Commercial Rent Review Process in basque country
Identify the Index
Check if the contract specifies the General IPC index or a specific regional variation.
Calculate the Variation
Apply the percentage change of the index over the last 12 months to the current rent.
Written Notification
Notify the tenant in writing (email or letter) at least one month before the new rent takes effect.
Payment Receipt
The new rent is due from the month following the notification.
1. Exemption from Residential Caps (Ley de Vivienda)
It is a common misconception that the recent Spanish Housing Law (Law 12/2023) caps commercial rent increases at 3%.
- No Caps for Businesses: Commercial leases for offices, retail stores, or warehouses are NOT subject to any statutory price caps.
- Full IPC Recovery: Landlords can apply the full General Consumer Price Index (IPC) increase, even if it exceeds 10%, provided the contract explicitly allows for it.
2. The Necessity of the Written Clause
In the Basque Country, as in the rest of Spain, silence in the contract regarding rent reviews means the rent is frozen.
- Art. 18 LAU Supletory Rule: If the commercial lease does not include a specific clause detailing how and when the rent will be updated, the landlord cannot legally increase it for the entire duration of the contract (and its extensions).
- Drafting Tip: Always include a clause referencing the "Índice de Precios de Consumo (IPC) General Nacional" published by the INE.
3. Statutory Increase for Assignment and Subletting (Art. 32 LAU)
One unique feature of the LAU for commercial properties is the right to increase rent when the tenant changes without the landlord's consent:
- Lease Assignment (Traspaso): If the tenant assigns the lease to a new company, the landlord has the right to a 20% rent increase by law, unless the contract waives this right.
- Partial Subletting: If the tenant sublets part of the premises, the landlord is entitled to a 10% rent increase.
- Notice: The tenant must notify the landlord of the assignment or sublease within one month of it taking place.
