(1) An employee of a private or public employment agency or labor union, a building code compliance inspector, an employee of the department, a person who is professionally responsible for a job site, or a plumber licensed under Title 37, chapter 69, has the right to ask a person working at a job site doing work that requires a plumber's license to provide proof of licensure.

(2) An employee of the department may issue a citation to and collect a fine, as provided in 37-69-310, from a person at a job site where the person is performing plumbing work if the person fails to display a plumber's license or proof of licensure at the request of the department inspector.
