The Main Adult Detention Facility (MADF) was opened in 1991. This “new generation” facility was based on a “direct supervision” design, as opposed to the “linear” design of the County’s earlier jails. Originally designed to hold close to 500 inmates, the facility quickly reached it’s housing capacity and an expansion was opened in 1997 to provide an additional 290 beds. The facility is a medium/maximum security facility, housing both pre-trial and sentenced inmates.

The direct supervision concept at MADF encourages officer contact with inmates and emphasizes the use of interpersonal communication skills. Officers provide a leadership role and make themselves available to inmates by using the new generation/direct supervision model for inmate management.
