Occupations: plumbers; ratio of apprentices to journey or master licensees on a jobsite; provide for plumbers and modify for electricians. Amends sec. 1117 of 2016 PA 407 (MCL 339.6117) & adds sec. 1117a.

This bill updates Michigan's skilled trades regulations to set specific supervision ratios for both electricians and plumbers on job sites. It requires that no more than two apprentice electricians work under one journeyman or master electrician, while limiting apprentice plumbers to a maximum of two per journeyman or master plumber. To enforce these rules, the law establishes escalating penalties for violations, including fines up to $10,000 and potential license suspensions for contractors who exceed the allowed apprentice-to-supervisor limits. Additionally, the bill mandates that all registered apprentices must sign up with the state board within 30 days of starting their employment.
