Ada County Jail

The Ada County Jail was built in 1977 when the Ada County-Boise City Public Safety Building first opened. The jail was originally built to hold a maximum of 160 inmates, plus 32 work release prisoners.
The jail has been expanded several times since then. Today, the total inmate capacity is 1224.

Inmate Classification

All inmates at the Ada County Jail are classified using a specific system which is basically a risk assessment. By classifying all inmates, security of other inmates and jail staff is greatly increased. To classify an inmate, a team of officers researches the inmate’s past and criminal history. They also consider the inmate’s past and present behavior when in custody. Mental or physical disabilities are also taken into consideration when determining appropriate housing.

Inmates are assigned a security risk level, or classification, ranging from minimum to maximum. Minimum security inmates enjoy the highest level of benefits and privileges. Medium security inmates may also have certain privileges, like dormitory housing and access to programs. Inmates who are classified as maximum risk do not have access to most programs or privileges.

Inmate Housing

There are different types of inmate supervision used inside the Ada County Jail. One is called Close Custody Unit (CCU). CCU can house a total of 130 inmates. This is the traditional cell structure where more violent offenders or those inmates who cannot be mixed with the general population are housed.
Other inmates live under what is referred to as Direct Supervision. Their housing is set up in “pods”. Within each pod are dorms. Each male dorm holds 92 inmates. Each female dorm houses 56. In dorms, there are no single cells. Inmates have their own beds and they all share a common area. Generally, one deputy is able to supervise an entire dorm.

Release From Jail

There are two main ways to be released from jail following an arrest in Ada County: pay a surety bond associated with each criminal charge, or have a 4th Judicial District Judge order a release.

If an inmate has a bond attached to an arrest warrant or if a judge sets bond for a criminal charge in court, that inmate can be bailed out of the Ada County Jail for the amount of the bond and an additional $25 administration fee. For inmates with multiple charges, separate bonds and $25 fees must be paid for each charge. If a judge combines multiple charges under one single case number, a single $25 administrative fee covers the bonds associated with those charges.

Bonds must be paid in cash; or with a cashier’s check or money order; or by a bail bond service. Personal checks and credit cards are not permitted. Additionally, a fee of $25 must accompany each bond.

For example, if someone is being held in the jail on separate misdemeanor charges of petit theft and failure to appear, with bonds of $500 and $200, whoever wants to bond that inmate out would have to bring $750 in cash; or separate cashiers checks or money orders of $700 and $50; or hire a professional bail bondsman to pay the bond to get that inmate out of jail.

The Ada County Jail has an ATM machine in the lobby. Cash withdrawal limits can vary, depending on what bank the customer has an account with.

To find out if an inmate qualifies for a bond release, look up the name at  Ada County Inmates The amount for bond is listed on the “Bail” column to the right of each charge, with a bail total on the bottom.

People must pay in person at the counter in the lobby of the main Ada County Sheriff’s Office building at 7200 Barrister Drive. The jail is located in the same campus.
