California Government Structure
California's government operates under the California Constitution, originally adopted in 1879 and extensively amended through more than 500 amendments since its ratification. The Constitution establishes a republican form of government with three co-equal branches -- executive, legislative, and judicial -- and provides for a system of local government comprising 58 counties and more than 480 incorporated cities. Uniquely among American states, California's Constitution also enshrines an extensive system of direct democracy, including the initiative, referendum, and recall processes, which give voters the power to enact laws, reject legislation, and remove elected officials outside of regular elections.
The state capital is Sacramento, where the Capitol building -- completed in 1874 and expanded with a modern annex -- houses the Governor's office and the chambers of the Legislature. California's government is one of the largest in the United States, employing approximately 230,000 state workers across dozens of departments, agencies, and commissions that administer programs ranging from transportation and education to environmental protection and professional licensing.
Executive Branch
The executive branch of California government is headed by the Governor, who is elected statewide to a four-year term and may serve a maximum of two terms. The Governor serves as commander-in-chief of the state militia, has the authority to sign or veto legislation passed by the Legislature (including a line-item veto on appropriations bills), makes appointments to state boards, commissions, and the judiciary, and issues executive orders. The Governor also has the power to grant reprieves, pardons, and commutations of criminal sentences, subject to certain constitutional limitations.
California elects seven additional statewide constitutional officers, each serving four-year terms: the Lieutenant Governor (who presides over the State Senate and succeeds the Governor in case of vacancy), the Attorney General (who serves as the state's chief law enforcement officer and leads the Department of Justice), the Secretary of State (who oversees elections, business filings, and the state archives), the State Treasurer (who manages the state's investments and debt issuance), the State Controller (who serves as the state's chief fiscal officer and auditor), the Insurance Commissioner (who regulates the insurance industry), and the Superintendent of Public Instruction (who leads the Department of Education, the only nonpartisan statewide executive office).
The executive branch includes more than 200 state agencies, departments, boards, and commissions organized under several super-agencies: the Government Operations Agency, the Health and Human Services Agency, the Natural Resources Agency, the Business, Consumer Services, and Housing Agency, the California Environmental Protection Agency, the Labor and Workforce Development Agency, the Transportation Agency, and the California State Transportation Agency. Notable regulatory bodies include the Contractors State License Board (which regulates the construction industry), the California Public Utilities Commission (which regulates investor-owned utilities and telecommunications), and the California Coastal Commission (which regulates land use along the coast).
Legislative Branch
The California State Legislature is a bicameral body consisting of the State Senate and the State Assembly. The Senate has 40 members, each representing approximately 990,000 constituents, who serve four-year terms with a limit of two terms (under the reforms adopted by voters in 2012, which replaced the previous stricter term limits). The Assembly has 80 members, each representing approximately 495,000 constituents, who serve two-year terms with a limit of six terms. Legislative sessions run in two-year cycles, with annual sessions beginning on the first Monday in December of even-numbered years.
The Legislature considers approximately 5,000 to 6,000 bills in each two-year session, covering every aspect of state policy. Bills require a simple majority vote for passage in both chambers, except for urgency statutes (which take effect immediately rather than on January 1 of the following year), tax increases, and constitutional amendments, which require a two-thirds supermajority. Constitutional amendments passed by the Legislature must also be approved by voters at a subsequent election. The Legislature also has the power to place bond measures on the ballot for voter approval, a mechanism that has been used extensively to fund infrastructure projects including transportation, water, education, and housing.
The Legislature exercises oversight of the executive branch through its committee system, budgetary authority, and the power of confirmation over certain gubernatorial appointments. The Legislative Analyst's Office (LAO), a nonpartisan fiscal and policy advisory office, provides independent analysis of the state budget and policy proposals, serving a role analogous to the Congressional Budget Office at the federal level.
Judicial Branch
California's judicial branch is the largest court system in the United States, serving the legal needs of nearly 39.5 million residents. The system handles approximately 5 million cases annually across three levels of courts, employing nearly 2,000 judicial officers and approximately 18,000 court employees.
The California Supreme Court, the court of last resort, consists of a Chief Justice and six Associate Justices. Justices are appointed by the Governor and confirmed by the Commission on Judicial Appointments (composed of the Chief Justice, the Attorney General, and the senior presiding justice of the Courts of Appeal). Justices serve 12-year terms and face retention elections in which voters decide whether to retain them for additional terms. The Supreme Court has mandatory jurisdiction over death penalty appeals and discretionary jurisdiction over other cases, typically hearing approximately 80 to 100 cases per year on issues of statewide legal significance.
The Courts of Appeal, organized into six appellate districts with divisions totaling 105 justices, hear appeals from the superior courts. Justices are appointed by the Governor and confirmed in the same manner as Supreme Court justices, serving 12-year terms subject to retention elections. The appellate courts handle approximately 20,000 filings annually.
