For buildings exceeding what height are construction documents required to indicate materials for fire-resistance rating?

In North Carolina, and generally in many building codes, construction documents must specify materials for fire-resistance ratings for buildings exceeding a certain height. The correct answer is that this requirement applies to buildings that are 2 stories or more.

When a building exceeds 2 stories, it presents increased risks for fire spread and evacuation. Code regulations mandate that the materials used in the construction of such buildings meet specific fire-resistance ratings to ensure occupant safety and minimize the risk of fire. This includes specifying wall assemblies, floors, and ceilings that possess adequate fire-resistance traits to withstand potential fire incidents.

This requirement is critical for ensuring the structural integrity of a building in case of a fire and facilitating the safe egress of occupants. Facilities that are taller need proper documentation and adherence to specific fire safety codes, which emphasizes the importance of clear guidelines in the construction documents.
