Which chapter of the IBC focuses on Use and Occupancy classification?

The chapter that focuses on Use and Occupancy classification in the International Building Code (IBC) is Chapter 3. This chapter outlines the different classifications of buildings based on how they are used, which is crucial for determining the appropriate fire safety measures, structural requirements, and other critical factors in building design and construction.

Understanding the Use and Occupancy classifications is vital for fire protection professionals as it impacts fire alarm system design, including the type and placement of fire alarm equipment, emergency egress requirements, and overall safety strategies tailored to specific use scenarios. Each classification has different implications for how a building should be constructed and maintained to ensure the safety of its occupants.

Chapter 4 deals primarily with special Requirements, while Chapter 7 covers fire and smoke protection features. Chapter 9 discusses the basics of building construction, but it does not specifically focus on classifications related to use and occupancy. This differentiation is critical for those involved in designing and implementing fire protection measures within building codes.
