How Duplicate Photos Are Quietly Draining Los Angeles City Servers — and What the Numbers Reveal

Los Angeles city agencies are sitting on tens of millions of duplicate digital images — redundant files accumulated across decades of scanning, uploading, and migrating records — and the cost of storing them is not trivial. An internal audit framework circulated among Information Technology Agency staff earlier this year estimated that duplicate imagery across municipal systems can account for anywhere from 18 to 35 percent of total stored files in large-scale government archives, based on benchmarks published by the National Archives and Records Administration.

The issue has taken on fresh urgency in 2026, as the city races to build out digital infrastructure ahead of the 2028 Olympic Games while simultaneously managing the data burden created by Mayor Karen Bass's housing emergency declaration — a directive that has generated thousands of permitting scans, inspection photographs, and site-assessment images across the city's planning and building departments since it was signed in January 2023.

Where the Redundancy Lives

The Department of City Planning's office on Spring Street downtown and the Los Angeles Housing Department's processing center in Van Nuys are two of the heaviest generators of duplicate image files, according to the ITA's working framework. Every permit application for emergency shelter conversion, for example, can trigger multiple uploads of the same site photograph — once by the applicant, once during staff review, and again when the file is archived. Multiply that across the roughly 13,500 accessory dwelling unit permits the city processed in fiscal year 2024–2025, and the redundant file count climbs fast.

LAPD body-worn camera footage presents an even larger-scale version of the same problem. The department's Digital Evidence Management System, operated in partnership with Axon Enterprise, stores footage at multiple resolutions and often retains duplicate exports created during discovery requests. Storage contracts for municipal body-cam programs in comparably sized U.S. cities — Chicago and Houston have both published procurement figures — have run between $4 million and $9 million annually depending on retention policy. Los Angeles has not published a standalone figure for its Axon storage costs, but the city controller's office has flagged digital storage as a growing line item in technology budget reviews going back to fiscal year 2022.

The Cost of Doing Nothing

Deduplication software is not new. Tools from vendors including Veritas and Iron Mountain can identify and flag redundant files algorithmically, typically recovering 20 to 40 percent of occupied storage capacity in a first pass, based on published case studies from municipal deployments in Dallas and Philadelphia. At current commercial cloud rates — roughly $0.023 per gigabyte per month on Amazon Web Services' standard tier as of July 2026 — even a modest 50-terabyte recovery across city systems translates to about $13,800 saved annually. Scale that to petabyte-level archives and the savings become a meaningful budget argument.

The Los Angeles County Metropolitan Transportation Authority has already moved in this direction. Metro's digital asset management overhaul, announced in late 2024 as part of its broader Olympic readiness program, included a deduplication audit of its construction-documentation image libraries — files generated by contractors photographing progress on the Purple Line extension through Century City and the Crenshaw/LAX line. Metro has not released final figures from that audit, but the agency cited storage efficiency as one of three goals in its procurement documents.

For city agencies still running legacy content management systems — some of the planning department's document workflows date to software implemented before 2010 — the practical path forward involves phased migration rather than a single system swap. Technology consultants who have worked on comparable municipal projects in New York City and Seattle recommend starting with the highest-volume intake points: permit portals, evidence management platforms, and GIS imagery libraries. Los Angeles's GIS layer alone, maintained by the city's Bureau of Engineering on Figueroa Street, pulls satellite and aerial photography updates that can create overlapping archived snapshots if retention rules are not carefully configured.

The ITA has included digital storage hygiene as a line item in its 2026–2027 budget request, which the City Council's Budget and Finance Committee is expected to take up in September. For departments already strained by the demands of wildfire documentation in the wake of the January 2025 Palisades and Eaton fires — each of which generated thousands of aerial damage-assessment images — the financial case for cleaning up duplicate data before the Olympic clock runs out is becoming harder to ignore.
