Seasonal rentals have become one of the most sensitive areas of the Spanish housing market. In 2026, the legal landscape has also changed rapidly, while Catalonia applies specific rules to seasonal and room rentals. This guide explains what a genuine seasonal rental is, when an 11-month agreement can be valid, why the temporary purpose matters, what evidence should be kept and what risks arise when a seasonal contract is used for what is actually a permanent housing need.

Guide contents

What is a seasonal rental?

A seasonal rental is a tenancy intended to meet a temporary housing need rather than the tenant’s permanent housing need. The agreed duration alone does not determine the legal nature of the agreement; the genuine purpose of the occupation is crucial.

Is an 11-month rental contract legal?

It can be. An 11-month agreement may be valid where there is a genuine temporary reason, such as a temporary work assignment, studies or a limited period while the tenant’s usual home is being renovated. Simply writing “11 months” does not automatically make a tenancy seasonal.

Key point:

The label “11 months” does not replace the genuine reason for the rental. The purpose and the tenant’s circumstances are fundamental.

The key issue: the genuine temporary reason

The right question is why the tenant needs that property only for a limited period. The reason should be specific, genuine and consistent with the circumstances. In Catalonia, documenting the purpose is particularly important for contracts entered into from 1 January 2026.

Examples of temporary grounds

Possible grounds include studies, temporary professional assignments, internships, medical treatment, renovation of the tenant’s usual home and other objectively time-limited circumstances. Each case must be assessed on its own facts.

What if the temporary reason is not genuine?

If the facts show that the property is actually being used as the tenant’s permanent home, the seasonal classification may be challenged. The risk is particularly relevant where repeated seasonal agreements are used to avoid mandatory rules applying to ordinary residential leases.

Repeated 11-month contracts

A chain of short contracts does not turn a permanent housing need into a temporary one. In Catalonia, the rules applicable from 1 January 2026 require particular attention to the purpose and evidence supporting seasonal agreements.

Seasonal rentals in Catalonia in 2026

Catalonia’s Law 11/2025 on housing and urban planning measures applies to seasonal and room-rental agreements entered into from 1 January 2026. INCASÒL states that, when depositing the security for a temporary housing lease, the document proving the purpose of the contract must be attached.

Barcelona: what else should be checked?

In Barcelona it is important to distinguish ordinary housing, seasonal rentals and tourist accommodation and to review the applicable Catalan and local rules. The label used in an advertisement or contract does not replace an analysis of the actual activity.

Seasonal rental vs tourist accommodation

Tourist accommodation is a regulated tourist activity with specific administrative requirements. A seasonal rental is intended to meet a specific temporary housing need. The two concepts should not be treated as interchangeable.

What about room rentals?

Room rentals have their own legal framework and should not automatically be used to bypass rules applying to residential or tourist accommodation. The identity of the landlord, the part of the property being rented and the purpose all matter.

Deposit and supporting documents

INCASÒL distinguishes security deposits according to the type of tenancy. For seasonal agreements of less than one year, it states that the deposit is calculated proportionally to the term on the basis of two months’ rent. For temporary housing agreements from 1 January 2026, the document proving the purpose must also be attached to the deposit procedure.

Landlord checklist

Identify the temporary reason, keep reasonable evidence, draft the purpose clearly, avoid generic wording, check deposit requirements and review Catalan and local rules. If the property is advertised online, the advertisement should also accurately reflect the nature of the accommodation.

Tenant checklist

The tenant should understand why a seasonal agreement is being offered, what evidence supports the reason, how long the property is genuinely needed, what happens at expiry and which expenses and guarantees have been agreed.

What happens when the seasonal contract ends?

The answer depends on the genuine reason and the agreement. If the temporary need has ended, the tenancy may expire. If the reason continues, the parties should check whether an extension or new agreement is legally appropriate without disguising a permanent housing need.

Common mistakes

Typical mistakes include choosing an 11-month term without a genuine reason, using “seasonal” as a label, failing to keep evidence, repeatedly renewing contracts without justification, confusing seasonal and tourist rentals and overlooking Catalan rules.

What happened to RDL 26/2026?

Royal Decree-Law 26/2026, dated 29 September, introduced a specific state framework for seasonal rentals, including a genuine temporary reason and a general 12-month rule. However, Congress rejected its validation on 2 October and those measures ceased to apply. The 12-month limit from that decree should therefore not be presented today as a current nationwide rule arising from RDL 26/2026. The Government approved new housing decree-laws on 6 October 2026, whose continuation depends on parliamentary processing.

When should a lawyer review the agreement?

Legal review is particularly useful where there are repeated contracts, a long stay, a property in Barcelona or Catalonia, substantial amounts, uncertainty about the temporary purpose or a dispute between landlord and tenant.

Quick checklist before signing

  • Is there a specific temporary reason?
  • Can it be supported with documents?
  • Does the actual use match the contract?
  • Have Catalan rules been checked where applicable?
  • Are the deposit and expenses correctly agreed?
  • Does the advertisement accurately describe the legal nature of the rental?

Frequently asked questions

Is an 11-month rental agreement legal in Spain?

It can be, provided there is a genuine temporary housing reason. The 11-month duration alone does not make the agreement seasonal.

What can justify a seasonal rental?

Depending on the facts, studies, temporary work assignments, internships, medical treatment or a temporary situation involving the tenant’s usual home may qualify.

Can landlords repeatedly use 11-month contracts?

Repeated contracts should not be used to disguise a permanent housing need. The actual circumstances and applicable regional rules matter.

Are there specific seasonal-rental rules in Catalonia?

Yes. Catalonia has specific rules affecting seasonal and room-rental agreements from 1 January 2026.

Is a seasonal rental the same as an Airbnb rental?

No. Tourist accommodation is subject to a specific administrative regime, while a seasonal rental is based on a temporary housing need.
