Wallonia
Anyone offering tourist accommodation in French-speaking Wallonia must register it with Tourisme Wallonie before renting it out. Registration is free and done online. You must provide your identity, the address and capacity of the accommodation, a fire safety certificate (ASI) or simplified inspection certificate (ACS), and a criminal record extract less than six months old. Since 30 January 2023, creating new tourist accommodation in an existing building generally requires planning permission. Without registration, the administrative fine ranges from €400 to €40,000.
Brussels
The accommodation must be registered with Brussels Economy and Employment before letting to tourists, even occasionally. The file includes a fire safety certificate, a planning compliance certificate from the local council, a floor plan and photos; third-party liability insurance is also required. You then receive a registration number. The accommodation must also be declared to Brussels Taxation for the regional tax on overnight stays. The planning compliance certificate is often the hardest step.
Flanders
Anyone accommodating tourists for payment must notify Toerisme Vlaanderen (aanmelding) and meet basic conditions: a positive fire safety certificate, insurance, cleanliness and upkeep. The accommodation receives a registration number and appears in the online register. Official recognition is possible but optional.
The EU regulation, since 20 May 2026
Regulation (EU) 2024/1028 provides for a unique registration number for each unit let on a short-term basis. Platforms must display it and must not publish listings without a valid number. The regions are adapting their rules accordingly.
Other things to check
- Co-ownership: the building’s deed or house rules may restrict or ban holiday lets.
- Tenants: if you rent the home yourself, you need the owner’s written consent.
- Taxes: local or regional tourist tax, and income to declare.
A stay of several months as a main residence falls under residential lease law: see our guide to short-term leases. Looking for accommodation in Charleroi? Discover SofieFlat.
