The security deposit, known in Spain as the fianza, is a mandatory payment that protects the landlord against property damage or unpaid rent. This document reflects the requirements of the Ley de Arrendamientos Urbanos (LAU), effective 1 January 1995, and the specific regional regulations of Cantabria under Decreto 3/2015. Failure to comply with registration requirements can lead to severe financial penalties and the loss of certain tax benefits for the landlord.
Statutory Deposit Amounts
According to Article 36 of the LAU, the mandatory security deposit for residential leases is equivalent to one month's rent. While the parties can agree on additional guarantees (such as a bank guarantee or an additional deposit), the law limits these extra financial guarantees to a maximum of two additional months' rent for leases with a duration of up to 5 years (7 for legal entities), unless the lease is for a longer term.
Mandatory Registration in Cantabria
In Cantabria, the landlord is legally obligated to deposit the fianza with the Dirección General de Vivienda, which is part of the Government of Cantabria's administrative structure. This requirement is governed by Decreto 3/2015, de 29 de enero.
- Deposit Deadline: The landlord must complete the deposit within 15 business days (días hábiles) from the date of the lease execution (Decree 3/2015, Art. 7.1).
- Deposit Method: The landlord must use the official forms and submit them to the regional treasury along with the signed lease contract.
- Verification: Tenants have the right to request proof that the deposit has been registered.
- Consequences of Non-Compliance: Failure to deposit the fianza within the deadline can result in surcharges (up to 20%) and fines, and prevents the landlord from claiming personal income tax (IRPF) deductions related to the rental property.
Return of the Security Deposit
Upon the termination of the lease and the return of the keys, the landlord has a period of one month to return the deposit to the tenant, provided there are no damages beyond normal wear and tear or outstanding utility bills. If the landlord fails to return the deposit within this timeframe, it will begin to accrue interest at the legal rate (Interés Legal del Dinero).
- Deductions: The landlord must justify any deductions from the deposit with invoices or receipts for repairs or unpaid expenses.
- Mediation: If the parties disagree on the amount to be returned, the dispute may be resolved in the Juzgado de Primera Instancia of the judicial district where the property is located.
Regional Administrative Specifics
