What Michigan’s Commercial Fire Door Requirements Actually Cover
Michigan enforces the International Building Code (IBC) alongside the NFPA 80 Standard for Fire Doors and Other Opening Protectives. These standards define which openings require a fire-rated door assembly, what fire rating that door must carry (commonly 20-minute, 45-minute, 60-minute, or 90-minute ratings), and exactly what hardware is permitted on those assemblies. A fire door assembly includes the door, the frame, the hardware, and any glazing. All components must be tested and listed together. Swapping out one piece for a non-rated replacement can void the entire assembly’s rating, even if the door itself is perfectly intact.
What Hardware Is Allowed on a Fire Door?
Fire door hardware is tightly regulated under NFPA 80, and not every lock or closer on the market is approved for fire door use. Hinges, latches, closers, and exit devices must all carry a fire listing from a recognized testing laboratory such as UL or Intertek. Panic hardware and push bars must be fire-rated models that allow free egress while maintaining the door’s ability to close and latch automatically. Our commercial door hardware services include installation and replacement of code-compliant components for fire-rated assemblies.
Common hardware violations we encounter include:
- Non-listed surface bolts installed on a pair of fire doors
- Coordinators that are not fire-rated
- Exit devices without a fire listing
- Hinges replaced with standard, non-rated versions
If you are unsure whether the hardware on your doors meets current standards, that is worth finding out before your next inspection.
Are Annual Fire Door Inspections Required in Michigan?
Yes. NFPA 80 requires that fire door assemblies be inspected and tested at least once per year by someone with knowledge of fire door standards. The inspection must confirm:
- The door closes and latches fully from the open position without being pushed
- All hardware is present and functioning
- There are no holes or breaks in the door or frame
- Clearances between the door and frame fall within allowed limits
Records of each inspection must be maintained and made available to the authority having jurisdiction, which in Michigan typically means the local fire marshal or building inspector. Failing to document inspections is treated the same as failing to perform them.
How Do Door Closers Factor Into Fire Door Compliance?
A self-closing mechanism is required on virtually every fire door. The closer must be strong enough to pull the door fully shut and latch it from any open position, including when the door is held open at 90 degrees. Closers that are worn, improperly adjusted, or set to too slow a speed are one of the leading causes of fire door failures during inspections. We handle door closer installation and repair for commercial properties throughout Oakland County and install closers that meet the force and timing requirements under NFPA 80. A closer that was working fine five years ago may no longer meet current requirements if it has been adjusted or worn down over time.
What Happens If a Fire Door Is Out of Compliance?
Non-compliant fire doors can result in failed building inspections, fines, and in serious cases, orders to cease operations in the affected area. Insurance carriers may use documented non-compliance as grounds to deny fire-related claims, which creates significant financial exposure. Beyond the legal and financial risk, a fire door that does not function correctly is a direct threat to the people inside the building. Addressing these issues proactively is far less costly than dealing with the fallout after an inspection or an incident.
