L.A. Is Quietly Purging Duplicate Images From City Records — Other Global Cities Are Already Years Ahead

Los Angeles city agencies spent roughly $2.3 million in fiscal year 2025 on storage and licensing fees tied partly to redundant digital assets sitting across at least a dozen municipal databases — a problem that has prompted the city's Information Technology Agency to begin a phased duplicate-image-replacement initiative that officials say will stretch into 2027. The effort, still in early rollout, covers everything from permit-inspection photographs held by the Department of Building and Safety to aerial survey imagery used by the Bureau of Engineering on projects tied to 2028 Olympic infrastructure corridors.

The timing matters. Los Angeles is under extraordinary pressure to clean up its digital infrastructure before the Olympics, and Mayor Karen Bass's office has separately pushed agencies to digitize housing-emergency records faster as the city tracks roughly 45,000 unhoused residents through shelter-placement systems. Duplicate images clog those workflows, slow case-file retrieval, and — in at least one documented internal audit — caused a Skid Row shelter-bed record to be mis-filed under a duplicate property photograph from a separate Boyle Heights inspection. The ITA flagged the problem in a January 2026 internal review.

The city's primary tool is an AI-assisted deduplication platform piloted first at the Los Angeles County Assessor's Office in Norwalk, which began using similar software in late 2024 to reconcile property imagery across its parcel database. The ITA is now running a parallel track, with the Department of City Planning — headquartered on Spring Street in downtown — serving as the first full agency to migrate under the new protocol. The Southeast Los Angeles district office, which handles high-volume permit photography for neighborhoods including Watts and Florence, is the designated test corridor.

How L.A. Compares to Amsterdam and Seoul

Amsterdam completed a citywide duplicate-image audit of its municipal asset management system in 2023, cutting storage overhead by 31 percent across the Gemeente Amsterdam's digital archive, according to a publicly released report from the city's Chief Information Officer that year. Seoul's Smart City division, operating out of the Digital Innovation Bureau, finished a similar consolidation in 2022 and now runs a real-time deduplication layer across all district-level inspection databases — meaning duplicates are rejected at the point of upload rather than cleaned up retroactively. Los Angeles is still working retroactively.

London's Government Digital Service published benchmarking data in March 2025 showing that cities with populations above four million that had implemented proactive deduplication saved an average of 18 percent annually on cloud storage costs compared with cities still running reactive audits. Los Angeles, with its data spread across Oracle, Salesforce, and legacy on-premise servers at the El Monte data center, faces a harder migration path than Amsterdam or Seoul, both of which had more centralized architectures when they began their projects.

The port is a separate headache. The Port of Los Angeles in San Pedro manages an independent imagery archive for terminal inspections and container-tracking documentation. Port staff have confirmed publicly that the terminal system does not yet communicate with the ITA's deduplication framework, meaning a ship-berth photograph can exist in three separate databases simultaneously — the port's own, the Harbor Department's, and a state-level maritime archive — without any of the three flagging the redundancy.

What Comes Next for City Agencies

The ITA's current project timeline calls for all 14 participating agencies to complete their first-pass deduplication by March 2027 — eight months before the Olympic torch arrives. Agencies that miss that window risk having their imaging budgets flagged during the city controller's annual technology audit, which in 2025 identified digital-asset waste as one of three priority areas citywide.

For residents interacting with city systems — whether filing a building permit in Eagle Rock, submitting wildfire-defensible-space documentation in Tujunga, or checking a case file at the Housing Authority of the City of Los Angeles on South Figueroa Street — the practical effect should eventually be faster record retrieval and fewer instances of mismatched property photographs slowing an inspector's review. City IT staff say the Spring Street pilot will produce a public-facing progress report by October 2026, which will form the basis for the full agency rollout schedule. Amsterdam took two years to get it right. Los Angeles, characteristically, is giving itself less time.
