SF City Agencies Push to Eliminate Duplicate and Outdated Images From Public Digital Records This Week

San Francisco city agencies moved this week to accelerate a months-long project to identify and replace duplicate images embedded in public databases, permit portals, and municipal websites — a technical housekeeping effort that officials say has direct consequences for how residents access services online. The Department of Technology, which oversees the city's digital infrastructure from its offices on Seventh Street, confirmed the latest phase of the cleanup began July 1.

The timing matters. The city has been overhauling its 311 portal and the SF.gov property information system simultaneously, and duplicate image files — identical or near-identical photographs stored multiple times across disconnected databases — have caused loading failures and search index errors that slowed both platforms. With San Francisco's housing production emergency in full swing, the permit application portal run by the Department of Building Inspection processes hundreds of new submissions weekly, and a cluttered image library has meant some property photos were misfiled against the wrong parcel numbers in the city's assessor records.

What Triggered the Push This Week

The immediate catalyst was a technical audit completed June 27 by the city's Digital Services team, a unit within the Department of Technology that was formally established in 2019. The audit identified more than 14,000 image files across three departmental servers that were exact or near-exact duplicates, consuming an estimated 2.3 terabytes of redundant storage. That figure, drawn from the audit summary circulated to department heads, helped crystallize what had been treated as a low-priority backlog item into an active remediation project with a 90-day deadline.

At the SF Planning Department, which maintains visual records tied to environmental review filings for projects across neighborhoods from the Tenderloin to Visitacion Valley, staff have been manually verifying replacement images for roughly 400 case files flagged by the audit. The Civic Center offices have had two additional contractors on site this week assisting with the verification process. The Department of Building Inspection, headquartered at 49 South Van Ness Avenue, is running a parallel review focused specifically on permit records tied to accessory dwelling unit applications, which surged after the city's 2023 ADU streamlining ordinance took effect.

The work connects to a broader pattern affecting cities that digitized large volumes of paper records quickly during the pandemic. San Francisco moved aggressively between 2020 and 2022 to scan legacy permit files and zoning records, uploading images in bulk without a standardized deduplication protocol. The result was a sprawling archive with significant overlap. The city's contract with its primary cloud storage vendor, renewed in March 2026, includes a tiered pricing structure that charges incrementally above a 10-terabyte threshold — meaning the redundant files were generating real ongoing costs, not merely occupying abstract digital space.

What Residents Should Know Right Now

Property owners checking permit status or pulling historical records through the SF.gov portal may notice some image attachments temporarily unavailable on specific case files while replacement images are verified and re-uploaded. The Department of Building Inspection has posted a notice on its public-facing portal advising applicants that processing delays of up to three business days may occur for files under active image review. Residents filing new permit applications through the Permit Center at 49 South Van Ness should not be affected — the temporary holds apply only to records created before January 2023.

The SF Public Library's digital collections, maintained separately through its branch system and the main branch on Larkin Street, are outside the scope of this particular cleanup but the library's own digital archivist team confirmed it is monitoring the city's methodology for possible adoption in its own image catalogues, which include photographs from the San Francisco History Center collection.

The 90-day remediation window runs through late September. The Digital Services team has committed to a public progress dashboard, expected to go live on SF.gov by July 18, that will track the number of duplicate files resolved, storage recovered, and departments still pending review. For residents, the practical upshot is a faster, more reliable portal — but not quite yet.
