The International Building Code (IBC) is developed and maintained by the International Code Council (ICC). The IBC is a set of standards and regulations for building design and construction that are widely used in the United States and other countries. It covers various aspects of building construction such as fire safety, structural design, accessibility, and energy efficiency. The IBC is updated every three years to reflect new technologies, advancements in building science, and changes in societal needs. Its purpose is to ensure the safety and welfare of building occupants by establishing minimum requirements for the design, construction, and maintenance of buildings.
