Responsabilité décennale, definition and guide for maîtres d'œuvre

Responsabilité décennale (decennial liability) is the strict 10-year liability of builders, including the architect and the maître d'œuvre, running from the réception of the works. It covers damage that compromises the solidity of the structure or makes the work unfit for its intended purpose. It is set by the loi Spinetta of 4 January 1978 and codified in article 1792 of the French Code civil.

What decennial liability means in practice

The 10-year period starts at réception, the date recorded in the PV de réception (handover record). Any decennial-grade defect found before that point engages the builder, including reserves cleared late. Proof of the building's condition at réception therefore becomes the central exhibit in any defense.

Liability is presumed. For damage falling under décennale, the maître d'œuvre is held liable without the client having to prove fault. To be released, the builder must show an external cause, an act of the client or force majeure. This presumption makes the traceability of observations, photos, and dates indispensable.

Coverage is mandatory. Decennial insurance must be taken out before the site opens. The reserves on the PV de réception, their location, and the date they are cleared determine what is covered and what remains the builder's charge.

Legal and regulatory framework

Article 1792 of the Code civil sets the principle: every builder is strictly liable for damage that compromises the solidity of the works or makes them unfit for their intended purpose. The loi Spinetta of 4 January 1978 structured this regime and tied it to mandatory decennial insurance and dommages-ouvrage insurance.

The 10-year period runs from réception, the milestone defined in article 1792-6 of the Code civil and recorded in the PV de réception. The garantie de parfait achèvement (1 year) and the garantie biennale (2 years) sit alongside décennale depending on the nature of the defect.

The maître d'œuvre carries decennial liability for design and execution-supervision duties. The ability to reconstruct the evidence chain, OPR, réserves, time-stamped photos, PV, levée des réserves, decides the outcome of any dispute in the 10 years after réception.

How Builddar handles decennial liability

Builddar is the construction quality operating system: every observation, every réserve, every PV de réception is time-stamped, located, photographed, and kept for 10 years. This evidence chain is exactly what a decennial-liability defense requires, and it builds automatically across the project, not the night before a dispute.

Data is hosted in the European Union. Levée des réserves, automatic reminders to subcontractors, and the PV de réception form a dated, defensible file. Coordinate with proof. Sign off with confidence.

Frequently asked questions

Responsabilité décennale is the strict 10-year liability of builders, architect, maître d'œuvre, contractors, running from the réception of the works. It covers damage that compromises the solidity of the structure or makes the work unfit for its intended purpose. It comes from the loi Spinetta of 4 January 1978 and article 1792 of the French Code civil.
The 10-year period runs from réception of the works, not from delivery or the end of the site. Réception is recorded in the PV de réception, which fixes the exact date. This is why a precise, dated PV listing the reserves is the document that determines the duration and scope of the cover.
Yes. The maître d'œuvre is a builder within the meaning of article 1792 of the Code civil and carries decennial liability for design and execution supervision. The maître d'œuvre must hold decennial insurance taken out before the site opens.
Décennale covers damage that compromises the solidity of the works, structural cracks, subsidence, major water ingress, or makes them unfit for their purpose, such as failed waterproofing. Minor defects fall under the garantie de parfait achèvement (1 year) or the garantie biennale (2 years) depending on their nature.
Decennial liability rests on a presumption: the builder is held liable without fault being proven. To be released or to limit their share, the builder must produce dated proof of the building's condition at réception, OPR, réserves, time-stamped photos, PV, levée des réserves. This evidence chain is kept for 10 years, hosted in the European Union.
