Residential rentals in Spain are governed by a legal framework that has changed significantly in recent years, especially since the Law on the Right to Housing went into effect. Landlords and tenants today face a more complex landscape than they did a decade ago: new rent adjustment indices, areas where rent is capped, specific definitions for large landlords, and contractual obligations that it’s important to understand before signing any lease.
When people refer to “rental law” in Spain, they are not referring to a single law, but rather to a combination of two legal texts that coexist and complement each other: the Urban Lease Law, which has regulated the contractual aspects of renting for decades, and the Law on the Right to Housing, passed in 2023, which introduced new mechanisms aimed at curbing prices and protecting the most vulnerable groups.
The Urban Lease Law, enacted in 1994, is the law that regulates the essential aspects of any residential or commercial lease agreement in Spain: term, renewals, security deposit, grounds for termination of the contract, and the rights and obligations of the landlord and tenant. Over the years, it has been amended several times to adapt to market changes, and it remains the primary reference for understanding how a rental agreement works in Spain.
While the LAU focuses on the contractual relationship between landlord and tenant, the Law on the Right to Housing incorporates public policy tools: it allows autonomous communities to designate areas with a tight residential housing market, creates the category of “large property owner” with specific obligations, and establishes a new benchmark index for adjusting rents. In practice, both laws are applied jointly: the LAU defines the general contractual framework, and the Housing Act adds additional restrictions in certain cases.
The regulatory framework governing rentals in 2026 combines the LAU with the new provisions introduced by Law 12/2023 and its subsequent implementing regulations, which have gradually defined aspects such as rent adjustments and the delineation of areas of housing market strain.
Among the most significant changes in recent years are the replacement of the CPI with a new benchmark index for adjusting rents under certain leases, the ability of autonomous communities to cap rent prices in high-demand areas, and the introduction of a legal definition of “large landlord” with enhanced obligations, particularly regarding lease renewals and protection against situations of vulnerability.
The IRAV, or Reference Index for the Adjustment of Residential Leases, is an indicator published monthly by the National Institute of Statistics that replaces the CPI as the benchmark for adjusting rent in primary residence leases signed on or after May 26, 2023. Its purpose is to prevent rents from rising at the same rate as general inflation, offering a more moderate and predictable increase for both landlords and tenants. Leases signed before that date will continue to be adjusted according to the index agreed upon by the parties at the time—usually the CPI—unless they decide to modify it by mutual agreement.
Rent adjustments may only be applied if the lease contains an express clause allowing for them: if no adjustment formula was agreed upon, the landlord cannot unilaterally raise the rent even if the reference index has risen. When such a clause does exist, the adjustment is applied once a year, coinciding with the lease’s anniversary date, using the most recent published figure for the relevant index at that time as a reference.
Areas with a tight residential housing market are geographic areas where the financial burden households must bear to access housing—whether for rent or ownership—has been determined to be particularly high. The designation of these areas is the responsibility of each autonomous community, which must justify it to the relevant ministry in accordance with the criteria established in Law 12/2023. Not all autonomous communities have made use of this option; therefore, its effects—primarily, the cap on the price of new rental contracts compared to previous ones—apply only in municipalities that have been formally designated as such.
A well-drafted rental agreement protects both the landlord and the tenant and prevents future disputes arising from omissions or ambiguities.
The contract must include the full identification details of the landlord and tenant, including name, identification number, and address for notification purposes, so that both parties are clearly identified in the event of any subsequent issues.
It is necessary to include a precise description of the property covered by the agreement: full address, cadastral reference, square footage, and, if applicable, whether it is being rented with furniture or appliances, specifying which items are included.
The lease must specify the agreed-upon term, the rent amount and method of payment, the amount of the statutory security deposit, and—if agreed upon—any additional guarantees, such as a bank guarantee or a supplementary security deposit, the limits of which are regulated by applicable regional and state laws.
The parties may include additional clauses provided they do not contradict the provisions of the LAU, such as a prohibition on subletting, the allocation of community fees or utility costs, or specific conditions regarding the use of certain common areas of the property.
