Catalonia’s controversial attempt to extend rent controls to seasonal lets and room rentals is now facing a constitutional challenge, adding fresh uncertainty to an already strained rental market.
The Spanish Constitutional Court has agreed to hear a challenge brought by more than 50 MPs from the opposition People’s Party (PP) against several provisions of Catalonia’s Housing and Urban Planning Law 11/2025, which came into force in January.
The law effectively extends rent controls to most residential rental contracts in designated stressed housing areas, regardless of contract duration. Seasonal rentals for work, study or medical reasons, along with room rentals, are now subject to the same pricing restrictions as long-term residential lets, removing much of their appeal for landlords who comply with the rules. Only tourist and holiday rentals remain exempt.
The PP argues that parts of the law may exceed Catalonia’s powers, infringe areas of exclusive state competence, and potentially violate constitutional principles relating to legal certainty, data protection, retroactivity, and local government autonomy.
The legal challenge follows the publication of two independent legal reports that also raised concerns about the law’s constitutionality.
One report, by administrative law professor Joan Manuel Trayter of the University of Girona, questions the expanded powers granted to housing inspectors, including their status as agents of authority and their broad enforcement powers. The report suggests these measures may conflict with fundamental rights and legal safeguards.
A second report, prepared by housing law academics Sergio Nasarre, Héctor Simón and Gemma Caballé, argues that the legislation improperly treats seasonal rentals as ordinary residential tenancies. According to the authors, this conflicts with national legislation, which distinguishes between primary residence contracts and rentals for other purposes. They also suggest the law may interfere with property rights, freedom of enterprise, and Spain’s single market framework.
Background
The Catalan government introduced the measures to stop landlords switching properties from the long-term rental market into seasonal lets in order to avoid rent controls. Supporters argue the law is necessary to protect tenants and increase affordability.
Critics, however, warn that tighter controls are likely to further reduce rental supply without significantly lowering rents. Many landlords may instead opt to sell, withdraw properties from the market, or move towards alternative housing models such as coliving.
The Constitutional Court’s decision to hear the case does not mean the law will be struck down. However, it does ensure that one of the most ambitious and controversial housing interventions in Spain will now face judicial scrutiny.
For landlords, investors and tenants alike, the result could have significant implications for the future of the rental market in Catalonia, particularly in cities such as Barcelona where seasonal rentals have become an important source of housing for students, expatriates and temporary workers.

Home » Refund battles loom after Supreme Court ruling on Spain’s rental registry
Author: Mark Stücklin Posted on
Spanish Supreme Court (Tribunal Supremo) in Madrid
The Supreme Court may have killed Spain’s national rental registry, but a new battle is just beginning. Property owners who paid registration fees could soon be lining up to demand their money back.
The Supreme Court’s decision to strike down Spain’s national short-term rental registry may have removed one headache for property owners, but it looks set to create another. A growing dispute is emerging over whether hundreds of thousands of landlords should be refunded the fees they paid to register their properties under a system that the court has now declared unlawful.
The registry required owners offering tourist or short-term rentals to obtain a unique registration code, at a base cost of €27.05 per application, before advertising their property on major platforms. During its brief existence, more than 467,000 applications were submitted, with around 374,000 approved.
The question now is simple: if the legal basis for the registry has been annulled, should owners get their money back?
The College of Property Registrars says no. Its position is that the Supreme Court ruling does not have retroactive effect and only invalidates the registration procedure going forward. The registration codes already issued remain valid and can still be used by owners, meaning, in the registrars’ view, there is no justification for reimbursing the fees paid.
Property lawyers take a very different view
According to Alejandro Fuentes-Lojo, a property law specialist and professor of civil law cited in an article at the property portal Idealista, the court’s finding that the regulation breached both constitutional and European law means the annulment should have full retroactive effect. If the obligation to obtain the registration code was unlawful from the outset, then owners should not have been required to pay for it in the first place.
That difference of interpretation could have significant financial consequences. Even at €27 per application, the total amount collected runs into many millions of euros.
Lawyers are already discussing the possibility of individual and collective claims to recover the fees. The issue may be particularly contentious for owners whose applications were rejected after they had paid the registration charges.
The registrars, meanwhile, defend the scheme’s wider impact, arguing that it helped identify more than 100,000 properties operating without complying with all legal requirements. Critics counter that Spain already has regional rental registries and that better coordination between them would be a simpler solution than creating a new national register.
For now, the registry itself may be gone, but the legal and financial fallout appears far from over. Property owners who paid registration fees should keep an eye on developments, as the next battle may be over who ultimately picks up the bill.
