Cal. Health & Saf. Code § 33744
Whenever a complaint is received concerning a violation of the restrictions imposed pursuant to Section 33742, the agency shall investigate promptly and make a report to the complaining party on whether the violation existed and whether it persists, and if it persists, what action the agency will take to remedy the violation. When the agency determines that a violation exists, whether determined upon an investigation of a complaint or on its own motion, the agency shall take all appropriate action, including necessary legal action, to promptly eliminate the violation.
Notwithstanding other provisions of this section, any person aggrieved by a violation of the restrictions imposed pursuant to Section 33742 may seek a judicial remedy without regard to whether a complaint has been made to the agency or whether the agency is then taking any action to remedy the violation.
