By the Numbers: Saint-Tropez's War on Duplicate Property Images Is Costing the Town Real Money

Saint-Tropez's municipal archive contains more than 14,000 registered property and tourism images, and according to an internal audit circulated within the Mairie de Saint-Tropez this spring, roughly 23 percent of those files are exact or near-exact duplicates. That single figure — one in four images redundant — is driving a broader conversation at the Hôtel de Ville about what it actually costs a small coastal commune to manage a bloated digital estate.

The timing matters. The town is midway through a €2.1 million digital infrastructure upgrade, formally launched in January 2026 under the regional Plan Numérique Provence-Alpes-Côte d'Azur. Clearing duplicate image data is not a headline project, but administrators responsible for the upgrade say it is consuming staff hours they had not budgeted for. Duplicate files inflate storage requirements, slow down the shared planning databases used by the Service Urbanisme, and — critically — create version-control errors when development dossiers for sites along the Quai Jean-Jaurès or in the Quartier de la Ponche are submitted with mismatched photographs across separate filings.

What the Numbers Actually Show

The audit identified three main sources of duplication. Planning submissions account for the largest share: applicants or their architects upload the same building photograph multiple times across amendment rounds, often because the digital portal does not flag identical file checksums. Tourism-related uploads — images submitted by operators on the Route des Plages and around Place des Lices for the commune's official listings — represent the second category. The third is internal: staff scanning paper documents that were already digitised years earlier.

Collectively, the 3,220 confirmed duplicate image files identified by April 2026 occupy approximately 47 gigabytes of server space hosted through the commune's contract with a Toulon-based data services provider. At the current contractual rate of €0.18 per gigabyte per month, that translates to roughly €8.46 in direct monthly storage cost for data the town does not need. The raw euro figure is small. The administrative cost is not. Each duplicate must be reviewed manually before deletion to confirm it is not, in fact, a distinct image that merely resembles another — a process the Service Informatique estimates at between 8 and 12 minutes per file. At 3,220 files, that adds up to between 430 and 640 staff hours.

At the median hourly cost of a municipal category B civil servant in the Var department — a figure cited in the 2025 Rapport sur l'État de la Fonction Publique Territoriale published by the DGCL — those hours represent a labour cost in the range of €11,000 to €17,000, dwarfing the storage bill by a factor of more than a thousand.

Local Pressure Points and the Path Forward

Two projects are making this urgent. The renovation dossier for the historic Chapelle de la Miséricorde on Rue de la Miséricorde involves 340 separate image files submitted by the project architect between 2023 and 2025 — of which 91 have been flagged as duplicates. A separate urban landscaping proposal for the area around Place de l'Ormeau submitted 58 images, 19 of them duplicates, creating a delay in the planning review cycle measured in weeks rather than days.

The commune's digital team is now piloting a perceptual hashing tool — software that detects visually similar images even when file names differ — on a trial batch of 500 records. If the trial, which runs through September 2026, achieves the 94 percent accuracy rate reported in comparable pilots by the Communauté d'Agglomération du Pays de Grasse, the Mairie intends to roll it out commune-wide before the end of the year.

For residents and property owners submitting planning applications in the meantime, the Service Urbanisme has published a one-page guidance note on the commune website asking applicants to label images with unique identifiers and avoid re-uploading unchanged files across amendment rounds. The note has been available since March 2026. How many applicants have read it is, as yet, unquantified.
