The Affordable HOMES Act of 2026 prohibits the Department of Energy Secretary from enforcing federal energy efficiency standards for manufactured housing. Instead, the bill allows the Energy Secretary only to recommend revisions to these standards to the Department of Housing and Urban Development, and any recommendations must consider the cost-effectiveness of the standards, their impact on home purchase prices, and the unique manufacturing constraints of mobile homes. The legislation specifically voids a 2022 Department of Energy rule that established energy efficiency standards for manufactured housing. This bill primarily affects manufactured home builders, buyers, and the affordability of mobile homes, as manufacturers would no longer be required to meet the federal energy efficiency requirements that had previously applied to their products.
