Renting out a room or kot in Belgium: do you need a permis de location?

Every few weeks we get the same message from a landlord who's just listed their first room: "do I actually need a permit for this?" The answer depends on where the property is, and it's exactly the part most new landlords in Wallonia don't know about until a tenant complaint or an inspection forces the issue.

Do I need a rental permit to rent out a room in Wallonia?

Yes, in two specific situations. The permis de location is mandatory for any individual home under 28m² used as a primary residence or student kot, and for any "logement collectif": a property where the kitchen, bathroom or toilet is shared between separate households, which is exactly the structure of most colocations and shared flats.

There's one relevant exception: if the landlord lives in the same property and rents out no more than two rooms to a total of four tenants, no permit is required. Go beyond that threshold, or if the landlord doesn't live on-site, and the permit becomes mandatory.

How much does the permis de location cost in 2026?

The cost depends on the type of property. For an individual home, the maximum fee is €210 excluding VAT. For collective housing, that becomes €210 as a base fee plus roughly €41 excluding VAT per individual room, so a four-room colocation can run to around €374 in inspection fees. Once granted, the permit is valid for 5 years.

What happens if I rent out a room in Wallonia without a permit?

The administrative fine runs from €250 to €12,500 per dwelling, issued by the regional sanctioning official following the municipal inspector's report. Beyond the fine, non-compliance can trigger an order to bring the property up to standard, withdrawal of an existing permit, and in the most serious cases criminal penalties, including possible nullity of the lease itself.

It's worth weighing this alongside the rest of a landlord's tax obligations, which we cover for the Luxembourg case in renting out a room in Luxembourg: what landlords must declare; the underlying logic, handling the paperwork before listing rather than after, is the same in both countries.

Does Brussels work the same way?

No. Brussels doesn't use a permis de location system like Wallonia. Instead, the Brussels Housing Code sets minimum quality standards (surface area, natural light, a kitchen or kitchen area, safety conditions) that every rented property must meet, checked through inspection rather than a prior permit. Non-compliance is penalised with administrative fines of €2,000 to €25,000 per dwelling, a considerably higher range than Wallonia's.

This regional difference confirms something we've already documented: Belgium doesn't run on a single housing law, but three distinct regimes depending on the region, as we also explain when comparing Flemish rental rules against Brussels.

What does this mean for someone searching or listing on Roomie-Radar?

If you're about to list a room or kot in Wallonia, check beforehand whether your property falls under either of the two situations that require the permit; sorting it out after applications start coming in only slows things down. Many of our landlord users in Wallonia tell us that handling the permit before publishing the listing, rather than in parallel, avoids having to pause an already-occupied colocation. Roomie-Radar connects landlords with qualified users searching for a room in Belgium, and using Roomie-Radar is free.

Conclusion

The permis de location isn't an optional step for anyone renting out a room or kot in Wallonia: it applies to most colocations by definition, costs a few hundred euros, and skipping it exposes landlords to fines that can far exceed that initial cost. Brussels solves the same underlying problem with minimum quality standards instead of a prior permit, but the end goal, guaranteeing decent housing, is the same across all three Belgian regions.

If you're a landlord weighing your first room listing in Belgium, confirm which regime applies in your region before setting a move-in date. At Roomie-Radar we help make sure that first listing starts with the right information from day one. Start at roomie-radar.com.
