About one in three Airbnb properties in Mallorca show irregularities
Associated with properties with irregularities in Mallorca.
This is not an abstract estimate. These are properties that are active right now.
We analyzed 10,691 listings in Mallorca and cross-checked them with the official register. 2,686 show at least one irregularity.
Mallorca’s housing pressure is not only about supply. It also comes from listings that do not line up with the public register. While some hosts follow the rules and keep within capacity, others operate with more beds, more revenue and fewer restrictions.
That money is not neutral. It is money that competes directly with those who do comply.
If you own property, you are competing against this. If you manage homes, you are carrying this risk. If you are a neighbour, this is where many of the problems you see begin.
You don't need to interpret data or make estimates.

Year by year: where the money stacks up
This is not a one-off issue. It persists over time and grows when nightly rates rise.

The 216 million euro headline did not appear overnight. The bars show modelled irregular money for each calendar year. The visible drop in 2020 reflects the pause in tourism during the COVID-19 pandemic.
Why does the chart climb? More listings and higher nightly prices lift the euro total. For example, versus 2025, modelled irregular revenue in 2026 is up by about 18%. That jump is driven mostly by those higher nightly rates, not a huge increase in rule-breaking listings. Although the share barely moves, the money tied to these irregularities keeps growing.
That means this is not a one-off problem.
It is probably something you already have close by.
From 2017 to 2026, the modelled irregular total is much higher at the end of this window than at the start. That long climb matches what locals describe in rents, noise and unfair competition on the ground.
The problem is not correcting itself naturally.

How we detect irregularities
We do not guess. Each property we analyze is cross-checked with the official public register. When the listing and the license do not match, we record a possible irregularity.
Main irregularities we detect
- No license number: the listing shows no identifier
- Not in the register: the number shown does not appear in the official register
- Capacity or location discrepancies: listing details do not match the license
- Duplicated licenses: the same license appears on several different homes
One of the most frequent signals behind this volume is duplicated licenses. You can see how they are distributed in the duplicated licenses analysis.
In today’s snapshot, the most frequent irregularity is Duplicated license, with 1,402 cases. One property can show several irregularities.
Irregularity breakdown
Each row counts how often that indicator appears, not unique properties. Do not add the figures to reconstruct the total irregular count.
| Category | Count |
|---|---|
| Missing license | 156 |
| Unregistered license | 470 |
| Duplicated license | 1,402 |
| Capacity mismatch | 635 |
| Location mismatch | 531 |
What these data points indicate
A large share of tourist money in Mallorca is still tied to properties that show discrepancies with the public register.
- Structural pattern: the share of properties with irregularities stays around 32% year on year
- Economic impact: even with a relatively stable share, the total amount grows when activity and nightly rates rise
- Direct impact: if you are an owner, agency or neighbour, this issue is already part of the market you operate in
- Enforcement risk: operating without a valid license can mean fines between €40,001 and €400,000
This is not only a legal question. It is a question of competition, pricing and direct pressure on the market.
The impact is not spread evenly across the island either. You can see where it concentrates in the ranking of municipalities with the most irregularities.
Most of these irregularities are not visible at a glance.
And without checking, it is impossible to know whether a property is compliant.
Before you buy, rent, publish or manage a home, check whether it matches the public register.
It's a seconds-long check that can prevent serious problems.
