Top 10 States for NGBS Green Certification Activity in 2024
With more than 600,000 homes certified to the National Green Building Standard (NGBS) since its launch in 2009, builders across the United States are continually adding to the pipeline of NGBS projects.
The NGBS provides home builders with a national standard to define and measure sustainable multifamily and single-family homes, developments and remodeling projects. Third-party green certification also offers consumers a level of confidence that they are purchasing an independently verified green property.
Here’s a snapshot of the top NGBS Green certification activity by state in 2024 for both single-family and multifamily projects:
Four states rank in the top 10 for both single-family and multifamily projects in 2024: Virginia, North Carolina, Maryland and Florida. Texas once again tops multifamily certification, and Florida took the top spot for most single-family certification.
NGBS certification activity generally aligns with areas that are seeing the most new home building. Arizona is a new addition to the multifamily certification Top 10 last year, and Alabama is a new addition to the single-family list.
The NGBS program is administered through Home Innovation Research Labs™. Builders can learn more about the value of NGBS Green certification at nahb.org.
