Today, U.S. building codes are primarily developed by which organizations?

The development of U.S. building codes is primarily the responsibility of organizations that are dedicated to setting standards for safety, construction, and fire prevention. The National Fire Protection Association (NFPA) is renowned for its rigorous codes and standards designed to minimize the risk of fire and improve fire prevention practices. This organization is influential in shaping fire safety regulations that impact building design and construction.

The International Code Council (ICC) is another pivotal organization that develops comprehensive codes covering various aspects of building construction and safety, including residential and commercial structures. The ICC's codes are widely adopted at the state and local levels in the U.S., ensuring consistency and safety across different jurisdictions.

Together, the NFPA and ICC collaborate to ensure that building codes reflect the latest safety practices, technological advancements, and risk assessments, making them crucial for public safety and welfare. Hence, identifying the NFPA and ICC as the primary developers of building codes accurately reflects their significant roles in the field.
