Facility History and Modern Upgrades
The Mason County Jail was first built in 1958 as a 45-bed minimum-security lockup. Over time, growing population and legal requirements led to a major expansion in 1999. A $2.3 million project added a new cell block, recreation yard, and intake processing area, increasing capacity to 104 beds. In 2014, the jail began a three-year internal renovation to meet updated safety and health standards. The project finished in March 2017 and included a new housing wing, over 200 upgraded security cameras, and a refurbished medical triage area. These improvements allowed the facility to comply with state staffing ratios and health codes. The upgrades also enhanced monitoring capabilities and inmate living conditions. Today, the jail maintains a secure, humane environment for both staff and detainees.
