I-Codes continue to be the code of choice across the U.S.

With a host of adoptions across the country, I-Codes continue to be the most widely adopted and enforced building safety codes in the United States.

The California Building Standards Commission took action that will allow state agencies to move forward with the adoption of building codes, including the International Building Code, the International Fire Code and the International Residential Code, when the state's building codes are updated. State agencies will bring proposed code amendments back to the Building Standards Commission for approval.

"The decision sets a course that will help ensure the highest level of building and fire safety in places where Californians live, work and play," said James Lee Witt, CEO of the International Code Council. "We applaud the California Building Standards Commission for undertaking a detailed analysis of the codes and making public safety interests its first priority."
