Which code is primarily referenced for fire-resistive construction requirements?

The International Building Code (IBC) is primarily referenced for fire-resistive construction requirements because it provides the comprehensive set of regulations governing building design and construction, including standards for fire safety. The IBC includes specific provisions regarding the materials, design, and methods of construction that are intended to prevent the spread of fire and ensure that buildings can withstand fire exposure.

Fire-resistive construction is critical for protecting occupants, emergency responders, and property by establishing how long various building elements, such as walls, floors, and roofs, can withstand fire without failing. The IBC outlines fire-resistance ratings, construction types, and occupancy classifications, making it essential for fire safety compliance.

While other codes like the National Fire Protection Association Code and the Uniform Fire Code address aspects of fire safety, they do not provide the same level of detailed construction requirements as the IBC. The National Electrical Code focuses on electrical systems and safety rather than fire-resistive construction. Therefore, the International Building Code is the correct reference for fire-resistive construction requirements.
