San Francisco, CA — Mayor Lurie's Privacy Protections for Public Safety Cameras: SFPD License Plate Reader Searches Limited to 30 Days, Monthly Log Reviews, DPA Audits, Immigration-Use Ban (September 2026)
San Francisco, CA · Office of the Mayor, City and County of San Francisco, press release on public safety camera privacy protections (Sept. 29, 2026)

Status
Enacted (not yet in effect)
Applies to
San Francisco Police Department personnel; agencies with ALPR data-sharing authorization
Enforced by
San Francisco Police Department; Department of Police Accountability (audits)

On September 29, 2026, Mayor Daniel Lurie announced tighter rules for how San Francisco police use license plate reader data. Officers can now search plate-reader data for investigations only during the first 30 days after it is captured, down from 12 months, and each search must be tied to a dispatch or incident number. SFPD's data is to be removed from the vendor's platform after 30 days, federal agencies get no direct access, and use for civil immigration enforcement, tracking reproductive or gender-affirming care, or monitoring First Amendment activity is prohibited. SFPD will review system-use logs monthly and will ask the Department of Police Accountability to conduct regular independent audits; personnel who violate the rules face discipline up to termination. The Electronic Frontier Foundation criticized the package as weak because it does not require a warrant or set a deletion deadline.

Who is protected: People whose vehicles are captured by San Francisco police license plate readers

Legal detail

Administrative policy announced by the Mayor's Office Sept. 29, 2026 (sf.gov press release); no Board of Supervisors ordinance is cited. Per the release: (1) investigative searches of ALPR data permitted 'only during the first 30 days after the data is captured, down from 12 months' — an ACCESS limit, not a stated retention/deletion period; searches require a CAD or incident number; (2) SFPD ALPR data removed from the vendor platform after 30 days; exclusive local control; no direct federal agency access; (3) monthly system-use log reviews; SFPD will ask the Department of Police Accountability to conduct regular independent audits; violators subject to discipline up to and including termination; (4) prohibited uses: civil immigration enforcement, monitoring based on reproductive or gender-affirming care, First Amendment-protected activity; (5) agency-by-agency sharing authorization maintained; external agencies may not search on behalf of unauthorized entities; (6) Mayor to work with Assemblymember Matt Haney and DA Brooke Jenkins on state legislation increasing penalties for misuse or unauthorized disclosure of ALPR data (not yet introduced per sources). The release does not name the vendor or state an effective date. EFF (Sept. 29) says the policy lacks a warrant requirement, a deletion deadline, and documentation of search reasons. NOT ESTABLISHED: formal instrument (directive/General Order), effective date.
