The operating philosophy of the Natrona County Jail (Detention Center) is to provide for community safety, facility security, and the welfare of staff and inmates. In 1996, the Natrona County Jail was established with six housing pods and a bed count of 211. In 2006, the Natrona County Jail completed renovations and added four new housing pods and brought the current bed count to 476.

The Natrona County Jail’s function is to safely and securely detain both pre-trial detainees and sentenced inmates. Although inmates are subject to deprivations resulting merely from confinement, staff understand their role is not to inflict punishment, but to make the inmate’s period of confinement as productive as possible.
