Community Service Unit

Mission Statement

It is the mission of the CSU to work with the Sheriff’s Office to help make Tuolumne County a safer and more enjoyable place to live, work, and visit.


Tuolumne County encompasses 2,293 square miles of territory. The ability of the Sheriff’s Office to provide law enforcement services over such a wide area is severely limited. The county continues to grow in population and law enforcement needs. The ability of the Sheriff’s Office to meet the rising need for service has become more difficult with the current budget limitations.

The increased need for services by the Sheriff’s Office requires increased personnel and added expenditure of public funds, which are not always available. A partial answer to this problem is the utilization of the volunteer pool of talent and experience in the community.

CSU Volunteer Requirements

*Minimum 18 Years of age

*Must maintain professional and private life in a way that exemplifies integrity, trust, and morality as a representative of the Tuolumne County Sheriff's Office
