The National Association of Home Builders (NAHB) helps its members build communities. Each year, NAHB’s members construct about 80% of the new homes built in the United States, both single-family and multifamily. A federation of more than 800 state and local associations, NAHB represents more than 140,000 members. About one-third are home builders and remodelers. The rest work in closely related specialties such as sales and marketing, housing finance, and manufacturing and supplying building materials.
