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.
