The Ancillary Services Division consists of two sections, the Medical Services Section and the Hearing Services Section, and is commanded by a Detention Officer Captain.

Medical Services Section
The Medical Services Section is commanded by a Detention Officer Lieutenant, and is responsible for coordinating all medical services within the Maricopa County Jail System with Correctional Health Services (CHS).

The Medical Services Section is comprised of two Correctional Psychiatric Units that are licensed by the State of Arizona, and a twenty-three bed Infirmary. Detention and medical personnel, who work very closely to provide optimum care for the inmates, staff all of these units.

The most chronically ill male inmates and those requiring a high level of security are housed in the Madison Unit I, House 6-3. Stabilized males and all females are housed within Durango Jail Unit II, House D-2. The Infirmary, a licensed hospital unit, is located on Level 4 of the Madison Street Jail, and cares for those inmates that are medically not stable enough to be placed in the general jail population.

Hearing Section
A Detention Officer Sergeant commands the Hearing Section. The Sergeant is assisted by six specially trained and experienced detention officers, and is responsible for reviewing the grievances and complaints submitted by the inmates of the Maricopa County Jail System. The Hearing Officers are also responsible for reviewing inmate disciplinary measures, to make sure that the discipline is fair and appropriate, and that inmates are given a chance to be heard in the process.

Inmates may file grievances on any of the conditions of their incarceration. When they do file grievances, it is most commonly on conditions such as their food, where they are housed, what they can receive from the Commissary, their medical care, or what they perceive as restrictive jail rules.

When inmates receive sanctions for disobedience of jail rules, or "discipline", it usually means that they will be placed in restrictive custody for a given number of hours or days, depending upon the severity of the infraction. When they are placed in restrictive custody, inmates may not be able to make phone calls, have visitors, or attend programs. They may also be restricted to their own cell for longer hours in the day, and not be able to socialize with other inmates in the dayroom areas.

The Hearing Section is a multi-functional unit dealing with all aspects of inmate discipline and complaints. The Hearing Officers must remain unbiased, and they must make reasonable determinations on issues ranging from implementing sanctions on inmate disciplinary issues to providing avenues to resolve inmate complaints. The Section ensures that inmates retain their rights of due process while in custody of the Maricopa County Jail System. This helps to extend an open line of communication between inmates and staff, as well as between the various Bureaus and staff members, including the Legal Services Division, Correctional Health Services, Food Services, and Religious Services.
