Brussels Airbnb supply falls 23% as tax enforcement reshapes the short-stay market
Airbnb’s available short-term rental supply in the Brussels-Capital Region fell from 6,171 listings in June 2025 to 4,750 in June 2026, a 23% year-on-year decline linked to a regional tax and regularisation campaign.
A smaller short-stay market affects three groups directly: residents seeking rental housing, hosts relying on supplementary income and visitors looking for alternatives to hotels. Enforcement may return some tourist units to conventional leases, but it can also reduce visitor choice and raise compliance costs for small hosts.
Airbnb’s available short-term rental supply in the fell by 23% in the year to June 2026, dropping from 6,171 listings to 4,750, according to Inside Airbnb data reported by L’Echo and BRUZZ on 10 July. The contraction was particularly sharp in , where availability fell by 35.8%, and , where it declined by 34%; the recorded a smaller but still substantial decrease of 15%.
The figures point to a significant change in the capital’s accommodation market, although they require careful reading. Inside Airbnb collects publicly visible platform data, so its snapshots measure listings available through Airbnb rather than an official register of distinct, continuously operating homes. A listing may disappear because its owner stopped renting, moved to another platform, temporarily blocked the calendar or altered the property’s status. The data therefore establish a sharp fall in visible supply, but not the precise number of dwellings returned to long-term occupation.
Enforcement nevertheless appears to be an important part of the explanation. BRUZZ, citing L’Echo, reported that issued roughly 1,900 fines during the main regularisation drive and recovered an estimated €1.5 million to €2 million in unpaid taxes. Those totals have not been independently published in a detailed enforcement report, so they remain attributed figures rather than audited final accounts.
The official rules are unambiguous on the central obligation. says anyone offering a room or dwelling through Airbnb, Booking.com or a comparable platform must register the accommodation before beginning operations and comply with the applicable conditions. Operating without registration is unlawful whether the host is a private individual or a company. Hosts must also report overnight stays to so that the regional tourist tax can be calculated.
Earlier reporting showed why the authorities intensified their attention. An April 2026 BRUZZ investigation compared a regional list of recognised accommodation with Airbnb activity data and estimated that fewer than one in ten entire-home listings were correctly registered. The comparison was imperfect because the official register and Airbnb classify properties differently, and one recognised establishment can cover multiple units. Even with those limitations, it exposed a large compliance gap rather than a marginal paperwork problem.
The decline does not mean tourism itself has collapsed. recorded 9.63 million overnight stays in recognised accommodation in 2025, only 1.7% below the 2024 record. Hotel occupancy reached 75%, up 1.3 percentage points, while business travel accounted for 53.5% of overnight stays. The tourism agency also observed that accommodation supply on collaborative-economy platforms had already fallen by 5% in 2025, with the decline accelerating after the regional regularisation campaign began. The latest Airbnb snapshot therefore looks more like a restructuring of where visitors stay than a simple disappearance of demand.
For households, the practical question is whether fewer tourist listings will translate into more homes under conventional leases. planning alderwoman Anaïs Maes has said enforcement by the municipality helped return 515 illegal tourist units to the housing market. VRT NWS previously reported that municipal authorities sealed seven unauthorised tourist units near the Saint-Géry district in 2025 after the operator failed to regularise them. Such interventions can restore individual homes, especially in central neighbourhoods where short-term rentals are concentrated, but the regional Airbnb decline cannot automatically be converted into an equivalent gain in long-term housing.
The immediate effect for hosts is clearer. Commercial operators using ordinary housing as year-round tourist accommodation face registration, planning, fire-safety and tax requirements, as well as the possibility of fines or closure. Occasional hosts may lose supplementary income if compliance costs are too high. Visitors, meanwhile, may encounter fewer apartments, less choice in particular municipalities and potentially greater reliance on hotels or licensed aparthotels. Hotels gain from tighter enforcement against operators they regard as unregulated competitors, although Brussels’ expanding hotel capacity may limit upward pressure on room prices.
