Government Approves €180 Million for Rent-Capped Zones

The Official State Gazette (BOE) published Royal Decree 851/2026 on 22 October 2026, dated 21 October, regulating the direct granting of subsidies for strained residential market areas. Approved by the Ministry of Housing and Urban Agenda, the measure mobilises a budget of €180 million (technically allocated as €189,999,992) to finance public land, and the purchase and refurbishment of social housing in 317 Spanish municipalities.

What's Changing

The new regulation develops the mechanisms outlined in Article 18 of State Law 12/2023 on the Right to Housing and directly transfers funds to the five autonomous communities that have declared rent-capped zones: Catalonia, Basque Country, Navarre, Galicia, and Asturias. The funds are subject to four mandatory lines of action:

• Acquisition and urbanisation of public land for residential use.
• Promotion and refurbishment of properties intended for social or affordable rent.
• Direct purchase of properties by public administrations to incorporate them into their public rental housing stock.
• Public coverage and guarantees against potential unforeseen rent defaults for young people and vulnerable groups.

The decree also introduces a strict patrimonial requirement: properties acquired, promoted, or refurbished with these funds will be permanently classified as protected housing, eliminating any future option for voluntary declassification.

Who is Affected

The decree covers a universe of over 9 million residents spread across 317 municipalities declared rent-capped. Unlike other state population-based allocation programmes, Royal Decree 851/2026 links the budget exclusively to territories that have applied rent containment limits.

The direct beneficiaries of the investment are public administrations and housing applicants registered in public social rental registries. For private owners, the measure consolidates the legal framework for price containment and strengthens public intervention in the residential supply of these municipalities.

What it means if you own a property in Catalonia

Catalonia is the main recipient of the state package: it will receive €119,471,633, representing over 66% of the total national allocation for the 2026 fiscal year. This concentration is due to the fact that 271 of Spain's 317 rent-capped municipalities are located in Catalonia, according to data from the Department of Territory, Housing and Ecological Transition of the Generalitat.

The management of these funds falls to the Generalitat and executing entities such as INCASÒL (Catalan Land Institute), which will coordinate purchases and promotions with local councils. In regions such as Vallès Occidental, Vallès Oriental, or Moianès, municipalities like Sabadell, Terrassa, Granollers, or Caldes de Montbui will see strengthened municipal interventions on land and existing housing.

For those renting a property in these locations, the decree does not modify the rules for calculating rent caps or the use of the state Reference Index, but it will increase the volume of public rental housing available in urban areas in the medium term.

What to Do Now

If you are an owner and have a property for rent or plan to put one on the market in a rent-capped municipality, it's advisable to review your strategy based on three aspects:

1. Verify your municipality's status: confirm whether your locality is formally listed among the 271 municipalities declared rent-capped in the Official Gazette of the Government of Catalonia (DOGC) to understand the caps applicable to your property.
2. Monitor potential public pre-emption rights: if you plan to sell entire properties or housing portfolios in these localities, regional and local administrations have strengthened funds to exercise pre-emption and redemption rights over residential properties.
3. Adjust rental contracts: ensure contracts are aligned with current update criteria and properly document initial conditions to avoid disputes or administrative penalties.
