The Government of San Diego County is defined and authorized under the California Constitution, California law, and the Charter of the County of San Diego.[1] Much of the Government of California is in practice the responsibility of county governments such as the Government of San Diego County. The County government provides countywide services such as elections and voter registration, law enforcement, jails, vital records, property records, tax collection, public health, and social services. In addition the County serves as the local government for all unincorporated areas.

The county government is composed of the elected five-member Board of Supervisors, several other elected offices and officers including the Sheriff, the District Attorney, Assessor/Recorder/County Clerk, and Treasurer/Tax Collector, and numerous county departments and entities under the supervision of the Chief Administrative Officer such as the Probation Department.

Some chartered municipalities such as the city of San Diego and the city of Chula Vista provide their own law enforcement, public safety, libraries, parks and recreation, zoning, and similar services. Other incorporated cities have some or all of these services provided by the County under a contract arrangement. In addition, several entities of the government of California have jurisdiction conterminous with San Diego County, such as the San Diego Superior Court.

The county motto is "The noblest motive is the public good." County government offices are housed in the historic County Administration Center building, constructed from 1935 to 1938 with funding from the Works Progress Administration.[2]

San Diego County is represented by the Third District in the State Board of Equalization.

The San Diego Superior Court, which covers the entire county, is not a County department but a division of the State's trial court system. Historically, the courthouses were county-owned buildings that were maintained at county expense, which created significant friction since the trial court judges, as officials of the state government, had to lobby the county Board of Supervisors for facility renovations and upgrades. In turn, the state judiciary successfully persuaded the state Legislature to authorize the transfer of all courthouses to the state government in 2008 and 2009 (so that judges would have direct control over their own courthouses). Courthouse security is still provided by the county government under a contract with the state.

The Richard J. Donovan Correctional Facility of the California Department of Corrections and Rehabilitation is in an unincorporated area in the county.[9]

San Diego[edit]

The government of San Diego consists principally of a mayor and a nine-member city council. In 2006, the city's form of government changed from a "city manager system" to a "strong mayor system". The change was brought about by a citywide vote in 2004. The mayor is in effect the chief executive officer of the city, while the council is the legislative body.[10]

The members of the city council are each elected from single member districts within the city. The mayor and city attorney are elected directly by the voters of the entire city. The mayor, city attorney, and council members are elected to four-year terms, with a two-term limit.[11] Elections are held on a non-partisan basis per California state law; nevertheless, most officeholders do identify themselves as either Democrats or Republicans.

In 2015, registered Democrats outnumbered Republicans by about 39% to 26% the city,[12] and Democrats currently hold an 8-1 majority in the City Council.
