Construction: code; definitions under Stille-DeRossett-Hale single state construction code act; modify. Amends sec. 2a of 1972 PA 230 (MCL 125.1502a). TIE BAR WITH: HB 6303'26

Michigan House Bill 6304 amends the Stille-DeRossett-Hale single state construction code act to update and clarify definitions used in the state's building regulations. The bill introduces new terms such as "air tightness testing," "building envelope," and "cost-effective" regarding energy efficiency standards, while refining existing definitions for concepts like "agricultural purposes," "mobile home," and "structure." These changes directly affect local governments, building officials, and property owners by establishing a more precise legal framework for enforcing construction codes. The bill is tied to HB 6303 and will not take effect unless that companion legislation is also enacted into law.
