Dommages-Ouvrage Insurance: Claim Deadlines and Filing Procedure Explained

Dommages-Ouvrage insurance: why are the deadlines so critical in the Alpes-Maritimes and the Var?

Along the French Riviera, from Nice to Toulon, construction is a thriving industry. But what happens when a crack appears on a load-bearing wall, or water infiltration sets in after a Mediterranean downpour? Contrary to popular belief, the key to fast compensation isn’t just the severity of the damage — it’s strict compliance with the dommages-ouvrage (French building damage insurance) procedure’s deadlines. As an independent expert working across the Alpes-Maritimes (06) and the Var (83), I too often see property owners lose valuable rights simply because they didn’t know the ins and outs of the legal timeline. Dommages-ouvrage insurance was designed to protect you, but it is a highly procedural system. A single late declaration can turn a full payout into a long, costly legal battle. Let’s break down this high-stakes timeline together.

The preliminary phase: reporting the claim to your insurer

What are the deadlines for reporting a claim?

The starting point of the entire procedure is the moment the defect appears. The golden rule is this: you must send your claim declaration to your dommages-ouvrage insurer by registered letter with acknowledgement of receipt (LRAR) as soon as the problem is noticed. – **The contractual deadline**: Your dommages-ouvrage policy generally requires a maximum of 5 working days after discovering the damage to file this declaration. This is a very short window. As soon as you spot a spreading hairline crack or unusual damp patch, act immediately. – **The limitation period**: Beyond the immediate declaration, you have a legal window of 2 years from the appearance of the damage to take action against the insurer. Once this period lapses (the two-year statute of limitations), you forfeit any right to compensation. A word of caution for owners of villas in the hills above Nice or stone properties around Hyères: progressive defects (such as cracks linked to clay shrink-swell movement) are often deceptive. If you’re unsure when the damage first appeared, consult an expert quickly to formally document the situation.

The compensation process: the insurer’s legal deadlines

Once your registered letter has been sent, the clock starts ticking for the insurer. The Spinetta Law imposes a strict timetable on your insurer — one we must monitor closely on your behalf.

Case-opening deadline (10 days)

Upon receiving your declaration, the insurer has 10 days to acknowledge receipt and provide you with your case reference. If they fail to do so, they are exposed to penalties — but more importantly, it can be a sign that your case isn’t being taken seriously. As an independent expert, this is often the stage where I’m brought in to push the insurer and get the process back on track.

The expert assessment (15 days)

Within 15 days of your declaration, the insurer must carry out, or arrange for, an adversarial expert assessment. This is the critical moment: you must be present or represented. Across the Var and the Alpes-Maritimes, having an independent expert by your side during this visit is decisive for protecting your interests. The insurer’s own expert isn’t there to help you — they’re there to assess the cost according to the insurer’s rules.

The compensation offer: the 90-day deadline (or 105 days for serious defects)

This is the heart of the system. The insurer must present you with a compensation offer: – Within 90 days of your declaration for damage that cannot be repaired immediately (for example, a leak requiring investigation into its source). – Within 15 days for damage that can be repaired immediately (for example, a broken window). – A specific 105-day deadline applies to serious and complex defects, particularly those affecting the structural soundness of the building or rendering it unfit for its intended use. Structural issues in properties along the French Riviera often fall into this category. The offer must cover compensation at rebuilding value, project management and technical inspection fees, and any relocation costs. Be wary of low-ball offers: negotiation is possible, but the tight deadlines don’t leave much room for it.

Handling disputes: what to do in case of silence or refusal

The 15-day window to accept or reject the offer

Once you receive the offer, you have 15 days to accept it. If you accept, the insurer then has 30 days to pay you the funds.

Forfeiture and arbitration

If the insurer fails to meet these deadlines, they face a 20% penalty on the compensation amount, plus 1% for every month of delay. However, be careful: if you don’t respond, or if you reject the offer, the process can stall. Before going to court, a simplified arbitration procedure is available in certain cases. In all cases, if you’re facing an inadequate offer or a complex claim, appointing a court-appointed expert may become necessary. This step is highly technical and considerably longer. This is exactly why bringing in a dommages-ouvrage expert from the outset is essential to avoid these bottlenecks.

Points of local concern in the PACA region (06 and 83)

Beyond the legal deadlines, years of practice across the Alpes-Maritimes and the Var have taught me to watch for local factors that affect the procedure: 1. **Natural hazards**: Clay shrink-swell movement (drought-related ground movement) is a major issue in the hinterlands of Nice and the Var. Insurers often request extra time to study soil conditions, but they cannot bypass the legal 90-day deadline without proper justification. 2. **Construction in seismic zones**: Classified as a moderate-to-high seismic risk area, the region is subject to earthquake-resistant building standards. Damage affecting these specific elements requires highly specialised assessments, which extend the timeline for reaching an amicable resolution. 3. **Multiple trades involved**: For co-ownerships and individual homes built by developers or single-family home builders (CMI), managing deadlines becomes more complex. Completion guarantees and guarantees of perfect completion often overlap with dommages-ouvrage cover, creating timeline confusion that works against the claimant. **Advice from a seasoned building professional**: Never underestimate the importance of declaring immediately. Waiting for a crack to widen « just to be sure » is your worst enemy. A claim not declared in time becomes a claim that isn’t covered. Keep a copy of every letter and note the dates you received them, because the burden of proof falls on you.

Frequently asked questions

What is the deadline for declaring a dommages-ouvrage claim?

The deadline for declaring a claim is 2 years from the handover of the works. This deadline is strict, but it’s best to declare as soon as the problem appears in order to speed up the process.

How does the dommages-ouvrage claim declaration procedure work?

You must send a written declaration to your dommages-ouvrage insurer describing the damage and its causes. The insurer then has 60 days to respond and may appoint an expert to assess the damage.

What happens if I declare my claim after the 2-year deadline?

If you go beyond the 2-year deadline, your declaration will be rejected as inadmissible. You lose the dommages-ouvrage cover, but you can still take action against the builder under the ten-year structural warranty, within its own limitation periods.
