HUD and USDA’s Six-Month Delay on Enforcing 2021 IECC Rule A Win for Housing
This post has been updated.
In a win for NAHB and the housing industry, the Trump administration has in the implementation of the Biden administration’s mandatory energy code, an important step forward to help ease the nation’s housing affordability crisis.
Specifically, the Department of Housing and Urban Development (HUD) and Department of Agriculture (USDA) will wait an additional six months before enforcing the compliance dates for adopting the 2021 International Energy Conservation Code (IECC) and ASHRAE 90.1-2019 as the minimum energy-efficiency standards for certain single-family and multifamily housing programs.
“This six-month pause by HUD and USDA is an important step forward to help ease the nation’s housing affordability crisis,” said NAHB Chairman Buddy Hughes. “Compliance with this rule would make it much harder for home builders and multifamily developers to build housing that is available and affordable for American families.
In fact, the Home Innovation Research Labs has found that compliance with the 2021 IECC can add more than $20,000 to the price of a new home, but in practice, home builders have estimated increased costs of up to $31,000.
The updated compliance dates are as follows:
Program | Initiation Event | Compliance Date |
HOME and HTF (If HOME/HTF funding is layered with other HUD funds, the later program compliance date applies) |
Participating Jurisdiction (PJ) or HTF Grantee Funding Commitment | Nov. 28, 2024 |
Federal Housing Administration-Insured (FHA-Insured) Multifamily | Pre-application Submitted to HUD | Nov. 28, 2025 |
FHA-Insured Single Family | Building Permit Application | May 28, 2026 |
Public Housing Capital Fund | HUD approvals of development proposals for new Capital Fund or mixed financed projects | Nov. 28, 2025 |
Project Based Vouchers | To be determined in further guidance | April 1, 2026 |
Competitive Grants (Choice Neighborhoods, Section 202, Section 811) | Notice of Funding Opportunity (NOFO) Publication | Next published NOFO after six months from the date of publication of this notice |
All programs, persistent poverty rural areas | Based on program-specific event, above | May 28, 2026 |
Rental Assistance Demonstration (RAD) | N/A | Already effective by Federal Register Notice July 27, 2023 |
NAHB commends the Trump administration for recognizing the importance of bringing down the cost of housing and will continue to pursue all avenues on the congressional, regulatory and legal fronts to overturn this harmful energy code rule.

The most common sources for products used in home building and remodeling are specialty retailers, lumber yards, and wholesale distributors, according to two recent NAHB surveys. The surveys include one of single-family homebuilders in the October 2024 NAHB/Wells Fargo Housing Market Index (HMI) and one of remodelers in the Q3 2024 NAHB/Westlake Royal Remodeling Market Index (RMI). Both surveys asked respondents where they purchase building products, regardless of who ultimately purchases them (themselves or subcontractors).
