The prison consists of five facilities: A, B, C, D, and M. Of the five, Facility A, D, and M house Sensitive Needs Yard (SNY)[clarification needed] inmates. The surrounding housing units hold level-4 and level-3 inmates, the two highest security rankings. M yard is a level-1 yard which houses approximately 200 inmates.
The prison had a gymnasium which, due to the prison's over-crowding, at one time had been converted into a dormitory but due to inmate population reductions was shut down around 2008.
The prison also houses an inpatient mental health program, formerly operated under the auspices of the California Department of State Hospitals (Salinas Valley Psychiatric Inpatient Program) to accommodate the psychological needs of inmates.
As of July 31, 2022, SVSP was incarcerating people at 102.5% of its design capacity, with 2,941 occupants.[2]
