Arizona State Prison Complex-YUMA HistoryThe Arizona State Prison Complex - Yuma has come a long way since the Yuma Territorial Prison that was operational just a mere 100 years ago, paved the way for the Arizona Department of Corrections as we know it today.

The Arizona State Prison, Cocopah Unit, built in 1986, began as a 250 bed minimum security facility on 33 acres. Its status, upon completion of construction, was unique - particularly in a prison system that was overcrowded. After all activation processes were developed and readied for occupation, consideration was given to selling the facility to the Federal government. At that time, the prison was put in mothballs.
In 1987, it reopened, and has continued to expand ever since. Cocopah Unit is a minimum custody unit that employs 64 staff and is residence to an average of 392 inmates in its general population.
In November 1995, the stand-alone Arizona State Prison became Arizona State Prison Complex - Yuma.
