As of Fiscal Year 2006/2007, SAC had a total of 1,585 staff and an annual operating budget of $187 million. As of September 2007, it had a design capacity of 1,788 but a total institution population of 3,260, for an occupancy rate of 182.3 percent. As of April 30, 2020, SAC was incarcerating people at 129.3% of its design capacity, with 2,363 occupants. SAC's facilities include:
Level I housing – Open dormitories without a secure perimeter
Level IV housing – Cells, fenced or walled perimeters, electronic security, more staff and armed officers both inside and outside the installation
The prison has "three similar but separate self-contained facilities... each eight housing blocks and a recreation yard." The housing blocks "are partitioned into three separate, self-contained sections forming a 180 degree half circle." The "180" design is considered the "most secure prison design" because it "gives control-booth officers a straight-on look at prisoners." In contrast, the "270" design "with portions of the house reaching back behind the blind side of the booth" is considered less secure.
History
When they were built, the maximum-security buildings of what is now SAC were considered an "addition" to FSP. The first FSP inmates were transferred to the addition on October 1, 1986. In 1986, the prison was administered by the Folsom warden and was called New Folsom. In October 1992, its name was changed to CSP-Sacramento, and was administered as a separate prison with its own warden." Erik Menendez was sent to SAC with a sentence of "life in prison without parole" in September 1996. He was married there in June 1999. A major fight involving about 150 inmates occurred at the prison in September 1996, with 13 inmates injured and 17 shots fired by officers. Local officials opposed a 2001 law and two 2005 bills that might eventually have led to a transfer of death row operations from San Quentin State Prison to SAC. On May 20, 2011, a large-scale riot broke out at the prison. Prison spokesman Sgt. Tony Quinn said the incident started just after 10 a.m. when two inmates began fighting with each other. The fight then took over the yard with approximately 150 inmates getting involved. At least two inmates were stabbed multiple times and were taken to an outside hospital for treatment. On August 12, 2015, a riot occurred at SAC in which Hugo Pinell was killed.
