Barcelona Cracks Down on Fake Rental Photos in Housing Crisis

Barcelona's housing inspectors are raising alarms about a specific and growing problem inside the short-term rental market: duplicate images, the same photographs recycled across multiple listings to make one apartment look like several, or to disguise unlicensed properties behind the facade of a legitimate one. The practice has drawn renewed attention from the Ajuntament de Barcelona as Mayor Jaume Collboni's administration pushes deeper into its crackdown on platforms like Airbnb and Booking.com, which were ordered to remove thousands of unlicensed listings following a landmark city ruling that took effect in November 2028.

The timing matters. Barcelona is heading into its second summer under the expanded tourist tax regime, which raised the surcharge on cruise passengers and short-term rental guests earlier this year. City hall is simultaneously enforcing a hard cap of zero new tourist apartment licences in the Eixample and Gràcia districts, where rental pressure is most acute. Against that backdrop, landlords seeking to keep unlicensed flats in operation have become more sophisticated, and housing enforcement officials say duplicate imagery is one of the tools being used to evade detection.

How the Problem Works, and Who Is Spotting It

The mechanics are straightforward. A single apartment, say, a two-bedroom flat on Carrer del Consell de Cent in the Eixample, gets photographed once. Those images then appear across three or four separate listings, each with a slightly different address, price or description. To a human inspector scrolling through hundreds of listings, the duplication is easy to miss. To automated image-recognition software, it is not. The Institut Municipal d'Habitatge i Rehabilitació, Barcelona's municipal housing body, has been piloting detection tools that cross-reference listing photographs across major platforms. Housing policy researchers at the Universitat Pompeu Fabra, whose urban economics faculty has published extensively on Barcelona's rental market distortions, have noted that image duplication tends to cluster in neighbourhoods where enforcement pressure is highest, precisely because operators are trying to scatter their digital footprint.

Experts working with the city's data suggest the problem is not marginal. A 2025 study by the research group Housing Observatory, based at the Universitat de Barcelona's Faculty of Geography, found that in the Gothic Quarter and Sant Pere, Santa Caterina i la Ribera, duplicate or near-identical listing images accounted for an estimated 12 percent of active short-term rental advertisements in a sample month. That figure has not been independently verified by the Ajuntament, but municipal housing officials have cited similar internal estimates in planning documents reviewed by this newspaper.

What Comes Next for Enforcement

The practical question is what city hall can actually do about it. Barcelona's current legal framework allows inspectors to issue fines of up to €600,000 for operating without a tourist apartment licence, under regional Catalan legislation governing tourist accommodation. The Generalitat de Catalunya, which shares regulatory authority over the sector with the Ajuntament, updated those provisions in 2024. But fines are only useful if inspectors can prove which physical property corresponds to a fraudulent listing, and duplicate images deliberately obscure that link.

The Institut Municipal d'Habitatge i Rehabilitació is understood to be in discussions with the major platforms about mandatory metadata standards for listing photographs, including geolocation data that would make image duplication easier to trace back to a specific address. Residents' associations in the Barceloneta neighbourhood, where illegal tourist flats have been a source of sustained community tension since at least 2014, have formally requested that the city publish a public-facing dashboard showing enforcement actions taken against duplicate listings.

For renters and neighbours trying to report suspicious properties, the city's existing complaint channel, accessible through the Ajuntament's online habitatge portal, does allow image submissions as supporting evidence. Housing advocates at the Sindicat de Llogateres, the tenants' union that has been active in campaigns around the Passeig de Sant Joan and surrounding streets, recommend that residents screenshot listings they believe are duplicates and submit them with the specific platform URL and the date of capture. That paper trail, they argue, is what gives inspectors the best chance of acting before a listing disappears.
