The implementation of the new Housing Law in Spain has coincided with a sharp decline in new rental contracts in Catalonia, a trend that worries investors, owners, and tenants. Official data from the first quarter of 2025 shows that in Catalonia, almost 20% fewer contracts were signed than the previous year (27,716 contracts compared to 34,503), the lowest level since 2010. In the 15 most populated Catalan cities, the accumulated drop reaches 21.1% year-on-year, and in key areas like Barcelona, the contraction is around 22.5%. Some municipalities in the metropolitan area have experienced declines close to 30% in new signings (for example, L’Hospitalet de Llobregat with -31.2% and Terrassa with -29.4%). This scenario contrasts with the initial optimism of the authorities, who had attributed positive effects of the Housing Law on price moderation and an increase in contracts, but whose “political narratives” are being contradicted by the statistics.
What has caused the new rental law in Catalonia? Following the implementation of the 2023 Housing Law and the price caps in stressed areas, Catalonia has recorded a significant drop in new rental contracts, especially in Barcelona and its metropolitan area. Although prices have slightly moderated in some cases, the market shows less turnover and lower available supply, which has increased competition among tenants.
Legislative context: the 2023 Housing Law and rental regulation
The Law 12/2023, for the Right to Housing, approved in May 2023, introduced measures for regulating rental prices in areas declared “stressed residential market.” Catalonia has been a pioneer in fully applying this regulation, declaring 140 municipalities as stressed areas by the end of 2023 to curb rent increases. In these areas, caps on rents for new contracts were imposed, differentiating between large and small landlords:
- Large holder: Person or company with more than 10 properties owned (in Catalonia, the Generalitat reduced the threshold to 5 properties to be considered a large holder). These large landlords face additional restrictions in stressed areas.
- Small holder: Private owner with fewer than 10 properties (or less than 1,500 m²) for residential rental.
How does the law limit rentals in pressured areas? For new contracts in these areas, the rent cannot exceed the rent of the previous contract (valid in the last 5 years) except for adjustments of the annual index. Furthermore, if the owner is a large holder, the price cannot exceed the Rental Price Reference Index published by the Ministry. Small holders must also comply with that index if the property has not been rented in the last five years. Outside of pressured areas, rent continues to be freely negotiated, although annual updates of rents are legally limited (2% in 2023, 3% in 2024 and then the new IRAV index) for all contracts following the Housing Law.
One of the most relevant points of this regulation is the gradual replacement of the CPI as a direct reference. Starting in 2025, the IRAV (Reference Index for the Update of Housing Leases) comes into play, designed to limit sharp increases in existing contracts. This change affects both owners and tenants, as it conditions the annual rent reviews even outside of pressured areas.
In practice, the new rental law in Catalonia not only affects the initial price of the contract but also the update margin, reducing market flexibility and altering the investment strategy in housing intended for leasing.
The spirit of the law is to protect tenants and curb exorbitant increases, in a context of strong rental price hikes in Spain. However, since its approval, there have been criticisms from the real estate sector and analysts warning of negative side effects. Catalonia, which had previous experience with autonomous rental controls (Catalan Law 11/2020, later annulled), became the main laboratory for the state Housing Law. Now, a year after its entry into force, data from the Catalan market allows for a first analysis of its real impact.
Impact on the real estate market in Barcelona and Catalonia in 2025
The official data from the Generalitat (Incasòl) shows a contraction of the rental supply in Catalonia following the implementation of the law. In the first quarter of 2025, 27,716 new lease contracts were signed throughout Catalonia, almost 6,800 contracts less than in the same period of the previous year. This year-on-year drop of 19.7% contrasts with claims that the intervention would improve access to housing. In fact, the number of new rentals is the lowest in 15 years (excluding the pandemic halt in 2020).
