Duplicate Images on Tunis City Portals Are Costing Residents Time and Trust

Walk into the Commune de Tunis service counter on Avenue Habib Bourguiba on any given morning and there is a good chance the clerk will hand you a printed page featuring a photograph of a building that looks nothing like the one you are asking about. It is not a new problem. Digital records held by several Tunis municipal departments have accumulated layers of duplicate and mis-attributed images over years of platform migrations, with the same stock photograph appearing under three or four different neighbourhood listings, project pages, or permit applications at once.

The issue has come into sharper focus this spring because the Agence de Réhabilitation et de Rénovation Urbaine — known by its acronym ARRU — began digitising a backlog of urban development files covering work carried out in Medina districts between 2019 and 2024. During that process, according to a technical briefing note circulated to partner organisations in May 2026, staff identified more than 400 instances where a single image had been duplicated across multiple property or project records, in some cases causing a file linked to Rue de la Kasbah to display photographs actually taken in the Hay El Khadra district.

Why Duplicate Images Are More Than a Housekeeping Problem

For residents applying for construction permits, heritage restoration grants, or social-housing assessments, the wrong photograph attached to the wrong address can trigger delays of weeks. A permit officer reviewing a file who sees an image inconsistent with the site description may flag it for manual verification. In a system where ARRU has publicly stated its target turnaround for standard renovation approvals is 30 working days, even a single verification hold can push a file past that window, leaving homeowners unable to begin contracted work on time.

The problem also erodes something harder to quantify: community trust in digital government. Residents in Ariana and Ben Arous have increasingly relied on the Tunisian Ministry of Equipment and Housing's online GeoPlatform — launched in its current form in late 2023 — to cross-reference neighbourhood development plans with their own properties. When the platform surfaces duplicate images, users cannot easily tell whether they are looking at their block or a street several kilometres away. Civic technology advocates at the Tunis-based association Opendata TN flagged this specific issue in a February 2026 workshop held at the Cité des Sciences on Boulevard Mohamed Bouazizi, noting that image metadata attached to municipal records is rarely standardised before upload.

The financial stakes are real. ARRU's 2025 annual report — a public document — listed a portfolio of rehabilitation projects across the Greater Tunis area valued at roughly 180 million Tunisian dinars. Permit delays and documentation errors on even a small fraction of that portfolio translate into measurable cost overruns for both the agency and private contractors. One widely cited rule of thumb in construction project management holds that a two-week delay on a mid-size renovation in a dense urban area can add between three and five percent to total project costs, though that figure varies considerably by scope.

What Should Change, and What Residents Can Do Now

ARRU has said it plans to complete its deduplication review of digitised files by the end of the third quarter of 2026, a deadline that falls in late September. The agency is understood to be using open-source image-fingerprinting tools to flag duplicate files automatically before a human reviewer makes a final decision on which record is correctly attributed. Whether that timeline holds will depend partly on staffing at its Rue d'Espagne headquarters in downtown Tunis.

In the meantime, residents submitting permit applications or development queries to the Commune de Tunis or to ARRU are advised to attach their own dated photographs — timestamped with GPS metadata if possible — directly to any submission. Including a clear cover sheet that references the official cadastral parcel number, available free of charge through the Office de la Topographie et de la Cartographie, gives reviewers an anchor that is harder to confuse with a duplicate record. The OTC office on Rue Alain Savary in El Menzah handles public inquiries on weekdays until 3 p.m.

Longer term, the deduplication exercise under way at ARRU could become a model for other municipal agencies managing image-heavy digital archives. The Commune de Carthage and the Ariana municipal council both maintain online project galleries that civil society groups have noted carry similar duplication risks. Getting those records clean before the next wave of urban development files arrives is not a technical luxury — for the families waiting on permits in the Medina or in Ettadhamen, it is a practical necessity.
