California Code, Business and Professions Code - BPC § 7506.10

(a) Every initial registration shall expire one year following the date of issuance, unless renewed as provided in this section.  A renewal registration shall expire two years following the date of renewal, unless renewed as provided in this section.

(b) At least 60 days prior to the expiration, the bureau shall mail a renewal form to the registrant at the licensee's place of business.  A registrant who desires to renew their registration shall forward to the bureau for each registration the properly completed renewal form obtained from the bureau, with the renewal fee prescribed by this chapter, for renewal of their registration.  Until the registration renewal certificate is issued, a registrant may continue to work with a temporary registration renewal certificate on a secure form prescribed by the chief and issued by the qualified certificate holder that has been embossed by the bureau with the state seal for a period not to exceed 120 days from the date of expiration of the registration.

(c) A licensee shall provide to their registrants information regarding procedures for renewal of registration.

(d) A registration that is not renewed within 60 days after its expiration may not be renewed.  If the registration is renewed within 60 days after its expiration, the registrant, as a condition precedent to renewal, shall pay the renewal fee and also pay the delinquency fee prescribed in this chapter.  Registrants working with expired registrations shall pay all accrued fees and penalties prior to renewal or reregistration.

(e) Upon renewal, evidence of renewal, as the director may prescribe, shall be issued to the registrant.  If evidence of renewal has not been delivered to the registrant prior to the date of expiration, the registrant may present evidence of renewal to substantiate continued registration for a period not to exceed 60 days after the date of expiration or a temporary registration renewal certificate, as described in subdivision (b).

(f) A registration shall not be renewed until any and all fines assessed pursuant to this chapter and not resolved in accordance with this chapter have been paid.