Certain clauses—such as the tenant’s waiver of rights recognized by the LAU, the imposition of disproportionate penalties, or the exemption from liabilities that legally fall on the landlord—may be considered unfair and, therefore, void, even if the parties have signed them.
The term of leases for primary residences is subject to a system of mandatory extensions that protects the tenant from the landlord’s desire to terminate the lease early.
When the landlord is an individual, the lease is automatically extended year by year until it reaches a minimum duration of five years, unless the tenant expressly states their intention not to renew it.
If the landlord is a legal entity, such as a company or an investment fund, the mandatory extension is extended to seven years, offering additional protection to the tenant against large institutional landlords.
Once the agreed-upon term or the mandatory extension period has expired, if neither party notifies the other of their intention not to renew the lease with the required advance notice, the lease is tacitly extended for additional one-year periods.
Both the landlord and the tenant must give notice of their intention not to renew the lease at least four months in advance for the landlord and two months in advance for the tenant, prior to the termination date of the lease or any of its extensions.
The tenant may terminate the lease at least six months after it is signed, provided they give the agreed-upon minimum notice—usually thirty days—and the landlord may demand compensation if so agreed in the lease.
The initial rent is freely set between the parties, except in areas with a tight residential housing market, where additional limits may apply to new contracts.
Leases signed before May 26, 2023, retain the originally agreed-upon adjustment index, while those signed on or after that date must be adjusted in accordance with the IRAV, unless they are leases excluded from its scope, such as seasonal leases or those for non-residential use.
The IRAV is mandatory for primary residence leases signed on or after May 26, 2023, that contain a rent adjustment clause. Seasonal leases, room rentals, or leases for non-residential uses fall outside its scope and may continue to be adjusted according to what the parties freely agree upon.
The landlord must notify the tenant in writing of the rent adjustment before it takes effect, specifying the index applied, the percentage change, and the resulting final amount, so that the tenant can verify that the calculation complies with current regulations.
In addition to the monthly rent, renting a home involves a series of expenses and guarantees that should be clearly understood from the outset.
The LAU mandates a security deposit equivalent to one month’s rent for primary residence leases; this amount must be deposited with the relevant regional authority and may not be offset against the final monthly payments of the lease without the express agreement of both parties.
The fees for the real estate agency managing the rental are generally paid by the landlord, unless the tenant expressly requests the agency’s services. Utilities are usually the tenant’s responsibility during the term of the lease, while property tax and homeowners’ association fees are, unless otherwise agreed, the landlord’s responsibility.
Upon termination of the lease, the landlord has a legal timeframe to return the security deposit to the tenant, after verifying that the property is returned in proper condition, deducting, where applicable, any damages not attributable to normal wear and tear from use of the property.
The tenant has a number of rights recognized by law, but also obligations that must be fulfilled throughout the term of the lease.
The tenant is obligated to pay the agreed-upon rent on time and to maintain the property in good condition, taking responsibility for minor repairs resulting from the ordinary use of the property.
The tenant has the right to enjoy the dwelling normally, without unjustified interference from the landlord, who may not enter the property without the tenant’s consent except in exceptional cases that have been previously agreed upon or are justified.
The landlord also has legal obligations that must be fulfilled to ensure the property remains in suitable living condition.
The landlord must carry out all necessary repairs to keep the dwelling in habitable condition, except for those that are the tenant’s responsibility due to damage attributable to the tenant’s own use.
The landlord may reclaim the dwelling before the mandatory extension period ends if they can demonstrate a justified need, such as using it as a permanent residence for themselves or a first-degree relative, provided that this was expressly provided for in the lease agreement.
During the term of the lease, the need for repairs or renovations may arise, and responsibility for them depends on their nature and cause.
Repairs necessary to maintain the dwelling in a usable condition—such as malfunctions in general utilities or damage resulting from wear and tear—are the landlord’s responsibility, unless they result from misuse by the tenant.
Minor repairs resulting from normal wear and tear—such as maintenance of everyday appliances or small, routine fixes—are the tenant’s responsibility during the term of the lease.
The tenant may not carry out renovations that alter the layout of the property without the landlord’s express consent, and the landlord may require that the property be restored to its original condition at the end of the lease if such renovations were carried out without authorization.
