France
Climate
Metropolitan France spans Atlantic, continental, mountain and Mediterranean climates. Rain, winter cold, snow and summer heat vary significantly. Overseas territories require separate local cyclone, seismic and climate guidance.
Geographic hazards
- Floods & coastal storms
Check river, surface-water and coastal risks in local plans. Storm exposure on Atlantic coasts and drainage conditions inland can affect both buildings and access.
- Heat, drought & ground movement
Clay soils can shrink and swell during changing moisture conditions. Ask about ground investigations, cracking history and foundation design.
- Earthquakes & mountain hazards
Seismic exposure is more relevant in some regions, including Alpine and Pyrenean areas. Mountain sites may also need snow-load, landslide and avalanche information.
- Wildfire
Mediterranean and other vegetation-exposed sites need local fire restrictions, access and management checks. Do not extrapolate a mainland profile to an overseas territory.
Insects and rot
Ask the mairie whether the property is in a declared termite area and obtain applicable diagnostic information. Inspect roof/floor timber for other wood-boring insects, and investigate leaks and damp that may cause fungal decay. An insect report is not a complete moisture survey.
Best-fit building approaches
- Insulated masonry & brick assemblies
Insulated masonry can suit many locations when foundations match the soil and the structure meets local seismic rules. Moisture detailing and summer shading remain important.
Read the brick guide - Engineered timber framing
A well-engineered timber frame can also suit cold or temperate regions, with a drained envelope, controlled condensation and site-appropriate pest and wildfire detailing.

Buyer checks
Review local risk information, clay-soil exposure and relevant planning restrictions.
Confirm termite-area status and obtain the applicable property diagnostics.
Appraise older masonry, additions and region-specific snow/seismic requirements.

These official resources help you ask better questions; they do not provide a parcel-level risk assessment. A map does not guarantee safety, and an unmapped or blank area does not mean no hazard. We do not assign automatic property risk scores.
- Collect the address, region/municipality, cadastral parcel reference and coordinates from the seller or surveyor. Check the map pin against the actual plot, not just the postcode or village centre.
- Open the relevant resource below. Where there is no address search, use coordinates, local landmarks or the named regional map sheet. Check the plot, access roads and evacuation routes.
- Read the legend, scale, publication date, model scenario and coverage. A “100-year” event is a probability scenario, not a promise of one event per century. Check current official warnings separately before visiting.
- Ask the responsible authority for the latest local study and restrictions. Give the findings to a qualified surveyor, structural/geotechnical engineer and insurer before relying on them in a purchase.

Géorisques — address and parcel risk information
Authority: French environment ministry and BRGM
Hazards: Flood/coastal inundation, seismic zoning, clay movement, cavities, landslides and wildfire information
Coverage: France; availability differs by commune and overseas territory.
How to locate the property: Use the address or parcel search (Connaître les risques près de chez moi), check the pin against the cadastral location and read the risk report and local prevention-plan layers. Ask the mairie for the applicable PPR and property disclosures.
Limits: Layers have different scales and dates, and not every hazard is mapped everywhere. Overseas cyclone and volcanic checks require territory-specific advice; a report is not a safety certificate.
Editorial review: 2026-10-14. Published edition [not-recorded]: Edition or layer dates were not recorded in the initial research; verify with the publisher. This is not a live status or property assessment.
Temporary service notice: A maintenance notice was observed on 14 October 2026. This is not a live service-status check; retry or contact the mairie/BRGM. Recheck by 2026-10-15.
Confirm locally — including gaps in mapping
Confirm the current PPR, coastal setbacks, wildfire obligations and ground restrictions with the mairie and préfecture (or responsible overseas services). Where a layer is missing, request the local study; have clay, cavities, slopes and structural condition assessed professionally.
