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
- Zone UCb: before an extension, a shed or a division, read this zone’s rules (height, footprint, setbacks from the street and the boundaries). Guide: Turn the map finding into a specific question
- 2 prescriptions, information areas or easements touch the parcel (details below): they apply on top of the zone’s rules. Guide: Read the documents, not just the colour
- Clay soils: Medium exposure (100% of the parcel). General rule in medium or high exposure areas: the seller of unbuilt buildable land supplies a preliminary geotechnical study where planning rules permit individual houses. Exposure alone does not establish that this sale is covered. Construction projects are subject to separate rules to check with the professional. Géorisques: soil studies and construction
- PER - Montbonnot-Saint-Martin covers 100% of the parcel: its rules may forbid or restrict building; read them before any project. Guide: Identify the scope of each finding
- Seismic zone 4 (medium): a new house must follow the earthquake-resistant building rules. Guide: Identify the scope of each finding
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
UCb – Urban zone (U)
Urban zone family. This category does not establish permission to build: check the local code, applicable rules and parcel constraints.

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.
