The City of Sunnyvale is a charter city. A charter is a foundational document, similar to a constitution, which authorizes the creation of the city and outlines its powers, functions, and organization. The original Charter of the City of Sunnyvale was established by vote of the people of the City of Sunnyvale as the organic law of the City under the authority of the Constitution of the State of California and became effective May 18, 1949. Amendments to the Charter must be ratified by a majority of the voters of the City at a municipal election held for that purpose.
