The Parliament of Catalonia has approved the 2026 budget companion law, a measure that changes housing rules and other legal provisions linked to this year's Generalitat budget. For tenants, landlords and property professionals, one of the clearest immediate effects is a new definition of a large housing holder in Catalonia: a person or entity with five homes in Catalonia or 10 across Spain.

The law was passed hours after the chamber approved the Generalitat's 2026 budget. The companion law, known in Catalan as the llei d'acompanyament, is used to introduce related changes to taxes, fees and sector rules that sit alongside the spending plan. The text published by the Parlament de Catalunya also includes measures affecting airport governance, giving the Catalan government a stronger role in that area.

Residents trying to work out whether housing rules apply to their landlord can check the current official guidance from the Catalan housing department. Readers can also review how we handle official documents and verification in our Editorial Policy.

What changes for large landlords in Catalonia

The companion law defines a large landlord as someone who owns:

  • Five homes in Catalonia, or
  • 10 homes across the whole of Spain.

That matters because the label of gran tenidor, or large landlord, is used in Catalan housing regulation, including rules connected to pressured residential market areas and some obligations in the rental market. The Generalitat's housing department already publishes guidance on how the category is applied in practice.

The official FAQ for stressed housing market zones, known in Catalan as Zones de Mercat Residencial Tensat, explains how rent cap rules interact with landlord status. These are areas where housing costs are considered under pressure compared with local incomes and supply.

The approved law classifies a large housing holder as a person or entity with five homes in Catalonia or 10 in Spain.

The Parliament's official bulletin and the text later published in the Boletín Oficial del Estado, Spain's state gazette, are the legal references for the final wording.

Airport powers shift toward the Catalan government

The law also expands the Catalan government's powers in airport matters, according to the approved text. The source material provided does not set out all operational consequences in detail, but the change increases the Generalitat's role in decisions affecting airports.

For travellers, airport workers and businesses that depend on air links, the practical impact will depend on how the new powers are used and whether further regulations or agreements follow. The Generalitat and Parliament documents describe this as part of the wider legal package attached to the 2026 budget.

Why the companion law matters beyond the budget vote

Companion laws are separate from the main budget figures but often have direct effects on daily life because they adjust the legal framework around public policy. In this case, the approved package covers housing and transport governance alongside tax and administrative changes.

The 2026 budget bill had already moved through the parliamentary process earlier this year, including the full debate stage. The final companion law was then approved after the budget itself received the chamber's backing.

Key documents in the approval process

  • The budget companion law was published in the Parliament's official bulletin.
  • The Generalitat had previously sent the draft law to the CTESC, Catalonia's Economic and Social Work Council, for consultation.
  • The final law was also published in the BOE, giving it state-level official publication.

Anyone affected by the housing changes should check the final official wording and the Generalitat's housing guidance, especially if they are renting or managing property in a regulated area.
