Zonas Tensionadas Mallorca: Does the Rent Cap Apply to You?

Rental prices on Mallorca are exploding — and yet the island does not appear on any official list of zonas tensionadas. Why that is, what the Spanish Housing Act of 2023 (Ley 12/2023) nevertheless means for you as a tenant or landlord, and which rules have applied to the rent index since 2025, are all explained in this guide. You will learn how a zona tensionada is declared in the first place, which five concrete tenant rights apply in such areas, what the new IRAV index means for rent increases, and why landlords on Mallorca must already comply with certain obligations under the Ley de Vivienda — entirely regardless of any stressed-market declaration.

What is a Zona Tensionada — and how is it declared?

A zona de mercado residencial tensionado is an area defined by the legislature in which the residential property market is so overheated that it is no longer affordable for a significant proportion of the population. The legal basis is provided by the Ley 12/2023, de 24 de mayo, por el Derecho a la Vivienda — the most comprehensive Spanish housing legislation in decades.

For an autonomous community to be able to apply to the state for a declaration, at least one of two criteria must be met according to the law:

Crucially, the initiative lies not with the state, but with the respective autonomous community. Madrid cannot impose a declaration from above — the Balearic Islands must apply for it themselves and submit it to the Ministerio de Vivienda for approval. The declaration period is initially three years and is renewable.

Note: The declaration applies to specific geographical areas — typically individual municipalities or districts, not entire islands or autonomous communities.

Mallorca 2026: No declared Zona Tensionada — but why?

Anyone searching the lists of officially declared zonas tensionadas in Spain will find Catalonia, Navarre and the Basque Country — but not a single Balearic area. This is no oversight.

The current regional government of the Balearic Islands (Govern Balear) has to date submitted no formal application for a declaration. There are political reasons for this: rent control measures find little favour with the incumbent coalition. At the same time, housing experts acknowledge that Palma and many other Mallorcan municipalities would meet both criteria of the Ley de Vivienda on a purely statistical basis — the cost of housing exceeds 30 % of median household income across large parts of the island.

What does this mean for you in practice?

This means: Mallorca is not a regulation-free zone. Many of the protections enshrined in the 2023 Housing Act take effect even without stressed-area status.

The five tenant rights in a genuine Zona Tensionada

For areas that have already been declared (and as a model for what would also apply in Mallorca should the Balearic government submit an application), the Ley de Vivienda provides for five specific protective mechanisms:

1. Rent Cap on New Lettings

In declared stressed areas, the new rent must not exceed the price set in the last valid tenancy agreement. For properties that have not been let within the past five years, the national reference index (Sistema Estatal de Referencia de Precios de Alquiler, SERPAVI) applies as the upper limit.

2. Alignment with the Previous Rent

When a property changes tenant, the rent may not, as a general rule, be increased beyond the last agreed rental price — even if some time has passed between two contracts.

3. Ban on Passing New Costs on to Tenants

In stressed areas, landlords are prohibited from passing on additional costs (e.g. service charges, IBI, buildings insurance) to the tenant if those costs were not previously included in the contract.

4. Extraordinary Extension (Prórroga Extraordinaria)

Tenants who find themselves in financial difficulty at the end of their standard tenancy (after 5 or 7 years) may apply for an extraordinary extension of up to one year in stressed areas. The landlord is generally obliged to accept this — unless they can demonstrably show that the property is required for their own use or that of a family member.

5. Protection in Cases of Vulnerability

Where a tenant in a declared stressed area is classified as being in a vulnerable situation (vulnerable), special protective measures apply — among other things, eviction proceedings may be delayed or suspended until alternatives have been arranged by social services.

Please note: These five rights do not currently apply on Mallorca at all, as no Balearic area has been officially declared. They would only come into force once a corresponding declaration has been made.

What already applies today: Ley de Vivienda & LAU on Mallorca

Even without a zona tensionada designation, the 2023 Housing Act has changed day-to-day life for landlords and tenants on Mallorca. The following rules are applicable island-wide and with immediate effect:

For long-term rentals on Mallorca, the following applies: the fundamental framework of minimum term, deposit rules, and allocation of agent fees is firmly established — it is non-negotiable.

The IRAV index: how rent increases are calculated from 2025

This is the most practically relevant change for current tenancy agreements on Mallorca. From 2025, the new IRAV (Índice de Referencia para la Actualización de los Arrendamientos de Vivienda) replaces the previous IPC as the benchmark for rent increases.

Background: The CPI rose sharply during the high-inflation years of 2022/2023, leading to exceptionally large rent increases. The IRAV is intended to ensure more moderate, stable adjustments in future.

What you need to know as a landlord or tenant:

• The IRAV is published by the INE (Instituto Nacional de Estadística).
• It applies to the annual adjustment of existing tenancy agreements — not to the initial signing.
• Without a zona tensionada declaration, it is the only legally capped pricing mechanism within an ongoing tenancy.
• The adjustment must be announced in the contract or by separate notice at least 30 days in advance.

Please note: If your tenancy agreement contains no indexation clause, the rent cannot be unilaterally increased during the current contract until further notice. Clause present but linked to the CPI? In that case, the IRAV will automatically apply from 2025 onwards — provided the contract exists after the new rules come into force. Legal advice is recommended for your specific contractual situation.