The Superior Courts, one in each of the state's 58 counties, are the trial courts of general jurisdiction. Superior court judges are elected to six-year terms in nonpartisan elections, though vacancies are filled by gubernatorial appointment. The superior courts handle all civil and criminal cases, family law, juvenile matters, probate, and traffic cases. The Judicial Council of California, chaired by the Chief Justice, is the administrative body of the court system, establishing rules, policies, and procedures for the operation of the courts statewide.
Direct Democracy
California's system of direct democracy is among the most robust in the world and profoundly shapes the state's governance. Three principal mechanisms allow voters to participate directly in lawmaking:
The Initiative allows voters to propose and enact statutes or constitutional amendments by collecting signatures equal to 5 percent (for statutes) or 8 percent (for constitutional amendments) of the votes cast in the most recent gubernatorial election. Initiatives that qualify are placed on the next statewide ballot and require a simple majority for approval. Notable initiatives have established term limits for legislators (Proposition 140, 1990), mandated minimum education funding (Proposition 98, 1988), legalized recreational cannabis (Proposition 64, 2016), and restructured the state's criminal sentencing laws (Proposition 47, 2014).
The Referendum allows voters to reject a law passed by the Legislature by collecting signatures from 5 percent of voters in the most recent gubernatorial election within 90 days of the law's enactment. The law is then suspended pending a vote of the electorate.
The Recall allows voters to remove an elected official before the end of their term. The recall process requires signatures from a specified percentage of voters (12 percent of the votes cast in the last election for that office for statewide officials, 20 percent for state legislators). California's recall provision gained national attention in 2003 when Governor Gray Davis was recalled and replaced by Arnold Schwarzenegger, and again in 2021 when a recall attempt against Governor Gavin Newsom reached the ballot but was defeated by voters.
County Government
California's 58 counties serve as the administrative subdivisions of the state government, providing essential services in both incorporated and unincorporated areas. Counties are responsible for law enforcement (through elected sheriffs), property tax assessment and collection, vital records (birth and death certificates), elections administration, road maintenance in unincorporated areas, public health, social services, and the operation of superior courts.
Most California counties are governed by a five-member Board of Supervisors elected from single-member districts. Supervisors serve four-year terms and collectively set county policy, adopt the budget, and oversee county operations. In addition to supervisors, counties elect several constitutional officers including the sheriff, district attorney, assessor, treasurer-tax collector, and county clerk. Fourteen California counties have adopted home rule charters, granting them broader authority to organize their government structures and exercise powers not specifically denied by the state Constitution or Legislature.
San Francisco is unique in California as a consolidated city-county, operating as both a city and a county with a single government under a charter adopted in 1856 and most recently revised in 1996. The Mayor of San Francisco serves as both the city's chief executive and the effective county executive, while the Board of Supervisors serves as both the city council and the county board.
City Government
California has more than 480 incorporated cities, ranging from Los Angeles (3.9 million residents) to Vernon (approximately 200 permanent residents). Cities in California operate under one of two frameworks: general law cities, which exercise only those powers specifically granted by state law, and charter cities, which have adopted home rule charters granting broader authority over "municipal affairs." Approximately 120 of California's cities are charter cities, including all of the largest cities in the state.
Most California cities operate under either a council-manager form of government (in which an appointed city manager serves as chief executive) or a mayor-council form (in which an elected mayor serves as chief executive). Los Angeles, San Francisco, San Diego, Oakland, and Sacramento are among the cities that use a mayor-council form with strong mayoral authority. The council-manager form is more common among mid-sized and smaller cities.
California cities exercise broad authority over land use and zoning through their general plans, which are comprehensive policy documents guiding development decisions. City building departments enforce the California Building Standards Code (Title 24) within city limits and issue building permits for construction, renovation, and demolition projects. The California Contractor Authority and the California Commercial Contractor Authority provide reference information on the regulatory framework governing construction activity within city jurisdictions.
Special Districts and Agencies
California has approximately 5,000 special districts -- independent governmental entities that provide specific services within defined boundaries. Special districts range from small community services districts providing water and sewer service to rural areas to large agencies with multi-billion-dollar budgets, such as the Metropolitan Water District of Southern California, the Los Angeles County Metropolitan Transportation Authority (Metro), and the Bay Area Rapid Transit District (BART). Other common types of special districts include school districts, fire protection districts, irrigation districts, mosquito abatement districts, and park and recreation districts.
The California Constitution also establishes several independent constitutional entities, including the University of California system (governed by the Board of Regents), the California State University system (governed by the Board of Trustees), and the California Community Colleges system, which together enroll more than 3.5 million students and constitute the largest system of public higher education in the world.
