Except as otherwise provided in this article, an expired license may be renewed at any time within three years after its expiration on filing of an application for renewal on a form prescribed by the board, and payment of all accrued and unpaid renewal fees. If the license is renewed after its expiration the licensee, as a condition precedent to renewal, shall also pay the delinquency fee prescribed by this article. Renewal under this section shall be effective on the date on which the application is filed, on the date on which the renewal fee is paid, or on the date on which the delinquency fee, if any, is paid, whichever last occurs. If so renewed, the license shall continue in effect through the date provided in Section 2538.53 which next occurs after the effective date of the
renewal, when it shall expire if it is not again renewed.
