Manufactured Housing Affordability and Energy Efficiency Act of 2023

This bill clarifies that the Department of Housing and Urban Development (HUD) has final authority over energy efficiency standards for manufactured housing. It requires any energy standards developed under federal law (like those from the Energy Independence and Security Act) to be formally adopted into HUD's manufactured housing construction standards before becoming enforceable. The bill directly affects manufactured housing manufacturers and HUD, as it ensures HUD - not other agencies - controls which energy standards apply. Key provisions eliminate references to the International Energy Conservation Code (IECC) and establish HUD as the sole authority for adopting these standards into its code. This streamlines the process but does not create new energy requirements.
