San Jose FAQ
Can SJPD share my plate data with federal immigration?
No. The California Values Act (SB-54) bars state and local agencies from sharing ALPR reads with federal immigration authorities for civil enforcement. SJPD's ALPR policy explicitly prohibits ICE access and is audited annually for compliance.
How long does SJPD keep ALPR reads?
SJPD's published policy sets a fixed retention period (commonly one year for non-investigatory data; longer if linked to an active case). Civil Code §1798.90.51 requires written justification for the retention period in the agency's posted ALPR policy.
Are private ALPRs (HOAs, businesses) regulated?
Yes. SB-34 also covers private operators of ALPR systems. They must protect data, post privacy policies, and face civil liability under Civil Code §1798.90.54 for breaches and misuse. HOAs sharing data with police should consult counsel on third-party-doctrine issues.
Sunnyvale FAQ
Can my HOA install ALPR cameras at the entrance?
Yes, but the HOA must publish an SB-34-compliant usage and privacy policy, restrict access, set a retention period, and avoid sharing plate data with civil immigration authorities under the County sanctuary policy.
How long does the Sheriff keep ALPR data?
Per the Sheriff's published policy, non-hit ALPR records are retained for a limited period defined in the policy and then purged. Hits associated with active investigations are retained per the case-management retention schedule.
