The parcel (in colour) and its neighbours, from the cadastre; computed perimeter: 136 m. North is up; the bar gives the scale.
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)

Understanding the map information

Planning zoning

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.

Buildings

Indicative data (IGN BD TOPO): buildings IGN links to the parcel (BAN PLUS) when they cover at least 20 m² of it, with information from the tax files (DGFiP), anonymised. An unknown height or number is not shown. Construction years are grouped into periods, because old buildings often carry an estimated round year (1800, 1900…). A building standing on several parcels is counted on each, with all its dwellings. Recent buildings may be missing: the tax files are updated with a delay.

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.
