Local Inmate Family Councils (IFC's) are a gathering of family and friends of the incarcerated who meet regularly with Wardens to support visiting since keeping strong family connections with loved ones is a powerful rehabilitative tool. These IFC's promote visiting by clarifying rules and regulations as well as discussing health, education, vocational training, packages, books, and related issues. For more information on connecting with a local IFC, please visit the Statewide IFC website.

About California Institution for Men

CIM opened in San Bernardino County in 1941 on 2,500 acres of land. The California Institution for Men (CIM) is a large complex consisting of four separate facilities under the administration of one warden.

Historical Notes:

Dedicated on June 21, 1941, the California Institution for Men was the first major minimum security institution built and operated in the United States. It was the State of California's third correctional institution and was constructed to relieve the overcrowded conditions of San Quentin State Prison (1852) and Folsom State Prison (1881).

CIM was unique in the field of penology because it was known as the "prison without walls." The only "security" fence around the facility units was a five-strand barbwire livestock fence, intended mainly to keep the dairy cows from wandering through the living areas.

CIM has since increased security to meet the challenges a vastly different inmate population requires. While no longer known as "the prison without walls" CIM's Secure Level I Facility A houses the largest Level I inmate population within the California prison system. The CIM I Facility has approximately 2,000 minimum custody level inmates at the facility.

In additional to the CIM I Facility, CIM?s operation includes one reception center, Facility B Reception Center (1951). In August 2010, CIM converted the former Reception Center West facility to a mainline facility known as Facility A, which houses custody level II sensitive needs inmate population. In December 2012 CIM converted Reception Center East facility to a mainline facility know as Facility C. This facility houses custody level-III sensitive needs inmates.