The seasonal tenancy agreement: an attempt to sidestep rent controls

A widespread phenomenon in Mallorca: landlords use the seasonal tenancy agreement (arrendamiento de temporada, LAU Art. 3) to circumvent the tenant protections of the vivienda habitual. Unlike a long-term tenancy, this type of contract is not subject to LAU residential tenancy protections — minimum term, IRAV indexation, and the obligation to charge agency fees to the landlord do not apply in the same way.

What you should know:

Please note: If you will in reality be living in the property permanently but sign a seasonal contract, this may be legally regarded as circumvention. In that case, courts may retrospectively classify the contract as a vivienda habitual — with all the consequences for the landlord. Have a solicitor check which type of contract suits your specific situation.

Which municipalities in Mallorca could potentially qualify as a Zona Tensionada?

Even without an official declaration, it is worth understanding which areas would most readily meet the formal criteria. A clear picture emerges from the available rental price and income data:

This assessment is based on the statutory criteria and the general market picture — no official designation exists, as the Balearic Islands government has not submitted an application.

Landlord obligations on Mallorca: a checklist regardless of zone status

Whether your property is located in a zona tensionada or not — as a landlord on Mallorca you need to be aware of the following obligations:

1. Lodge the fianza: The mandatory deposit (1 month's rent for residential lettings) must be lodged with the Balearic authority (IBAVI or the relevant body).
2. Word the IRAV index clause correctly: Blanket rent-increase clauses that exceed the IRAV are not permitted in existing tenancy agreements.
3. Do not pass agency costs on to the tenant: For long-term tenancy agreements, the landlord bears the estate agent's commission — this also applies in Mallorca.
4. No new cost transfers without an agreement: Costs such as IBI, community fees or insurance can only be passed on to the tenant if this is explicitly stated in the contract.
5. Cédula de habitabilidad: The property must have a valid cédula at the time of letting. Find out more in the Guide to the Cédula de Habitabilidad.
6. Don't forget national registration: Since 2025, short-term lets of under 30 days via platforms additionally require national registration with a Número de Identificación Único (NIU) — in addition to the regional ETV licence.
7. Check tax deductions: With long-term lets, you may benefit from IRPF deductions. Details in the Guide to IRPF Deductions for Landlords in the Balearen.

Most common mistakes — for tenants and landlords

Tenants' mistakes

• Signing a seasonal contract when moving in permanently: By doing so, you forfeit five years of security of tenure and IRAV protection.
• Assuming the rent cap applies automatically in Mallorca: It currently does not — because no zona tensionada has been declared.
• Paying the deposit without a receipt: Always insist on proof that the fianza has been lodged with the relevant authority.
• Accepting a rent increase above the IRAV without checking: Just because a landlord demands it does not automatically make it lawful.

Landlord mistakes

• Charging agency fees to the tenant: Prohibited since 2023 for vivienda habitual — including on Mallorca.
• Rent increases without an indexation clause in the contract: Without a corresponding clause, a unilateral increase is not permitted.
• Using a seasonal contract as a long-term tenancy: If the tenant can demonstrably show they are using the property as their primary residence, a court may recharacterise the contract.
• Failing to make use of tax deductions: As a landlord, you may be entitled to IRPF deductions on long-term lets — do not leave these on the table.

What comes next? Possible developments for Mallorca

The political landscape is fluid. Here is what you should keep an eye on:

• A change of government at Balearic level: Should a different coalition take over the Govern Balear, an application to declare zonas tensionadas for Palma and other municipalities could quickly come onto the agenda — the criteria would be arithmetically achievable.
• European pressure: Spain is under increasing EU pressure to address housing problems in a structural way. In the medium term, this could also influence Balearic policy.
• IRAV developments: The new index has been active since 2025 — its precise impact on rent increases will depend on the current INE publication at any given time. Keep a close watch on the index values.
• National tenancy register developments: The national tenancy register (Ventanilla Única Digital) has been operational since 2025. Platforms such as Airbnb and Booking.com are legally obliged to remove unregistered listings.

Anyone who owns or is looking to purchase a property on Mallorca should follow these developments closely. A declaration can significantly affect market value and letting strategy. It is also worth consulting the guide to the Ley Vivienda Balearen.

Checklist: Are you properly set up as a tenant or landlord?

For tenants on Mallorca:

• Contract type checked: vivienda habitual or temporada?
• Duration and renewal options clearly set out in the contract?
• Deposit correctly lodged and receipt obtained?
• Not paid the estate agent's fees yourself?
• Rent increase clause checked on the basis of IRAV?
• Empadronamiento applied for with a long-term tenancy agreement?

For landlords on Mallorca:

• Fianza lodged with the relevant authority?
• IRAV index clause correctly included in the contract?
• Estate agent's fees borne by yourself?
• Cédula de habitabilidad valid?
• IRPF deductions for long-term letting checked?
• For short-term rentals: NIU + ETV licence in place?

Conclusion

The zonas tensionadas with their full rent cap do not apply on Mallorca as of 2026 — no application has been submitted by the Balearic Government. Nevertheless, the Mallorcan rental market is far from a regulation-free zone: the IRAV rent index, minimum tenancy durations, the ban on charging estate agent fees to tenants, and the deposit rules under the Ley de Vivienda and the LAU apply across the island. Landlords who insist on the wrong type of contract risk having it retrospectively recharacterised by the courts — and tenants risk losing years of housing security. The political situation may change: a new regional government could submit a declaration application, and the five tenant rights contained in the Housing Act would then come into force overnight. Being well informed — now — is the best protection.
