'My History Is Gone': Mission District Families Demand Answers After City Archive Swap Erases Decades of Neighborhood Photos

Sometime between late April and early June, an automated process inside San Francisco's Department of Technology replaced hundreds of photographs stored in the city's public-facing digital archive with duplicate or mismatched images — wiping visual records that community organizations along the Mission and Tenderloin corridors had spent years curating and uploading through the SF Open Data portal. The department confirmed the error in an internal notification circulated to registered data contributors on June 18, but has not yet issued a public statement.

For the families and nonprofits affected, the timing is awful. The city is in the middle of a broader push to digitize neighborhood history as part of the San Francisco Public Library's HistoryRoom digitization initiative, and community groups had been racing to contribute their own materials to that effort. Losing photographs now means losing leverage — and potentially losing the historical record of neighborhoods that have already absorbed decades of displacement.

Valencia Street to Tenderloin: Who Got Hit Hardest

At the Mission Cultural Center for Latino Arts on 24th Street, staff discovered in late June that roughly 40 event photographs uploaded between 2021 and 2024 had been replaced by duplicated stock-style images bearing no relation to the originals. The center has hosted programming in that space since 1977 and relies on its photo archive for grant applications, donor outreach, and community storytelling.

On Turk Street in the Tenderloin, the Faithful Fools Street Ministry — which has documented its outreach work in that neighborhood since the 1990s — found that several years of uploaded images from community dinners and harm-reduction walks had been overwritten. Staff there said they are working with external hard drives to reconstruct what they can, but not all contributors backed up their files before submitting them to the city system, which the Open Data portal's contributor guidelines did not require as a condition of upload.

The Chinatown Community Development Center, based on Powell Street, also reported irregularities in its submitted photo sets, specifically images connected to its Ping Yuen housing complex oral history project, which launched in 2023 with support from the California State Library.

What the Data Actually Shows

San Francisco's Open Data portal currently lists more than 530 active datasets, and the Department of Technology's own documentation shows that image-based assets represent a small but growing share of that total — a category that expanded significantly after the city's 2022 digital equity strategic plan called for richer multimedia representation of underserved neighborhoods. The department has not released a count of how many individual image files were affected by the duplication error, and requests for that figure had not been answered as of press time Friday.

Recovering lost digital files is not cheap or fast. Professional archival recovery services in the Bay Area typically start at around $150 per hour, according to pricing listed publicly by several firms serving the nonprofit sector in San Francisco and Oakland. For a small organization operating on a tight program budget — the kind common among Mission District cultural nonprofits, many of which rely on grants from the San Francisco Arts Commission — even a 10-hour recovery project represents a meaningful expense.

Community members are now being directed to file formal data correction requests through the city's DataSF support desk, a process that ordinarily takes 15 to 30 business days. Several organizations say they have already submitted tickets and are waiting. The Department of Technology has not indicated whether it will offer any expedited review for affected community contributors, or whether it will cover any costs associated with file recovery.

Anyone who uploaded images to the SF Open Data portal between January 2024 and June 2026 should check their contributor dashboard for discrepancies and file a correction request immediately at datasf.org. Organizations that retained original files on local storage should hold those backups and avoid re-uploading until the department clarifies whether the underlying duplication mechanism has been fixed — otherwise, the same error could overwrite restored files a second time.
