California Code, Labor Code - LAB § 1700.10

The license when first issued shall run to the next birthday of the applicant, and each license shall then be renewed within the 30 days preceding the licensee's birthday and shall run from birthday to birthday. In case the applicant is a partnership, such license shall be renewed within the 30 days preceding the birthday of the oldest partner. If the applicant is a corporation, such license shall be renewed within the 30 days preceding the anniversary of the date the corporation was lawfully formed. Renewal shall require the filing of an application for renewal, a renewal bond, and the payment of the annual license fee, but the Labor Commissioner may demand that a new application or new bond be submitted.

If the applicant or licensee desires, in addition, a branch office license, he shall file an application in accordance with the provisions of this section as heretofore set forth.
