The ASPC-Douglas, adjacent to the Bisbee-Douglas airport, first opened as the Cochise Correctional Training Facility early in 1984.
Due to prison overcrowding the Gila unit was built with portable modular housing.
ASPC-Douglas has an inmate capacity of approximately 2,148 in 5 housing units at security levels 2, 3 and 5.
The ADC uses a score classification system to assess inmates appropriate custody and security level placement.
ASPC-Douglas is a modern, medium to high security prison.
