Recent and Ongoing Activities

DOE has published a Federal Register notice publishing a final rule to amend the compliance date for its manufactured housing energy conservation standards. Currently, manufacturers must comply with these standards on and after May 31, 2023. This final rule delays compliance until July 1, 2025, for Tier 2 homes, and until 60 days after issuance of enforcement procedures for Tier 1 homes. DOE is delaying the compliance date to allow DOE more time to establish enforcement procedures that provide clarity for manufacturers and other stakeholders regarding DOE’s expectations of manufacturers and DOE’s plans for enforcing the standards.

  • This final rule is effective May 30, 2023.

DOE has published a Federal Register final rule to establish energy conservation standards for manufactured housing pursuant to the Energy Independence and Security Act of 2007. This document presents standards based on the 2021 version of the International Energy Conservation Code (IECC) and comments received during interagency consultation with the U.S. Department of Housing and Urban Development, as well as from stakeholders. The adopted standards would provide a set of “tiered” standards based on size that would apply the 2021 IECC-based standards to manufactured homes, except that single-section manufactured homes would be subject to less stringent building thermal envelope requirements compared to multi-section manufactured homes.

  • The effective date of this rule is August 1, 2022.
  • Compliance with the adopted standards established for manufactured housing in this final rule is required on and after May 31, 2023. 
  • The incorporation by reference of certain publications listed in this rule is approved by the Director of the Federal Register August 1, 2022.
