Posted in: Civil Law, Deeds Issues


rental increases

The rental market in Spain has changed significantly in recent years. Landlords and tenants cannot assume things work as they used to. New government measures were introduced to control rising rents and provide greater protection for tenants. As a result, both landlords and tenants are often uncertain about when rent can legally be increased.

At Molina Solicitors, we regularly advise both landlords and tenants over rent increases. In many cases, landlords demand an increase that is not legally permitted.

This article explains when a landlord can legally increase rent in Spain and how a tenant can defend themselves if a landlord demands a higher rent.

The Legal Framework: The Urban Leases Act

Residential rentals in Spain are governed by the Urban Leases Act (Ley de Arrendamientos Urbanos – LAU). Together with more recent housing legislation introduced by the Spanish government.

Rent increases are strictly regulated. A landlord cannot increase the rent whenever they wish. The rent can only be increased if:

the rental contract contains a rent review clause, and

the increase follows the legal limits established by law.

If the contract does not contain a clause allowing annual rent updates, the landlord cannot increase the rent during the contract period.

Most residential rental contracts by law grant tenants a minimum duration of five years. During which the tenant has the right to remain in the property if their main home and paying. Even if the contract states 11 months as they used to.

Limits on Rent Increases in Recent Years

Because of high inflation, the Spanish government introduced temporary limits on rent increases.

The recent limits have been:

2022–2023: maximum rent increase of 2%

2024: maximum rent increase of 3%

2025 onwards: rent increases must follow the IRAV (Indice de Referencia de Arrendamientos de Vivienda) published monthly by Spain’s National Statistics Institute (INE).

The IRAV replaces CPI for many contracts and acts as the maximum permitted increase.

The New Rent Update Index (2025 Onwards)

If a rental contract allows annual updates, the landlord must apply the official index, and the increase cannot exceed the value published by the government.

When a Landlord Can Increase the Rent

A landlord may legally increase rent in the following situations:

1. Annual rent review

If the contract includes a clause allowing annual rent updates, the landlord may increase the rent once per year in accordance with the legal index.

2. At the end of the contract

Once the minimum legal duration of the contract expires, the landlord may propose a new rental price when negotiating a new contract.

3. After certain property improvements

In limited circumstances, rent may increase if the landlord has carried out substantial improvement works to the property. However, strict legal conditions apply.

Illegal Rent Increases: Common Problems

Many disputes arise because landlords misunderstand the law or attempt to increase rent improperly.  This is why it is so important that contracts are drafted by lawyers; it can save a great deal of money in the long run.

Common situations include:

  • Increasing rent without a rent review clause in the contract
  • Increasing rent by more than the legal limit
  • Attempting to increase rent before the annual review date
  • Pressuring the tenant to sign a new contract with higher rent before the minimum legal period expires

In these cases, the tenant is usually entitled to refuse the increase.

How Tenants Can Defend a Rent Increase?

Tenants who receive a demand for higher rent should not assume it is legally valid.

There are several steps they can take.

The first step is to check whether the contract includes a valid clause allowing annual rent updates.

Without this clause, the rent normally cannot be increased during the contract period.

Even if the contract allows rent updates, the increase must respect the legal limits or official index.

Tenants may ask the landlord to confirm:

  • the legal basis for the increase
  • the index applied
  • how the increase has been calculated

If the landlord insists on an unlawful increase or threatens eviction, it is advisable to obtain legal advice as soon as possible.

In many cases, a formal legal response is sufficient to resolve the dispute.
