What is defined as occupiable space?

Occupiable space is defined as a space intended for human activities. This definition encompasses areas where individuals can engage in various functions, such as living, working, or other activities that require human presence. The concept of occupiable space is vital in building codes and standards because it relates to safety, health, and accessibility requirements that must be met to ensure that the space can be utilized effectively and safely by occupants.

In contrast, spaces designated solely for storage, mechanical systems, or areas that are not meant for occupation, such as unoccupied basements, do not meet the criteria for being classified as occupiable. These types of spaces do not provide the necessary amenities or conditions that would allow for human activities. Therefore, the understanding of occupiable space plays a significant role in various aspects of building design and safety considerations in the mechanical code context.
