Brussels Wants a Single European Test for When a City May Curb Short-Term Lets, and It Carves Your Own Home Out of It

The European Commission presents its Affordable Housing Act on Wednesday, and buried inside it is the first attempt to write a single European test for a question that has been answered differently in every member state: when is a city entitled to restrict short-term rentals?

The proposal does not ban anything. It does not create an EU-wide cap on Airbnb-style lettings, and it does not take the decision away from anybody. What it does is set out common criteria for establishing that an area is under "housing pressure", and, once that is established, the conditions under which national, regional or local authorities may adopt measures affecting short-term accommodation without falling foul of EU law.

The test, as drafted

Two things have to be shown. The first is that the area qualifies as under pressure, assessed against a common framework of indicators covering population, housing supply and housing demand. The second is causal: the authority has to demonstrate that short-term letting activity is itself contributing to pressure on supply or on prices, before restrictive measures can be adopted.

There is one carve-out written in as a safeguard, and it is the one most readers of this publication will care about. A person's main residence is excluded, and explicitly distinguished from housing used for tourist accommodation. Letting your own home while you are away is not the target; the second, third and tenth flat held permanently for visitors is.

The Commission is also careful about what restrictions can achieve. Its own position, set out in the proposal, is that limits on short-term lets do not resolve the structural causes of housing scarcity. Only quantitative caps or transitional rules are contemplated, and they are supposed to come alongside measures that actually increase supply: construction, rehabilitation and simpler licensing.

Why it matters here

Lisbon sits among the EU cities where housing costs weigh most heavily on residents, which places Portugal squarely inside the category the framework is written for. Portuguese councils already hold their own power to define containment areas for alojamento local, and several have used it. What has been missing is any settled account of where that power stops when it collides with the EU's internal market rules, which is exactly the gap a common assessment framework is meant to fill.

Dan Jørgensen, the European Commissioner responsible for housing, has spent months arguing that the growth of short-term lets has measurable effects on some urban housing markets and that a European answer is needed where that activity worsens prices or shrinks the supply available to residents. This is that answer, and it is a procedural one: housing remains a national, regional and local competence, and the proposal only builds a common yardstick for judging whether a given measure is compatible with EU law.

Nothing changes on Wednesday

Presentation is the start of the process, not the end of it. The text has to be negotiated by the member states in Council and by the European Parliament before any of it binds anyone, and housing files of this kind rarely move quickly. Owners and operators should read Wednesday as a signal of direction rather than a deadline.

The direction, though, is reasonably clear. The Commission has decided that the argument about short-term rentals is a housing argument rather than a tourism one, that main residences should be protected from it, and that any city wanting to restrict lettings will in future need evidence rather than instinct. For a country where the debate has run on instinct for most of a decade, that is the substantive change, whatever the final text says.
