Los Angeles County is in the process of building two new correctional facilities: 1) the Mira Loma Women's Correctional Center (projected completion: 2022) at the location of the closed Mira Loma jail facility in Lancaster (with 1,604 beds) and 2) the Consolidated Correctional Treatment Facility or CCTF (projected completion: 2028) next to the Twin Towers Correctional Facility to replace Men's Central Jail and offer expanded facilities for the increasing number of mentally ill inmates (total 3,885 beds).

Medical Services Bureau of the Los Angeles County Sheriff's Department is the largest correctional medical service provider in the world.

North County Correctional Facility was once also known as "SuperMax."

The facilities of the Pitchess Detention Center in Castaic were once known as Wayside Honor Rancho and was established as a minimum security facility in 1938 where inmates worked in a farm setting. The farm setting for the jail closed in 1992.

Until 2012, the Mira Loma Detention Facility was contracted by U.S. Immigration and Customs Enforcement (ICE) to house non-U.S. citizens detained for violations of U.S. immigration laws. It was the largest detention facility operated by U.S. immigration authorities in California. The facility operated as a regular county jail except that persons housed there are federal immigration detainees. Detainees were citizens of any one of more than sixty different countries and remained in detention at the facility until their cases were decided in U.S. Immigration Courts. ICE personnel assigned to Mira Loma handled all detainee transport, releasing, tracking and removal (or deportation). Los Angeles County Sheriff deputies and custody assistants only worked in Executive Office of Immigration Review courtrooms at the facility.
