If you are renting a flat or you are a landlord with tenants, you have probably wondered at some point whether the annual rent increase is a right, an obligation, or simply an option. The short answer is that the landlord may update the rent each year, but is not obliged to do so. Furthermore, they can only do so if certain conditions are met. We explain it all clearly below.
The law regulates rent reviews, but does not impose them
The Urban Leases Act (LAU) recognises the landlord's right to review the rent once a year, specifically upon the completion of each annual period of the tenancy. However, this right is neither automatic nor unconditional. Article 18.1 of the LAU makes it clear that any review may only take place on the terms previously agreed by both parties — that is, whatever is set out in the signed tenancy agreement.
In other words: if the contract does not include a rent review clause, the landlord cannot raise the rent even though the law would theoretically permit it. The contract is the document that governs the relationship between landlord and tenant, and neither party can disregard what has been agreed within it.
What must the contract include for a rent increase to be valid?
For the landlord to be able to review the rent annually, the contract must expressly provide for this possibility and, as a rule, specify the index or criterion to be used to calculate the increase. Although there is no single standard template, it is most common in tenancy agreements in Barcelona, the Maresme, or the Costa Brava to refer to an official indicator linked to the evolution of prices.
If you are a landlord and wish to include such a clause, or if you are a tenant and are unsure exactly what your contract states, the most advisable course of action is to review it carefully before accepting or rejecting any proposed rent review.
How much can the rent be increased?
The LAU also sets limits on the amount by which the rent may be increased. These limits have varied in recent years as a result of exceptional measures approved by the Government, so it is important to check what the applicable cap is at the time the review takes place. In any case, the landlord cannot raise the rent by whatever amount they choose: the increase is capped by whatever the current regulations stipulate.
- The review may only be applied once a year, upon the completion of each annual period of the tenancy.
- It must be expressly provided for in the tenancy agreement.
- The increase cannot exceed the limit set by the legislation in force at that time.
- If the contract does not include a rent review clause, the rent remains fixed for the entire duration of the tenancy.
- Both the landlord and the tenant may request the review if the contract provides for it.
The landlord is not obliged to raise the rent
This point deserves its own paragraph, as it causes considerable confusion. The fact that the law permits an annual review does not mean the landlord must apply one. Many landlords choose not to review the rent — particularly if they have reliable tenants or wish to avoid friction — and this is perfectly lawful. A rent review is a right, not a requirement.
Equally, if the landlord decides not to apply an increase in one year, this does not prevent them from doing so the following year, provided the contract allows for it and the legal deadlines and limits are observed.
