Kern Valley State Prison

Kern Valley State Prison (KVSP) is state prison for male inmates that is located in Delano, California. It is a Level IV institution that houses 4,600 inmates in four semi-autonomous facilities and two stand-alone Administrative Segregation Units all surrounded by a Lethal Electrified Perimeter Fence. There is also a Level I Minimum Support Facility (MSF) that houses 400 inmates in dorms.

Kern Valley State Prison opened in June 2005 and is adjacent to the North Kern State Prison. It was California's 33rd prison and the last of 20 new prisons to be built over a period of two decades during California's massive prison expansion.

Also known as Delano II, Kern Valley State Prison was designed and built to house a total of 5000 inmates and is a Level I, Level IV prison. KVSP contains a large number of SHU, PHU and Ad-Seg Housing Units and was designed to house the state’s most problematic inmates.

KVSP was designed to be the first fully-programmed Level IV institution in California with a variety of academic and vocational education programs. The goal is to increase an offender’s chances of reentering society successfully.

Getting Approved for a Visit

If you are denied, the prison will send you a letter explaining the reason for disapproval.
