The International Building Code (IBC) classifies every building primarily based on what two criteria?

The International Building Code (IBC) classifies buildings based on two main criteria: type of construction and occupancy type and use. This classification is essential because it determines the safety, structural integrity, and overall design requirements for buildings, ensuring they meet necessary codes and standards for various conditions and uses.

The type of construction refers to the materials and techniques used in the building's structure, which can significantly affect fire resistance, durability, and other safety considerations. Different types of construction are categorized to reflect varying levels of safety and performance.

Occupancy type and use refer to how the building will be occupied and the activities that will take place inside it. This is crucial for determining appropriate safety measures, such as fire exits, emergency plans, and accessibility features, tailored to the specific needs of the occupants.

By classifying buildings in this way, the IBC ensures that buildings are designed, constructed, and maintained in a manner that maximizes safety and compliance with local regulations.
