Address from France’s national address register (BAN), associated with this parcel for information only. Addresses and how they are linked
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. Boundary marking (Service Public, in French)

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).
Addresses
Source: Base Adresse Nationale (national address register). “Linked by its position”: the address point lies inside the parcel. “Linked by its building (RNB)”: the building that carries the address in the national building register (Référentiel National des Bâtiments) stands on the parcel. “Linked by IGN (BAN PLUS)”: IGN matches the address to this parcel, the nearest one on the same side of the street, and the address point lies inside it. In these cases the Base Adresse Nationale declares no link.

Local plan prescriptions
For guidance only, from the Géoportail de l'Urbanisme extraction of 15 August 2026; the linked document may have been replaced since. Only the planning document's regulations and annexes are binding. A missing item means “not recorded”, not “no constraint”.
National clay exposure (BRGM/Géorisques) and labels in the local planning document are separate sources: dates, methods and purposes may differ. Both values are retained; neither replaces the other. Check the national map and local rules with the authorities. Data versions: national clay layer 2026-07-02; GPU extraction 2026-08-15. Géorisques: soil studies and construction

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.
