Thousand Oaks follows California's statewide sanctuary policy under SB 54, the California Values Act, which limits local law enforcement cooperation with federal immigration authorities. The City has no separate sanctuary ordinance.
Thousand Oaks contracts law enforcement through the Ventura County Sheriff's Office, which complies with California Government Code §7284 et seq. (SB 54, the California Values Act of 2017). State law bars local police from using personnel or resources to investigate, detain, or arrest persons for immigration enforcement, transferring people to ICE custody without a judicial warrant, or honoring civil detainers, with narrow carve-outs for serious or violent felony convictions. The Sheriff may notify ICE before releasing inmates with qualifying convictions. The City Council has not passed a separate sanctuary or anti-sanctuary ordinance, so state law controls citywide.
Compliance is monitored by the California Attorney General. Local officers acting outside SB 54's permitted exceptions risk civil liability and AG enforcement action.
