Cal. Business and Professions Code § 1686

A person whose license, certificate, or permit has been revoked or suspended, who has been placed on probation, or whose license, certificate, or permit was surrendered pursuant to a stipulated settlement as a condition to avoid a disciplinary administrative hearing, may petition the board for reinstatement or modification of penalty, including modification or termination of probation, after a period of not less than the following minimum periods have elapsed from the effective date of the decision ordering disciplinary action: (a) At least three years for reinstatement of a license revoked for unprofessional conduct or surrendered pursuant to a stipulated settlement as a condition to avoid an administrative disciplinary hearing. (b) At least two years for early termination, or modification of a condition, of a probation of three years or more. (c) At least one year for modification of a condition, or reinstatement of a license revoked for mental or physical illness, or termination, or modification of a condition, of a probation of less than three years. The petition shall state any fact required by the board. The petition may be heard by the board, or the board may assign the petition to an administrative law judge designated in Section 11371 of the Government Code. In considering reinstatement or modification of penalty, the board or the administrative law judge hearing the petition may consider (1) all activities of the petitioner since the disciplinary action was taken, (2) the offense for which the petitioner was disciplined, (3) the petitioner’s activities during the time the license, certificate, or permit was in good standing, and (4) the petitioner’s rehabilitative efforts, general reputation for truth, and professional ability. The hearing may be continued from time to time as the board or the administrative law judge as designated in Section 11371 of the Government Code finds necessary. The board or the administrative law judge may impose necessary terms and conditions on the licentiate in reinstating a license, certificate, or permit or modifying a penalty. A petition under this section shall not be considered while the petitioner is under sentence for any criminal offense, including any period during which the petitioner is on court-imposed probation or parole. A petition shall not be considered while there is an accusation or petition to revoke probation pending against the person. The board may deny without a hearing or argument any petition filed pursuant to this section within a period of two years from the effective date of the prior decision following a hearing under this section. This section shall not be deemed to alter Sections 822 and 823.
