# Government of San Francisco

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
The government of the City and County of San Francisco utilizes the "strong mayor" form of mayoral/council government, composed of the Mayor, Board of Supervisors, several elected officers, and numerous other entities. It is the only consolidated city-county in California, and one of only thirteen charter counties of California. The fiscal year 2019–20 city and county budget was approximately $12.3 billion.

## Organization

San Francisco utilizes the "strong mayor" form of mayoral/council government, composed of the mayor, Board of Supervisors, several elected officers, and numerous other entities. San Francisco voters use ranked-choice voting to elect the mayor, supervisors, and other elective officers.

### Mayor

The Mayor of San Francisco is the head of the executive branch of the city and county government. The mayor has the responsibility to enforce all city laws, administer and coordinate city departments and intergovernmental activities, set forth policies and agendas to the Board of Supervisors, and prepare and submit the city budget at the end of each fiscal year. The mayor has the powers to either approve or veto bills passed by the San Francisco Board of Supervisors, participate in meetings of the Board of Supervisors and its committees, appoint a replacement to fill vacancies in all city elected offices until elections, appoint a member of the Board as acting mayor in his/her absence, and to direct personnel in the case of emergency. The mayor serves a four-year term and is limited to two successive terms. If the mayor dies or resigns, the President of the Board of Supervisors assumes the office as acting mayor. This has occurred twice since the 1970s: Dianne Feinstein became acting mayor after the assassination of George Moscone in 1978, and London Breed became acting mayor following the death of Ed Lee from a heart attack in 2017.
The current mayor as of 2025 is Daniel Lurie.

### Board of supervisors

The legislative body is composed of the 11-member Board of Supervisors which acts as both a board of supervisors and a city council, with "[a]ll rights and powers of a City and County which are not vested in another officer or entity" by the charter. The Board of Supervisors is headed by a president and is responsible for passing laws and budgets.

## Municipal law

Pursuant to its charter, San Francisco causes to be published several codified version of its ordinances and regulations, the San Francisco Municipal Codes. Every act prohibited or declared unlawful, and every failure to perform an act required, by the ordinances are misdemeanor crimes, unless otherwise specified as infractions.

### San Francisco plague of 1900–1904

In the 1890s San Francisco received heavy ship traffic from Asian cities that were currently dealing with the bubonic plague. In 1889, a ship from Hong Kong was found to have two cases of bubonic plague on board. The bodies washed up on the bay later, but no immediate outbreak occurred at this initial finding. In 1900 a city health officer autopsied a Chinese man and found evidence of the plague. With anti-Chinese feelings already running rampant throughout the city, the Department of Public Health quickly moved to quarantine Chinatown. Initially the quarantine was protested, not to protect the Chinese, but because of fear and doubt that the plague was indeed in the city. The mayor at the time, James D. Phelan, created the Board of Health, which included multiple doctors on the board. He demanded the Board of Health have 100 physicians search a 12-block area in Chinatown for more cases of the plague. After victims were found, the Board of Health publicly announced the plague, and the Chinatown quarantine was again set into place.
Health officials shut down Chinese-owned businesses, and any Chinese or Japanese people attempting to leave the city had to first go through an inoculation with an experimental prophylactic developed by Waldemar Haffkine. This led to a court case between Chinatown resident Wong Wai and the Department of Public Health. Wai won the court case and the Department of Public Health was ordered to stop the inoculations, but city officials got support from the Board of Supervisors to continue. Health authorities also attempted to set up a detention camp for those of Asian descent in Mission Rock, but the idea was protested and canceled, partially due to fear about openly admitting the plague in San Francisco.
Fear of the plague and prejudice against Chinese was so high that many city officials debated burning down Chinatown. The idea popular, especially since this had been done in Honolulu. To prevent their homes from being burnt down and break the quarantine, the Chinese rallied the Chinese Six Companies, multiple attorneys, and China's diplomat. Together, they were ultimately able to get the quarantine lifted again. This was again in part due to the government's fear of publicly confirming plague.
Health authorities from 21 states eventually passed a resolution about California's neglect of duties to address the plague in San Francisco and threatened to close all trade with California. San Francisco businessmen reacted by assembling the Chamber of Commerce, Board of Trade, Merchants’ Association, Marine Hospital Service, new mayor George C. Pardee and various and civil rights groups to clear San Francisco of the plague.

## Education

There are several school districts that are co-extensive with San Francisco. The San Francisco Unified School District is governed by the elected seven-member San Francisco Board of Education. The community college district of the City College of San Francisco is governed by an elected seven-member Board of Trustees.

## Regional governments

In addition, several regional governmental units in San Francisco operate independently of the municipal government. Five regional agencies—the Association of Bay Area Governments, Metropolitan Transportation Commission, Bay Area Air Quality Management District, San Francisco Bay Regional Water Quality Control Board, and Bay Conservation and Development Commission—have jurisdiction over San Francisco and the other Bay Area counties, and San Francisco appoints representatives to their governing boards.
Several transit agencies provide transit service within San Francisco and adjacent counties, including the Bay Area Rapid Transit (BART), of which residents elect Board of Directors for districts 7, 8, and 9, Golden Gate Transit, Caltrain, the San Francisco Bay Area Water Emergency Transportation Authority, and the Metropolitan Transportation Commission.
