a. Existing buildings must comply with the sections identified as "Required" based on occupancy classification or use, or both, whichever is applicable.
(Amend Coun. J. 2-19-20, p. 14473, Art. V, § 17)
This section governs 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 structure, and the spread of fire to or from separate structures.
Where any components of a structure are not maintained and do not function as intended or do not have the fire resistance required by the code under which the structure was constructed or altered, such components are unsafe. Components determined to be unsafe must be repaired.
The required fire-resistance rating of fire-resistance-rated construction, including walls, firestops, shaft enclosures, partitions, smoke barriers, floors, fire-resistive coatings, sprayed fire-resistant materials applied to structural members, and fire-resistant joint systems, must be maintained. Such elements must be visually inspected annually by the owner and repaired where damaged, altered, breached, or penetrated. Records of inspections and repairs must be maintained by the owner. Where concealed, such elements are not required to be visually inspected unless the concealed space can be accessed by the removal or movement of a panel, access door, or ceiling tile or entry to the space.
(Amend Coun. J. 2-19-20, p. 14473, Art. V, § 19; Amend Coun. J. 10-7-20, p. 21791, Art. V, § 6)
