Aragon Landlord-Tenant Laws: Complete Guide

Renting out residential property in Aragon (encompassing Zaragoza, Huesca, and Teruel) requires navigating the national Ley de Arrendamientos Urbanos (LAU) alongside specific regional administrative rules. Unlike some regions that have deregulated deposits, the Government of Aragon (DGA) strongly enforces its centralized deposit custody, recently rolling out an entirely new digital system in late 2025.

Key Aragon Rental Laws at a Glance

Security Deposits (Fianza) and the WFIA System

Under the LAU, collecting a security deposit equivalent to one month's rent is unavoidable for a primary residence. Landlords can request additional guarantees up to a maximum of two additional months' rent.

Strict Regional Rules: Aragon continues to demand that landlords surrender this one-month deposit to the regional administration (DGA) within two months of signing the lease. To streamline this historically tedious process, Aragon launched the WFIA (Web Fianzas Aragón) platform in November 2025, which allows landlords to fully self-manage, deposit, and withdraw funds online electronically.

Rent Control and Increases

To increase a tenant’s rent, the lease must explicitly contain a rent-update clause. If it does, you must follow strict national limits that apply across Aragon:

• 2024 Cap: Increases were limited to a maximum of 3%.
• 2025 and beyond: Rents are decoupled from inflation (IPC). Landlords must use the new State Reference Index implemented by the National Statistics Institute (INE), which enforces tighter, lower control limits.

For more detail, see our Rent Increases guide.

Eviction Procedures (Desahucios)

Removing an entrenched tenant requires navigating the Spanish court system (Ley de Enjuiciamiento Civil). Self-help evictions are criminal offenses in Spain. Common grounds for eviction in Aragon include:

• Non-payment of rent or utilities.
• Unauthorized subletting.
• Intentional property damage.

The process strongly requires initiating communication with a formal warning (a Burofax) granting the tenant 30 days to clear debts. If unpaid, a formal lawsuit via an attorney (abogado) and court representative (procurador) becomes necessary, culminating in a judge-ordered eviction (lanzamiento).

Maintenance and Habitability

Under Article 21 of the LAU, landlords are obligated to make all necessary structural and general repairs to guarantee the property remains habitable.

Conversely, the tenant is strictly responsible for all small repairs caused by ordinary, daily wear and tear. A landlord cannot raise the base rent simply because they had to fix a broken boiler or replace faulty plumbing outside of the tenant's negligence.

Lease Requirements

Though verbal agreements are admitted under Spanish doctrine, they are dangerous. A residential lease in Aragon must outline the parties, the rent, and clearly map the property. The tenant is highly protected: regardless of a short initial term (e.g., a 1-year contract), they have the absolute legal right to unilaterally renew the lease for up to 5 consecutive years (if the landlord is an individual) or 7 consecutive years (if the landlord is a legal entity/company).

Navigating Compliance in Aragon

Executing compliance correctly in Aragon requires mastering the state-level LAU while vigilantly managing the DGA's strict 2-month deposit windows via WFIA. Landager offers the tools to centralize these tasks, preventing administrative fines and ensuring your property investments in Zaragoza, Huesca, or Teruel remain structurally and legally sound.
