International Code Council’s (ICC) building codes largely guide architecture, engineering, and construction industries to build safer and healthy built environment. Building codes continuously evolve in response to tragic incidents, technological advancements, and changing environmental dynamics. The scope and complexity of the building codes require practitioners, reviewers, and enforcers to remain well informed of the relevant building codes. Especially when federal, state, and local interpretations, adoptions, and enforcement vary. A brief history of the code development in the USA explores the formation of various building codes in regards to the occupants’ safety, health, well-being, and environmental issues.
