DOE Energy Conservation Standards for Manufactured Housing

Current understanding

The Department of Energy issued energy conservation standards for manufactured homes in 2022 under its Energy Conservation Program authority. In a final rule, DOE announced that these standards no longer have legal effect because Congress overrode them in the ROAD to Housing Act of 2025. For buyers of new manufactured homes, this removes a federal floor on building-envelope and equipment efficiency; for builders, it eliminates the compliance obligation DOE had phased in; for renters in manufactured-home communities, downstream effects on utility costs are undetermined.
