Whenever EH has reasonable grounds to believe that a public health nuisance exists, an inspection may be made of such premises, dwelling, or other building in order to gather information and evidence. Information and evidence may include, but is not limited to, taking statements from residents and neighbors, taking pictures, measuring distances, and collecting water samples, soil samples, and other necessary specimens for the purpose of laboratory analysis. The EH shall enter such premises to make inspections and to obtain samples as are necessary for the investigation. Such inspection shall be made between the hours of 8:00 a.m. and 5:00 p.m., Monday through Friday, and at other times with the consent of the occupant, or in case of emergency. The provisions of this section shall apply to all premises, buildings, or dwellings, vacant or occupied. EH may make as many additional inspections of such premises as are deemed necessary.
