The cadastre is a tax record: it does not prove ownership. Why?
The cadastre is a tax record: it does not prove ownership and its boundaries have no legal force (only a surveyor's boundary marking does). Its plan is approximate: especially where it is old, it can be offset by a few metres from the buildings and the aerial imagery. The owner's name is not shown.

What this means for a project
- Commune under the RNU: building is in principle limited to the already built-up parts of the commune; a certificat d’urbanisme says what is possible on this parcel. Guide: Use a planning certificate for the next step
- Radon potential category 3: it appears in the information given to buyers and tenants; ventilating and, during works, sealing between the ground and the building reduce exposure. Guide: Prepare the formal risk statement
Points drawn from this parcel’s data. They tell you which questions to ask; they do not replace a certificat d’urbanisme or the official statement of risks.
Understanding the map information
- French planning: who decides what
- The public data behind the map
- Reading and finding a cadastral reference
- Cadastre and boundary surveys: where does the land end?
- Reading a PLU: a zone label does not define a project
- Recorded and calculated parcel area: why two figures?
- Addresses and parcels: why they do not always match
- Parcel owners: what the map does not show and where to ask
- Dividing a plot: preparing a land division
- Property risks: from a map finding to a proper check
Planning zoning
No PLU: the commune follows the national planning rules (RNU).

Risks
This information is for guidance only and has no regulatory force: it does not replace the risk statement (état des risques, ERRIAL) to be attached to a sale or a rental, which anyone can produce free of charge on Géorisques.
Some clay soils swell when wet and shrink as they dry, which can crack buildings. The higher the exposure, the more building precautions are needed. A risk prevention plan (PPR) maps the areas exposed to a hazard (flooding, ground movement, an industrial site…) and sets building rules there. The Géoportail de l'Urbanisme does not list every plan yet.
