More than two years after the introduction of rent caps in Barcelona, tenants are paying more per square meter even as rental flats become smaller, according to data from the Generalitat and analysis of new contracts deposited with Incasòl.

The average monthly rent in Barcelona for the first quarter of 2026 was €1,137, just above the €1,136 recorded in 2023 before the cap took effect. Compared to 2019, average rents have risen by 16%, outpacing inflation amid a persistent housing shortage.

Under the national Housing Law, a rental price reference index became mandatory from 16 March 2024 in stressed market areas, including all of Barcelona. The system sets maximum and minimum rent ranges based on location, size, condition, and amenities. Compliance is required for landlords with five or more properties, and for newly rented dwellings that had been off the market for at least five years.

Despite the cap, the rental market is showing a shift in composition. The average size of newly rented apartments in Barcelona has fallen from 74 to 71 square meters since the measure began. Over the same period, the price per square meter has climbed to a record high of €16.89, up 5% since 2024 and 17% compared to pre-pandemic levels, according to Generalitat data.

Ciutat Vella and La Barceloneta See Sharp Increases

The trend is most pronounced in Ciutat Vella. While average rents in the district appear to have dropped by 5% since the cap, this coincides with a significant reduction in flat sizes. The average apartment area has shrunk from 70 to 61 square meters, a 13% decline, while the price per square meter has risen 11% to €18.41.

In La Barceloneta, rents now average €23.19 per square meter, higher than in affluent areas like Pedralbes (€20.92) and Les Tres Torres (€20.38). Since the rent cap was introduced, flat sizes in La Barceloneta have plummeted from 55 to 38 square meters, making it the second-smallest rental stock in the city.

Shifts in Sant Andreu and Other Districts

Sant Andreu, traditionally one of the more affordable districts, has seen average rents rise by 2% to €920 per month. The price per square meter has increased by 7% to €14.65, even as average flat sizes have decreased from 70 to 66 square meters.

La Trinitat Vella, a neighbourhood within Sant Andreu, has seen one of the most dramatic changes: apartment sizes have shrunk from 63 to 57 square meters, while rent has surged by 28% to €844 per month.

Sants-Montjuïc has also seen significant price growth, driven by redevelopment in La Marina del Prat Vermell and La Marina del Port. While flat sizes have remained stable, rents have increased sharply over the past two years.

High-End Areas Also Affected

Even Barcelona’s most exclusive districts are not immune. In Pedralbes, rent per square meter has grown by 8% since 2024, while apartment sizes have decreased by 6%. Tres Torres has seen a 3% increase in price per square meter and an 8% reduction in average flat size.

At first, prices go down, but then they go up again.

Òscar Gorgues, manager of the Barcelona Urban Property Chamber, warned that the initial drop in rents may not last. Speaking to ARA, he said: “At first, prices go down, but then they go up again.” He noted that monthly rents in regulated areas have increased by 3.71% compared to the same quarter last year, with Barcelona seeing a 4.61% rise over the past 12 months.

While the number of new rental contracts in Barcelona has grown by over 20,000 since the cap was introduced, tenant turnover has decreased, suggesting longer tenancies and less churn in the market.
