INE, monthly IRAV publication
Published as a monthly series. Quoting one annual figure is the most common error in English-language coverage of Spanish rent caps.
Flat Spain tracks Spain's rent-increase cap through the IRAV, the index that replaced CPI-linked rises for residential leases. There is no single "2026 IRAV": the index is published monthly, and the value that applies to your lease is the one for the month your annual review falls in. March 2026 was 2.47%; the 2025 average was 2.20%.
The index is monthly, so the question 'what is the 2026 IRAV' has no answer. English pages that give one are usually quoting whichever month they happened to check, or an annual average, and the difference between the values in circulation — 2.14%, 2.20%, 2.47% — is large enough to matter on a year's rent.
The value that binds is the one for the month of your review. A lease signed in March is reviewed against March's index, not against an average and not against the value that was current when you signed.
Temporada contracts escape the cap. A lease written as seasonal rather than as a habitual residence is not subject to the same increase limits, which is one of the reasons the temporada framing spread. If your contract is labelled temporada but you live there as your home, the cap question and the contract-type question are the same question.
Still published elsewhere, and wrong
If you found a different number, it is probably one of these.
- "The 2026 IRAV is 2.14%"
- A single month's index quoted as if it were an annual figure. There is no annual IRAV — always cite the month.

Frequently asked questions
What is the maximum rent increase in Spain in 2026?
It depends on the month your annual review falls in. The IRAV is published monthly — 2.47% in March 2026, against a 2025 average of 2.20% — and the applicable value is the one for your review month.
Does the rent cap apply to an 11-month temporada contract?
No. Seasonal contracts sit outside the residential rent-increase cap, which is part of why they became so common. If you live in the property as your home, whether the contract is genuinely seasonal is the question to settle first.
