Having just arrived in Spain, I’ve been looking for an apartment in Barcelona recently, and dealing with agencies has been a real headache, especially when it comes to the deposit. The explanations were all over the place—one month’s legal deposit, two months’ additional deposit, something about a bank guarantee… I was totally lost. After making a few mistakes and consulting friends who have lived here for years, I’ve finally figured it all out. I’m sharing this to help anyone else who’s currently apartment hunting.
Fianza (Legal Deposit) and Garantía Adicional (Additional Guarantee) Are Two Different Things
First, it’s crucial to understand that there are two types of “deposits” you’ll encounter when renting, but they are legally distinct.
Fianza (Legal Deposit): This is mandated by law, and its amount is strictly regulated. According to Spain’s Urban Leasing Law (Ley de Arrendamientos Urbanos), for long-term residential leases, a landlord can only ask for an amount equivalent to one month’s rent as the legal deposit, separate from any [rental agency fees]. This money is not held by the landlord but must be deposited with the official authority of the corresponding autonomous community. It serves as a guarantee that the tenant will fulfill their contractual obligations, such as paying rent on time and maintaining the property.
Garantía Adicional (Additional Guarantee): In addition to the legal deposit, the landlord and tenant can agree on an extra guarantee. This is where many agencies and landlords have more leeway. The law states that this additional guarantee cannot exceed two months’ rent. It can be in the form of a cash deposit or a bank guarantee (aval bancario). Many landlords require this to screen for tenants with stronger financial standing.

So, What’s the Total Deposit Amount?
Therefore, the maximum total deposit a landlord can legally ask for is: 1 month’s legal deposit (Fianza) + 2 months’ additional guarantee = a total of 3 months’ rent. If an agency or landlord involved in a potential rental scams asks for more than this, it’s illegal! Always read your contract carefully. Of course, in practice, many [Spanish rental agencies] may only ask for the one-month legal deposit, or perhaps one additional month, depending on the demand for the property and the landlord’s requirements.
| Deposit Type | Legally Mandated Amount | Deposited With |
| Fianza (Legal Deposit) | Equivalent to 1 month’s rent | Official regional authority |
| Garantía Adicional (Additional Guarantee) | Maximum of 2 months’ rent | Landlord or by mutual agreement |
When the contract ends, if there’s no damage to the property and all utility bills are paid, the landlord must return these deposits. The return of the Fianza requires the landlord to request it from the official authority, which can take some time. The additional guarantee is returned directly by the landlord. If a landlord unreasonably withholds your deposit, don’t just accept it. You can start by sending a formal notice, and if that doesn’t work, you may need to take legal action. I hope everyone finds their ideal apartment without any deposit troubles!