Barcelona capital, the largest market, recorded only 7,615 contracts in the first quarter of 2025, about 2,210 fewer than a year earlier. That is to say, Barcelona is experiencing a reduction of approximately 22-23% year-on-year in new rental operations. Other major cities also show significant annual declines in the number of signed contracts, for example: L’Hospitalet (-408 contracts, -31.2%), Terrassa (-300 contracts, -29.4%), Sabadell (-183, ~-25%), Santa Coloma de Gramenet (-127, ~-26%), Sant Cugat del Vallès (-103, ~-25%). Even cities with more moderate declines (Girona, Tarragona, Lleida, etc.) show declines of between 9% and 19% in new rentals. Overall, the 15 largest municipalities in Catalonia account for about 4,000 fewer contracts than a year ago (an aggregated drop of ~21%).
This effect is especially visible in the new rental law Barcelona, where the demand for rentals is structurally very high due to factors such as employment, tourism, student mobility, and the arrival of international profiles. In a context where the rental housing stock is limited, any reduction in supply quickly translates into greater pressure on the market.
This sharp reduction in new contracts implies that there are fewer apartments available for rent and less turnover of homes. Paradoxically, the total number of active contracts may have remained the same or even increased slightly, because many tenants choose to stay longer in their current homes to take advantage of the limitation on rent increases and avoid difficulties in finding a new home. In fact, Catalan authorities have highlighted that “many contracts are extending their duration, reducing the number of terminated contracts” as a positive reading of the situation. However, this is a double-edged sword: if tenants do not move, the rental supply available for new tenants decreases, intensifying competition for each home.
The demand, far from decreasing, has intensified. The combination of fewer apartments offered and a large number of rental seekers has caused cities like Barcelona to have dozens of candidates for each home. According to data from idealista, Barcelona is currently the most competitive market in Spain, with 61 families on average bidding for each rental listing. This figure doubles the national average and has grown by almost 100% in two years (before the law, at the beginning of 2023, demand in Barcelona was half). Other Catalan capitals also face high pressure: in Lleida there are about 66 interested parties per apartment, in Girona 37, etc. This strong unmet demand exerts upward pressure on prices, despite the controls.
Effect on rental prices: have they really decreased?
One of the main objectives of the Housing Law was to moderate rental prices. Data indicates that, on average, offered rents have been contained or slightly reduced in Catalonia, although with important nuances. In the first quarter of 2025, the average rent for new contracts was €828 per month, compared to €869 a year earlier, representing a year-on-year decrease of 4.7%. It also decreased compared to the previous quarter (when it averaged €840).
However, this drop in rents is not uniform across all areas nor does it imply that renting is cheaper for everyone. In large cities like Barcelona or L’Hospitalet, average rents are indeed somewhat lower than last year (thanks to the applied caps), but in others like Girona, Cornellà, Sant Boi or Mataró, the average price rose slightly compared to 2024. That is to say, while the caps have managed to curb or reduce prices in some highly pressured areas, in other locations rents continue to rise (possibly due to scarce supply and demand pushing prices up within the legal margin). Furthermore, the average drop of 4-5% is well below the accumulated inflation, suggesting that in real terms the effort to pay rent has not improved substantially for new tenants.
In summary, the Housing Law has had some limited success in cooling prices but at the cost of a marked cooling of the available supply. Rents in new contracts have moderately decreased on average, but the cost of obtaining an apartment may have even become greater in a broad sense: now more time is invested in the search, competing with more applicants and, at times, accepting more demanding conditions (guarantees, non-payment insurance, etc.) that landlords impose due to such demand.
Causes of the drop in new contracts: what is happening?
Several factors explain this strong contraction in the signing of new leases in Catalonia since March 2024 (when price limits were effectively applied in pressured areas):
- Withdrawal of offers by owners: Many owners have chosen not to put their homes on the market or to withdraw them in light of the prospect of lower returns and greater regulation. The law limits how much they can charge and makes rent updates difficult, which particularly discourages investors and large holders. According to a study, price intervention can create “distortions in the behavior of economic agents” and prevent supply and demand from adjusting properly, reducing the number of available homes. In fact, in two years, 17% of the rental supply has been lost nationally (about 120,000 fewer homes for rent) since regulation was proposed, a sign that many owners have decided to sell or allocate their apartments to other uses.
