How do you check a plot in Brussels, step by step?
Start with the zoning in the PRAS and any PPAS, then read the building rules of the RRU and the municipality, and check heritage, permits, soil, water and pre-emption. In Brussels each step has its own register; the municipality’s planning information brings much of it together.
Seven steps, seven places
| Step | Where to find it | Who knows |
|---|---|---|
| 1. The zoning | BruGIS and ppas.brussels | perspective.brussels and the municipality |
| 2. The building rules | the RRU and the municipal regulations | urban.brussels and the planning office |
| 3. Heritage | monument.heritage.brussels | urban.brussels |
| 4. Permits | the municipal archive and openpermits.brussels | the planning office |
| 5. Soil | the soil status inventory and the soil certificate | Brussels Environment |
| 6. Water | the 2025 flood map | Brussels Environment |
| 7. Pre-emption | the decisions in the Belgian Gazette (Moniteur belge) and BruGIS | the notary checks it |
A purchase involves other points too, such as planning information in Brussels and the Brussels checklist. What a report on an address costs is listed under Perceelscan pricing. You can work out the taxes on a purchase for free with the registration duties calculator and the property tax calculator.
At each step
What is allowed: see the guide to zoning. Heritage: listing and inventory. Whether the building is permitted: permits and regularisation. Soil: the soil certificate. Water: the flood map. A right of pre-emption: the pre-emption perimeters.
The planning information brings much together
The municipality’s planning information combines steps 1, 3, 4 and 7 for one property. The seller requests it; as a buyer you ask for it before your offer. It reflects the state of the municipal archive: comparing the drawings with the building is still your job, or your architect’s.
What is in no register
The state of the roof, damp in the cellar, asbestos, the neighbours and their plans: for that you go and look on site, talk to the neighbours and bring an architect or contractor. The cadastral map of the plot is in CadGIS of the FPS Finance, the same for all of Belgium.
What the Perceelscan says about it
Steps 1 to 7 for one address in a single report, each answer with its source and the day it was retrieved. The preview per address is free.
Where do you find the cadastral map of a plot in Brussels?
In CadGIS, the map of the FPS Finance. The cadastre is federal: it works in Brussels as in the rest of Belgium.