The policy is also becoming more selective. On 9 July, one day before the new supply figures were reported, the Brussels government approved implementing rules intended to simplify occasional home sharing from 1 January 2027. According to BRUZZ, an owner-occupier renting a room in a principal residence, or the entire residence for fewer than 90 days a year, will no longer need a municipal urban-planning certificate. Professional operators renting properties in which they do not live will continue to require planning authorisation. The distinction seeks to preserve the original model of residents earning occasional income while maintaining tighter controls on housing converted into full-time visitor accommodation.
That balance sits within a wider European shift towards traceability. , applicable since 20 May 2026, harmonises how short-term rental platforms share activity data with public authorities where registration systems exist. It does not dictate how many rentals Brussels may allow, but it is designed to make registration numbers, hosts and booking activity easier to verify across platforms. Better data should eventually reduce reliance on web-scraped estimates and make enforcement more consistent.
The next test will come in 2027. If simplified rules bring genuine owner-occupiers into the legal system while professional supply continues to contract, Brussels may end up with a smaller but more transparent short-stay sector. If listings simply migrate to other platforms or remain undeclared, the apparent Airbnb decline will overstate the policy’s success. Regional authorities will need to publish registration, tax, enforcement and housing-return figures on a comparable basis before the full economic result can be judged.
Impact
Regional — Forest and Etterbeek recorded the steepest reported year-on-year reductions, at 35.8% and 34% respectively, while the City of Brussels recorded a 15% fall. The consequences will be strongest in central and tourism-heavy neighbourhoods where short-term rentals are concentrated.
Local — The contraction varies substantially by commune. Forest recorded a 35.8% year-on-year fall in available Airbnb listings, Etterbeek 34% and the City of Brussels 15%. Effects are likely to be most visible in central and tourism-heavy areas where short-term accommodation is concentrated. Residents may see some units return to conventional rental use, while compliant hosts face less platform competition and visitors may encounter fewer non-hotel options. The figures do not establish how many withdrawn listings became long-term homes.
International — The Brussels enforcement drive now operates alongside EU Regulation 2024/1028, whose short-term rental data-sharing rules have applied since 20 May 2026. The framework is relevant to Airbnb’s cross-border operations through Airbnb Ireland UC and is intended to give public authorities more structured platform data. For EU staff and other international visitors, the immediate effect is local: fewer available Brussels listings and a market increasingly limited to hosts meeting regional requirements. Platform access still does not replace Brussels registration, planning, safety or tax compliance.
What it means for you
Brussels hosts should verify their tourist-accommodation registration, planning position, safety compliance and tourist-tax obligations rather than assume an Airbnb listing is sufficient. Owner-occupiers who rent their own home occasionally should note that the planning-certificate requirement ends on 1 January 2027; other obligations remain relevant. Prospective guests may find fewer listings and should book earlier when visiting during busy periods. Residents considering a conventional lease should not assume the 1,421-listing reduction equals 1,421 homes returning to the long-term market, because the available figures do not track what happened to each withdrawn listing.
Opposing perspectives
- Brussels housing and planning authorities
Regional and municipal authorities argue that intensive tourist letting can remove homes from the residential market, particularly in central neighbourhoods. They present registration, taxation and closures as necessary tools for restoring housing, protecting neighbours and ensuring that professional operators follow the same rules as licensed accommodation businesses.
- Occasional resident hosts
Residents who rent a spare room or their principal home for limited periods may regard the former planning process as disproportionate to small-scale activity. The Brussels government’s 2027 reform partly accepts this argument by removing the planning-certificate requirement for qualifying owner-occupiers while retaining registration and tax obligations.
- Hotels and licensed accommodation operators
Licensed hospitality businesses have an interest in strict enforcement because they bear planning, safety, staffing and tax costs that unregistered short-term rentals may avoid. A smaller illegal market can improve competitive parity, although it may also concentrate visitor demand in conventional accommodation.
