Cal. Bus. & Prof. Code § 7077
Every original license, except an additional classification issued pursuant to Section 7059, shall be a probationary license until such time as the license is renewed. If information is brought to the attention of the registrar, during such probationary period, regarding any act or omission of the licensee constituting grounds for denial, revocation, or suspension of an application or license, such that, in the registrar's discretion, it would be proper to revoke the probationary license, the registrar shall forthwith notify the applicant to show cause within not more than 30 days, why the probationary license should not be revoked. The proceedings shall be conducted in accordance with the provisions of Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code, and the registrar shall have all the powers granted therein. A probationary license shall not be renewed during the pendency of any proceedings brought pursuant to this section.
