Sacramento County sits at the heart of California’s capital region, and its system of regional governance shapes everything from public safety and transportation to land use and social services. Understanding how that system works helps residents, businesses, and community partners know where to turn and how to get involved.
Charter County and Elected Leadership
Sacramento County operates under a charter form of government, which functions like a local constitution adopted under California law. For a broader overview of how charter and general law counties function across the state, the California State Association of Counties offers a detailed explanation of county structure on its website. The charter defines how power is divided between elected officials, the County Executive, and the departments that deliver day‑to‑day services.
At the core is a five‑member Board of Supervisors, each elected from one of five supervisorial districts for staggered four‑year terms. Supervisors are chosen on a nonpartisan basis, and district boundaries are adjusted after each federal census to keep populations roughly equal. Countywide elected offices also include the Sheriff, District Attorney, and Assessor, who oversee law enforcement, prosecutions, and property valuation across the region.
Board of Supervisors: Policy and Regional Role
The Board of Supervisors serves as the county’s main legislative body and also exercises executive and quasi‑judicial powers. As a legislative authority, the Board adopts ordinances, establishes programs, levies certain local taxes, appropriates funds, and sets broad policy direction for county departments.
In its executive role, the Board directs the County Executive and can organize departments or create new offices, boards, and commissions by ordinance to improve service delivery. Acting in a quasi‑judicial capacity, the Board often serves as the final local appeal body for land‑use and planning decisions in the unincorporated area.
Supervisors also sit on numerous intergovernmental boards and special districts, giving Sacramento County a voice in regional transit, air quality, water, and other multi‑jurisdictional issues.
County Executive and Organizational Structure
While policy is set by the Board, the County Executive manages the day‑to‑day operations of county government. Appointed by the Board, the County Executive coordinates dozens of departments and offices that deliver everything from health and human services to public works and internal administration.
County operations are commonly grouped into three broad categories: areawide services, municipal services, and administrative services. Areawide services—such as elections, property assessment, and county jails—serve all residents within the county’s boundaries, regardless of city limits.
Municipal services are tailored to the unincorporated areas, where the county acts as the local city government for functions like zoning, building permits, and code enforcement. Administrative services support employees and internal functions, including finance, human resources, and information technology.
Serving Cities and Unincorporated Communities
Sacramento County encompasses seven incorporated cities, including Sacramento, Elk Grove, Citrus Heights, Rancho Cordova, Folsom, Galt, and Isleton, alongside extensive unincorporated communities such as Arden‑Arcade and Fair Oaks. In incorporated cities, city governments handle their own municipal services, while the county continues to provide areawide functions like courts, jails, social services, and public health.
In unincorporated areas, however, the county is the primary local government for land use, local road maintenance, and many neighborhood‑level services. Residents in these communities rely on county departments for building permits, planning approvals, business licensing in the unincorporated area, and enforcement of county codes.
This dual role—regional provider for all and city‑equivalent for unincorporated territory—is a defining feature of Sacramento County’s governance model.
Key Regional Services and Infrastructure
A wide range of departments and partner agencies deliver services that underpin daily life and economic activity across Sacramento County.
Public safety
The Sheriff’s Office provides law enforcement in unincorporated areas and operates county jails, while the District Attorney prosecutes criminal cases countywide.
Elections and records
County offices manage voter registration, elections administration, vital records, and property records for the entire county.
Community development
Through Community Development and Planning and Environmental Review, the county oversees zoning, subdivision approvals, environmental review, and long‑range land‑use planning in unincorporated communities.
Building and permitting
The county’s Building Permits and Inspection services handle plan review and field inspections for private development in unincorporated Sacramento County.
Essential utilities are also managed or coordinated at the regional level. The Sacramento Area Sewer District provides sewer service to more than one million people, including the unincorporated county and several cities. Its governance and representation model is described on the district’s Board of Directors page.
The Sacramento County Water Agency delivers drinking water to tens of thousands of customers across multiple service areas in unincorporated communities and in cities such as Elk Grove and Rancho Cordova. Together, these systems support growth, protect public health, and require close coordination with incorporated cities and special districts.
Health, Human, and Developmental Services
Beyond infrastructure, Sacramento County plays a central role in health and human services for vulnerable residents. County departments administer public health programs, behavioral health and substance use services, and social services including child welfare, adult protective services, and public assistance.
These services are generally countywide in scope, reflecting the state’s reliance on counties as the primary local arm for many health and social safety‑net programs. For individuals with intellectual and developmental disabilities, the state’s Department of Developmental Services contracts with regional centers such as Alta California Regional Center to coordinate lifelong supports.
While regional centers are state‑funded nonprofits rather than county departments, they work closely with Sacramento County agencies, schools, and community organizations to connect residents with housing, employment, and clinical services.
Public Engagement and Regional Collaboration
Public participation is built into Sacramento County’s governance framework through Board of Supervisors meetings, advisory boards, commissions, and direct constituent services. Residents can comment on proposed ordinances, budget decisions, and land‑use changes, or seek assistance through the county’s public information and service centers.
Because regional issues—such as air quality, homelessness, transportation, and flood protection—cross city boundaries, Sacramento County also collaborates with cities, regional transit authorities, joint powers authorities, and neighboring counties. At the statewide level, the California State Association of Counties provides advocacy and policy support that shapes how counties like Sacramento address these regional challenges.
By combining a charter‑based county structure with extensive intergovernmental partnerships, Sacramento County’s system of regional governance aims to balance local neighborhood needs with countywide and multi‑county priorities.
