California’s Shadowy ICE Holding Rooms Detained at Least 17,351 People Last Year

During the first year of the Trump administration's second term, at least 140,000 people nationwide were detained in these rooms—a steep jump from the 80,000 people held from September 2023 to the end of Biden's term.

U.S. Immigration and Customs Enforcement operates 14 holding rooms across California that function like unofficial detention facilities, according to data obtained through the Freedom of Information Act by the Deportation Data Project and analyzed by Colorado Times Recorder. 

Across the nation, ICE uses a total of 170 such holding rooms, according to the Colorado Times Recorder. 

Holding rooms have been used since 2011, typically as temporary holding facilities for people made to wait for transport to detention centers. A waiver issued by the Department of Homeland Security in June extended the time limit for detentions in hold rooms to be increased from twelve hours to three days, with an exception for rooms located in detention centers, which remain at a twelve-hour limit.

Holding rooms operate with different standards than detention centers and are not required to have beds or toilets. The rooms in these facilities are described as small, concrete spaces, lacking privacy, and holding multiple people, as reported by The Guardian
