Understanding the insurance around a building project
Decennial insurance, dommages-ouvrage (building defects insurance), professional liability and building liability do not cover the same situations. Decennial liability insurance protects professionals whose liability can be engaged for ten years after handover, while dommages-ouvrage insurance is taken out by the project owner to pre-fund the repair of certain defects before liability is established.
The Spinetta Act of 1978 organises French construction insurance around this link between builders’ liability and the project owner’s insurance. Depending on your role and the type of works, your insurance obligations, the covers to plan and the documents to provide differ. A prior review avoids confusing contracts with different legal purposes.
Professional liability insurance works in another area: it covers damage caused to third parties in the course of your business that does not necessarily fall under the decennial guarantee. For a company with premises, a depot or equipment, industrial multi-risk insurance can complete the set-up to protect its assets and tools.
The insurance certificate lets you check the covers in force, their period of validity and the declared activities: works carried out outside declared activities may not be covered. For an owner or a co-ownership, building liability for owners and managing agents addresses specific property risks (see also our property insurance page). The aim is to coordinate covers rather than look for a single contract that supposedly covers everything.

Frequently asked questions
What is the difference between decennial insurance and dommages-ouvrage?
The decennial guarantee relates to the builder’s liability. Dommages-ouvrage is taken out by the project owner to be compensated quickly for certain defects, without waiting for liability to be established.
Does professional liability replace decennial insurance?
No. Professional liability and decennial liability cover different risks. A construction professional generally needs both, depending on their activity.
What does the 1978 Spinetta Act provide?
The Spinetta Act of 4 January 1978 organised construction insurance in France around the decennial liability of builders and dommages-ouvrage insurance.
What is a decennial insurance certificate for?
It lets you check the declared activities, the validity period and the covers in force of the professional. The project owner can ask for it before works start.
Does a building owner have the same needs as a construction company?
No. A building owner, a construction company and a project owner do not bear the same liabilities. The contracts to review depend on their role.
