Managing residential property in the Basque Country (Euskadi) requires navigating a dual-layer legal system: the national Ley de Arrendamientos Urbanos (LAU) (effective since 1 January 1995) and the regional Basque Housing Law (Law 3/2015) (effective since 26 September 2015). This region is known for its high level of autonomous control and strict administrative requirements.
1. The Basque Regulatory Landscape
The Basque Country has one of the most proactive housing policies in Spain. Landlords in Bilbao, San Sebastián, and Vitoria must comply with:
- The LAU (Law 29/1994): Governing the contract structure, duration (Art. 9), and mandatory security deposits (Art. 36).
- Basque Housing Law (3/2015): Establishing the social function of housing (Art. 4) and the registry of empty homes.
- Law 12/2023 (Tense Zones): Euskadi has a legal framework for applying rent caps in declared "Tense Zones" (Zonas Tensionadas), such as Errenteria and parts of San Sebastián.
2. Central Role of Bizilagun
Every landlord in the Basque Country is legally bound to interact with the territorial delegation of the Basque Government department competent in housing (often referred to via the Bizilagun service):
- Mandatory Deposit: Security deposits for urban properties (1 month for housing) MUST be lodged with the corresponding territorial delegation of the Basque Government.
- Compliance Checks: The Basque Government actively monitors the deposit registry to cross-reference with tax filings (Hacienda Foral).
3. Key Compliance Areas
- Rent Caps: In declared Tense Zones, rent increases for new contracts are strictly limited by the State Reference Index for large landlords and previous contract rates for small landlords, as per the framework established by national and regional laws.
- Energy Efficiency: Owners have a legal duty to maintain buildings in conditions of energy efficiency as established by regional housing standards.
- Technical Inspection (ITE): The Technical Inspection of Buildings is mandatory for buildings of an age established by regulation. Inspections are recorded in the Registry of Technical Inspections of Buildings of the Autonomous Community of Euskadi.
