Rental Renewal in Spain: Rent Increase Limits and Tenant Rights

Your rental contract anniversary is coming up. Your landlord has mentioned an increase. Or maybe they haven’t said anything — and you’re wondering what happens next.

Here’s the short answer: you have more power than you think. Spanish rental law is structured to protect tenants at renewal. Your landlord can raise the rent, but only within specific legal limits, with proper notice, and using the correct index. If they get any of that wrong, you can refuse the increase entirely.

This guide explains exactly how rental renewals work in Spain in 2026 — the automatic extension rules, the new IRAV rent index, what your landlord can and can’t do, and how to handle the conversation. If you haven’t read it already, our complete guide to renting in Spain covers the fundamentals.

The Renewal Moment: What Actually Happens

When your contract reaches its annual anniversary, one of three things happens:

1. Nothing changes. If your contract has no rent update clause, your rent stays the same. Period. The landlord cannot unilaterally introduce one.
2. The rent increases by the applicable index. If your contract includes an annual update clause, the landlord can raise the rent — but only by the amount permitted under law (IRAV or CPI, depending on when you signed).
3. The contract renews automatically. Unless you give notice that you want to leave, or the landlord invokes a specific legal exception, the contract simply continues for another year.

Most expats on the Costa del Sol are in scenario 2: the contract allows annual increases, the landlord sends a notice, and you need to know whether the increase is legal.

Automatic Extensions: The 5-Year and 7-Year Rule

Under LAU Art. 9, residential rental contracts automatically extend year by year until they reach:

• 5 years — if your landlord is an individual (persona física)
• 7 years — if your landlord is a company (persona jurídica)

This applies even if your written contract says “1 year.” The 1-year term is the initial period — the law guarantees you the right to stay for up to 5 or 7 years by simply not leaving. The tenant decides whether to renew each year. The landlord cannot refuse.

After the 5/7-year mandatory period ends, a second protection kicks in under LAU Art. 10: the contract automatically renews for 3 more years (the prórroga tácita) unless one party gives proper notice:

• Landlord: must give 4 months’ notice before the end of the 5/7-year period (or any annual renewal thereafter)
• Tenant: must give 2 months’ notice

If your landlord misses the 4-month notice window, the tacit 3-year extension locks in automatically. No negotiation, no exception.

Example timeline: You signed a 1-year contract on 1 June 2022 with an individual landlord. Your mandatory period runs until 1 June 2027 (5 years). If neither party gives notice by 1 February 2027 (landlord) or 1 April 2027 (tenant), the contract renews for 3 more years — through to 1 June 2030.

The New Rent Reference Index: IRAV Explained

This is the biggest change to Spanish rental law in a decade. From 1 January 2025, the CPI (Consumer Price Index) no longer governs rent increases for newer contracts. It’s been replaced by the IRAV — the Índice de Referencia de Arrendamientos de Vivienda (Reference Index for Housing Rentals).

Who does the IRAV apply to?

All residential rental contracts signed after 26 May 2023 (when the Ley de Vivienda 12/2023 took effect). If you signed before that date and your contract references the CPI, you continue using CPI.

How is the IRAV calculated?

The INE (Spain’s national statistics office) publishes the IRAV monthly. It’s calculated as the lowest of three values:

1. The year-on-year rate of change of the CPI
2. The year-on-year rate of change of underlying (core) CPI
3. An adjusted average annual rate of change, using a dampening coefficient against expected medium-term inflation

By design, the IRAV will almost always be lower than CPI. That’s the point — it’s meant to moderate rent increases and prevent landlords from passing full inflation through to tenants.

What’s the IRAV in 2026?

Month	IRAV	CPI (comparison)
January 2025	2.20%	3.00%
February 2025	2.28%	3.00%
January 2026	2.14%	2.30%

Source: INE (ine.es). IRAV January 2026 published 13 February 2026.

Worked example

Your rent is €1,400/month. Your contract anniversary is in March 2026. The IRAV for January 2026 (the latest published figure available 2 months before your anniversary) is 2.14%.

• Maximum increase: €1,400 × 0.0214 = €29.96
• New maximum rent: €1,429.96/month

If your landlord asks for €1,500, that’s above the legal cap. You can refuse the increase above €1,429.96.

You can check the exact calculation using the government’s official calculator at mivau.gob.es.

