Catalonia rental law to be reviewed by Spain’s Constitutional Court
Spain’s Constitutional Court will examine a complaint against Catalonia’s housing law, which strengthens regulation of the rental market and extends price controls to seasonal leases and room rentals. The case was initiated by more than 50 deputies from the opposition People’s Party (PP), who are challenging several provisions of the regional legislation, according to Spanish Property Insight.
Rent control for seasonal rentals in Catalonia
Catalonia’s Housing Policy and Urban Planning Law 11/2025 came into force in January 2026 and significantly expanded regulation of the rental market. The law extended rent caps to most types of residential contracts in areas classified as having housing market stress.
The new rules now also apply to seasonal rental contracts used for work, study, or medical treatment, as well as room rentals. These categories are subject to the same price restrictions as long-term leases, effectively placing them under a unified regulatory framework.
The only exception is tourist and short-term holiday rentals, which remain outside the scope of the restrictions. This preserves a more flexible regime for the segment focused on visitors to Spain.
Catalan authorities introduced the changes to curb the practice of shifting properties from the long-term rental market into seasonal leases. According to their assessment, such strategies were used to bypass rent controls and further reduce housing availability for permanent residents.
Opposition and legal opinions
The complaint to the Constitutional Court was filed by more than 50 MPs from the opposition People’s Party (PP). PP representatives argue that several provisions exceed Catalonia’s competences and encroach on areas of exclusive state jurisdiction. They also claim that some measures may conflict with constitutional principles, including legal certainty, data protection, the prohibition of retroactive legislation, and local government autonomy.
The judicial review follows two independent legal opinions that also raised doubts about the law’s constitutionality. Professor of Administrative Law at the University of Girona, Joan Manuel Trayter, criticised the expanded powers granted to housing inspectors. He questioned their status as public authority agents and the scope of their enforcement powers, arguing that such measures could conflict with fundamental rights and existing legal safeguards.
A second report, prepared by housing law specialists Sergio Nasarre, Hector Simón, and Gemma Caballé, argues that the legislation incorrectly equates seasonal rentals with standard residential leases. In their view, this contradicts national legislation, which distinguishes between primary residence leases and other rental purposes. The experts also point to potential interference with property rights, freedom of enterprise, and the principles of the single market in Spain.
Previous annulment of Catalonia’s rental law
In 2022, Spain’s Constitutional Court already struck down nine articles of Catalonia’s Law 11/2020, including provisions that froze and reduced rental prices in high-demand housing areas.
The 2020 law applied to municipalities with more than 20,000 inhabitants and introduced rent caps, with certain exemptions for landlords earning less than €2,000 per month.
That case was also triggered by a complaint from the People’s Party (PP). The ruling found that the regional government had exceeded its powers and encroached on central government competences. Following the decision, a significant part of the regulatory framework ceased to apply.
Outlook for Spain’s real estate market
Analysts at International Investment note that the court’s review does not imply automatic annulment of the law, but it does increase regulatory uncertainty in the market. The balance continues to shift between housing affordability policies and rental asset profitability. Tighter rent controls may constrain rental yields, prompting some landlords to sell properties, withdraw them from the rental market, or shift toward alternative housing models.
For both institutional and private investors, regulatory predictability is becoming a key factor. This is particularly relevant in cities such as Barcelona, where seasonal rentals are widely used by students, expatriates, and temporary workers. In recent years, Spain has steadily tightened rental regulations. In Barcelona, short-term rentals are set to be banned by 2028, while partial restrictions already exist in several other regions. Taken together, these measures reinforce a long-term trend toward tighter regulation, reduced market flexibility, and rising legal risk in real estate investment decisions.
