A fire door only works if it closes, latches, and holds back fire and smoke long enough for people to get out. That’s the whole job. When a fire door fails inspection, it’s usually because something small got ignored for months, a gap that grew, a label that got painted over, a closer that stopped pulling the door shut all the way.
NFPA 80, the Standard for Fire Doors and Other Opening Protectives, requires an annual inspection and test for every fire door assembly in a commercial building NFPA, “Fire Doors and NFPA 80 FAQs,” 2025. Doors also get inspected right after installation, before they ever see daily use NFPA, 2025. If you manage a commercial building in Broward County, this inspection isn’t optional and it isn’t a formality. Fire marshals check for it, and insurance carriers ask about it after a loss.
This article covers what the inspection actually looks at, what fails most often on real buildings, and how to fix problems before an inspector finds them.
What NFPA 80 Requires
NFPA 80 requires that a qualified person, someone who understands the door’s operating components and the type of fire door being tested, perform the inspection NFPA, 2025. That inspector can be an employee of the building owner or a third party, as long as the AHJ (authority having jurisdiction, usually the local fire marshal) accepts their credentials NFPA, 2025.
The standard lists a series of items that must be checked on every fire door assembly during the annual inspection. According to NFPA’s own summary of the standard, inspectors confirm NFPA, 2025:
- Labels are visible and legible
- No damage to the door, frame, or hardware
- No broken or missing parts
- Clearances around the door are within limits
- Any signage on the door is code-compliant
- The door closes and latches fully under an operational test
The door must stay operable at all times, it has to open, close, and latch without assistance NFPA, 2025. Wedging a fire door open, propping it with a chair, or disabling a closer defeats the entire assembly, and NFPA 80 prohibits it outright NFPA, 2025.
What Actually Fails on Real Buildings
We inspect and service fire door hardware on commercial buildings across Hollywood, Fort Lauderdale, and Pembroke Pines. The same handful of problems show up over and over.
Clearance gaps that grew over time
Every fire door assembly has an allowed clearance range around the door, the gap between the door and the frame, and the gap at the bottom. Doors settle. Hinges wear. Frames shift slightly after years of use. A gap that started within spec can widen past the allowed limit without anyone noticing, because nobody measures it day to day.
Once a gap is out of tolerance, smoke and flame can pass around the door faster than the rating assumes. The fix is usually adjustment, resetting hinges, shimming the frame, or in worse cases replacing a warped door.
Missing or painted-over labels
The label on a fire door is not decoration. It’s the proof that the door, frame, or window was tested and listed by a certification agency acceptable to the AHJ NFPA, 2025. The label has to show the manufacturer’s name, the certification agency’s mark, the door’s rating, the fire test standard it was tested to, and in some cases the temperature rise data from the listing test NFPA, 2025.
Painting crews repaint hallways and stairwells all the time, and fire door labels get hit along with everything else. NFPA 80 requires labels to stay legible and prohibits removing, defacing, or obscuring them while the door is in service NFPA, 2025. A label can technically be painted over and still pass if it remains readily visible and legible, for instance, an embossed label where the raised lettering still reads through a thin coat, but NFPA itself advises against painting fire door labels at all NFPA, 2025. In practice, most painted-over labels fail inspection because the lettering is no longer readable.
If a label is missing or illegible and can’t be salvaged, the rating isn’t automatically void, NFPA 80 allows the rating to be verified through other means the AHJ accepts, like a field inspection service or documentation from a certification service NFPA, 2025. That process takes time and costs money. It’s cheaper to protect the label in the first place, tell painting crews to mask it, or replace the door if the label is already gone.
Damaged gaskets and seals
Smoke seals and intumescent gaskets around the door frame are part of the listed assembly. When they crack, peel, or get torn off during moves and deliveries, the door may still close and latch fine, but the smoke-sealing function is compromised. This kind of damage is easy to miss on a quick walk-through because the door looks fine until you look at the frame edge closely.
Failed latch engagement
A fire door has to latch, not just close. Doors get slammed, closers get knocked out of adjustment, strikes wear down, and eventually the latch stops fully engaging, the door looks shut but a firm push opens it. This is one of the most common fails during an actual operational test, because closer adjustment drifts gradually and nobody notices until someone tests it under real conditions.