What Your Landlord Can Legally Increase — and What They Can’t

✅ What’s allowed

• Annual IRAV/CPI increase — only if the contract includes an update clause, with 30+ days’ written notice, using the correct index
• Renegotiation at end of mandatory period — after the 5/7-year mandatory period expires, the landlord can propose new terms for the tacit 3-year renewal. You don’t have to accept them
• Increase after agreed improvements — if both parties agreed in writing to property improvements (not basic maintenance), the landlord may be entitled to an increase. This must be in the contract

❌ What’s not allowed

• Increasing rent without a contract clause — no clause, no increase. Full stop
• Increasing above the IRAV/CPI cap — the applicable index is the maximum, not a suggestion
• Increasing without 30 days’ notice — notice must be in writing, delivered before the increase takes effect. No notice = no increase
• Changing the index mid-contract — if your contract says CPI, the landlord can’t switch to a higher figure. If IRAV applies by law, they can’t use CPI instead
• Charging a “market rate” increase — during the mandatory 5/7-year period, the landlord cannot raise rent to match market rates. Only the index applies

What If You Disagree? Steps to Take

If your landlord proposes an increase that doesn’t comply with the law:

1. Check the maths. Look up the applicable IRAV or CPI figure on the INE website (ine.es). Apply it to your current rent. If the proposed increase exceeds the result, it’s above the legal cap.
2. Respond in writing. Send a letter or email (with read receipt) explaining that the proposed increase exceeds the legal maximum. Cite the specific index and rate. Keep it factual, not emotional.
3. Continue paying the legal rent. Pay the current rent, or the legally increased amount if you agree the maths are correct. Do not pay the excess. Paying the inflated amount without objection may be taken as acceptance.
4. Send a burofax if necessary. A burofax is Spain’s certified mail system — it provides legal proof of content and delivery. Available at any Correos (post office). Cost: about €25. This is the standard tool for formal legal communications in Spain.
5. Contact the OMIC. Your local Oficina Municipal de Información al Consumidor provides free advice on tenant rights. In Málaga, the OMIC can also help mediate disputes.
6. Seek legal advice. If the landlord persists, a lawyer specialising in rental law (abogado especialista en arrendamientos) can send a formal demand. Many offer an initial consultation for €50–€100.

When a Landlord Can Refuse Renewal

There are very few legal grounds for a landlord to end your tenancy during the mandatory period. These are the only valid ones:

Personal use clause (LAU Art. 9.3)

After at least 12 months, the landlord can reclaim the property for personal use or for close family (first-degree relatives: children, parents, or spouse/partner in cases of legal separation or divorce). Conditions:

• This clause must be explicitly included in the contract
• The landlord must give you 2 months’ notice
• They must actually occupy the property within 3 months
• If they don’t move in within 3 months, you have the right to return to the property OR receive compensation (choose one)

Tenant breach

Non-payment of rent, subletting without permission, damage to the property, nuisance to neighbours, or using the property for illegal activity. Even then, eviction requires a court order — self-help eviction is criminal in Spain.

End of the mandatory + tacit period

After the full 5+3 years (individual) or 7+3 years (corporate), the landlord can choose not to renew by giving 4 months’ notice. At this point, a completely new contract can be negotiated — or the landlord can ask you to leave.

Rent Control Zones (Zonas Tensionadas): Does the Costa del Sol Qualify?

The Ley de Vivienda 2023 (Law 12/2023) introduced the concept of zonas tensionadas — areas where the rental market is under “stress.” In these zones, additional protections apply:

• Tenants can request an extraordinary annual extension after the contract ends
• New contracts to new tenants are capped at the previous contract’s rent
• Large landlords (5+ properties in the zone) must use the official reference index

Does the Costa del Sol qualify? By the numbers, absolutely. Marbella leads Spain with a housing effort rate of 76% (meaning the average renter spends 76% of income on rent, per Tinsa data, February 2026). Vélez-Málaga, Fuengirola, and Málaga city all meet the technical criteria — rent exceeding 30% of household income and rising faster than CPI over 5 years.

But here’s the problem: declaring a zona tensionada is the responsibility of each autonomous community, not the national government. And the Junta de Andalucía (governed by the PP party) has refused to declare any zonas tensionadas. They’ve even challenged the national Ley de Vivienda before Spain’s Constitutional Court.

