Part IV‒Appendices
To identify the primary uses of buildings, structures and portions of buildings and structures; to identify risk factors associated with these uses; and to facilitate design and construction in accordance with other provisions of this code. These preliminary assumptions must be documented and verified as valid in any particular case.
In determining the primary use and occupancy classification of a building, structure or portion of a building or structure, the following shall be considered.
The principal purpose or function of the building or structure.
The hazard-related risk(s) to the users.

1. In determining the principal purpose or function of the building or structure, the use and occupancy classifications found in the International Building Code shall be used.

2. In determining the hazard-related risk(s) to users of buildings and structures, the following shall be considered:

2.1. The nature of the hazard, whether it is likely to originate internal or external to the structure, and how it may impact the occupants, the structure and the contents.

2.2. The number of persons normally occupying, visiting, employed in or otherwise using the building, structure or portion of the building or structure.

2.3. The length of time the building is normally occupied by people.

2.4. Whether people normally sleep in the building.

2.5. Whether the building occupants and other users are expected to be familiar with the building layout and means of egress.

2.6. Whether a significant percentage of the building occupants are, or are expected to be, members of vulnerable population groups such as infants, young children, elderly persons, persons with physical disabilities, persons with mental disabilities or persons with other conditions or impairments that could affect their ability to make decisions, egress without the physical assistance of others or tolerate adverse conditions.

2.7. Whether a significant percentage of building occupants and other users have familiar or dependent relationships.
Buildings shall be classified in accordance with the International Building Code and as modified by applying the risk considerations in Section A102.1.2.
A building, structure or portion of a building or structure in which persons gather for purposes such as civic, social or religious functions, recreation, food and drink consumption, or awaiting transportation. Unless otherwise modified under a specific sub-use classification, occupants, visitors and employees shall be assumed to be awake, alert, predominantly able to exit without the assistance of others, and unfamiliar with the building or structure. Vulnerable populations of many types may be expected to be present; however, the buildings are normally occupied for only short periods of time. It shall be assumed that:

1. Risks of injury and health assumed by occupants and visitors during their use of the building or structure are predominantly involuntary.

2. Public expectations regarding the protection afforded those occupying, visiting or working in an assembly building, structure or portion thereof are high.
Assembly uses, usually with fixed seating, intended for the production and viewing of the performing arts or motion pictures.

Assembly uses intended for worship, recreation or amusement, and other assembly uses not classified elsewhere in Use Group A.
Assembly uses intended for viewing of indoor sporting events and activities with spectator seating. It may be assumed that some portion of the population within this use group will be consuming alcohol, that loud and distracting sounds will be present and that flashing lights may be present under normal conditions.
