EU Short-Term Rental Cap May Lower Lisbon Rents by 2026

The summer visitor scanning Lisbon’s Alfama for a rooftop flat and the young family hunting for a T2 they can actually afford are now part of the same European storyline. Brussels is preparing to step into the fiercely local arena of short-term rentals, promising continent-wide rules that could redefine how many alojamentos locais remain holiday pads and how many revert to long-term homes. The initiative, led by Danish commissioner Dan Jørgensen, lands at a moment when Portuguese rents hover at historic highs and city halls admit they can no longer tame the market alone.

A cross-border headache reaches Brussels

Portugal’s housing squeeze is no longer viewed as a quirky southern anomaly. Across the bloc, mayors from Lisbon, Barcelona and Berlin have warned that the mushrooming of Airbnb-style listings is siphoning entire neighbourhoods away from residents. By framing the issue as a “social crisis”, Commissioner Jørgensen has opened the door for the European Commission – traditionally cautious on housing – to claim a new role. His team argues that Europe’s single market makes it impossible for one city’s rules to work if an online platform can divert listings to the next coastal hotspot overnight. The political stakes are high: Jørgensen bluntly warns that ignoring the problem fuels anti-EU populists who present Brussels as indifferent to ordinary tenants.

Inside the Berlaymont, officials describe the upcoming text as a chapter of a wider European Affordable Housing Plan slated for December. Drafts seen by diplomats hint at binding obligations rather than soft guidelines, marking the clearest sign yet that holiday lets have become a matter of EU-level governance rather than municipal housekeeping.

What exactly is on the table?

While the final wording remains under wraps, three pillars have emerged from leaks and stakeholder conversations. First, a cap on the number of nights a property may be rented to tourists in so-called pressure zones. Second, a mandatory online registry that forces hosts to display an official number on every advert, allowing councils to spot illegal listings in real time. Third, stronger powers for cities to demand platform data – something partially secured by the data-sharing regulation adopted in 2024 but not yet in force.

Crucially, Brussels wants every Member State to empower local authorities to enforce those limits. That matters for Portugal, where enforcement of the 2018 “Containment Areas” in Lisbon and Porto proved patchy once court challenges began. Under the new framework, a council unwilling to police its own rules could find itself in breach of EU law – a reversal of the old dynamic where Brussels stood on the sidelines.

Why Portuguese tenants will feel the difference

Statistics compiled this autumn by the Commission paint an uncompromising picture: Lisbon’s median rent has jumped 53 % since 2017, and short-term rentals now account for roughly 8 % of the capital’s housing stock. Analysts inside Portugal’s housing observatory estimate that returning just a quarter of those units to the long-term pool could shave €90 to €120 off a typical monthly lease. For working-class families pushed to the outskirts or beyond the Tagus, that is more than a symbolic relief.

Yet sceptics warn that tourism alone is not the whole story. Recent papers from PwC and the Nova SBE Urban Lab underline chronic under-building and a tax system that rewards speculative buying. Even so, the same studies concede that “short-lets intensify scarcity in the very districts most attractive to young professionals.” By stepping in, Brussels may provide the legal shelter municipalities need to pursue bolder measures without fearing investor lawsuits wrapped in single-market rhetoric.

Lessons from Barcelona and Berlin

Southern Europe’s most radical experiment is unfolding 1 000 km east of Lisbon. In June 2024 Barcelona pledged to scrap every tourist-apartment licence by 2028, betting that 10 000 homes will re-enter the conventional market and push rents down 8 % to 13 %. Early modelling suggests the policy could work, but the city still faces a surge in so-called seasonal leases lasting 31-364 days – a loophole Portuguese lawmakers know all too well.

Further north, Berlin’s 2016 Zweckentfremdungsverbot – the mouthful German ban on misuse of housing – shows that strict rules can survive court scrutiny if paired with steep fines and robust inspections. Since the law’s latest tweak, entire-home holiday listings have dwindled, yet property prices continue their upward creep, implying that supply constraints alone cannot reverse years of real-estate financialisation. The Commission cites these mixed outcomes as proof that a patchwork of local bans leaves plenty of grey zones for platforms to exploit.

Platforms and landlords brace for tighter screws

In public, Airbnb and Booking.com repeat that harmonised regulation will provide welcome clarity. Privately, lobbyists fear a replication of Paris-style quotas across southern sunbelt cities, a scenario that could curb lucrative summer peaks. The European Holiday Home Association, which counts thousands of Portuguese small-scale landlords, argues that blanket caps risk penalising retirees supplementing pensions with occasional rentals. It is pressing Brussels to exempt “primary residences” from the harshest measures – an idea still under discussion.

On the other flank, tenant unions from Lisbon’s Geringonça neighbourhoods to Amsterdam’s canal belt demand nothing short of a license freeze. They brandish Commission numbers showing that in 2025 more than 70 % of Lisbon’s Airbnb revenue flowed to hosts with multiple properties, undercutting the image of the casual sharer. The collision of these narratives will shape the final compromise hashed out by EU ministers this winter.

The road ahead for Portugal

Once the regulation clears the European Parliament, each country must transpose the rules – likely in late 2025 – with enforcement starting in 2026. The Portuguese government, locked in pre-budget haggling, has already signalled support. Yet it will face a choice: allow municipalities to design bespoke caps or impose a uniform national ceiling. Lisbon city officials favour the former, fearing that a one-size-fits-all approach could penalise rural areas chasing off-season visitors.