As of March 2026, only Catalonia has formally applied the zona tensionada mechanism. In Andalucía, despite the Housing Minister publicly urging the region to act, no zones have been declared. This means the additional protections — extraordinary extensions, rent caps on new contracts — do not apply on the Costa del Sol right now.

Your existing contract-level protections (IRAV caps, automatic extensions) still apply. But if you’re renting from a large landlord or signing a new contract after your current one ends, you don’t have the extra zona tensionada safeguards.

632,000 Contracts Renewing in 2026: What It Means for You

According to data from Spain’s Ministry of Social Rights (reported by Europapress, December 2025), more than 632,000 rental contracts will expire across Spain during 2026. That figure affects approximately 1.6 million people.

The ministry estimates that renewing these contracts could mean an average annual increase of €1,735 per year (roughly €145/month). In some regions, it’s far worse — in the Balearic Islands, the average increase exceeds €4,600/year.

The regions with the most expiring contracts: Madrid, Catalonia, Andalusia, and the Valencian Community — all areas with high demand and limited supply.

What does this mean practically? There will be enormous pressure on landlords and tenants simultaneously. Many landlords will attempt to push rents to market rate — particularly at the end of mandatory periods when they have more legal flexibility. Tenants who don’t know their rights may accept illegal increases simply because they fear losing their homes.

Most of that leverage comes down to what your contract actually says, which is why we put together a free Spanish rental contract checklist you can hold against your own lease before the renewal conversation.

Your best defence: know exactly which year of your mandatory period you’re in, which index applies to your contract, and what the maximum legal increase is. The sections above give you everything you need.

Your Rights If the Landlord Wants You Out

If your landlord is trying to end your tenancy — whether directly or by making unreasonable demands — here’s your legal position:

• During the mandatory period (5/7 years): The landlord can only terminate for personal use (Art. 9.3, with strict conditions), tenant breach, or mutual agreement. They cannot end the contract simply because they want a higher-paying tenant or want to sell.
• If the property is sold: Your lease transfers to the new owner (LAU Art. 14). A sale does not end your contract. You also have the right of first refusal (derecho de tanteo) under LAU Art. 25.
• Pressure or harassment: A landlord who threatens you, cuts off utilities, changes locks, or enters without permission is committing a criminal offence. Report this to the police (denuncia) and contact a lawyer immediately.
• Eviction: Even for non-payment, eviction requires a court process (procedimiento de desahucio). No landlord can legally force you out without a judicial order.

Frequently Asked Questions

My contract says CPI but I signed after May 2023 — which applies?

The IRAV. Law 12/2023 (Eleventh Additional Provision) overrides the contract clause. From 1 January 2025, the IRAV is the mandatory reference for all contracts signed after 26 May 2023, regardless of what the contract says. If your landlord insists on CPI and CPI is higher, they’re wrong.

Can my landlord refuse to renew and sign a new contract at a much higher rent?

Not during the mandatory period. During years 1–5 (individual) or 1–7 (corporate), the landlord must renew under the existing terms, with only the applicable index increase. After the mandatory period, if they give proper notice (4 months), they can propose a new contract — but you’re not obligated to accept. If no notice is given, the tacit 3-year renewal begins at existing terms.

What if I’ve been renting for more than 8 years — do I have any protections?

After the mandatory period (5/7 years) plus the tacit renewal (3 years), your total protection period has ended. At that point, either party can end the contract with proper notice. However, many long-term tenancies simply continue by mutual agreement, often with periodic increases by the applicable index. Your landlord still needs to give 4 months’ notice to end the tacit renewal.

My landlord sent me a WhatsApp saying rent is going up — is that valid notice?

Spanish law requires written notice but doesn’t specify the medium. A WhatsApp message could be considered valid notice if it clearly states the new amount, the basis for the increase, and is sent at least 30 days in advance. However, the strength of WhatsApp as legal proof is weaker than a burofax or formal letter. If you want to dispute the increase, respond in writing (email or burofax) to create a clear record.

Can my landlord increase utility charges or community fees separately from rent?

If your contract specifies that you pay utilities directly to providers, the landlord has no involvement — price changes are between you and the utility company. If community fees (gastos de comunidad) are included in your rent, the landlord cannot separately increase them outside the annual rent update. If they’re billed separately (common in some contracts), the landlord should pass on the actual amount charged by the community — no markup. Check your contract to see how each cost is structured.
