On forums, off-plan (VEFA) buyers on the French Riviera keep asking the same questions: delivery delays, [construction faults](https://cassini-expertise.fr/contre-expertise-batiment-06-83/), non-compliant floor areas, [cracks](https://cassini-expertise.fr/diagnostic-fissures-rga-06-83/). Here are the most common issues, construction faults, and the role of the building expert.

*Cassini Expertise – independent building expertise*

On the French Riviera ([Nice](https://cassini-expertise.fr/nice-secheresse-argile-fissures-donnees-officielles/), Marseille, Cannes, Antibes), construction site delays are common with off-plan purchases. The building expert steps in to: assess actual site progress, evaluate the technical causes of delay (ground conditions, weather, subcontractor failures), and assist the buyer at handover to check compliance.

## Hidden defects and construction faults in VEFA

The most common issues on the French Riviera:

- **[Cracks](https://)** caused by clay shrinkage-swelling (very common in the Var and Alpes-Maritimes)

## Closing out reservations: a key moment

At handover, the expert helps the buyer draft a detailed reservations report (with photos and measurements), tracks the developer’s resolution of those reservations, and estimates the cost of any work that is missing or poorly done.

## Court-ordered expert assessment

If the developer fails to respond or disputes the defects, the court-appointed expert can order test borings, waterproofing tests and acoustic measurements. Their report carries weight before the judge.

## Questions from the forums

**“My developer in Nice is 6 months behind schedule”**: penalties apply (1/3000th of the price per day). Have the delay formally recorded by an expert.

**“I have cracks 2 years after delivery”**: the [10-year structural warranty](https://cassini-expertise.fr/expertise-dommages-ouvrage-06-83/) (decennale) runs for 10 years. An expert determines whether the structural soundness is compromised.

**“The Carrez floor area doesn’t match the contract”**: if the discrepancy exceeds 5%, you’re entitled to a proportional price reduction. A surveying expert measures it precisely.

## Frequently asked questions

### VEFA delivery delay compensation?

In a VEFA purchase, if the property is delivered more than 30 days late, the buyer can claim late-delivery penalties, typically set at 1/3000th of the price per day of delay, barring force majeure. This compensation applies automatically once the deadline is exceeded, without prejudice to a separate damages claim.

### Hidden defects in VEFA – recourse against the developer?

Yes, a VEFA buyer benefits from the 10-year structural warranty (decennale) covering damage affecting structural soundness or making the home unfit for its purpose, and from the one-year completion warranty for all defects reported at handover. For hidden defects not visible at handover, a claim can be brought within 2 years of discovery, but it’s essential to notify the seller by registered letter.

### VEFA construction defects – can I refuse handover?

At handover, you can refuse to sign if major defects are found, but the refusal must be justified and formally notified. In case of disagreement, a court-ordered expert assessment can be requested. It’s advisable to list every defect on the handover report, even if you sign with reservations, in order to preserve your rights.
