Building Permits & Planning Permission in France

In France most building work needs either a building permit (permis de construire) or a lighter prior declaration (déclaration préalable de travaux), filed with the town hall and judged against the local plan. English-speaking lawyers in France check what a project needs, deal with refusals and neighbours' challenges, and help regularise works done without permission.

About Building Permits & Planning Permission in France

A building permit or planning permission in France is, for larger works, a permis de construire, and for smaller ones a déclaration préalable de travaux. People also search for “planning application France”, “retrospective planning permission France” or “swimming pool planning permission France”. Both are filed with the town hall (mairie) and decided under the commune's local plan (PLU). Some older lists and lawyer pages call this service “Urban Planning Law”. English-speaking lawyers in France help owners and buyers of houses, plots and holiday homes.

Who needs it

  • Owners planning an extension, a swimming pool, a garage, new windows, a change of facade or the conversion of a barn.
  • Buyers who want to know whether a house and its outbuildings were built with the right authorisations.
  • Owners who discover, often at a sale, that earlier works were never declared.
  • Neighbours affected by a permit granted next door.

How it works in France

Which authorisation applies depends on the size of the works, the zone and the type of building. An urban planning certificate (certificat d'urbanisme) tells you in advance which rules govern a plot, and some projects require an architect. Near listed monuments the Architecte des Bâtiments de France has a say. A granted permit is displayed on site, neighbours can challenge it within a limited period, and at the end of the works the owner files a declaration that they are finished and conform to the permit (DAACT).

Works done without permission

Unauthorised works can often be regularised by filing a permit or a declaration after the fact, but the application is judged under the rules in force when it is filed, not when the works were done. A building put up with no permit at all is not protected by the passage of time in the way minor irregularities can be, and administrative regularisation does not wipe out criminal liability; in serious cases a court can order demolition. Each case turns on its own facts.

What a lawyer does

Reads the local plan and the history of the property, prepares or reviews the application with your architect, answers requests from the town hall, challenges a refusal or defends a permit against neighbours, and works on regularisation before a property sale or a property purchase. Disputes with neighbours over boundaries or rights of way are covered under property rights and disputes.

Questions and answers

Do I need planning permission for a swimming pool in France?

Many pools need at least a prior declaration, and larger or covered ones a building permit; the size, the cover and the zone decide.

What is the difference between a permis de construire and a déclaration préalable?

The declaration is the lighter procedure for small works and changes of appearance; the permit covers new buildings and larger extensions.

Can a house with unauthorised works be sold?

It can, but the buyer, the notary and any lender will ask questions, and the risk passes to the buyer; regularising first is often the cleaner route.

Can the property be let to holidaymakers once the works are done?

Short-term letting has its own registration rules in many communes, and they have changed more than once; see tourist rental licence and registration.

  • The lawyer assisted and advised me on a possible medical negligence claim. I did not pursue it in the end, but my case was examined in depth and I was supported throughout in a professional, sympathetic way. I was told that the claim would probably fail and that I should not spend more money that might well be wasted. The fee was very reasonable given the situation. I would thoroughly recommend this service, and her above all.
