Lease Agreements Under the LAU: Landlord and Tenant Rights in Spain

The residential lease agreement is probably the legal transaction that affects the most Spanish citizens, with over 3.5 million households renting. Law 29/1994, of November 24, on Urban Leases (LAU), substantially amended by Royal Decree-Law 7/2019 and by Law 12/2023, of May 24, on the Right to Housing, constitutes the fundamental legal framework governing these relationships.

This guide comprehensively analyzes the rights and obligations of landlords and tenants, contractual duration, rent updates, deposits, and the most relevant clauses.

Current Legal Framework: The LAU After Reforms

Recent legislative evolution

The LAU has undergone substantial modifications in recent years:

LAU 1994 (original versión): minimum duration of 5 years, free rent.
2013 Reform (Law 4/2013): reduced minimum duration to 3 years, liberalized rent updates.
RDL 7/2019: extended minimum duration back to 5 years (7 if the landlord is a legal entity), and limited additional guarantees.
Law 12/2023 (Right to Housing Act): introduced the concept of large-scale landlord (gran tenedor), stressed market zones, and rent update limits.

Scope of application

The LAU applies to leases of the tenant's habitual and permanent dwelling (Art. 2 LAU). It does not apply to:

Luxury dwellings (floor área exceeding 300 m2 or rent exceeding 5.5 times the minimum wage).
Seasonal leases (tourism, studies, holidays).
Dwellings assigned by reason of position or service.

Duration of the Lease Agreement

Agreed duration and mandatory extensions (Art. 9 LAU)

The parties may freely agree on the contract duration. However, the LAU establishes a system of mandatory extensions in favor of the tenant:

If the agreed duration is less than 5 years (or 7 years if the landlord is a legal entity), the contract is mandatorily extended by annual periods until reaching a minimum duration of 5 years (or 7 years), unless the tenant expresses their wish not to renew with 30 days' notice before the expiry date.

Tacit extensión (Art. 10 LAU)

Once the minimum duration period (5 or 7 years) has elapsed:

If neither party notifies the other of their wish not to renew with at least 4 months' notice (landlord) or 2 months (tenant) before the expiry date, the contract is extended for annual periods up to a maximum of 3 additional years.

Landlord's need (Art. 9.3 LAU)

The landlord may recover the dwelling before the minimum period if the following circumstances exist:

The dwelling is needed as a permanent residence for themselves, their first-degree blood relatives or adopted family members, or their spouse under a final separation, divorce, or annulment judgment.
At least 1 year has elapsed since the contract was signed.
The landlord notifies the tenant at least 2 months before the date they need the dwelling.

If the landlord does not occupy the dwelling within 3 months of delivery, the tenant may choose between returning to the dwelling or receiving compensation equivalent to one month's rent for each remaining year of the contract (Art. 9.3 in fine LAU).

Rent: Setting and Updating

Freedom of agreement (Art. 17 LAU)

Rent is free: landlord and tenant may agree on whatever amount they consider appropriate. However, in stressed residential market zones (declared under Law 12/2023), there are limits:

For new contracts in stressed zones: rent may not exceed the rent of the previous contract (once the update clause has been applied) except in exceptional cases.

For contracts by large-scale landlords in stressed zones: rent may not exceed the reference index determined by law.

Annual rent update (Art. 18 LAU)

Rent is updated annually according to the mechanism agreed in the contract. Law 12/2023 has introduced fundamental changes:

2024: updates are limited to 3% (eleventh additional provisión of Law 12/2023).

2025 onward: the new Reference Index for the Annual Update of Residential Lease Agreements (IRAV) will apply, replacing the CPI as the reference index.

CPI and IRAV

CPI: until 2023, the most common mechanism was updating according to the year-on-year Consumer Price Index published by the INE. If the contract did not specify an index, the IGC (Competitiveness Guarantee Index) applied, with a 2% cap.
IRAV: the new index, provided for in Law 12/2023, aims to prevent rent increases from exceeding general price trends. Its calculation incorporates the CPI but is designed to moderate increases.

Update procedure

The update requires:

That one year of the contract has elapsed.
Written notice from the landlord to the tenant, indicating the applicable variation percentage and the resulting new rent.
The new rent applies from the month following the notice (Art. 18.3 LAU).

Deposit and Additional Guarantees

Mandatory deposit (Art. 36 LAU)

The deposit is mandatory and non-negotiable:

One month's rent for residential leases.
Two months' rent for leases for purposes other than housing (commercial premises, offices).

The landlord is obliged to deposit the security deposit with the corresponding body of the Autonomous Community (INCASOL in Catalonia, IVIMA in Madrid, etc.). Failure to deposit may result in penalties.

The deposit is not updated during the first 5 years (7 if a legal entity). After that period, it is updated to the amount of one month of the current rent.

Additional guarantees (Art. 36.5 LAU)

In addition to the deposit, the landlord may require additional guarantees, with a limit:

The amount of additional guarantees may not exceed 2 months' rent (Art. 36.5 LAU, as drafted by RDL 7/2019).

Guarantees may take the form of: additional deposit, bank guarantee, rent default insurance, or personal guarantee from a third party.

