The provisions of this chapter shall govern maintenance of the materials, systems and assemblies used for structural fire resistance and fire-resistance-rated construction separation of adjacent spaces to safeguard against the spread of fire and smoke within a building and the spread of fire to or from buildings.
Where any components are not maintained and do not function as intended or do not have the fire resistance required by the code under which the building was constructed or altered, such components or portions thereof shall be deemed unsafe conditions. Components or portions thereof determined to be unsafe shall be repaired or replaced to conform to that code under which the building was constructed or altered.
The required fire-resistance rating of fire-resistance-rated construction, including walls, firestops, shaft enclosures, partitions, smoke barriers, floors, fire-resistive coatings and sprayed fire-resistant materials applied to structural members and joint systems, shall be maintained. Openings made therein for the passage of pipes, electrical conduits, wires, ducts, air transfer and any other reason shall be protected with approved methods capable of resisting the passage of smoke and fire. Openings through fire-resistance-rated assemblies shall be protected by self- or automatic-closing doors or approved construction meeting the fire protection requirements for the assembly.
703.3.1 
Fire blocking and draft stopping.
Required fire blocking and draft stopping in combustible concealed spaces shall be maintained to provide continuity and integrity of the construction.
703.3.2 
Smoke barriers and smoke partitions.
Required smoke barriers and smoke partitions shall be maintained to prevent the passage of smoke. Openings protected with approved smoke barrier doors or smoke dampers shall be maintained in accordance with NFPA 105.
703.3.3 
Fire walls, fire barriers, and fire partitions.
Required fire walls, fire barriers, and fire partitions shall be maintained to prevent the passage of fire. Openings protected with approved doors or fire dampers shall be maintained in accordance with NFPA 80.
Opening protectives shall be maintained in an operative condition in accordance with NFPA 80. The application of field-applied labels associated with the maintenance of opening protectives shall follow the requirements of the approved third-party certification organization accredited for listing the opening protective. Fire doors and smoke barrier doors shall not be blocked or obstructed, or otherwise made inoperable. Fusible links shall be replaced whenever fused or damaged. Fire door assemblies shall not be modified.
703.4.1 
Hold-open devices and closers.
Hold-open devices and automatic closers shall be maintained. During the period that such a device is out of service for repairs, the door it operates shall remain in the closed position.
703.4.2 
Door operation.
Swinging fire doors shall close from the full-open position and latch automatically. The door closer shall exert enough force to close and latch the door from any partially open position.
The hanging and displaying of salable goods and other decorative materials from acoustical ceiling systems that are part of a fire-resistance-rated horizontal assembly shall be prohibited.
Interior vertical shafts, including stairways, elevator hoistways and service and utility shafts, which connect two or more stories of a building shall be enclosed or protected. New floor openings in existing buildings shall comply with the International Building Code.
Where openings are required to be protected, opening protectives shall be maintained self-closing or automatic-closing by smoke detection.
Existing building area currently protected by automatic fire sprinkler systems shall be separated from an adjacent building area which is not protected by a fire sprinkler system by constructing an approved 2-hour fire-resistive rated fire barrier assembly(ies) and/or horizontal assembly(ies) in accordance with the Fire Barrier requirements in the currently adopted International Building Code. More restrictive requirements shall apply as required by the International Building Code.
