Spain Housing Law in Alicante 2026: why your rent is still free

May in Alicante smells of late orange blossom and of the salt that climbs up the Postiguet seafront with the first real heat of the year. In the agency offices on the Rambla, in the bars on calle Castaños and on the terraces of the Explanada, the conversation is always the same: how much does it cost to rent a flat in the city. The answer in March 2026, according to Idealista's latest report, was 12.3 euros per square metre, up 10.9% on twelve months earlier. The city has touched 13.2 euros, its all-time high. And the question that follows is inevitable.

Wasn't there a new Housing Law meant to cap rents? Why do prices keep rising freely in Alicante while Barcelona publishes official indexes? The short answer is that the law exists, but its application depends on each autonomous community. The long answer is what follows.

What Law 12/2023 is and what it actually does

On 24 May 2023, the Spanish official gazette published Law 12/2023, on the right to housing. It is the first national law to directly regulate the residential rental market in Spain. Article 18 introduces a new figure: stressed residential market zones, geographical areas where, if formally declared, new rental contracts are subject to a price cap tied to an official index.

The key word is that one: if formally declared. The state law defines the framework and the tools. The actual declaration of each zone depends on the relevant autonomous government. Spain works as a mosaic, and here each piece decides on its own.

The two criteria to declare a stressed zone

Article 18 sets two requirements, and it is enough to meet just one. The first is an economic burden test: the average cost of mortgage or rent, plus basic utilities, must exceed 30% of the average household income in the zone. The second is a trend test: rental prices must have risen at least three percentage points above accumulated CPI in the last five years.

With recent market data, Alicante city and many coastal municipalities meet at least one of the two on paper. Elche, Benidorm, Torrevieja, Dénia, Calpe and half a dozen others meet them too. The technical study the Valencian regional government presented in May 2023 identified the three provincial capitals and around 80 more municipalities as candidates. Candidates. With no formal declaration, there is no cap to apply.

Catalonia did the homework: 271 municipalities capped

The contrast with neighbouring Catalonia is total. In August 2024 the Catalan government declared 140 municipalities as stressed residential market zones. On 15 April 2026 it began declaring another 131, for a total of 271. The list includes Barcelona, Badalona, Sabadell, Terrassa, L'Hospitalet, Mataró, Girona, Lleida, Tarragona, Reus, Sitges, Blanes, Figueres and almost the entire Catalan urban and coastal belt. More than seven million people live within those limits.

In those 271 municipalities, rent works differently. The new contract of any home that has not been rented in the last five years, and every contract signed by a large landlord, must respect the upper value of the State Reference System for Rental Prices, the SERPAVI, managed by the Ministry of Housing. The Catalan government has also lowered the large landlord threshold to five properties, against the ten set by the state law.

Catalonia today holds 89.1% of all capped municipalities in Spain. The rest of the country, in rental terms, remains under a free-agreement regime between the parties.

The Valencian Community, on the opposite side of the map

The current regional government, led by Carlos Mazón (PP) with parliamentary support from Vox, has chosen not to apply price regulation. Vox is in fact asking to repeal Law 12/2023 in full. The responsible department backs a strategy of new supply, liberalised land and the Plan Vive of affordable housing, with more than 200 Valencian municipalities signed up.

The PSPV, in opposition, files recurring motions to demand the declaration of stressed zones in València, Alicante, Castelló and municipalities of Camp de Morvedre, Horta Sud and Marina Alta. None has passed so far. Meanwhile, the procedure started by the previous Botànic government in 2023 remains shelved.

The only regional tool: a tax deduction

One residue of the previous political cycle does survive. Owners who let their home below the price set by the regional rent observatory can deduct up to 3,000 euros in the regional bracket of personal income tax. It is a carrot, not a stick: it incentivises voluntary restraint without forcing anyone. The Mazón government has kept the deduction. Its effect on the real yield of a buy-to-let flat is marginal, and most owners prefer to set rent at the market level.

What all this means for your rental in Alicante today

If you are about to rent out a flat in Alicante city, in Playa de San Juan, in El Campello, in Santa Pola or anywhere else in the province, you set the price. Full stop. There is no mandatory index, no cap on rises and no difference between a large landlord and a private owner regarding the rent you can ask.

The Urban Tenancies Law still rules everything else: minimum contract length (five years if you sign as an individual, seven as a company), mandatory renewal for the tenant, one-month legal deposit, CPI as the reference for raising rent in ongoing contracts. But the opening rent is free, and the renewal at the end of the term lets you renegotiate at market price.

SERPAVI: useful data, not a binding rule

Even so, it pays to look at SERPAVI before signing. The State Reference System for Rental Prices is available at serpavi.mivau.gob.es and gives you a value range adjusted to your street, size, building age and condition. Outside stressed zones the range is purely informative, but it works as an anchor in negotiation, as proof in a conversation with your tenant and as a reference if you ever need to defend a price before an agency or a bank appraisal.

And tomorrow, could things change?

Spanish politics is a moving sea. If a future Valencian legislature changed colours and reactivated the procedure paused in 2023, it could declare Alicante, Elche, Benidorm, Torrevieja, Dénia, Calpe and dozens more municipalities as stressed zones within a few months. The justifying memo was drafted, the technical data lined up, the municipalities were listed. A formal activation would apply the SERPAVI cap to large landlords and to any home not rented in the last five years across the province.

For now there is no sign of that shift. While the pink flamingos take off at dawn over the Santa Pola salt flats and the sea beats against the foot of Santa Bárbara castle, rent in Alicante remains what it has always been in the province: a conversation between two parties, with no state arbiter in the middle. If you buy today to rent out, the city's average gross yield hovers around 6.2%. Whether a cap will arrive tomorrow, nobody knows.
