The BOE of 21 March 2026 publishes **Real Decreto-ley 8/2026, of 20 March**, on rental market measures in response to the economic and social consequences of the Iran war. It is a brief regulation — two articles — but with high impact on the residential market.
Context
The Government justifies the measure on the convergence of two factors: the structural housing crisis and the risk that inflation imported by the energy crisis will feed through into rental prices. The ECB anticipates a significant inflationary impact from rising energy prices. Thousands of rental contracts expire in 2026, and many Autonomous Communities have not declared stressed residential market zones under Ley 12/2023.
The stated objective is to ensure that the combined burden of rent and basic utilities does not exceed 30% of average household income.
Article 1: Extraordinary extension of contracts
Scope
Habitual residence lease agreements governed by Ley 29/1994 (LAU) whose mandatory extension periods expire before 31 December 2027.
Content
At the tenant’s request, the contract is extended by additional annual periods up to a maximum of 2 years, maintaining the existing contractual terms and conditions.
Landlord obligations
The landlord is obligated to accept the extension, except:
- When the parties reach a different agreement.
- When the landlord gives notice that they need to occupy the property under Article 9.3 of the LAU (personal use, or use by first-degree relatives or a spouse in the event of divorce).
Exception
The provision does not apply when the parties negotiate a renewal at a rent lower than that of the current contract.
Article 2: Cap on annual rent increases
Large holders (art. 3.k Ley 12/2023)
The annual rent update is capped at a maximum of 2%, whether an agreement between the parties exists or not.
All other landlords
- Where an agreement exists: the agreed increase applies, subject to a 2% ceiling.
- Where no agreement exists: the increase is limited to 2% by default.
Duration
Until 31 December 2027.
Constitutional basis
The regulation is issued under Article 149.1.8 of the Constitution (exclusive state competence in civil legislation) and invokes Article 86 (extraordinary and urgent necessity), citing established constitutional case law (STC 6/1983, 29/1982, 182/1997, 137/2003, 61/2018).
Entry into force
22 March 2026 (the day after publication in the BOE).
Practical impact
For landlords
| Situation | Before RDL 8/2026 | After RDL 8/2026 |
|---|---|---|
| Contract expires in 2026 | Contract ends, free renegotiation | Tenant can force up to 2 more years |
| Annual rent update | Agreed index or CPI (no general statutory cap) | Maximum 2% per year |
| Tenant turnover | Free upon expiry | Restricted until end of 2027 |
For tenants
- Stability: tenants can remain in their home for up to 2 additional years without renegotiation.
- Predictability: rent cannot increase by more than 2% annually under any circumstances.
- Universal application: this does not depend on whether the Autonomous Community has declared a stressed zone.
For investors and SOCIMIs
- Rental income projections must be adjusted to the 2% cap.
- Portfolio turnover is reduced: existing tenants have the right to stay.
- Gross yields on residential portfolios may come under compression in a rising financing cost environment.
What you should do
If you are a landlord
- Review the expiry dates of your contracts: identify which ones fall within the scope of the RDL.
- Adjust your rent forecasts for 2026 and 2027 to the 2% maximum.
- Do not send non-renewal notices without first checking whether the tenant is entitled to the extraordinary extension.
If you are a tenant
- Check when your mandatory extension period expires. If it is before 31/12/2027, you may request the extraordinary extension.
- Do not accept increases above 2%: the RDL caps the annual update regardless of what your contract states.
If you manage an investment portfolio
- Recalculate the net yield incorporating the 2% cap and the forced extension of contracts.
- Assess the tax impact: the reduction in nominal income may affect Corporate Income Tax liability and the SOCIMI regime.
