Illinois Statutes Chapter 225. Professions,Occupations and Business Operations § 320/18. Local regulation; Department standards

(1) It is hereby declared to be the policy of this State that each city, town, village, township or county with a water supply system or sewage disposal system or both should so soon after the enactment of this Act as practicable, with the advice of the State Department of Public Health, provide by ordinance, bylaws or rules and regulations for the materials, construction, alteration, and inspection of all plumbing placed in or in connection with any building in any such city, town, village, township, or county and to provide for and appoint a competent Plumbing Inspector or more as required. The Department may by rule establish voluntary standards for the content and conduct of local plumbing regulation and inspection programs and may evaluate and certify local programs that are in compliance with the voluntary standards. The Department may by rule establish voluntary education, training, and experience standards for Plumbing Inspectors and may certify Plumbing Inspectors who are in compliance with the voluntary standards. Nothing contained in this Act shall prohibit any city, town, village, township or county from providing for a Plumbing Inspector or from requiring permits for the installation and repair of plumbing and collecting a fee therefor, but a city, town, village, township, or county that requires a permit for installation and repair of plumbing may not issue that permit without verification that the applicant has a valid plumbing license or that the applicant is the owner occupant of a single family residence that is the subject of the permit. For the purpose of this Section, the term “occupant” has the same meaning as in subsection (2) of Section 3 of this Act. No person shall be appointed as a Plumbing Inspector who is not a licensed plumber under this Act, including persons employed as Plumbing Inspectors in home rule units.

(2) The Department of Public Health shall conduct inquiry in any city, town, village, township, or county or at any other place in the State when reasonably necessary in the judgment of the Director of the Department of Public Health to safeguard the health of any person or persons in this State, on account of piping or appurtenant appliances within any building, or outside, when such piping and appliances are for the use of plumbing as defined in this Act and for the use of carrying sewage or waste within or from any building.

The Department of Public Health may conduct such inquiries in any city, town, village, township or county in this State by directing the Plumbing Inspector thereof to aid in or conduct such inquiry or investigation in behalf of the Department of Public Health or the Department of Public Health may designate some other person or persons to conduct such investigation.
