California State Prison, Solano (SOL) is a male-only state prison located in the city of Vacaville, Solano County, California, adjacent to the California Medical Facility. The facility is also referenced as Solano State Prison, CSP-Solano, and CSP-SOL.[2][3][4]


As of fiscal year 2006/2007, SOL had a total of 1,308 staff and an annual operating budget of $158.4 million.[5] As of February 2011, it had a design capacity of 2,610 but a total institution population of 5,050, for an occupancy rate of 193.5 percent.[6]

SOL's 146 acres (59 ha) include the following facilities, among others:[2]

  • Level II housing: Open dormitories with secure perimeter fences and armed coverage
  • Level III housing: Individual cells, fenced perimeters and armed coverage


The California prison construction boom between 1984 and 2005 was driven by years of increasingly tough anti-crime legislation, and began with the construction of California State Prison, Solano, which opened in August 1984.[7] SOL was overseen by the warden of the California Medical Facility until January 1992, when a separate warden was assigned.[8] By 1998, SOL was so crowded that "emergency triple bunks" were added.[9] A 2001 U.S. District Court ruling and a 2002 U.S. Court of Appeals decision supported the "right of Muslim inmates" at SOL "to attend regular weekly religious services and wear beards in accordance with their faith".[10] In the last year 2008/2009 triple bunking has been removed and the gyms at this time are not holding inmates (August 2009). The inmate population was approximately 5500 in August 2009.
