Catalonia proposes pioneering law to curb speculative home buying

The Catalan Parliament has begun fast-track proceedings on a controversial law that would restrict the purchase of homes in areas with stressed housing markets, aiming to curb speculation and prioritize residential use. The proposal, championed by the Comuns party and backed by the governing PSC, ERC, and the CUP, would empower local councils in zones covering 90% of the population to ban purchases not intended as a primary residence or long-term rental at regulated prices. Large holders (with five or more properties) would be barred from buying additional homes unless for their own habitual residence; small holders could buy up to four properties for designated uses. The law also creates a new 'Housing Discipline Directorate' to enforce sanctions, which sources say will be led by Fuensanta Alcalá, a former municipal housing discipline official under Ada Colau Source: elmundoes.

Market Data and Opposition

Data from the Notarial College of Catalonia shows that only 5.7% of home sales in 2025 involved properties held for under two years, suggesting speculative flipping is limited, with companies accounting for a disproportionate 64% of such sales Source: lavanguardia. Similarly, just 13% of Barcelona home purchases in 2025 were by legal entities Source: lavanguardia. Critics—including the PP, Junts, and landlord associations—argue the law violates constitutional property rights and encroaches on state jurisdiction, and have requested a review by the Consell de Garanties Estatutàries, delaying final approval until October Source: abces; infobae.

What's Next

The law's proponents defend it as a pioneering measure to ensure housing is a right, not a commodity. Despite the delay, the leftist majority assures it will pass once the legal opinion is issued. The outcome will likely set a precedent for similar interventions across Spain.
