TLDR: Spain just rolled out two new decrees, RDL 28/2026 and RDL 29/2026, that cap rent increases, extend lease terms, and freeze certain landlords out of the buying market through 2030. Rental supply has already dropped 15 percent this year, and critics on both sides say the law is either too weak or too harsh, depending on who you ask.
What the New Decree Actually Changes
On October 6, 2026, Spain’s Official Gazette published Royal Decree-Law 29/2026 alongside its companion, RDL 28/2026. Together they build on the 2023 Housing Law and go further than most people expected.
The headline change is a temporary freeze. Between now and December 31, 2030, certain buyers, including large institutional investors and anyone trying to pick up property below market value to dodge social housing rules, will face restrictions on acquiring residential units. Tenants also get stronger pre-emptive purchase rights, meaning they get first crack at buying the place they’re renting if the owner decides to sell.
Primary residence leases are getting longer too, and annual rent hikes are getting capped. That part isn’t new in concept (Madrid and Barcelona landlords have lived under similar limits since 2024), but RDL 28/2026 locks in a steadier framework instead of the patchwork of yearly caps the market has dealt with until now.
Who Counts as a “Large Landlord”
The law splits property owners into two camps, and which one you fall into determines almost everything. Small landlords, roughly 85 percent of Spain’s rental stock according to the Ministry of Housing, still have more flexibility. Large landlords, defined as anyone holding ten or more units (or sometimes five, depending on the region), face registration requirements and have to report rental data straight to their regional housing authority.
SOCIMIs, Spain’s version of a REIT, got hit from another angle entirely. The decree adds a new tax on undistributed profits for these entities, which is clearly aimed at pushing big institutional players to either lower rents or sell off units.
Why Rental Supply Keeps Shrinking
Here’s the part that should worry renters more than anything in the decree itself. The Ministry of Housing reported a 15 percent drop in available rental listings during the first quarter of 2026, the steepest decline since the original Housing Law took effect back in 2023.
That’s not a coincidence. When a law tells landlords they can’t charge what they want, some of them simply stop renting long-term and look for other ways to use the property.
The Furniture Fee Workaround
In a handful of cities, something close to a shadow market has formed. Tenants and local housing groups describe contracts where the official rent sits neatly under the legal cap, but a separate “furniture rental” or “consultancy” fee gets tacked on outside the lease. It’s not exactly illegal on paper, but it defeats the whole point of the cap, and regulators haven’t figured out how to stop it yet.
Barcelona’s Fight to Bring Tourist Flats Back
Nowhere is the tension sharper than in Barcelona, where Mayor Jaume Collboni has pushed hard to force short-term tourist apartments back into the long-term residential pool. His argument is straightforward: every flat rented out to tourists on a weekly basis is one less home available to an actual resident.
A FEDEA analysis published in June 2026 gave the city’s approach a mixed but notably positive review, finding that rental prices in Barcelona have been kept in check since the law came into force, even if landlords grumble about it constantly.
What Economists Are Saying
Not everyone’s convinced the numbers add up in tenants’ favor long term. Analysts at CaixaBank Research expect the rental market to stay under pressure right through 2026, regardless of how many new public housing units break ground.
The Scale of the Housing Deficit
Their estimate is blunt. Even with new construction projects and government-backed land deals (where the state hands over public land to private developers who build and manage controlled-rent housing for 50 to 75 years), Spain’s accumulated housing shortfall could pass 600,000 units by the end of the decade. A law that caps rents doesn’t build a single new apartment on its own, and that gap isn’t closing anytime soon.
What Happens Next for Tenants and Landlords
The real test comes over the next year, as regions decide how aggressively to enforce the stressed market zone rules and as small landlords figure out whether staying in the rental business still pencils out. Spain’s constitution also gives autonomous communities control over housing policy in ways that could still trigger legal fights over whether Madrid overstepped its authority.
For now, renters in places like Barcelona and Madrid have more protection on paper than they did three years ago. Whether that protection means more available homes, or just fewer landlords willing to offer any, is the question nobody in Spain has fully answered yet.
