Which code regulates building design and safety standards?

The International Building Code (IBC) is the correct regulation that governs building design and safety standards. It provides a comprehensive set of guidelines for the construction and occupancy of buildings, addressing aspects such as structural integrity, fire prevention, safety in emergency situations, accessibility, and sanitation. The IBC is used widely across the United States and is frequently adopted by local jurisdictions to ensure that buildings meet essential safety and performance criteria.

This code encompasses not only regulations for commercial buildings but also includes historic buildings, residential buildings, and mixed-use developments. The IBC is essential for architects and builders as it helps ensure that their designs comply with the latest safety and health standards, promoted by the International Code Council (ICC).

In contrast, the other options are more specialized in scope. The International Residential Code primarily focuses on residential buildings, the American National Standards Institute develops consensus standards for various industries but not building codes directly, and the National Electric Code specifically governs electrical safety in buildings. Thus, while each of these codes and standards contributes to overall safety and compliance in specific areas, the International Building Code is the primary source for comprehensive regulations on building design and safety.
