Fire Inspection Frequency by System: The Complete 2026 Schedule
Every fire protection system in your building runs on its own clock. Here is a plain-English schedule summarized from the NFPA standards most jurisdictions enforce.
1.Fire sprinklers (NFPA 25)
Quarterly inspection of alarm devices, valves, and the fire department connection; annual inspection and main drain test; 5-year internal pipe assessment and gauge replacement or calibration.
2.Fire alarm (NFPA 72)
Visual inspections and annual functional testing of most devices, with smoke detector sensitivity testing on a recurring cycle and batteries tested and replaced per the standard.
3.Portable extinguishers (NFPA 10)
Monthly quick checks by building staff, annual maintenance by a certified technician, plus periodic internal maintenance and hydrostatic testing based on extinguisher type.
4.Kitchen hood suppression (NFPA 96 / 17A)
Suppression system service every six months. Exhaust system cleaning frequency depends on cooking volume — from monthly for solid-fuel cooking to annually for low-volume kitchens.

6.Backflow preventers
Typically tested annually by a certified tester, as required by the water purveyor and NFPA 25.
7.Emergency and exit lighting (NFPA 101)
Monthly 30-second functional test and an annual 90-minute test, with written records.
8.Fire doors (NFPA 80)
Annual inspection and testing of fire-rated door assemblies, with documented results.
Put every system on one master calendar. Missed intervals — not failed equipment — are the most common reason buildings get cited.
