Currently, there are five occupancy classifications of detention facilities, depending upon their level of restraint:

-Use condition 1: Free movement is permitted within the building from smoke compartment to smoke compartment as well as to the exterior.
-Use condition 2: Free movement is permitted within the building from smoke compartment to smoke compartment.
-Use condition 3: Free movement is permitted within the building within a smoke compartment; movement to other areas is by remote control release.
-Use condition 4: Free movement is permitted within an occupied space within a smoke compartment; movement to other areas of the smoke compartment or other smoke compartments is by remote control release.
-Use condition 5: Free movement is restricted from the occupied space; manual release is necessary to allow movement from the occupied space to other areas of the smoke compartment or other smoke compartments.

Taxpayers generally have the following characteristics:

-They most often are of ordinary (Type 3) construction, usually with brick bearing walls and wood joist roof members.
-They commonly are one story in height, although two story variety can be found in many jurisdictions with apartments on the second and third floor.
-Depending on the region, many taxpayers can have full or partial basements.
-They usually are limited to approximately 6-10 small stores (or other commercial establishments).

Strip malls have the following characteristics:

-They may be of noncombustible, ordinary, or even wood frame construction (Types 2, 3, and 5 construction).
-When of noncombustible construction, strip malls have exterior walls of concrete block or concrete tilt walls with steel bar joist roof members and a metal deck supporting a built up roof.
-Contemporary ordinary construction strip malls use concrete block for exterior walls and solid wood joists or lightweight trusses to support a wood roof deck.
-Older ordinary construction strip malls may have large bowstring trusses.
-Some smaller strip malls may be built entirely of wood frame construction.
-Nearly all strip malls are one story, although a two story strip mall occasionally may be encountered.
-Based on region, strip malls may or may not have basements.
-They usually are larger than the taxpayers and may have as many as 15-20 small stores and a large anchor store or two.
-Strip malls usually have greater store depth than taxpayers. Strip mall anchor stores, such as supermarkets, may be more than 150 feet deep.
