The bill amends the Skilled Trades Regulation Act to enhance the regulation of skilled trades in Michigan by introducing specific fees for licenses and permits, particularly increasing fees for those applying after violating section 608, which addresses fraudulent license use. It establishes penalties for licensing violations, including misdemeanors and felonies, and allows for civil fines and ineligibility for licensure for individuals who alter or fraudulently use a license. New provisions are added to define and regulate automatic fire suppression systems and clarify the scope of work exempt from licensing, such as minor repairs and certain electrical tasks, while detailing the responsibilities of enforcing agencies regarding construction violations.

Additionally, the bill updates licensing requirements for mechanical contractors and technicians, specifying that credited experience for applicants cannot exceed one year or 2,000 hours, and that licenses are valid for three years. It mandates that mechanical contractors complete a course on updates to the state construction code for license renewal and outlines the requirements for obtaining a journey mechanical technician license. The bill also clarifies that only licensed individuals may perform regulated work and sets fees for various licenses, including a $40 fee for journey mechanical technicians. It introduces exemptions for certain individuals from licensing requirements, such as those registered under the security alarm systems act, aiming to streamline processes while ensuring safety compliance.