Fire Door Ratings
Fire doors carry a rating in minutes, the length of time the assembly is designed to hold back fire in a listing test. Common ratings on commercial buildings include 20, 45, 60, and 90 minutes, and the required rating for a given opening depends on the fire resistance rating of the wall or partition the door sits in NFPA, 2025. To determine what rating a specific opening needs, NFPA 80 points to tables in codes like NFPA 101 that cross-reference the wall assembly’s rating to the required opening protection NFPA, 2025. A stairwell door in a high-rise and a corridor door in a strip mall office won’t necessarily carry the same rating, even if they look similar.
What Happens If a Door Fails Inspection
What is clear: NFPA 80 requires that deficiencies found during inspection get corrected without delay, and the door has to remain operable and code-compliant in the meantime. A building that can’t produce inspection records, or that has known deficiencies left unaddressed, is exposed if a fire marshal does a walk-through or if there’s ever a fire and an insurance investigation follows.
Getting Ready for Inspection
The best time to fix a fire door problem is before the inspector shows up. A few things a building manager can check between annual inspections:
- Walk hallways and stairwells and look at every door label, is it visible, legible, not painted over?
- Check that doors close fully and latch on their own without being pushed
- Look at the gap around each door for obvious daylight or unevenness
- Confirm nothing is wedging or propping a fire door open
- Check gaskets and seals along the frame for tears or gaps
If any of that turns up a problem, get it corrected before the annual inspection date, not after.

The Full Inspection Checklist
The items above are the ones that fail most often, but the annual inspection under NFPA 80 covers the whole assembly. A complete inspection of a swinging fire door typically looks at all of the following:
- Labels on the door and frame are present and legible.
- There are no open holes or breaks in the door or frame surfaces.
- Glazing, vision light frames and glazing beads are intact and securely fastened.
- The door, frame, hinges, hardware and noncombustible threshold are secured, aligned and in working order, with no visible signs of damage.
- No parts are missing or broken.
- Clearances at the door edges and bottom are within the allowed limits.
- The self-closing device operates, closing the door completely from the fully open position.
- On pairs of doors with an astragal, the coordinator closes the inactive leaf before the active leaf.
- Latching hardware operates and secures the door when it is closed.
- No auxiliary hardware has been added that interferes with the door’s operation.
- No field modifications have been made that would void the label.
- Gasketing and edge seals, where required, are present and intact.
- Meeting edge protection, where required, is in place.
Each assembly gets the same review, and the results are recorded for that specific door. Inspection records are expected to be kept and made available to the authority having jurisdiction, and NFPA 80 calls for them to be retained for at least three years.
Hardware That Does Not Belong on a Fire Door
A large share of fire door problems come from hardware that was added after installation by someone trying to solve a practical problem. Common examples include:
- Kick-down door holders. These hold the door open and defeat the closer. They are not permitted on fire doors.
- Hook and eye latches or slide bolts. Added for extra security or to keep a door shut, they can interfere with the listed latch and create an unapproved modification.
- Surface-mounted locks from a hardware store. If the hardware is not listed for use on fire doors, it does not belong there.
- Dogging on panic hardware. Ordinary exit devices can be “dogged,” meaning the latch is held retracted so the door pushes open without latching. Fire exit hardware is not supposed to allow mechanical dogging, because the door must latch when it closes.
- Extra holes. Old holes left behind from removed hardware, signage screws driven through the door or holes drilled for a new device all need to be addressed with methods that keep the door compliant.
When a door needs to stay open for traffic or ventilation, the compliant solution is a listed hold-open device that releases the door when the fire alarm activates or when smoke is detected, not a wedge or a kick-down stop.
Electrified Hardware on Fire Doors
Access control has made its way onto many fire doors, especially stairwell and corridor doors in office buildings and condos. Electrified hardware on a fire door has to be listed for that use and has to preserve positive latching. That is why electric strikes used on fire doors are fail-secure. When power is removed, the strike stays locked and the latch still holds the door closed. A fail-safe strike would release the latch when power is lost, which would leave the door unlatched during a fire when it matters most.
