What document outlines the regulations regarding the Mechanical Contractor Act?

The correct answer is the Mechanical Law Act, as this document specifically addresses regulations and standards related to mechanical contracting within the state. This Act reinforces the licensing requirements for mechanical contractors and outlines the scope of work that falls under mechanical trades, including plumbing, HVAC (heating, ventilation, and air conditioning), and other related mechanical services.

The Skilled Trades Regulation Act focuses more broadly on various skilled trades in Michigan but does not specifically delineate the requirements and regulations unique to mechanical contracting. While it is related, it encompasses multiple trades rather than concentrating solely on mechanical concerns.

The Stille-Derossett-Hale Single State Construction Code Act is primarily concerned with construction codes across various disciplines, including safety standards and enforcement regulations, but does not specifically cater to the mechanical contracting industry. Lastly, the Construction Code Act deals with the overall regulatory framework for construction practices and safety but lacks the specific focus necessary to directly address the mechanical contracting sector. Thus, the Mechanical Law Act is the definitive source for regulations pertaining to mechanical contractors.
