Brussels has been playing hardball with illegal Airbnb hosts, and the numbers are starting to show. The Brussels-Capital Region expects to collect up to six million euros in fines by the end of 2026, according to the region's Taxation minister, Dirk De Smedt. That's a serious chunk of change, and it signals just how far the city is willing to go to rein in the short-term rental market.
The rules have been on the books since 2016. Every Airbnb property in Brussels must be registered with city authorities, and owners are on the hook for a tourist tax of five euros per night, or four euros if they're renting out a room in their own home. But registration is just the start. Hosts also need fire safety certificates, clean criminal records, and must comply with urban planning rules. The goal, as Brussels Councillor Anaïs Maes put it, is to keep the city center from becoming a ghost town of holiday lets and to protect the housing market for residents. It's a battle that cities like Amsterdam and Barcelona know all too well.
Despite the crackdown, many hosts have continued to fly under the radar. A 2022 European Court of Justice ruling forced Airbnb to share listing data with Brussels Taxation, but that hasn't stopped everyone. An investigation by Bruzz earlier this year found that a staggering 90% of Brussels Airbnb listings were not compliant with local laws. Out of 3,637 active listings, only 267 were on the official list of approved rentals. That's less than 10% playing by the rules.
The city has been aggressive in chasing down the offenders. Over 2025 and 2026, at least five million euros has already been recovered through inspections and backdated taxes. Non-compliant owners face a €1,000 fine per rental, plus unpaid tourist taxes. And here's the kicker: unless owners can prove otherwise, the tax authorities assume the property was rented out all year. That can add up fast.
For travelers, this means the Airbnb landscape in Brussels is shifting. If you're booking a stay, it's worth checking whether your host is actually registered. The official list is public, and a quick search can save you from supporting an illegal operation. It also means the city is serious about keeping housing affordable for locals, which is something to keep in mind when you're choosing where to stay.
But there's a glimmer of hope for hosts. Starting 1 January 2027, the rules are set to loosen up. Brussels minister-president Boris Dilliès (MR) is pushing through changes that will exempt rentals within a primary residence from urban planning certification. Safety compliance will also become less burdensome, and co-owners will no longer have a say in whether a unit can be rented out. That's a big deal for anyone who's been blocked by a homeowners' association.
Still, this isn't a free pass. Even with the relaxed rules, properties must be properly registered and the tourist tax still applies. So the days of operating in the shadows are numbered, even if the paperwork gets a little easier.
And if you're a guest, there's another change to note. Airbnb has finally banned the worst checkout chores. No more being asked to strip beds, haul trash, or run the vacuum as if you were the cleaning crew. The company says guests shouldn't be expected to do anything "onerous" or time-consuming. It's a small victory for travelers everywhere, and you can read more about it in our piece on Airbnb's new checkout rules.
Brussels is also making headlines for other reasons. If you're planning a visit, you might want to check out the museums that stay open until midnight for one special night, or the new airport booths designed to cut down on border wait times. And for a taste of local culture, there's the Mugham music event that recently took the city by storm.
The bottom line: Brussels is cleaning up its short-term rental act, and the message is clear. Register, pay your taxes, or face the consequences. For travelers, that means a more transparent market and, hopefully, a fairer deal for everyone involved.