Electrified exit devices and locks with electric latch retraction can also be used on fire doors when they are listed and configured to allow the latch to project and hold when the fire alarm activates or power is lost. Any wiring holes and power transfer hardware should be made using methods allowed by the door manufacturer and the listing.
Rolling Fire Doors in Warehouses
Warehouses, distribution centers and mixed-use buildings often have rolling steel fire doors in openings between sections of the building or at firewalls. These doors normally stay open and close automatically when a fusible link melts or when a detector triggers a release device. They are also covered by NFPA 80 and need an annual inspection and drop test, which confirms the door actually closes fully when released.
Common problems with rolling fire doors include inventory, pallets or racking stored in the path of the curtain, damaged guides that cause the curtain to bind, and fusible links that have been replaced with wire or other improvised fasteners. Keeping the area under the door clear is one of the simplest and most important things warehouse staff can do.
Field Modifications and When to Stop
NFPA 80 allows certain limited modifications to fire doors in the field, such as some holes for surface-applied hardware and some preparation for specific hardware, as long as they follow the standard and the manufacturer’s instructions. Larger changes, like cutting in a new vision panel, adding a louver or changing the lock type in a way that requires significant cutting, generally require approval from the listing agency or replacement with a door that was manufactured with those features.
If you are not sure whether a change is allowed, ask before cutting or drilling. Once a door has been modified improperly, correcting it can be difficult and may require a new door.
Why Closers Drift on Fire Doors
The closer is the part of a fire door that does the most work and changes the most over time. Hydraulic fluid thins in heat, and many South Florida stairwells and service corridors are not air conditioned, so a closer adjusted on a cool morning can behave differently on a hot afternoon. Staff and tenants also tend to loosen closers on doors they find heavy, without realizing the door now fails to latch. When a closer has been adjusted repeatedly and still does not bring the door fully closed and latched from every open position, replacement is usually more reliable than another adjustment. The replacement closer should be sized and set for the door’s weight, width and location, including any pressure differences in stairwells.
Glass in Fire Doors
Vision panels in fire doors must use glazing listed for fire-rated openings and must be installed in listed frames or with listed glazing materials. A cracked or broken vision panel is a deficiency, and so is a replacement panel made from ordinary glass. When a vision panel breaks, the replacement has to match the listing for that door. If you are not sure what type of glass the door requires, check the label on the door and the marking etched on the existing glass before ordering a replacement.
Fire Doors Versus Smoke Doors
Some doors are intended mainly to control the spread of smoke rather than fire. Smoke doors are addressed in NFPA 105, which also includes requirements for inspection and testing. These doors often have gasketing and bottom seals that limit air leakage. A door can be both fire rated and used for smoke control. When scheduling an inspection, ask for a list showing which doors are fire rated, which are smoke doors and which are both, so each one is checked against the right requirements.
Preparing Staff and Vendors
Many fire door problems are introduced by people who do not realize the doors are special. A short briefing for building staff and outside vendors can prevent a lot of repairs. Explain which doors are fire rated, how to recognize a fire door label, and what not to do: no propping, no wedges, no painting over labels, no drilling or screwing signs into the door, and no removing closers.
Movers, flooring installers and IT contractors deserve special attention. Movers tend to prop doors and damage edges and seals. Flooring changes can alter the gap under the door. Cabling contractors sometimes drill through fire doors or frames. Reviewing doors after these projects helps catch damage while the vendor is still available to correct it.
Planning Around the Annual Inspection
For larger buildings, the annual inspection goes more smoothly with some preparation:
- Create or update a door schedule that lists each fire door by number and location.
- Mark doors on a floor plan so the inspector can find them quickly.
- Make keys or access available for all rooms, stairwells, mechanical spaces and storage areas.
- Pull last year’s records to see which doors had deficiencies and whether they were corrected.
- Notify tenants that doors in their spaces will be inspected and tested.
After the inspection, prioritize repairs based on risk. Doors that do not close or latch, doors blocked open and doors with missing hardware should be addressed first, followed by clearance problems, seal damage and label issues. Keep the repair records with the inspection report so the next inspection can confirm each deficiency was resolved.
