The Board of Supervisors is the governing body of the County and a number of special districts. Within the limits of state law and county charter, the Board is empowered to adopt ordinances, establish programs, levy taxes, appropriate funds, appoint certain officials, and zone property in the unincorporated area. In addition, members of the Board represent the County on numerous intergovernmental bodies.
The five members of the Board are elected on a non-partisan basis to serve four-year terms and there is no limit on the terms that members can serve. Each is elected from one of the five supervisorial districts of the County. Supervisors from Districts 1, 2 and 5 are elected in gubernatorial election years (2006, 2010, etc.) while supervisors from Districts 3 and 4 are elected in presidential election years (2004, 2008, etc.). District boundaries are adjusted after every federal census to equalize district population.
- District 1 is represented by Supervisor Phil Serna who was elected in June of 2010. This district encompasses much of the northwestern portion of the County, including Sacramento International Airport and McClellan Business Park.
- District 2 is represented by Patrick Kennedy, who was elected June 2014. Supervisor Kennedy is a fourth generation Sacramentan and has served on local boards, commissions, associations and directed statewide initiatives. His district covers much of the City of Sacramento.
- District 3 is represented by Rich Desmond, who was elected in 2020. District 3 includes the urban unincorporated communities of Arden Arcade, Carmichael, Fair Oaks, Foothill Farms, and North Highlands. It also includes the College-Glen and Campus Commons neighborhoods in the City of Sacramento.

- District 5 is represented by Pat Hume, the newest member of the Board who was appointed in 2022. Supervisor Hume’s district encompasses nearly 700 miles of the County, including the cities of Elk Grove, Rancho Cordova, Isleton, Galt and portions of the City of Sacramento.
The Board utilizes many citizen committees and commissions to aid them in governing county operations. Vacancies are noticed on the Board meeting agendas and posted at the main library and all branch libraries. Applications may be obtained from the Clerk of the Board or any library.
