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

The parcel (in colour) and its neighbours, from the cadastre; computed perimeter: 107 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.

What this means for a project

Zone UC: 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
13 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: High 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
Natural or mining risk plan (PM1) covers 55% of the parcel: its rules may forbid or restrict building; read them before any project. Guide: Identify the scope of each finding
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

Planning zoning

UC – 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.

On the parcel: 3 buildings
1 of them also stands on other parcels; dwellings are counted for the whole building
Use: Residential
Height to the eaves: up to 7 m
Storeys: up to 2 (ground floor included)
Dwellings: 2
Built: 1901 – 1949

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.

Clay shrink-swell: High exposure (100% of the parcel)
Risk prevention plan: Natural or mining risk plan (PM1) – 55% of the parcel
Seismic zone: Zone 2 (low)
Radon potential: Category 3 (significant)

Produce the risk statement (ERRIAL) on Géorisques Risks near an address (Géorisques)
