The Insurance Commissioner

The Insurance Commissioner is:

  • Elected by California voters to a 4-year term
  • One of only 11 states where the commissioner is elected
  • Responsible for enforcing the California Insurance Code
  • Authorized to adopt regulations, review rates, investigate violations, and discipline licensees
