The Brussels-Capital Region regulates short-term rental as tourist accommodation (hébergement touristique / toeristisch logies), under a regional ordinance from 2014 that was updated in 2024. Before renting out an apartment or a room to tourists, the operator must register the accommodation and show that the use complies with planning rules and fire safety requirements. Enforcement stepped up sharply in 2025, and part of the framework is being challenged before the EU Court of Justice. This guide explains the position in October 2026. It is general information, not legal advice, and the rules are unsettled enough that a specific case is worth checking with the Region or a local adviser.
| Rule | What applies |
|---|---|
| Registration | Prior registration of the tourist accommodation with the Region |
| Planning | Urbanism compliance for the use, from the municipality |
| Fire safety | Fire safety certificate from the fire service |
| Building | Co-ownership rules can prohibit short-term rental |
| City tax | Regional tax per unit per night, not per guest |
Registration with the Region
Tourist accommodation must be registered with Brussels Economy and Employment, the regional administration, before it is offered. The registration covers the type of accommodation, the address, the operator and the number of guests, and it produces a registration number that must appear on every listing. Under Regulation (EU) 2024/1028, which applies from 20 May 2026, platforms must check that the number is present and remove listings the authority flags.
Hosts renting a room in the home they live in, and hosts renting a whole home, fall into different categories with different requirements, so the first step is identifying which category the accommodation belongs to.
Planning compliance and fire safety
The registration depends on two further documents. The first is proof that the use of the property as tourist accommodation complies with planning law, which in many cases means a planning permit or a certificate from the municipality’s urbanism department; municipalities apply their own policies, and several restrict tourist accommodation in residential buildings. The second is a fire safety certificate from the Brussels fire service (SIAMU / DBDMH), issued after an inspection, which checks alarms, escape routes and equipment against the standard for the size of the accommodation.
It is these prior authorisations that are being contested. In the SmartFlats case, the EU Court of Justice was asked whether requiring several authorisations, including planning compliance, before renting is compatible with EU law on services. The Advocate General’s opinion found the Brussels rules disproportionate and insufficiently transparent. An opinion is not a judgment, and until the Court rules and the Region responds, the current requirements still apply.
Co-ownership rules
In an apartment building, the co-ownership’s rules (statuts / statuten) can prohibit or restrict short-term rental, and the general meeting can vote to change them. A registration from the Region does not override the building’s rules, so check them before investing in furnishing an apartment for short stays.
The regional city tax
The Region charges a city tax on tourist accommodation per unit per night, not per guest, which makes it unusual among European cities. For a typical apartment it is around €5 per night in 2026, with different amounts by category. Tax demands have been issued retroactively for accommodation found operating without registration, so a missing registration can carry a tax bill for past nights as well as a fine. Because the tax is per unit, it is simply the nightly amount times the nights; it does not change with the number of guests, which matters when comparing Brussels with cities that charge per person.
Enforcement
Enforcement increased markedly in 2025, with the Region issuing large numbers of fines to unregistered hosts, reported at €1,000 or more per case, plus back tax. Hosts have a limited window to contest a fine or regularise. The new regional government has been urged to simplify the framework, and changes are possible, but the rules described here are those in force in October 2026.
Flanders and Wallonia are different
Belgium regulates tourism by region. Flanders requires registration with Toerisme Vlaanderen and a fire safety certificate for larger accommodation; cities such as Ghent and Antwerp add their own rules and taxes. Wallonia requires a declaration to the Commissariat général au Tourisme. A portfolio spanning Belgian regions is effectively under three regimes.
If you manage for owners in Brussels
Because the registration, planning and fire documents are all tied to the property and its use, gather them before taking on the property, not after the first booking. For each unit, record the registration number, the planning basis and its date, the fire certificate and its renewal, any co-ownership restriction, and how the city tax is charged and declared for each channel. Short-term rental management software keeps those documents and dates on the property record.
How Brussels compares
Amsterdam and Paris cap the nights a home can be let, London does the same through planning law, and Lisbon restricts registrations through containment zones. Brussels has no night cap; it controls short-term rental through the documents needed to register.

Common questions
Do I need to register my Airbnb in Brussels?
Yes. Tourist accommodation in the Brussels-Capital Region must be registered with Brussels Economy and Employment before it is offered, and the registration number must appear on every listing.
Is there a night limit for short-term rentals in Brussels?
No. Brussels does not cap nights per year. It controls short-term rental through registration, planning compliance and a fire safety certificate.
How is the Brussels city tax on short-term rentals calculated?
Per unit of accommodation per night, not per guest. For a typical apartment it is around €5 per night in 2026, varying by category.
What is the SmartFlats case?
A case before the EU Court of Justice on whether the Brussels requirement to obtain several authorisations, including planning compliance, before renting out tourist accommodation is compatible with EU law. The Advocate General found the rules disproportionate; the Court’s judgment is what will decide.
