On 19 May 2026, the Spanish Supreme Court issued an important ruling regarding the regulations surrounding short-term and holiday rentals in Spain.
The ruling mainly clarifies which authority is responsible for managing tourist rental registrations: the Spanish State or the autonomous regions.
For owners of holiday properties, this raises several questions. Is a national registration number still mandatory? What happens with Airbnb and Booking? And which licence remains valid?
In this blog, we explain what this ruling means in practice.
The Spanish Supreme Court annuls part of the national registration system
The case concerned Royal Decree 1312/2024, through which the Spanish Government intended to introduce a centralised national register for short-term rentals.
This system would have required property owners to register their property through the Registro de la Propiedad, apply for an additional national registration number and use this number on online rental platforms.
The Generalitat Valenciana challenged these regulations before the courts, and the Spanish Supreme Court partially ruled in their favour.
No double registration through the Registro de la Propiedad
According to the Court, the Spanish State cannot impose an additional national registration procedure on top of the existing regional systems.
The judges stated that tourism and housing fall under the authority of the autonomous regions. An additional registration through the Registro de la Propiedad would, in practice, function as an extra administrative authorisation. As a result, the State would be exercising powers that belong to the autonomous regions.
The ruling also points out that European legislation seeks to avoid duplicate registration procedures. When regional registers already exist, a property cannot simply be subjected to an additional national registration system.
Which registration remains mandatory?
The regional tourist registration remains essential. For property owners, this means that the registration number issued by the relevant autonomous region continues to be the valid number required to advertise a property online.
For properties located in the Comunidad Valenciana, the registration number issued by the Comunidad Valenciana therefore remains applicable.
This number must still be clearly displayed on rental platforms such as Airbnb, Booking.com and other online channels.
Airbnb and Booking will remain under supervision
Although the mandatory national registration through the Registro de la Propiedad has been annulled, the so-called Ventanilla Única Digital will continue to exist.
This is a central digital system through which information can be exchanged between authorities and rental platforms.
Platforms such as Airbnb and Booking will remain obliged to stay connected to this system, verify registration numbers and transmit information regarding rental activity.
What does this mean for property owners?
For holiday rental property owners, this ruling mainly brings greater clarity and less administrative duplication.
Owners will no longer need to apply for an additional national registration number through the Registro de la Propiedad if they already hold the correct regional registration.
The regional tourist licence or registration therefore remains the central requirement.
Important for those investing in Spanish real estate
This ruling once again highlights the importance of regional regulations within Spain.
Anyone investing in property for holiday rentals should not only consider national legislation, but also the regulations of the autonomous region and municipality where the property is located.
These rules may vary significantly depending on the region and even the municipality.
