What is meant by "occupancy classification" in building codes?

"Occupancy classification" in building codes refers to a categorization based on the intended use of a building or space within a building. This classification is crucial because it helps to establish the requirements for safety, structural integrity, fire protection, and accessibility based on how the space will be utilized. Different types of occupancy—such as residential, commercial, industrial, or assembly—carry specific regulations that are tailored to mitigate the risks associated with those uses.

For example, a residential occupancy may have different fire safety requirements compared to a commercial assembly space, reflecting the number of occupants and the activities conducted within those spaces. This classification also guides compliance with design standards, ensuring that buildings are safe for their intended users. Understanding occupancy classification is fundamental for architects and builders to ensure they meet legal and safety standards in their projects.
