Palo Alto's City Council adopted a one-year moratorium on new detention and custodial facilities on Monday, October 26, 2026, according to Palo Alto Online, which reported the adoption on October 27, calling it a move to protect vulnerable community members. Wisevoter's October 27 report on the same decision also records the October 26 adoption date and the one-year term.

The ordinance, as described in Palo Alto Online's earlier council preview, would prevent the use of any public or private property within city limits for detention or holding facilities, including jails, prisons and processing facilities. It follows similar moratoriums recently established in nearby Santa Clara County cities such as San Jose, Los Altos and Gilroy, and a temporary moratorium voted in Mountain View.

City staff said the moratorium is forward-looking and would not apply to existing custodial facilities such as holding areas in the Public Safety Building or the Superior Court building, and that it expires on its own terms unless the council extends it. The policy will go to the Planning and Transportation Commission for further analysis before the city pursues a permanent ordinance, according to the October 27 reporting.

The debate follows a federal plan to expand immigration detention capacity and a September federal court pause on construction of a detention facility in unincorporated Santa Clara County, which Palo Alto Online reported the city had backed the county's lawsuit over. Palo Alto police already prohibit officers from working with ICE or asking about immigration status for the purpose of making an arrest, the outlet said.
