Airbnb Puts the Balearic Islands Under Pressure: Deleting Illegal Listings — What It Means for Mallorca

Airbnb takes on illegal holiday rentals in the Balearic Islands – a clear signal, but is it enough?

Last week, in the sun with a strong espresso at the Plaça del Mercat, I overheard two landlords talking: from mid-October Airbnb plans to remove listings without an official registration number – first on Ibiza, then also on Mallorca, Menorca and Formentera. In the streets of Palma, on Calle Sant Miquel and in Santa Catalina you can immediately sense the relief among residents who have had enough of late-night parties, piles of rubbish and the constant coming and going.

What exactly does the platform plan – and why is it more than a click?

Airbnb intends to filter out listings without a valid registration number. In practice this means: apartments in multi-family buildings, rooms in illegal micro-apartments and sometimes even dubious offers like boats or wild camps should disappear. Authorities on Ibiza report thousands of removed listings already. For Mallorca, where investigations suggest that roughly one in four listed properties lacks a permit, this would be a real cut – several thousand apartments and more than 40,000 beds are at stake.

The central question: does this ease the problems – or just shift them?

That is the crux. Deleting listings does not automatically make them disappear. The measures can reduce noise and vacancies in neighborhoods like La Lonja or Portitxol in the short term, but illegal providers have simple ways out: other platforms, renamed listings, bookings outside the platform or the use of intermediaries with seemingly valid numbers. The devil is in the details of the technical implementation and in the cooperation between platforms, municipalities and police.

Aspects that are rarely discussed

1) Data gap and speed: Authorities must keep registration data up to date and exchange it directly with platforms. Without automated data matching every deletion will be a drop in the ocean.
2) Rental contracts and ownership relations: Many long-term rental agreements are secretly converted into short-term rentals – often without the landlord's knowledge or that of the community of owners. Municipal control powers are limited here.
3) Economic displacement: Hoteliers welcome the measure, but there is a risk of a shift to commercial short-term renting or to informal networks that operate in the shadows of tax and labor law.
4) Social consequences: If thousands of apartments are taken out of the market legally, more housing may become available in the short term — but there will also be pressure on tenants from rising prices if owners seek to secure returns elsewhere.

Concrete opportunities and approaches

Deleting listings is only the beginning. For the measure to be effective, three levers are needed:

1. Better digital cooperation. A real-time interface between municipal databases and platforms would make filtering automatic. That way listings don't have to be checked for days while guests keep arriving in the neighborhood.
2. Sanctions and on-site controls. Fines, joint checks with police and municipal staff, and the ability to forward information about repeat offenders to banks and tax authorities. Those who repeatedly rent illegally must face serious financial consequences.
3. Incentives instead of just bans. Small landlords should get easier access to legal models: clear, simple registration, transparent fees and contact persons in the municipalities. A hotline in Palma that quickly confirms a registration number would be a start.

And the neighbors?

Many conflicts start with an overflowing bin or a loud party in the early morning. Practical advice: talking to the landlord or calling the municipality often helps more than a long legal battle. At the same time, neighborhoods like Es Born and Molinar need reliable contact points so complaints can be documented and follow-up inspections can be carried out.

In the end, it remains unclear how consistently the measures will be implemented. The announced deletions from October are a clear signal — but whether illegal renting will be dried up depends on the technology, the will of local authorities and the platform's determination. Anyone booking this island season should check the registration number before booking and ask questions. And city administrations should, at the next market visit to the Plaça del Mercat, do more than talk over coffee — they should take the data into their own hands.

The island atmosphere with the smell of the sea, the rumble of motorbikes and market conversations will benefit — provided the authorities keep up and don't just talk about the sunny side.
