Building Uses

From Architect Wiki

Buildings, and sometimes portions of buildings, are organized into classifications based on the use or activities planned for the space. These are called Occupancy Groups. The groups are used to determine the life-safety requirements for a particular space.

See Occupancy Classification for more detailed information on specific categories.
