Spain Rent Increase Calculator IPC 2026 with 3% Legal Cap

According to Spain's Law 12/2023 on the Right to Housing, the maximum annual rent increase for primary residences in 2024 and 2025 is limited to 3% by law. This limit applies even if the IPC (Consumer Price Index) is higher.

No, it is not mandatory by law. For the rent to increase, the lease must include an explicit clause mentioning annual adjustments. If no such clause exists, the initial agreed price remains in effect for the duration of the contract.

The landlord must notify the tenant in writing at least one month (30 days) before the new rent takes effect. If notice is given later, the increase only starts counting from the following month after notification.

Even if the IPC published by Spain's INE (National Statistics Institute) is 5% or 6%, a landlord cannot legally demand more than a 3% increase for primary residences in 2026. Any attempt to charge more is legally challengeable.

The limit typically does not apply to commercial spaces, industrial warehouses, offices, or independent garage spaces. These are governed by what the parties freely agree upon in the contract.
