- Flood risk is listed: check the risk statement for the property and, if there is one, the prevention plan attached to the local urban plan.
- Significant radon potential: a risk statement must be attached to the sale or lease; the radon level in the home can be measured.
- Before buying into a co-ownership: ask for the minutes of the last three general meetings, the maintenance log, the amount of the works fund and the state of unpaid charges.

🌊 Natural hazards
Hazards listed for the municipality:
Natural disaster declarations per year (since 1982)
5 declarations in total, 1 of them in the last ten years
| Indicator | Value |
|---|---|
| “floods and mudslides” declarations | 5 |
| “ground movements” declarations | 1 |
| Radon potential (class 3 of 3) | Significant |
A declaration recognises a state of natural disaster for a given event; it triggers the “natural disasters” cover of home insurance policies and of the building’s insurance. “Drought” declarations relate to the shrinking and swelling of clay soils, a frequent cause of cracks in buildings. A risk statement (état des risques) must in particular be attached to a sale or lease when the property lies in an area covered by a prevention plan, in seismic zone 2 to 5, or with a class 3 radon potential. This page presents municipal data: it does not replace the risk statement drawn up for the property’s address.
