About Madison County Sheriff's Department
The Madison County Detention Facility is split into three locations, the Main Facility at 815 Wheeler Avenue, Annex 1 located on Fiber Street adjacent to the Main Facility, and the Madison County Courthouse Facility. The City of Huntsville, the Madison County Commission, and the Madison County Sheriff's Office, in 2002, entered into an Intergovernmental agreement releasing control of the Huntsville City Jail to the Sheriff's Office. This agreement also required that the City of Huntsville build an additional facility adjacent to the existing main facility. Under terms of the agreement, the Sheriff's Office, in 2003, assumed the responsibility of housing all persons arrested by the Madison County Sheriff's Office, the Huntsville Police Department, the Alabama State Troopers, the smaller municipalities in Madison County, and the temporary housing of other prisoners for law enforcement agencies, primarily those of a federal nature.