- Search for more lucrative alternatives: In light of the caps, some owners are redirecting their homes to tourist or seasonal rentals, sectors that are less regulated and potentially more profitable. In Catalonia, there has been a rise in month-to-month rentals to expatriates, students, or vacation rentals, modalities that escape the limitations of the Housing Law. This reduces the supply of regular residential rentals. The Catalan government has even warned that many landlords “are moving to seasonal rentals” and is studying ways to regulate these short-term leases as well, reflecting how owners are seeking loopholes outside the traditional market.
- “Staying in the apartment” effect: Current tenants tend to stay longer in their homes instead of moving, given that the law limits the annual increase (2-3%) within existing contracts, but, on the other hand, the prices of a new contract could be higher than what they are currently paying. As turnover decreases, contract cancellations fall and therefore also new contracts signed. This lower residential mobility translates into fewer opportunities for new tenants to access a rented home.
- Legal insecurity and perceived overprotection of the tenant: Another factor cited by owners and investors is the growing difficulties in recovering the property in case of non-payment or squatting, due to legal changes. The Housing Law tightened eviction processes in situations of social vulnerability, which while protecting disadvantaged groups, worries landlords. Some critical voices claim that “populist” measures that hinder evictions even of illegal occupants have created a sense of legal insecurity that discourages owners from renting. This climate of fear of not being able to easily recover the property leads many to think twice before renting.
- Economic and financial context: Although to a lesser extent, general factors such as the rise in interest rates and inflation can have an impact. With more expensive mortgages, some small property owners are selling apartments they had for rent to reduce debts, or are looking to achieve high sale prices taking advantage of the fact that buying and selling remains active. On the demand side, high purchase prices push more people towards renting, increasing pressure on an already tense rental market. Thus, a structural increase in demand (more people who cannot or do not want to buy) combines with a decrease in supply – the perfect recipe for an imbalance.
As a result, many property owners are rethinking their strategy: some choose to sell, others seek alternative modalities such as temporary rentals or room rentals, and others simply withdraw the property from the market. This reaction explains why the 2023 rental law in Catalonia may lead to a rapid decline in signed contracts even if the number of occupied homes does not immediately decrease.
Consequences for the different actors in the real estate market
For real estate investors: The current landscape raises doubts about the profitability of investing in housing for rent in regulated areas. With price limits and the threat of further interventions, the perception of regulatory risk increases. Many investors will demand higher returns to compensate for that uncertainty, which could slow down new purchases intended for rent in Catalonia. Some may shift their capital to other communities or sectors (for example, tourist housing, commercial properties, garages) with fewer restrictions. However, more institutional or long-term investors might see an opportunity: if prices stabilize and competition from new landlords decreases, those who already own a portfolio of rental apartments could benefit from a dominant position in a market with very high demand and low supply. In any case, the rules of the game have changed, and investment in the real estate market in Barcelona and other tense areas now requires a more careful analysis of current regulations and possible future reforms.
For landlord owners: Small landlords find themselves at a crossroads. On one hand, the law limits their rental income and complicates raising rent even to cover inflation, but on the other hand the overwhelming demand guarantees them tenants (and they can easily choose solvent profiles given the great competition for apartments). Many individual landlords feel that they have lost control over their property: they cannot freely set the price or update it according to the market, and they fear being tied to long contracts with rents below market. This has led some to sell their homes (taking advantage of the fact that sale prices remain relatively high) or to try to find loopholes – for example, 11-month seasonal contracts instead of stable 5-year rentals, or renting out individual rooms. Large holders (socimis, funds, property companies) have openly expressed their dissatisfaction and some have halted investment projects in affordable housing, claiming that the current framework does not guarantee them an adequate return. For landlords who continue in the market, the consequence is that they usually exercise extreme caution in tenant selection (stable income, guarantees, etc.) and may reduce investment in maintenance of the homes since they see no incentives to improve an asset whose performance is capped.
