(b) The substance of the complaint shall be provided to the licensee no earlier than at the time of the inspection. Unless the complainant specifically requests otherwise, neither the substance of the complaint provided the licensee nor any copy of the complaint or any record published, released, or otherwise made available to the licensee shall disclose the name of any person mentioned in the complaint except the name of any duly authorized officer, employee, or agent of the department conducting the investigation or inspection pursuant to this chapter.

(c) Upon receipt of a complaint, other than a complaint alleging denial of a statutory right of access to a residential care facility, the department shall make a preliminary review and, unless the department determines that the complaint is willfully intended to harass a licensee or is without any reasonable basis, it shall make an onsite inspection within 10 days after receiving the complaint except where the visit would adversely affect the licensing investigation or the investigation of other agencies, including, but not limited to, law enforcement agencies. In either event, the complainant shall be promptly informed of the department’s proposed course of action.

(d) Upon receipt of a complaint alleging denial of a statutory right of access to a residential facility, the department shall review the complaint. The complainant shall be notified promptly of the department’s proposed course of action.
