Under NFPA 101, the building owner’s responsibilities encompass more than simply meeting the code on paper. The owner must ensure ongoing life safety by maintaining all life safety systems (such as fire alarms, automatic sprinklers, smoke detectors, fire doors, exit signs, emergency lighting, and standpipes) in operable condition, and by keeping means of egress clear and functional. They must provide training to occupants and staff on safety procedures and ensure that emergency plans are in place and practiced through drills. In addition, the owner is responsible for verifying that fire protection features are continuously functioning and properly maintained, which includes arranging for regular inspections, testing, and maintenance. Therefore, the statement that includes code compliance, maintenance of life safety systems, training, emergency plans, and ongoing verification of fire protection features best describes the scope.

A building designated as historically significant is called a historic building. This status is given by the local authority having jurisdiction to recognize its preservation needs, while still keeping occupants safe. In NFPA 101, historic buildings can receive special allowances or review under historic-preservation provisions, allowing modifications that protect the building’s character but require life-safety protections to be maintained or justified for approval. The other terms refer to different concepts: a high-rise building is defined by its height SAMPLEand has specific egress and fire protection rules; a common path of travel is the shared portion of the exit access that leads to an exit; and a change of use means altering the occupancy classification, which triggers different life-safety requirements.

The principle here is limiting how smoke and heat move through hidden spaces by using a continuous barrier. This is called a draft stop—the uninterrupted membrane placed within concealed spaces (like ceilings, under floors, or attic/ceiling cavities) to subdivide them and slow the spread of fire and smoke. A fire door, while it helps maintain a fire barrier, is a door installed in a barrier and isn’t the continuous membrane that subdivides concealed spaces. A court is an open or courtyard area in a building, not a barrier in concealed spaces. A dwelling unit is a living space and not a barrier used to block smoke travel.

In NFPA 101, how a building is classified for life safety depends on its occupancy classification, which groups spaces by the level of risk and the protections required. When that classification changes for all or part of a structure, the term used is Change of Occupancy Classification. This reflects a shift in the fundamental protection needs—egress, fire resistance, detection and suppression—based on the new, higher or different occupancy group. Change of Use describes a different idea: it’s about what the space is being used for, which can influence loads or means of egress but doesn’t by itself imply a reclassification of the occupancy groups. The other options—Alteration of Building Code and Structural Refit—aren’t standard terms used to describe this concept in life safety contexts.
