Rental Security Deposit: What It Is and How It Works 2026

Renting a home is one of the most common real estate transactions in Spain. One of the key elements that both tenants and landlords must properly manage is the security deposit. This financial guarantee, which covers the lease term, is legally required in most contracts, and proper handling of it can help prevent future disputes.

In a context where rental prices remain high in many Spanish cities, understanding how the security deposit works, how much must be paid, where it is registered, and under what conditions it is returned is essential for both parties. In this article, we take an in-depth look at the key aspects of rental security deposits, including recent legal updates, return deadlines, and practical guidance for tenants and landlords.

What is a rental security deposit?

A security deposit is a sum of money that the tenant pays to the landlord as a guarantee against potential damage to the property or non-payment of rent. This deposit is refunded at the end of the lease, provided there are no outstanding debts or damage attributable to the tenant.

In Spain, the main regulations governing security deposits are set forth in the Urban Leasehold Act (LAU), which establishes the conditions for their payment and refund.

How does it work?

The rental security deposit is a protection mechanism for the landlord, but it also safeguards the tenant’s rights.

The purpose of the security deposit is to guarantee payment of rent; if the tenant stops paying, the landlord can use the deposit to cover the unpaid months. It also serves to cover damage to the property; if the tenant causes damage beyond “normal wear and tear,” the landlord can deduct the repair costs from the deposit. Furthermore, it ensures compliance with the terms of the lease; for example, if the tenant fails to pay the homeowners’ association fees or leaves utility bills unpaid, the landlord may withhold part of the security deposit.

The rental security deposit is refundable; provided there are no breaches of contract, the tenant receives 100% of the deposit back at the end of the lease. This amount must be deposited with a public agency; the landlord is required by law to deposit the security deposit with the appropriate agency in the autonomous community and may not keep it in a private account. In addition, the security deposit earns interest in some autonomous communities, which is paid to the tenant annually.

The security deposit is different from other additional payments, such as the last month’s rent or other supplementary guarantees. Although the law requires only one month’s deposit for primary residences, landlords may request additional guarantees. These must be justified and agreed upon by both parties. The security deposit is also different from a bank guarantee, which may sometimes be required in addition to the deposit. They are separate legal concepts.

When and how is the security deposit paid?

This may be at the time of payment; in this case, the security deposit is paid when the lease is signed, along with the first month's rent or, in some cases, an agency fee (if a real estate agency is involved).

It is recommended to use secure payment methods to avoid problems; therefore, it is essential to pay by bank transfer (never in cash, unless a receipt is signed). You should request a receipt or proof of payment and include details in the contract such as the amount of the security deposit, the payment date, and the bank account into which the payment was made.

If the landlord does not provide a receipt, the tenant may request written confirmation of payment. If the landlord refuses, it is advisable to keep the bank statement as proof of payment.

Regarding the deadline for the final deposit, the landlord has up to 30 days to deposit the security deposit with the appropriate government agency (IVIMA, AVRA, INCASOL, etc.). If the landlord fails to do so, the tenant may file a complaint against the landlord.

How much will the payment be in 2026?

The legally required amounts vary depending on the type of lease. Therefore, for a primary residence, the minimum security deposit is equal to one month’s rent, but a higher amount may be required depending on the autonomous community, such as in Madrid or Catalonia, where it is permitted to agree on a security deposit of up to two months’ rent for residential properties.

In the case of commercial premises, the minimum security deposit is currently two months’ rent, and no more or less may be required unless otherwise agreed upon by both parties.

If the landlord requests more than the legally permitted amount, the situation should be evaluated. If there is no valid legal justification, the tenant may file a complaint with the housing authority in their autonomous community.

Where is the security deposit paid?

Under the law, the landlord must deposit the security deposit with the appropriate agency in the autonomous community.

In Andalusia, the responsible agency is AVRA; in Catalonia, payments must be made to INCASOL; in Madrid, the designated agency is IVIMA; and in Valencia, it is AVIVA.

The deadline for depositing the security deposit is one month from the signing of the lease agreement. If the landlord fails to deposit the security deposit with the designated public agency, the tenant may claim its return with interest.

Who is required to pay it?

The tenant is responsible for paying the security deposit; this is one of their obligations, along with ensuring that the landlord deposits the security deposit with the relevant government agency, for which they may request a receipt.

The landlord’s obligations include depositing the security deposit with the appropriate public housing authority within 30 days and returning it at the end of the lease, provided there are no damages or outstanding debts.

In special cases, such as subletting, the subtenant typically pays the deposit to the original tenant. In shared housing arrangements, each tenant pays their proportional share of the deposit.

When and how is the security deposit returned to the tenant?

The security deposit must be returned within a maximum of one month from the date the keys are handed over, provided there are no outstanding rent payments, no damage to the property, and all utility bills have been settled.

The return process is as follows:

First, the tenant must notify the landlord or managing agency of their departure. An inspection of the property is then carried out. If everything is in good condition, a request is submitted to the relevant authority where the deposit was registered to process the refund.

In what circumstances can part or all of the security deposit be withheld?

The landlord may withhold the security deposit if there is damage to the property beyond normal wear and tear, if there are outstanding debts—whether for rent, building maintenance fees, or utility bills—or if the tenant leaves the apartment before the agreed-upon date and without notice.

For example, if a window is broken and the repair costs around €200, that amount may be deducted from the security deposit.

Tips to Avoid Problems with the Security Deposit

For Landlords

The landlord must deposit the security deposit with the relevant government agency to avoid fines and claims; a detailed inventory must also be prepared upon moving in and moving out, including photos and a description of the property’s condition. The landlord must document any major repairs with invoices and estimates, and must return the security deposit within one month to avoid complaints.

For Tenants

The tenant should always pay the rent by bank transfer, never in cash or without a receipt. In addition, the tenant should inspect the property upon moving in and moving out, sign a condition report, and request proof that the security deposit has been properly registered. It is also advisable to report any damage in writing to avoid being held responsible later.
