National registration number (NRU): annulled

Spain's national short-let registration number (NRU, RD 1312/2024) was annulled by the Supreme Court in May and June 2026. What still applies in Andalucía: the regional tourist registration and the advert rule.

The national registration number (NRU): annulled

Royal Decree 1312/2024 created Spain's single digital rental registry (the Ventanilla Unica Digital de Arrendamientos). From 2 January 2025 hosts could apply for a national registration number (NRU) through the Land Registry, and from 1 July 2025 displaying it on every advert became mandatory. In May and June 2026 the Supreme Court annulled the registration procedure and the requirement to hold that number to offer a short-term let on a platform (judgments of 19 May, 21 May and 1 June 2026, published in the BOE in June and July 2026). The numbers already issued no longer condition anything, and no new ones are needed.

The annual February declaration

The decree also required an annual informative declaration to the Land Registry every February (Article 10.4 of RD 1312/2024 and Order VAU/1560/2025); the first and only cycle ran in February 2026. Article 10 is among the provisions the Supreme Court annulled, so the filing no longer conditions your platform listings. Check the BOE before relying on any part of the decree.

The Andalucian layer

In Andalucía, Decreto 28/2016 as amended by Decreto 31/2024 still applies: registration in the Registro de Turismo de Andalucía (RTA) by declaración responsable (art. 9, as rewritten by Decreto-ley 1/2025), compliance with municipal planning rules and the minimum standards (at least 14 m² per guest place, enough bathrooms, ventilation and a way to darken bedroom and living-room windows, and cooling and heating for the months you let) remain mandatory. Every rental advert must show the registration number or code where one exists, a duty that comes from Real Decreto-ley 29/2026 (art. 20.2.c, in force since 8 October 2026; as of 26 October 2026 Congress has not yet voted on it), not from the Junta decree. Since 4 March 2025 a town hall that is preparing planning rules for tourist homes can, where it justifies the need and proportionality, suspend new licences and declarations, in the whole municipality or in specific zones or building types; exceptionally, for overriding reasons of general interest, it can do so from the start of that process, for up to three years (Decreto-ley 1/2025, art. 6.2). Since 3 April 2025 an owner starting a tourist let in a home that belongs to a community of owners needs the community’s express prior approval, by three-fifths of all the owners, who must also hold three-fifths of the shares - see the community approval law page.
