The most searched questions, answered briefly Regulations and land registry How do I find a plot's cadastral nature with a cadastral extract? The cadastral nature (house, flat, land…) and the area are shown on the cadastral extract from FPS Finance, which you can request online on MyMinfin. Online, the extract is free for your own properties and costs €5 for a third party's property; most arrive within 48 hours. Read the full answer → Regulations and land registry How do I convert the cadastral area into m²? 1 hectare (ha) = 10,000 m², 1 are (a) = 100 m² and 1 centiare (ca) = 1 m². A plot of 0 ha 2 a 30 ca therefore measures 230 m². Read the full answer → Planning data What is the map of vicinal roads and paths for? It shows the roads and paths recorded in the Atlas des chemins vicinaux (Atlas of Vicinal Roads, 1841). A recorded road remains public even if it cannot be seen on the ground or is missing from the land registry: building on it requires a procedure to modify or close the road, before or alongside the permit application. Read the full answer → Planning data How do I check whether there is a runoff path or flood zone nearby? In the Contexte column or the project's visualisation tool, switch on Toutes les couches (all layers), then the Inondations et ruissellement (floods and runoff) theme. The risk can affect your project even if it lies on a neighbouring plot: the permit may be refused or granted subject to conditions (Article D.IV.57, 3° of the CoDT).

The technical report is required when the Water Code rules applicable to the project call for it, extensions included, including to show that infiltration is not possible. Otherwise, a short note on water management is still advisable. Read the full answer → Planning data Where can I find my plot's centrality zone? Video Airplan detects the SDT centrality type of your plot and shows it in the Contexte (context) column, the feasibility study and the map set. It serves as a reference, particularly for unsealed ground, without determining the buildable area on its own. Read the full answer →
