The National Association of Home Builders (NAHB) is one of the largest trade associations in the United States, based upon 2011 annual budgets. Headquartered in Washington, D.C., NAHB’s mission is “to enhance the climate for housing and the building industry. Chief among NAHB’s goals is providing and expanding opportunities for all consumers to have safe, decent and affordable housing.” Founded in 1942, NAHB is a federation of more than 800 state and local associations. About one-third of NAHB’s more than 140,000 members are home builders or remodelers. The remaining members are associates working in closely related fields within the housing industry such as mortgage finance and building products and services. NAHB’s various groups analyze policy issues, take the industry’s story to the public through the media and other outlets, monitor and work toward improving the housing finance system, analyze and forecast economic and consumer trends, and educate, train and disseminate information to members. NAHB represents the industry’s interests on Capitol Hill. NAHB also works with federal agencies on regulations affecting the housing industry in areas such as mortgage finance, codes, energy and the environment. It maintains the NAHB Research Center. NAHB organizes one of the largest conventions in North America, the International Builders’ Show. It is the largest show of its kind for the residential and light commercial construction industry. Each year, NAHB members build approximately 80% of new homes constructed in the United States. In 2005 NAHB was among the 53 entities that contributed the maximum $250,000 to the second inauguration of President George W. Bush.
