A major three-year renovation from 2014 to 2017 added a new housing wing, upgraded security systems with over 200 cameras, and modernized medical services. The jail is operated by the Mason County Sheriff’s Office and serves as the primary correctional facility for Mason County, Washington.

Facility History and Structural Development
Mason County Jail began operations in 1958 as a small, minimum-security lockup designed to hold 45 inmates. Over time, increasing population and legal requirements led to the need for expansion. In 1999, a $2.3 million project added a new cell block, recreation yard, and intake processing area, increasing licensed bed capacity to 104. This upgrade allowed the jail to better manage local arrests and court-ordered detentions. Between 2014 and 2017, the facility underwent a comprehensive internal renovation. During this period, excess inmates were temporarily transferred to neighboring facilities in Lewis County, Nisqually County, and Forks City under inter-agency contracts costing approximately $90,000 per month. The renovation improved living conditions, enhanced safety protocols, and brought the medical triage area up to current state health standards.

The Mason County Jail employs a professional corrections team of 17 full-time staff members. This includes one chief deputy, three shift supervisors, eight correctional officers, two medical personnel, and three administrative staff.

Shift supervisors manage officer rotations and ensure compliance with safety procedures. Correctional officers conduct routine checks, monitor inmate behavior, and respond to emergencies.
