California Code, Business and Professions Code - BPC § 19290

(a) Permits issued under this chapter expire two years from the date of issuance. To renew a permit, a permittee shall, on or before the date on which it would otherwise expire, apply for renewal on a form prescribed by the chief, and continue to pay the fees prescribed in Sections 19288 and 19288.1. Notwithstanding Section 163.5, if a permittee fails to renew the permit before its expiration, a delinquency fee of 20 percent of the most recent fee paid to the bureau pursuant to Sections 19288 and 19288.1 shall be added to the amount due to the bureau at the next fee interval. If the renewal fee and delinquency fee are not paid within 90 days after expiration of a permit, the permittee shall be assessed an additional fee of 30 percent of the most recent fee paid to the bureau pursuant to Sections 19288 and 19288.1.

(b) Except as otherwise provided in this chapter, a permittee may renew an expired permit within two years after expiration of the permit by filing an application for renewal on a form prescribed by the bureau, and paying all accrued fees.

(c) A permit that is not renewed within two years of its expiration shall not be renewed, restored, reinstated, or reissued, but the holder of the expired permit may apply for and obtain a new permit as provided in this chapter, upon payment of all fees that accrued since the date the permit was last renewed.

(d) The bureau may impose conditions on any permit issued pursuant to subdivision (c).
