Cal. Ins. Code § 1758.81
(a) An applicant for a car rental agent license under this article shall file the following documents with the commissioner:
(4) Not less than 60 days before a permanent license will expire, the commissioner may use an electronic delivery method, including email or other similar electronic method of delivery, to deliver, or may mail, to the latest email or mailing address appearing on the licensee’s records, an application to the licensee to renew the license for the appropriate succeeding license period. It is the licensee’s responsibility to renew whether or not a renewal application is received. The commissioner may accept a late renewal without a penalty, provided the licensee’s failure to comply is due to clerical error or inadvertence on the part of the department.
