Frequently Asked Questions

Key Answers: Trades & Renovation

Q:How do I verify a tradesperson or artisan in France before hiring them?

Always verify their active legal registration via their 14-digit SIRET number on official French business databases (such as INPI or Infogreffe). Check that their registered business activity code (Code APE/NAF) corresponds directly to the work being performed, and ensure their civil liability and 10-year insurance (Garantie Décennale) is active.

Q:What is Garantie Décennale and who must provide it?

Under Article 1792 of the French Civil Code, Garantie Décennale is mandatory 10-year defect liability insurance covering structural works, foundations, load-bearing walls, roofs, and waterproofing. Every builder, roofer, mason, and contractor executing structural or integral works must provide a valid décennale certificate before opening the site.

Q:Is a signed French Devis a legally binding contract?

Yes. Once a devis (quote) is accepted with the handwritten words "Bon pour accord", signed and dated by both parties, it becomes a legally binding contract under French consumer and commercial law. Any changes in cost or scope require a formal written avenant (amendment).
