EU Regulation 2024/1028 reaches full application on Wednesday 20 May 2026, requiring every short-term rental (STR) platform to transmit monthly listing data into a national Single Digital Entry Point (SDEP) for forwarding to municipal authorities. Each transmission carries the property address, the host registration number, the listing web address, the nights rented and the guests per night. Five Mediterranean members operate live SDEPs on the deadline: Spain, France, Italy, Greece and Portugal. Germany has not transposed the underlying rules at federal level; the Netherlands left its portal mid-build despite an eighteen-month transposition runway.12
Madrid's earlier Airbnb enforcement sets the template the new architecture inherits. Spain's Royal Decree 1312/2024 has been in force since 2 July 2025, which is what allowed the Spanish Ministry of Consumer Affairs to land its €64 million fine on the platform under listing-accuracy law rather than a cross-border digital-service argument. The same Mediterranean coalition that built domestic registration frameworks a decade before Brussels caught up is now the only group able to operate the SDEP from day one. Spain's €7bn Plan Estatal de Vivienda 2026-2030 explicitly names the regulation as the demand-side companion to its supply-side spend, locking the Madrid model into a multi-year housing strategy.
What 20 May activates is data plumbing rather than new doctrine. Once SDEPs run, every member state can see for the first time which platform listings sit inside which postcode and whether they hold a registration number. In jurisdictions whose national listings data is already centralised, enforcement begins; where the portal does not yet exist, listings continue to operate inside a vacuum no member state can close in twelve days. Berlin and Amsterdam sit inside that vacuum on 20 May, with no federal SDEP behind either listing. The platforms write their compliance playbook to the Mediterranean specification because that is the only specification with live infrastructure to write against.3
The European Commission has not formally rated readiness, and the Code Red / Code Green classification rests on industry analysis. The factual claim the evidence supports is narrower: the rules arrive with an enforcement geometry that does not match their political geometry. The first Commission compliance report after 20 May will tell the reader whether Brussels treats the northern gap as transition or as breach.
