Jail Operations

jail_frontThe Mason County Sheriffs Office Corrections Division provides jail services for all law enforcement agencies in Mason County. The jail facility is located adjacent to the County Courthouse in Shelton, Washington. The Mason County Jail opened its doors in 1986 to less than 45 inmates. Today, the jail has housed as many as 150 inmates. The latest addition in the jail is the Direct Supervision Unit which opened in 2005 and uses about 20 inmates upstairs and 24 downstairs. The Staff at the Mason County Jail consists of the Jail Administrator, Chief Kevin Hanson. Four Sergeants; Twenty-Nine Officers; Two Cooks; Medical Staff; One Mental Health Professional and One Jail Clerk. The goal of the Mason County Jail is to provide safe custody, decent living conditions, fair treatment, and the protection of constitutional rights for all persons confined therein. 


We strive to maintain effective custody and control of offenders; maintain a healthy, safe, and secure environment for staff and inmates; and provide quality programs to inmates so they will have opportunities to learn more responsible behavior and increase their chance of returning to the community as law-abiding citizens.

Programs Available to our inmates:

  • GED Classes
  • Drug and Alcohol Classes
  • Get Employed Today Program
  • DUI Alternative to Jail Program

The jail has a Litter Crew comprised of low-risk offenders/Trusties that help keep our community clean, as well as a Conservation Crew.
