Built in 2004, the Kinney County Detention Center is located 1.3 miles south on Ranch Road, in Kinney County, south Texas. The Texas Department of Health, the Fire Marshals Service, and the United States Marshals Service inspect the facility annually.

CEC began management of the Detention Center in 2007 under an agreement with the United States Marshals and the Kinney County Commissioners Court. In addition to jail/detention management services, CEC provides medical and dental services to the inmates, and use of a law library. There is also a volunteer religious services program and a volunteer work program that includes food service, and laundry. Indoor and Outdoor Recreation is offered to the population, as well as law library services, barber services, and an in-cell art program.

Staff from the facility participate regularly in volunteer activities throughout the community including Relay for Life and the annual Livestock show events.
