Where New-Construction Home Sales Grew the Most in 2025

New-home sales grew most in Southern and Western U.S. counties in 2025, with Tennessee's Wilson County and Arizona's Maricopa County leading at 44% growth. The South and West benefit from more permissive zoning, enabling higher volumes of affordable homes. The Midwest saw modest growth, led by Will County, IL, where smaller homes increased. The Northeast lagged due to stricter regulations and higher costs. Regionally, the South declined 3.7%, the Midwest rose 0.5%, and the West increased 2.4%.
