Which document serves as the official model code for building construction in the U.S.?

The International Building Code (IBC) is recognized as the official model code for building construction in the United States. It provides comprehensive regulations for the design and construction of buildings, addressing various aspects such as structural integrity, fire safety, accessibility, and energy efficiency. The IBC is developed by the International Code Council (ICC) and is widely adopted by state and local jurisdictions across the country, serving as a benchmark for ensuring safety and compliance in the built environment.

While the International Residential Code focuses specifically on residential buildings and the International Energy Conservation Code addresses energy efficiency, the IBC encompasses all types of buildings, including commercial and industrial structures. Similarly, the National Fire Protection Code primarily deals with fire prevention and safety measures but does not serve as a comprehensive building construction code. This broad applicability and comprehensive nature distinguish the IBC as the key document governing building regulations in the U.S.