Exception: if the landlord is a large-scale landlord (owner of 5 or more dwellings, or 10 under Law 12/2023), they may not require additional guarantees beyond the mandatory deposit in stressed market zones.

Return of the deposit

The landlord must return the deposit within 1 month from the return of the keys (Art. 36.4 LAU). If not returned within that period, legal interest accrues. The landlord may deduct from the deposit amounts necessary to repair damage attributable to the tenant exceeding normal wear and tear.

Tenant Rights

Right of permanence (Arts. 9-10 LAU)

The tenant has the right to remain in the dwelling for the minimum period of 5 years (7 if legal entity), regardless of the duration agreed in the contract.

Right of first refusal (Art. 25 LAU)

If the landlord decides to sell the leased dwelling, the tenant has:

Right of pre-emption (tanteo): to be informed of the sale at least 30 days in advance, being able to purchase the dwelling under the same conditions as the proposed buyer.

Right of redemption (retracto): if the sale is carried out without prior notice or under different conditions, the tenant may step into the buyer's position within 30 days of learning of the sale.

This right may be expressly waived in the contract (Art. 25.8 LAU), which is common practice.

Right to carry out accessibility works (Art. 24 LAU)

A tenant with a disability, or who lives with a person with a disability or over 70 years old, may carry out accessibility works without the landlord's consent, provided they do not affect the building's structure.

Right of withdrawal (Art. 11 LAU)

The tenant may withdraw from the contract after 6 months from its signing, giving the landlord at least 30 days' notice. The contract may provide for compensation equivalent to one month's rent for each remaining year of the contract (prorated for periods of less than one year).

Subrogation on death (Art. 16 LAU)

If the tenant dies, the following may subrogate into the contract:

The spouse or de facto partner who was cohabiting.

Descendants who had been cohabiting for the two preceding years.
Ascendants who had been cohabiting for the two preceding years.
Siblings who had been cohabiting for the two preceding years.
Other persons with a disability of 65% or more who had been cohabiting.

Landlord Rights

Right to receive rent and associated amounts (Art. 17 LAU)

The landlord has the right to collect the agreed rent and associated amounts: general building expenses, individually metered services (water, gas, electricity), chargeable taxes (property tax, refuse collection tax).

Right to property conservation (Art. 21 LAU)

The landlord is obliged to carry out necessary repairs to maintain the dwelling in habitable condition (Art. 21.1 LAU), unless the deterioration is attributable to the tenant. The tenant must notify the landlord of any damage.

Minor repairs arising from ordinary use of the dwelling are the tenant's responsibility (Art. 21.4 LAU).

Right to recover the dwelling for need (Art. 9.3 LAU)

As analyzed above, the landlord may recover the dwelling for personal use or for direct family members, meeting the notice and timing requirements.

Right to terminate the contract (Art. 27.2 LAU)

The landlord may terminate the contract for the following reasons:

Non-payment of rent or associated amounts.
Non-payment of the deposit or its update.
Unauthorized subletting or assignment.
Willful damage or unauthorized works.
Annoying, unhealthy, harmful, dangerous, or illegal activities in the dwelling.
When the dwelling ceases to be the tenant's habitual residence.

Frequently Asked Questions About Lease Agreements

What is the minimum duration of a residential lease?

The LAU establishes an effective minimum duration of 5 years if the landlord is a natural person, and 7 years if a legal entity (Art. 9 LAU). If a shorter duration is agreed, the contract is mandatorily extended by annual periods until reaching that minimum, unless the tenant expresses their wish not to renew.

¿Can the landlord freely increase my rent every year?

No. Rent updates are regulated by Art. 18 of the LAU. For 2024, updates are limited to 3%. From 2025, the new IRAV index will apply. The landlord cannot update rent above these limits and must notify the tenant in writing.

How much should the deposit be for a residential lease?

The mandatory legal deposit is one month's rent for dwellings (Art. 36.1 LAU). Additionally, the landlord may require additional guarantees up to a maximum of 2 months' rent (Art. 36.5 LAU). In total, the initial outlay cannot exceed 3 months' rent plus the first month's payment.

¿Can the tenant leave before the contract ends?

Yes. The tenant may withdraw from the contract after 6 months from signing, giving the landlord 30 days' notice (Art. 11 LAU). The contract may provide for compensation of one month's rent per remaining year, prorated for periods of less than one year.

What happens if the apartment I am renting is sold?

The buyer is subrogated into the landlord's position and must respect the contract until its completion (Art. 14 LAU). If the contract is not registered with the Land Registry, the tenant has the right to remain for at least 5 years (7 if legal entity) from the date the contract was signed. Additionally, the tenant has pre-emption and redemption rights unless expressly waived (Art. 25 LAU).

Who must pay for repairs in a rented apartment?

The landlord is responsible for necessary repairs to maintain the dwelling in habitable condition (Art. 21 LAU): plumbing, electrical, structural, central heating. The tenant is responsible for minor repairs arising from ordinary use (Art. 21.4 LAU): changing a light bulb, unclogging a drain, replacing a gasket.
