Marin County Joins CA AG Lawsuit Against Permit-Bypassing Gilroy ICE Facility as Multi-County Coalition Grows

On June 23, 2026, the Marin County Board of Supervisors voted to file an amicus brief (authored by the Public Rights Project) supporting the California Attorney General and Santa Clara County lawsuit challenging a new ICE detention facility near Gilroy that was built without required local review or permitting. Monterey County supervisors had already voted unanimously to join the litigation. The multi-county coalition backs a motion for a preliminary injunction to halt the facility; Marin is separately part of San Francisco v. Trump challenging sanctuary-jurisdiction funding cuts. The Gilroy facility marks ICE detention’s expansion into the Bay Area footprint by bypassing local land-use authority.

This is a multi-county-coalition resistance fight in the detention-pipeline lane, building on Monterey County’s earlier opposition resolution (2026-05-19–monterey-county-resolution-opposing-gilroy-ice-detention-facility) and the secret GSA lease that seeded the facility (2025-01-08–gsa-secret-lease-gilroy-holsclaw-ice-detention-elmwood-capital-ecg6-llc). It parallels the warehouse-conversion litigation in Salt Lake (2026-06-08–salt-lake-city-county-sue-dhs-ice-warehouse-detention-conversion) and the Communities Not Cages mobilization (2026-04-25–communities-not-cages-national-day-of-action-ice-warehouse-detention). The permitting-bypass mechanism — which federal exemption ICE invoked and whether it applies statewide — is the load-bearing open question.
