What does EU Regulation 2024/1028 require Airbnb to do?

From 20 May 2026, Airbnb must share monthly data on host activity — nights rented, guest counts, property addresses — with national Single Digital Entry Points across the EU. Hosts must also display valid registration numbers.Source: EU Regulation 2024/1028

Is Airbnb still allowed in Mexico City?

Yes. Mexico City enacted a 180-day annual cap on short-term rentals in October 2024, but it has been suspended in practice ahead of the 2026 FIFA World Cup after Airbnb filed an injunction and hosts lobbied for a tournament-window exemption.Source: Lowdown nomads-and-communities briefing

Background

Airbnb is under coordinated regulatory pressure across Europe. Spain's Ministry of Consumer Affairs imposed a €64 million fine, the largest STR enforcement action in EU history, and the High Court of Justice of Madrid refused to suspend it on 23 March 2026. Airbnb filed a reconsideration motion in late April 2026. On 21 May 2026, Spain's Tribunal Supremo handed down judgment STS 620/2026, partially annulling Royal Decree 1312/2024 by voiding the mandatory national Unique Registration Number on constitutional competence grounds, giving Airbnb a material new defence argument: the fine cited unlicensed listings under an instrument a higher court has now partly voided. The Ministry frames the fine as resting on listing-accuracy obligations that survive the ruling; SDEP data-transmission duties also survive; the motion outcome remains open.

Founded in San Francisco in 2008 by Brian Chesky, Joe Gebbia, and Nathan Blecharczyk, Airbnb listed on Nasdaq in December 2020 at a market capitalisation above $100 billion. The platform has more than 8 million listings across 220 countries. Spain's fine was calculated as six times the profit from listings lacking valid licence numbers or displaying incorrect host details. In Mexico City, Airbnb's injunction suspended the city's annual STR cap ahead of the 2026 FIFA World Cup. EU Regulation 2024/1028 required all 27 member-state platforms to share monthly listing data with national authorities from 20 May 2026; Airbnb publicly welcomed the requirement as a compliance differentiator.

On 20 May 2026, the application date of EU Regulation 2024/1028, Airbnb's Head of EU Government Affairs, George Mavros, was the only named senior voice publicly characterising day-one readiness, through a Euronews op-ed and a 6 May statement warning that "several Member States are not technically ready". The European Commission published no response. The platform carrying Europe's largest STR fine set the day-one compliance narrative while the regulator was silent.

On 21 May 2026, Spain's Tribunal Supremo handed down STS 620/2026, partially annulling Royal Decree 1312/2024 by voiding the mandatory national Unique Registration Number on constitutional competence grounds. The SDEP data-transmission duties survive. Airbnb's pending reconsideration motion against the €64 million fine before the High Court of Justice of Madrid gains a new competence-based defence argument: the fine cited unlicensed listings and falsified registration numbers under the same Royal Decree. The Ministry of Consumer Affairs has signalled the fine rests on listing-accuracy obligations that exist independently of the registration instrument, so the defence is a material opening rather than a settled outcome; no hearing date has been set.

In CDMX, the short-let registry opened on 22 May 2026 with a roughly 30-day window, while Airbnb's injunction against the annual nights cap remains effective. An estimated 44,000 visitors used STRs across the World Cup tournament window with no cap enforcement in place.
