How Barcelona's Short-Term Rental Crackdown Created a Visual Identity Crisis — and How the City Is Fixing It

Barcelona's housing enforcement machine has a ghost problem. Thousands of property listings in the city's official short-term rental registry carry duplicate, recycled, or misattributed images — photographs that have been reused across multiple licence applications, swapped between addresses, or lifted wholesale from one flat in Gràcia and reattached to another in Poble Sec. The Ajuntament de Barcelona acknowledged the scale of the problem earlier this year when it flagged inconsistencies in the visual records underpinning its 2024–2026 rental compliance audit.

The issue matters right now because Mayor Jaume Collboni's administration has staked significant political capital on its short-term rental crackdown. In November 2023, Collboni announced that the city would not renew any of the approximately 10,101 tourist apartment licences when they expire in 2028 — a landmark declaration that put Barcelona at the centre of Europe's debate on over-tourism. But enforcement depends on accurate records, and accurate records depend on images that actually match the properties they are supposed to document.

A Loophole Built Over Years

The roots of the duplicate-image problem stretch back to the explosive growth of the platform economy after 2012, when Spain's regional governments were still scrambling to write the rules. In Catalonia, the legal framework for habitatges d'ús turístic — tourist-use dwellings — was formalised under Decree 159/2012. Operators filing for licences with the Generalitat's tourism registry, managed by the Agència Catalana de Turisme, were required to submit photographs, but verification was largely administrative rather than technical. There was no automated deduplication check comparing images across applications.

By the time Airbnb's Barcelona listings peaked at around 16,000 in the late 2010s, the registry held tens of thousands of images uploaded by landlords, property managers, and intermediary agencies. Some operators managing portfolios across the Eixample, Sant Martí, and the Gothic Quarter simply reused stock images or interior shots from one property across several applications. Others made honest errors. The result was a database that enforcement inspectors — working under the city's Oficina de l'Habitatge and the regional tourism inspectorate — found increasingly difficult to rely on when conducting physical compliance checks.

A 2022 audit by the Sindicat de Llogateres, the Barcelona tenant advocacy organisation, identified dozens of active listings on major platforms where the registered address and the displayed photographs did not correspond. The group documented cases in the Sant Antoni market area and along Carrer del Consell de Cent where the same set of interior photographs appeared attached to properties listed at different street numbers. Those findings fed directly into the political pressure that eventually produced Collboni's 2023 licence non-renewal announcement.

What the City Is Doing About It

The practical fix is more technical than dramatic. The Ajuntament has been working with its urban data unit, Barcelona Dades, to apply perceptual hash algorithms — a form of digital fingerprinting for images — to the roughly 17,000 image files still active in the municipal licence database. The process flags near-identical images across separate licence records for human review. A pilot run completed in early 2025 on listings in the Sagrada Família corridor identified more than 340 suspected duplicate image sets, according to municipal documentation circulated at a housing committee session in March 2025.

Each flagged case requires an inspector to cross-reference the image against the physical property record, the cadastral entry held by Spain's Dirección General del Catastro, and any platform listing still live under that licence number. It is slow work. The city has assigned additional staff to the Oficina de l'Habitatge office on Carrer del Bisbe Caçador to handle the caseload before the 2028 licence expiry deadline creates a final rush.

For landlords and operators still holding valid licences, the practical implication is straightforward: if a property's registered images do not clearly and uniquely correspond to that specific address, the licence is at risk of being flagged during the final compliance sweep. Legal advisers working with the Col·legi d'Administradors de Finques de Catalunya have been telling clients since late 2024 to proactively audit their submissions and file corrected image sets with the registry before the city's automated review reaches their postcode. Getting ahead of the deduplication process is considerably cheaper than contesting an enforcement action once it arrives.
