Signing a Spanish rental agreement under the new rent-cap law

Spain's 2% Rent Cap Law (RDL 8/2026): What Landlords Need to Know

The Bottom Line

If you own a rental property in Spain, or are thinking about becoming a landlord, this is the most important change to tenancy law in over a decade. On 20 March 2026, the Spanish Council of Ministers approved Real Decreto-ley 8/2026, a decree that caps annual rent increases at 2% and grants tenants the right to mandatory contract extensions of up to two years. The decree was published in the BOE on 21 March 2026 (BOE-A-2026-6545) and is now in force.

What Does RDL 8/2026 Do?

The decree introduces two measures that apply across all of Spain - not just in declared "stressed market zones":

1. A 2% Cap on All Annual Rent Increases

From the decree's entry into force until 31 December 2027, rent increases on residential leases cannot exceed 2%.

  • If the applicable index says 4%, the maximum increase is still 2%.
  • If the index says 1.8%, then 1.8% applies (the cap is a ceiling, not a floor).
  • Applies to all landlords: individuals, companies, investment funds, and SOCIMIs.
  • Any contractual clause that tries to override this 2% limit is null and void under the decree.

This analysis is confirmed by multiple sources including BM Consulting, who published a detailed breakdown of the decree's mechanics (BM Consulting, March 2026).

2. Mandatory Two-Year Contract Extensions

Tenants whose habitual residence leases expire before 31 December 2027 can request an extraordinary extension of up to two years under the same terms as their current contract.

  • The tenant must request this in writing at least two months before the contract expires.
  • The landlord must accept unless they can prove personal need for the property (for themselves or first-degree relatives), as per Article 9.3 of the LAU.
  • The landlord cannot demand different terms or force the tenant to sign a new contract.

For a concrete example: a lease signed in March 2021 by an individual landlord would have completed its 5-year mandatory period in March 2026. If the tenant invokes RDL 8/2026, they can extend until March 2028. This scenario is described in detail by Bufet Gómez Ferré.

Why Was This Law Passed?

The decree itself states its justification: thousands of rental contracts signed during 2019 - 2021 are expiring in 2026, at the same time that asking rents across Spain have reached record highs. The government argues that without intervention, the combined effect of mass contract renewals and soaring prices would make housing unaffordable for many families.

The decree also explicitly cites the Iran conflict (la guerra de Irán) as a factor that threatens to push energy prices higher, which would drive inflation and make the existing IRAE reference index unsuitable as a benchmark.

Spain's Rental Market in 2026 - The Data

This law did not emerge in a vacuum. Here is what the data shows:

  • According to Idealista data, rental prices in Spain had risen ~11.5% in 2024, reaching an all-time high of approximately €13.50/m² per month (Idealista).
  • In Barcelona, rents average around €24.0/m², or roughly €1,920 per month for a typical apartment (Idealista, March 2026).
  • Property sale prices in Spain reached a new record of €2,673/m² in early 2026, up 17.7% year-on-year, according to Idealista data (Euro Weekly News, March 2026).
  • The INE's new reference index (IRAE) stood at approximately 2.3% in January 2026 (Idealista, March 2026).
  • A two-bedroom apartment in Madrid averages around €1,700 per month, while in Barcelona it is approximately €2,050 per month (Investropa, 2026).

Tax Incentives for Landlords

Prime Minister Pedro Sánchez announced accompanying tax incentives in January 2026, as reported by Reuters:

  • 100% personal income tax rebate for landlords who renew leases without raising rent.
  • 50% rebate for landlords who sign new contracts within the regulated price band.

What This Means for Landlords

  • Rent increases are capped at 2% through the end of 2027. If inflation runs higher, your real rental income will decline.
  • You cannot recover the property from a tenant who invokes the extraordinary extension, unless you need it for personal use.
  • Tax incentives exist if you choose not to increase rent at all.
  • The 2% cap applies to all landlords equally - there is no distinction between "small" and "large" holders for this measure.

What Comes Next?

According to legal analysis from SEPIN, the decree's effects are likely to be "very substantial" - potentially exceeding what even its own sponsors anticipated.

Key dates:

  • Now in force: The 2% cap and extension rights are already active.
  • 31 December 2027: The measures expire unless extended.
  • Congressional ratification: The decree needs parliamentary validation to remain in force permanently.

What this actually means for rents on the Costa del Sol in 2026

If you deal with long-term rentals on the Costa del Sol, expect a legal limit on how much a contracted rent can be raised at renewal - but market asking rents in coastal towns remain above many interior and smaller-city averages. To see current local asking rents and recent trends, check nationwide portals such as Idealista and Fotocasa, the INE rental statistics, and Málaga-provincial or municipal reports. Compare by municipality and by price per square metre rather than by national headlines to get a realistic expectation for Marbella, Estepona, Fuengirola and nearby towns.

Short-term and tourist rentals are treated differently. Properties let as tourist accommodation under Andalusian and municipal tourism rules are generally not covered by the same tenancy measures that apply to habitual-residence leases. Owners who let through short-stay platforms should confirm the classification of their listing - converting a habitual long-term tenancy into declared tourist use involves separate regional and local licensing rules.

Practical steps for landlords and tenants on the Costa del Sol - check the exact indexation clause in the lease, calculate the contracted percentage change for the relevant period, then apply the legally permitted ceiling; always notify the other party in writing according to the contract timing; keep evidence of communication. For reliable local benchmarks and recent asking-price snapshots use the portals named above plus local estate agents' market notes, and consult a Spanish property lawyer if a renewal or eviction is disputed.

FAQ

Are holiday lets on the Costa del Sol affected?

Generally no - regulated tourist accommodation is governed by tourism and municipal licensing rules rather than the tenancy measures that apply to habitual-residence leases. Check your registration and local ordinances if you mix short-term and long-term use.

Where can I find the average rent for my town?

Use Idealista and Fotocasa to filter by province, town and neighbourhood; consult INE statistics for wider official trends; and look for Málaga-provincial or municipal bulletins and reports from local agents for hyper-local context.

What if a tenant or landlord disputes a proposed change?

If there is a dispute, negotiate in writing first and get local legal advice. Courts and tribunals will only enforce changes that comply with the tenancy rules and the contract, so documentation and timely notices are essential.
