Rental Deposit (Fianza) Rules in Spain: How Much, Who Holds It, When It's Returned
The rental deposit is one of the most universally required parts of a Spanish lease — and also one of the most misunderstood, mostly because the mechanics differ by region in ways that don't get explained clearly at signing time.
How much
Under Article 36 of the LAU (Ley de Arrendamientos Urbanos), the mandatory cash deposit is:
- One month's rent for a housing lease.
- Two months' rent for a lease used for something other than housing (e.g. commercial premises).
This is a legal floor, not a suggestion — every housing lease in Spain requires at least this deposit. It's separate from, and not to be confused with, any additional guarantee like an aval bancario, which is optional and governed by different limits (see our fianza vs. aval bancario guide).
Who actually holds it
This is the part that surprises a lot of tenants and landlords alike: in most autonomous communities, the fianza isn't simply kept by the landlord in a drawer — it's required to be formally deposited with the relevant regional housing authority (the specific body and process vary by community). This exists precisely so the deposit isn't just informally "held" by one party with no oversight. The exact mechanism is regional, so check the requirement that applies in your specific autonomous community rather than assuming a single national process.
When it's returned
The general principle is straightforward: the deposit should be returned at the end of the tenancy, provided the property is left in the condition required by the contract (normal wear and tear aside) and there are no outstanding rent or agreed charges owed. Deductions for damage beyond normal wear, or for unpaid amounts, are the main legitimate reasons a landlord can withhold part or all of the deposit. The specific timeline for the refund is set at the regional level alongside the deposit-holding mechanism above — rather than quoting a single number that may not apply to your community, confirm the applicable timeline through your region's housing authority or a local professional.
Quick answers
Can a landlord ask for more than the legal minimum deposit? The fianza itself is fixed at one/two months by law — anything beyond that would fall under the separate rules for additional guarantees (like an aval bancario), which have their own legal limits rather than being unrestricted.
What counts as normal wear and tear vs. damage? This is inherently a judgment call and a common source of disputes — documenting the property's condition (photos, a written inventory) at move-in and move-out is the most practical protection for both sides, regardless of what the legal standard technically is.
What if the deposit isn't returned and there's no clear reason given? This is a genuine dispute scenario worth taking seriously rather than letting drop — the regional deposit-holding system exists partly to create a paper trail for exactly this situation. A tenant in this position should look into their region's specific process for disputing a withheld deposit.
