In 1971, the Twenty-sixth Amendment set the legal voting age at 18 for both US federal and state elections.
http://www.ss.ca.gov/elections/gov-qual.pdf Given that a minimum age is not specified, one can assume that the minimum voting age (see B) of 18 is an unlisted qualification. State Legislation on Voting Age Existing law provides that any person who will be at least 18 years of age at the time of the next election is eligible to register and vote at that election.
