The department is authorized to enter at all times in or on the property of any facility or service, whether public or private, licensed by the department or unlicensed, for the purpose of inspecting and investigating conditions relating to a violation of this article or regulations of the department. The department’s authorized agents may examine and copy any records or memoranda pertaining to the operation of a licensed or unlicensed facility or service to determine compliance with this article. However, if such entry or inspection is denied or not consented to and no emergency exists, the department is empowered to obtain a warrant to enter and inspect the property and its records from the magistrate in the jurisdiction in which the property is located. The magistrate may issue these warrants upon a showing of probable cause for the need for entry and inspection. The department shall furnish a written copy of the results of the inspection or investigation to the owner or operator of the property.
