What is a stressed residential market area (“zona tensionada”) and how do I know if my flat is in one?

Question

José Manuel Alburquerque · Accepted Answer

It is an area that the regional government declares a “zona de mercado residencial tensionado” (stressed residential market area) because housing there takes up too much of household income or its cost has risen much faster than other prices. This is allowed by the 2023 Spanish housing act and the declaration lasts three years, which can be extended. In Catalonia the Generalitat de Catalunya (the Catalan government) declares them by municipality and, following its two decisions of 16 October 2026, the list stands at 302 municipalities, including Barcelona and the main cities in its area. To find out whether your flat is in one, check whether your municipality is on that list. When an area is declared Law 12/2023 on the right to housing allows an area to be declared when one of these two situations arises: What households pay on average for their mortgage or rent, including expenses and basic utilities, exceeds 30 % of their average income. The purchase price or rent has risen over the previous five years by at least three points more than the cumulative consumer price index (CPI), the index that measures the general rise in prices, for that region. For example, if the CPI has risen by 15 % over those five years, rents must have risen by at least 18 %. Once the three years have passed, the declaration can be extended year by year as long as those conditions persist. The first ones in Catalonia date from 2024. How to find out whether your flat is in one The Generalitat's decisions of 16 October 2026 extend for one year the declaration covering 118 municipalities, including Barcelona, L'Hospitalet de Llobregat, Badalona, Terrassa, Sabadell, Girona and Tarragona. They also declare 53 new ones, such as Martorell, Sant Andreu de la Barca, Tordera or Vila-seca. With the 131 added in October 2024, the list stands at 302 municipalities. By contrast, another 22 that no longer meet the conditions are left out of the extension, including Lleida, Reus, Granollers, Figueres, Mollet del Vallès and Tortosa. The decisions are published in the “Diari Oficial de la Generalitat de Catalunya”, the Catalan official gazette. The list is also on the housing websites of the Generalitat and of the “Ministerio de Vivienda”, Spain's Ministry of Housing. If your flat is in one of the municipalities joining or leaving the list, check from what date the change applies. New ones start applying the caps when the Ministry of Housing publishes the declaration in the “Boletín Oficial del Estado”, Spain's Official State Gazette. Those leaving remain covered, in principle, until their current declaration expires, probably in March 2027, so until then the prudent course is to keep complying with the caps. What it means if it is The rent under new tenancies is capped. If the flat was let as a home in the previous five years, it cannot exceed the last rent, with the annual update provided for in that agreement. If the owner is a large-scale landlord (“gran tenedor”), it cannot exceed the reference rent index of the Ministry of Housing. In Catalonia, that index also applies to flats that have not been let during that time. In Catalonia, for the purposes of that cap, a large-scale landlord is anyone who owns five or more residential properties in the area. The advert and the tenancy agreement must state the maximum rent. The document certifying it must also be attached to the agreement. When the tenancy ends, the tenant can request an extraordinary extension, year by year and for up to three more years, which the landlord can only refuse in the cases provided for by law.
