"All 50 states and the District of Columbia have adopted the I-Codes at the state or
jurisdictional level. Many federal agencies, Guam, Puerto Rico and the U.S. Virgin Islands use or
reference the I-Codes. Outside of the U.S., the I-Codes are the basis for the Abu Dhabi International
Building Codes, the regional Caribbean Building Standard, the Mexico Residential Building Code, the
Haitian National Code, the Honduras Building Code, Jamaica’s construction codes, Georgia’s building
safety codes and the Saudi Building Code."
