Tunis Municipality Moves to Purge Duplicate Images From Public Records — Here's Why It Matters to You

The Tunis municipal administration has launched a structured audit of its digital image archives, targeting thousands of duplicate photographs and scanned documents that have accumulated across departmental servers over the past decade. The cleanup — confirmed in a public notice posted at the Hôtel de Ville on Avenue Habib Bourguiba earlier this week — is expected to run through September 2026 and will touch records held by the urban planning directorate, the cadastral office and at least four arrondissement councils.

This might sound like a bureaucratic housekeeping exercise, but residents who have tangled with the city's permit and property systems will know the practical damage that duplicate files cause. When two versions of the same plot survey or building façade photograph sit in a database with slightly different metadata, clerks pull the wrong one. Applications stall. Appeals drag on. In the Medina and in rapidly developing districts like El Menzah and La Marsa, where construction permit requests have surged since 2023, even a two-week administrative delay can cost a homeowner or small contractor real money.

What the Problem Actually Looks Like on the Ground

The core issue is how the archives grew in the first place. When the municipality digitised its paper records between 2018 and 2022, scanning was contracted in batches to different vendors. Overlapping scan runs produced identical images filed under different reference numbers. Staff at the Agence Foncière Urbaine — the national land agency whose regional office operates near the Bab Saadoun axis — have reportedly processed files where the same cadastral photograph appears under three separate plot identifiers, each linked to a different owner claim. That kind of duplication does not just slow down clerks; it creates genuine legal ambiguity that can freeze property transactions entirely.

In the Cité El Khadra neighbourhood, residents applying through the online municipal portal introduced in January 2025 have encountered error messages generated precisely because the system detects conflicting image records for the same parcel and flags the application for manual review. Manual review queues, according to the municipality's own published service-level data from the first quarter of 2026, averaged 19 working days — nearly four times the stated three-to-five day target for routine permit queries.

What the Audit Means in Practice for Residents

The deduplication project uses hash-matching software to identify byte-for-byte identical files and a secondary visual-similarity check for images that were scanned twice at slightly different resolutions. Files flagged as duplicates are not immediately deleted; they are moved to a quarantine folder and a nominated officer in each arrondissement council has 30 days to confirm or dispute the classification. The municipality says the window is deliberately generous precisely because errors in property records carry legal consequences.

For residents with active permit applications or pending property transfers, the practical advice is straightforward: check your application reference number against the municipal portal before the end of July. If your file shows a status of en attente de vérification documentaire — awaiting document verification — it may have been caught in a preliminary deduplication sweep. The relevant contact point is the guichet unique at the Arrondissement Municipal de la Médina on Rue Sidi Ben Arous, or the equivalent service windows in La Marsa and El Menzah for residents in those zones.

The Municipality of Tunis has not published a full cost estimate for the project, but comparable digital-archive cleanups carried out by Casablanca's municipal authority in 2024 and by the Tunis-based Centre National de l'Informatique in earlier internal pilots suggest that deduplication of a corpus this size typically reduces storage overhead by between 25 and 40 percent. The more meaningful saving, though, is in staff time: every hour a clerk spends chasing a duplicate image is an hour not spent processing the next application in the queue.

The audit's first progress report is scheduled for presentation to the Conseil Municipal in late August. Residents and neighbourhood associations that want to flag specific files they believe are affected can submit a written request through the municipality's documented-complaint channel before 31 July 2026.