There are several legal grounds that allow a lease agreement to be terminated before its term expires.
Nonpayment of rent, unauthorized subletting, or engaging in disruptive or illegal activities in the property are grounds that allow the landlord to request termination of the lease and, if necessary, initiate the appropriate legal proceedings to reclaim the property.
In addition to grounds for breach of contract, the landlord may reclaim the property for justified need, provided that the legal requirements and time limits for this scenario are met.
The sale of a rented property does not in and of itself terminate the lease agreement: the new owner is subrogated to the rights and obligations of the previous landlord, unless the lease was not registered in the Property Registry and certain circumstances provided for in the LAU apply.
The tenant has a right of first refusal to purchase the residence they occupy in the event of a sale and may exercise this right under the conditions and within the timeframes established by law, unless the parties have expressly waived this right in the lease agreement.
In areas designated as having a tight residential housing market, additional rules apply aimed at curbing rent prices and strengthening tenant protection.
In these areas, new rental contracts generally may not exceed the rent set in the most recent valid contract for the same dwelling, except in cases specifically provided for by law. In addition, the law defines a “large landlord” as any individual or legal entity that owns a specified number of urban residential properties, establishing stricter obligations for these owners regarding lease renewals and rent caps.
The regulations provide for mechanisms to grant extraordinary extensions to leases in situations where the tenant is in a state of particular social or economic vulnerability, as well as specific procedures designed to prevent homelessness before proceeding with an eviction.
The legal framework for rentals varies considerably depending on their purpose. Regular housing rentals, intended to meet the tenant’s permanent housing needs, enjoy the greatest legal protection, with mandatory extensions and limitations on rent increases. Seasonal rentals, intended to meet temporary needs such as a work- or study-related relocation, are largely excluded from these protections and allow for greater flexibility in setting and adjusting rent. Tourist rentals, on the other hand, are governed by specific regulations—generally at the regional or municipal level—that are geared toward tourist use rather than primary residence.
Only if the lease includes an explicit adjustment clause and the corresponding index is applied—whether the one originally agreed upon or the IRAV for leases subject to it; without such a clause, the rent cannot be adjusted unilaterally.
The landlord may refuse to renew the lease only after the mandatory extension period has expired, provided they give the required advance notice, or before that period if they can demonstrate a justified need that was previously agreed upon in the lease.
Generally speaking, the tenant has the right to remain in the property for the duration of the mandatory extension period, which is five years if the landlord is an individual and seven years if the landlord is a legal entity, unless there is a legal basis for early termination.
No. The landlord may not enter the rented property without the tenant’s consent, except in exceptional circumstances and always while respecting the tenant’s right to privacy and peaceful use of the property.
The lease agreement remains in effect, and the new owner assumes the position of the previous landlord, subject to the agreed-upon terms, except for specific exceptions provided for in the LAU.
In the event of a breach of contract, both the landlord and the tenant may pursue civil legal action, and in certain autonomous communities, there are also mediation or arbitration services for housing matters that can be utilized before initiating legal proceedings.
Now that you understand how rental legislation works in Spain, it’s important to remember that participating in the real estate market doesn’t necessarily mean buying a home or managing a lease agreement.
Today, there are alternatives that make it easier to enter this sector with a lower initial investment. Domoblock offers the opportunity to invest as little as €200 in real estate through asset tokenization, with a 100% online process backed by blockchain technology. In addition, each investment opportunity is pre-screened by specialists to select projects with appreciation potential, facilitating access to the real estate market without the traditional barriers.
Rental legislation in Spain currently combines two layers of regulations that you should be familiar with before signing any contract: the Urban Lease Law, which regulates the essential aspects of the relationship between landlord and tenant, and the Law on the Right to Housing, which introduces additional mechanisms for rent control and protection in high-demand areas. Understanding the renewal terms, rent adjustment rules, the obligations of each party, and the specific characteristics of high-demand areas allows you to approach any rental agreement—whether as a landlord or a tenant—with greater legal certainty and fewer surprises throughout the term of the contract.