For tenants: This group is the one the law intended to benefit, but they face bittersweet effects. Existing tenants with previous contracts have been protected by the regulation: their rent updates have remained at very low levels (maximum 2% or 3% annually) and, if they live in a pressured area, upon renewal they could even negotiate decreases or maintenance of rent according to the new index. However, for new tenants or those looking for an apartment, the situation is very complicated. The scarce supply and extremely high demand mean that finding a rental becomes a daunting task: there is more competition, one needs to hurry, and often accept strict conditions. Although the advertised prices are capped, in practice many applicants might be willing to pay extras (for example, offering several months in advance) or settle for lower quality apartments, due to the lack of alternatives. Practices such as asking for several months of deposit or covert “donations,” despite being illegal, have even resurfaced due to the power imbalance in favor of the landlord. For the most vulnerable tenants, the reduced supply means fewer opportunities to access decent housing; the law protects them from abusive increases, yes, but it doesn’t help much if there are not enough available homes for rent. In summary, tenants maintain stability if they already have a contract, but those who need to move or become independent face a more hostile market in 2025 than in previous years, even with rent regulation.
Outlook and conclusions
One year after its implementation in Catalonia, the Spanish Housing Law shows mixed results. It has managed to slightly moderate rental prices in some areas, but at the cost of contracting the market: fewer new contracts, dwindling supply, and an increase in tension between supply and demand. The impact of the Housing Law in 2025 in Catalonia serves as a warning for other regions planning to declare tense areas. In fact, communities like Navarra and the Basque Country have recently followed Catalonia’s lead to limit rents, which could replicate this situation if not accompanied by further measures.
Industry experts advocate for comprehensive solutions: increasing the supply of affordable housing (incentivizing construction and rehabilitation for rental, public-private collaborations), tax incentives for owners who rent at reasonable prices, balanced legal security, and support for vulnerable groups from the public sector without placing all the burden on private landlords. Some even propose revising the Housing Law because “it has not achieved the intended objectives” and needs adjustments to rebalance the market. The goal is to find a middle ground where owners have reasons to offer their apartments for rent and tenants can access housing without facing disproportionate increases.
For investors, owners, and tenants in Barcelona and the rest of Catalonia, 2025 is proving to be a year of uncertainty and change. The 20-30% drop in new rental contracts reflects a contracting market, but also indicates a possible opportunity for reform. If supply can be boosted (for example, with incentives or freeing up land for rental) and some price containment is maintained, the market could stabilize. Otherwise, if the trend persists, we could see a deeper rental crisis: with high prices, low stock, and a portion of demand excluded. In any case, all actors will need to closely monitor the regulatory and real estate market developments in Catalonia. The balance between the right to affordable housing and the attractiveness of the rental market for owners will be key to the immediate future of renting in Catalonia 2025 and in the coming years.
Frequently Asked Questions about the New Rental Law in Catalonia
In short, the new rental law in Catalonia is transforming the residential leasing market, especially in places like Barcelona. The debate will remain open in the coming months, as the balance between price control, legal security, and increased supply will be decisive for the future of renting in Catalonia.
What is a stressed area according to the Housing Law?
It is a municipality or area where the cost of housing (rent or mortgage) exceeds certain limits in relation to the average income, or where prices have risen significantly. In these areas, rent caps apply to new contracts.
Does the rental law in Catalonia 2023 affect all contracts?
No. It mainly affects new contracts signed in stressed areas and the way to update rents in existing contracts through limited indices (such as the IRAV).
What happens if I am a small landlord in Barcelona?
If your property is in a stressed area, in general, you must respect the price of the previous contract and the limitations of the state index when applicable. This reduces the pricing margin and makes many landlords prioritize tenants with maximum solvency.
Have rents really decreased in Catalonia?
In some municipalities, a moderation of average rents in new contracts is observed, but at the same time, there is less available supply and much more competition, which complicates real access to housing.
Why are there fewer rental contracts in Barcelona?
Mainly due to the withdrawal of supply, lower tenant turnover, and a shift towards temporary or tourist rentals. This has reduced the number of properties available for regular rental.
