When classifying major occupancy, which factor is primarily considered?

The classification of major occupancy is fundamentally based on the intended use of the space. This factor is crucial because it directly influences the safety, design, and regulatory implications of a building. Different types of occupancies, whether they are residential, assembly, educational, industrial, or others, impose distinct requirements regarding fire safety, structural integrity, and accessibility.

Understanding the intended use helps in determining necessary building codes, the level of fire protection needed, and how occupants will interact with the space. For instance, a building designated for assembly purposes (like theaters or concert halls) has different safety measures compared to a residential building.

While building age, architectural style, and environmental impact are relevant considerations in the broader context of building design and sustainability, they do not fundamentally affect the classification of major occupancy. The most pertinent aspect is always the primary function of the building space as defined by its intended use. This classification ensures that the building adheres to appropriate safety standards and regulations reflecting the nature of its activity.
