How Los Angeles Is Tackling Duplicate Image Replacement in Public Records — and How It Stacks Up Against London and Tokyo

Los Angeles city archivists are midway through an overhaul of the municipal digital records system, targeting a problem that has quietly inflated storage costs and complicated public records requests for years: thousands of duplicate images embedded across permit files, planning documents, and infrastructure reports held by the Department of City Planning and the Bureau of Engineering. The effort, running under the city's broader Digital Services modernization initiative, puts L.A. in a race with several major world cities to solve a problem that sounds mundane but carries real administrative weight.

The timing matters. With the 2028 Olympics requiring the city to fast-track construction permits and environmental reviews for venues stretching from Inglewood's SoFi Stadium to the renovated Los Angeles Memorial Coliseum in Exposition Park, a clogged, redundant document system is not a theoretical inconvenience. Public records officers at City Hall have flagged that duplicate image files — the same scanned photograph or site plan filed under multiple case numbers — slow retrieval times and create legal ambiguities about which version of a document is authoritative.

What L.A. Is Actually Doing

The city contracted with its existing enterprise content management vendor in early 2025 to run deduplication scripts across roughly 4.2 million scanned document pages held in the Planning Department's Accela and Laserfiche systems. The work is concentrated on records generated between 2008 and 2022, when scanning protocols were inconsistent across different district offices, including the ones serving Hollywood, Boyle Heights, and the Harbor area near the Port of Los Angeles in San Pedro. Staff at the South Valley district office in Van Nuys have been among those manually reviewing flagged files that automated tools couldn't resolve cleanly.

The process involves more than deletion. When a duplicate image is identified, archivists must determine the canonical version, update metadata tags, and log the replacement in an audit trail that satisfies California Public Records Act requirements. That last step is what separates a clean records job from a legal liability. The city estimates it will complete Phase 1 — covering planning and building files — by the first quarter of 2027, before the bulk of Olympic-related permitting activity peaks.

How London and Tokyo Are Handling the Same Problem

London's approach offers an instructive contrast. The Greater London Authority began a comparable deduplication effort for its planning portal in 2023, focusing on the roughly 33 boroughs that feed documents into a shared Planning London Datahub. The GLA built its own open-source matching algorithm, publishing the tool on GitHub in March 2024 so other municipalities could adapt it. L.A. has not adopted that tool, instead relying on proprietary vendor software — a choice that records management professionals have noted limits the city's ability to audit or modify the underlying logic.

Tokyo's Bureau of Urban Development took a different path entirely, embedding image deduplication requirements directly into submission standards for new filings starting in January 2025, rather than conducting a retrospective cleanup. That upstream approach means Tokyo avoids accumulating the backlog that L.A. and London are now working through, though it required a two-year training rollout for roughly 1,200 municipal staff and licensed contractors who submit documents electronically.

Los Angeles has no equivalent submission standard in place yet. The Digital Services office has discussed a pilot requiring unique image verification for new Olympic venue permits, but no formal policy has been adopted as of July 2026.

For residents trying to pull records on a property in Silver Lake or a business license in Koreatown, the practical upshot is straightforward: response times on complex public records requests that involve scanned images remain slower than the city's own 10-day target under the California Public Records Act. The deduplication project, if it stays on schedule, should measurably reduce that lag by late 2027. Anyone filing a records request now involving pre-2022 planning documents should budget extra time and consider submitting through the city's online NextRequest portal, which at least allows status tracking, rather than by email or walk-in at the Figueroa Plaza offices downtown.
