Palo Alto is set to become the latest Bay Area city to put a legal barrier between itself and new federal immigration detention facilities. City leaders will consider a one-year moratorium on new and expanded ICE detention facilities at the City Council's October 26 meeting, Palo Alto Online reported on October 20, 2026.

The proposal would prevent the use of any public or private property within Palo Alto's city limits for detention or holding facilities, a category the draft ordinance defines to include jails, prisons and processing facilities, according to Palo Alto Online. The language follows similar moratorium provisions recently adopted in nearby Santa Clara County cities such as San Jose, Los Altos and Gilroy.

The regional pattern is well documented. The Mountain View City Council voted unanimously on October 13 to adopt a 45-day urgency moratorium on applications for detention, custodial or processing facilities, the Mountain View Voice reported, in a step the San Francisco Inquirer and the Stanford Chronicle also covered. Gilroy's council unanimously approved its own 45-day ban on October 5, extendable to a total of two years, San Jose Spotlight reported. Congressmembers Sam Liccardo and Zoe Lofgren publicly welcomed the Gilroy and Mountain View actions on October 16.

Behind the wave of moratoriums is a single contested project: earlier this year, San Jose Spotlight reported, the federal government began building an ICE detention facility in unincorporated Santa Clara County near Gilroy without notifying local officials. Santa Clara County and California Attorney General Rob Bonta sued, Palo Alto backed the county's lawsuit, and in September a federal judge — U.S. District Judge Eumi K. Lee, in County of Santa Clara v. ICE, No. 26-cv-05604 — granted a preliminary injunction pausing construction while the environmental-review case proceeds.

Palo Alto Online noted the city has joined several lawsuits in recent months against the federal government over aggressive immigration enforcement, and that its police department already prohibits officers from working with ICE or asking about a person's immigration status for the purpose of making an arrest. No vote has been taken yet in Palo Alto — the October 26 discussion is the next step, and the moratorium would only take effect if the council adopts it. For the large immigrant and Punjabi diaspora communities across the South Bay and Silicon Valley, the decision will determine whether a detention facility could be proposed inside Palo Alto at all over the next year.
