The Fourth Avenue Jail opened in April 2005. This state of the art facility is considered to be one of the most secure and technologically advanced facilities in the nation. This facility was part of the largest county jail expansion project in the history of the nation, supported overwhelmingly by the taxpayers of Maricopa County.

Fourth Avenue has a capacity of 2,064 beds of which 288 are specifically designed to house the highest security level inmate in the system. The Fourth Avenue Jail was designed first and foremost with the interest of public safety in mind, following Sheriff Joe Arpaio’s philosophy of remaining tough on crime.

The Fourth Avenue Jail features user friendly video visitation for the general public. This facility also maintains a fully staffed and equipped medical and dental clinic. In addition, inmates are offered educational and religious services in the chapel and classrooms within the facility.
