Following the landmark Housing Law passed in May 2023, annual limits on rent hikes remain, but a new official index now determines the maximum increase for the latest contracts. The law, developed through coalition government, EH Bildu, and ERC support, directly affects anyone renting property in Spain: tenants, landlords, families, and businesses. Below is a detailed guide to your rights and obligations for rent adjustments in 2025.
Understanding Rent Increase Limitations
The Housing Law’s core purpose is affordability and market stability. It establishes enforceable rent caps for ongoing contracts, protects tenants from excessive rises, and clarifies both owner and tenant rights. In 2025, annual rent increases remain strictly limited by law, and new rules mean both contract date and type now impact how increases are calculated. For most tenants, affordability is improved and sudden cost shocks are prevented.
2025: New Index for Rent Updates
From January 1, 2025, Spain has replaced the previous CPI-based model with a new index published monthly by the National Statistics Institute (INE), known officially as the Rent Update Index (IRA/IRAV). This index sets the benchmark for legal rent increases across Spain for contracts signed after May 25, 2023.
Landlords must not raise rents above these values—regardless of contract wording or inflation. Example: A €1,000/month rent contract signed after May 25, 2023, may only be increased to €1,022 in 2025 (2.2%), not the 3% or more that was provisional before the new index launched.
Rent Increase Caps and Contract Clauses in 2025
The Housing Law still requires every lease to specify its rent revision mechanism (how/when rent is increased), written into the contract and agreed by both sides. However, as of 2025, any contract provision that allows a higher increase than the official index may only apply the index value—no exceptions. If no clause is present, the IRA/IRAV or CPI will apply by default, according to the signing date. Tenants must review renewal offers carefully and should request written breakdowns of any increase before signing extensions.
Landlords legally must notify tenants of planned increases, and must adhere to deadlines, notice periods, and all documentation required by law. In 2025, Spain’s Ministry of Housing provides monthly rent index figures, so tenants can check whether owners are complying.

Conclusion
Spain’s rental housing sector in 2025 is governed by the Housing Law 12/2023 and its new annual Rent Update Index, providing strict caps and official reference values, currently 2.2%. Whether you are a tenant or a landlord, knowing and applying these limits is critical. Always confirm any rent revision uses the official INE-published index and seek legal clarification for complex situations, renewals, or special cases.
