Deposit Rules

  • The security deposit (fianza) is capped by law at one month's rent for a standard residential lease (two months for non-housing/commercial premises).
  • The landlord is legally required to deposit your fianza with the relevant regional housing authority (e.g. Comunidad de Madrid, INCASÒL in Catalonia) rather than simply keeping it themselves — ask for proof it was deposited.
  • The deposit does not accrue interest for you, and must be returned within one month of the lease ending and keys being handed back.

Lease Length & Renewal

  • Under Article 9 of the Ley de Arrendamientos Urbanos (LAU), a residential lease has a legal minimum duration of 5 years if your landlord is an individual, or 7 years if the landlord is a company — even if your signed contract states a shorter term.
  • If the contract term is shorter than that legal minimum, it is automatically extended year by year until it reaches the minimum, unless you (the tenant) give at least 30 days' notice that you don't want to renew.
  • After the minimum term, the contract can tacitly extend for up to 3 more years (Article 10 LAU) unless either side gives proper notice — 4 months for the landlord, 2 months for the tenant.

Rent Increases

  • Mid-lease rent increases must follow whatever index is specified in your contract; landlords cannot raise rent arbitrarily outside the agreed terms.
  • In areas designated as 'tensioned market zones' under Spain's 2023 Housing Law, additional caps apply to how much rent can rise, including on renewal.

The Gotcha

Spanish tenant protections run the opposite direction from the usual 'watch out' gotcha: once you sign a residential lease, the law effectively guarantees you up to 5 years of tenancy (7 if your landlord is a company), even if the contract itself says something shorter — your landlord can't simply decline to renew year to year during that window. Combined with the deposit legally having to sit with a regional government agency rather than the landlord's own account, tenant protections in Spain are considerably stronger than most Americans expect coming from an at-will rental market.
