A practical guide to IBC Section 907 and IFC fire alarm requirements — which occupancies require fire alarm systems, what triggers automatic detection vs. manual-only systems, and how sprinkler systems affect fire alarm requirements.
Fire alarm requirements in the United States come from two primary model codes: the International Building Code (IBC), which governs new construction and major renovations, and the International Fire Code (IFC), which governs ongoing operations and existing buildings. Most jurisdictions adopt both, with local amendments. NFPA 72 governs how fire alarm systems are designed and installed — IBC and IFC govern when they are required.
