for changes of use. Since 2005, the City of Paris has imposed particularly stringent rules to protect the housing stock against commercial pressure.
The compensation principle requires the owner wishing to convert a dwelling into commercial premises to “restore” an equivalent residential area in the same arrondissement, or even the same neighbourhood for the most sought-after arrondissements (1st to 9th, and certain zones in the 10th to 18th). In practice, this compensation translates into the purchase of “commercial use certificates” from owners carrying out the reverse conversion, at prices that can reach 300 to 500 euros per square metre in central arrondissements in 2026.
The different scenarios
Already commercial premises: if the property has commercial use status, you can operate a business or professional activity there without any further steps. Check, however, that the co-ownership rules do not prohibit certain activities.
Residential premises to be converted: you must obtain a change-of-use authorisation from the City of Paris, with compensation. The procedure typically takes 3 to 6 months.
Mixed use: some premises benefit from mixed residential/professional use. This applies when the professional both practises and resides there simultaneously, subject to certain conditions.
Special case of liberal professions: practising a liberal profession in a dwelling is subject to specific rules, often more flexible than those for standard commercial activities.
How to verify a property’s commercial use status
Before any purchase, several checks are essential. The co-ownership descriptive statement of division specifies the designated use of each lot (residential, commercial, office). The co-ownership rules detail the activities that are authorised or prohibited. The City of Paris planning information sheet confirms the declared use of the premises. Finally, any current commercial lease specifies the activities being carried out.
Your property hunter carries out these checks systematically when analysing each property, even before the first viewing.
The impact on price
Premises with established commercial use status are worth significantly more than equivalent residential premises, precisely because this status has a market value in itself. In 2026 in Paris, the price difference can represent 15 to 30% depending on the arrondissement and location.
Conversely, a property sold with a doubtful or contestable commercial use clause can hold costly surprises after purchase.

FAQ
Is commercial use status permanent?
No. Commercial use status can be lost if the premises are used exclusively for residential purposes over a prolonged period. In Paris, a commercial premises converted to residential use without authorisation loses its commercial use status after a certain period.
Can you operate a business from an apartment in Paris?
It is possible but heavily regulated. You must obtain a change-of-use authorisation from the City of Paris, with the compensation mechanism. Certain liberal professions benefit from exceptions under specific conditions.
How much does a change of use cost in Paris in 2026?
The cost depends primarily on the compensation. In the central arrondissements, allow 300 to 500 euros per square metre for commercial use certificates. Add administrative and legal support fees, for a total budget of 20,000 to 80,000 euros depending on the area and location.
Is a change of use possible in every arrondissement?
Yes, but the conditions vary. The most sought-after arrondissements (1st to 9th) require compensation within the same arrondissement, sometimes even the same neighbourhood. Outer arrondissements offer more flexibility.
What does a property hunter check regarding commercial use status?
Your property hunter checks the descriptive statement of division, the co-ownership rules, the planning information sheet and the property’s usage history. They ensure the commercial use status is established, valid and compatible with your project.
