Sharp Summer Surge in Unlicensed Listings

Barcelona City Council has detected a 47% increase in illegal tourist apartments between May and August 2026, identifying 525 unlicensed accommodations in August alone, up from 358 in May. The rise comes despite a 10% year-on-year decrease compared to August 2025, when 582 illegal listings were found. The data, reported by 3CatInfo and verified against the Council's official figures, highlights the persistent challenge of short-term rental regulation in the city.

Residents Report Daily Disruptions

In Barceloneta, residents like Núria describe living with constant disruption. She told Catalunya Ràdio that tourists damage elevators with heavy suitcases, break entrance locks, and scuff stairwell walls. "You see different people coming and going all the time," she said. "You start to wonder, aren't these tourist apartments banned here? But they're everywhere." Officially, only 85 tourist-licensed apartments are registered in Barceloneta, compared to 1,799 in Dreta de l'Eixample and 821 near Sagrada Família. Residents say the actual number of flats used for short-term rentals far exceeds the legal count.

Enforcement and Platform Cooperation

The City Council's Inspection Services Directorate (DSI), with over 30 technicians, uses automated web-scraping tools, known as 'spiderwebs', to monitor platforms like Airbnb and Booking. Since 2018, inspectors have deactivated over 16,000 illegal listings and opened more than 11,500 enforcement files. Since 2016, the Council has issued nearly 11,600 cessation orders and over 11,500 fines, reducing the average number of active illegal apartments from around 6,000 to about 300 detected advertisements per month.

We are stepping up monitoring and enforcement, especially during peak seasons, to protect residents' quality of life.

In 2025, the Council and Airbnb signed a cooperation agreement requiring hosts to verify property ownership or authorisation and to display valid tourist license numbers for stays under 32 days. The platform claims it now blocks listings without verified licenses and removes repeat offenders immediately. However, Airbnb still hosts the vast majority of illegal listings, accounting for 90% of Barcelona’s short-term rental market, though the company says it is complying with the agreement.

While summer 2026 saw a spike in illegal ads, the overall trend since early 2025 is downward. In April 2025, 822 illegal listings were detected; by April 2026, that number had dropped to 419, a 50% reduction. City Council sources say continued data sharing with platforms and faster deactivation rules (within 48 hours for first violations) are helping curb the problem, but enforcement remains a daily challenge in high-demand neighbourhoods.
