SUPPLEMENTARY INFORMATION:
On May 31, 2022, DOE published in the
Federal Register
a final rule to establish energy conservation standards for manufactured housing pursuant to the Energy Independence and Security Act of 2007. 87 FR 32728. On July 11, 2026, the 21st Century ROAD to Housing Act (Pub. L. 119-101) (“ROAD Act”) was enacted. Section 301(d)(2)(B) of the ROAD Act specifies that “[n]o energy efficiency standards for manufactured homes developed by any Federal agency shall have legal effect unless and until adopted by the Department of Housing and Urban Development pursuant to the consensus standards and regulatory development process described in . . . 42 U.S.C. 5403(a)(2)).” Section 301(d)(2)(C) of the ROAD Act requires the Department of Housing and Urban Development (“HUD”) to “adopt minimum energy efficiency standards for manufactured homes” within one year of enactment, and to update those standards every three years.
As of the date of this notification, no minimum energy efficiency standards meeting the requirements under section 301(d) of the ROAD Act have been adopted by HUD. Therefore, it is DOE's position that the final rule published in the
Federal Register
on May 31, 2022, establishing energy conservation standards for manufactured housing has no legal effect pursuant to section 301(d)(2)(B) of the ROAD Act.
The Department intends to initiate a rulemaking to conform DOE's regulations for manufactured housing to account for the statutory changes adopted by the ROAD Act, and further notes that DOE will not enforce its energy conservation standards for manufactured housing as they have no legal effect under the ROAD Act.
