Visitation Information

Schedule a Visit - GettingOut

  • Inmate visitation will be facilitated through video only.

  • Inmates will be responsible for scheduling visitation.

Inmates must submit a list of people they want on their visitation list. Inmates may list up to eight people on that list, however, they are allowed only 3 visitors during visitation. Minors are included in this number. All minors must be accompanied by an adult. After the inmate submits their list, it takes up to one week for the visitors to be approved and added into the computer. The inmate picks the time and day of the week that they want each of their visitors to see them. The inmate is responsible for notifying their visitor (s) of their assigned day and time. If the inmate wants his or her pastor/priest (i.e. professional visitors) to come see them, they must be added to their visitation list as well.
