Key Takeaways

On April 24, the U.S. Department of Housing and Urban Development (HUD) and the U.S. Department of Agriculture (USDA) announced the adoption of new energy-efficiency standards for the construction of new single and multifamily homes. The standards will apply to new construction under several HUD and USDA programs and will go into effect on May 28, 2024.

What are the new standards?

The new standards fulfill a requirement from the Energy Independence and Security Act of 2007 (P.L. 110-40) that directs HUD and USDA to adopt the most recently published energy-efficient standards that are supported by the 

  • International Energy Conservation Code (IECC)
  • American National Standards Institute (ANSI)
  • American Society for Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)
  • Illuminating Engineering Society (IES)

HUD and USDA have not updated their energy efficiency standards since 2015 and this action will bring them back into compliance with the statute. 
Highlights of this action include:

  • The new standards apply to new construction financed through the HOME Investment Partnerships Program, Project Based Vouchers, Choice Neighborhood Grants, USDA Direct and Guaranteed Home Loan programs, the Housing Trust Fund and more.
  • Community Development Block Grant (CDBG)-financed housing is excluded from these standards.
  • In persistent rural poverty areas, compliance with the new standards will be required 24 months after the May 28 start date.

How will counties and our residents be impacted?

  • As of December 2023, six states (California, Washington, Connecticut, New Jersey, Vermont, and Illinois) have already adopted the 2021 IECC, and five states (Florida, Louisiana, Montana, Maryland, and Oregon) adopted the 2021 IECC with weakening amendments. 
  • Housing will generally have more insulation in the walls and roofs, better air sealing and windows, more energy-efficient heating and cooling systems, and reduced pollution.
  • HUD and USDA estimate that code compliance costs from this rule on average will add approximately $37 to monthly mortgage payments, but save homeowners $80 a month on monthly energy bills, resulting in a yearly savings of $524.
