NAHB and ICC Release 2025 Edition of the National Green Building Standard

The National Association of Home Builders (NAHB) and the International Code Council (ICC) announced the release of the ICC 700-2025 National Green Building Standard (NGBS)—the fifth edition of the residential green building standard. Approved by the American National Standards Institute (ANSI), the 2025 NGBS continues to define the benchmark for sustainable residential construction, renovation and land development across the United States.

Developed through an independent consensus committee representing a broad range of stakeholders, the 2025 NGBS reflects leading thinking in green design, construction and building performance. It applies to single-family homes, multifamily buildings, mixed-use developments and land development projects, as well as other similarly constructed residential facilities.

What people are saying

“The 2025 NGBS represents nearly two decades of progress and innovation in sustainable residential construction and remodeling,” says Bill Owens, a builder and remodeler from Worthington, Ohio.  “This edition expands the possibilities for high-performance, resilient and low-carbon homes that meet the evolving needs of both the housing industry and homeowners.”

“We are committed to continually advancing codes and standards,” says ICC Chief Executive Officer, John Belcik. “Together, with NAHB, we are proud to introduce this updated standard for high-performance buildings, which is an achievement born from a longstanding, collaborative relationship.”
