Construction, Codes and Standards

Virtually all residential construction must adhere to comprehensive building codes and standards governed by local and state laws. Because of the cost and complexity of developing and maintaining such codes, state and local governments typically adopt nationally recognized model codes, often amending them to reflect local construction practices, climate and geography. Most U.S. communities adopt the International Code Council’s I-Codes for this purpose. The I-Codes address all aspects of single- and two-family as well as multifamily construction, including structural elements and the electrical, plumbing, heating, ventilation and air conditioning systems, and energy conservation requirements.

Why It Matters

Building codes can have a profound impact on the comfort and safety of residents as well as the cost of construction and the cost of operating the home. NAHB can help its members work toward cost-effective and safe codes. Visit NAHB to learn more.
