Bill > HB939

This bill modifies Missouri state law regarding the adoption of building codes by adding new restrictions on local government regulations. Specifically, the bill defines key terms like "code" and "community" and clarifies that local governments (counties and municipalities) can adopt technical building codes by reference. The significant new provision prohibits local governments from mandating green building or energy efficiency standards that could potentially increase construction costs, effectively blocking requirements related to sustainable building practices, high-performance energy features, and energy efficiency standards beyond those defined in the 2009 International Residential Code and 2009 International Energy Conservation Code. Any local ordinance that attempts to impose such standards would be considered null and void. The bill appears designed to prevent localities from implementing more stringent environmental or energy-efficient building requirements that might increase construction expenses, with the goal of maintaining affordability in residential and commercial building development.
