Cal. HSC § 1215

Each new license issued pursuant to this chapter shall expire 12 months from the date of its issuance, and each special permit shall expire on the expiration date of the underlying license. The state department shall transmit to the licensee a renewal fee invoice at least 45 days prior to the expiration date of the license. Failure by the clinic licensee to make timely payment of the renewal fee shall result in the expiration of the license and special permit, if any. A renewal license or special permit may be issued for a period not to exceed two years if the holder of the license or special permit has not been found to be in violation of any statutory requirements, regulations, or standards during the preceding license period. In all other cases, the renewal license or special permit shall be issued for a period not to exceed one year. Timely application for renewal, accompanied by the necessary fee, shall be deemed equivalent to renewal of a license or special permit, where the department is unable to issue a renewal license or special permit on or before the expiration date.
