Parcel 31555 843 AH 203

Cadastral parcel of 4,054 m² (recorded area), in Toulouse. Local plan (PLU) zones: NL and UA1.

Recorded area: 4,054 m²
PLU zone: NLNatural and forest zone (N)

The parcel (in colour) and its neighbours, from the cadastre; computed perimeter: 382 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 NL: new buildings are in principle excluded; a measured extension of an existing home may be allowed where the rules provide for it. Guide: Turn the map finding into a specific question
Zone UA1: 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
The parcel is split between 2 zones: each part follows the rules of its own zone. Guide: Read the documents, not just the colour
10 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). With medium or high exposure, selling a building plot requires a preliminary soil survey, and a new house must follow adapted building rules. Guide: Prepare the formal risk statement
PPR Secheresse de Toulouse covers 100% of the parcel: its rules may forbid or restrict building; read them before any project. Guide: Identify the scope of each finding

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: Medium exposure (100% of the parcel)
Risk prevention plan: Natural or mining risk plan (PM1) – PPR Secheresse de Toulouse – 100% of the parcel
Seismic zone: Zone 1 (very low)
Radon potential: Category 1 (low)
