A fire door inspection in Alberta checks that every part of the door assembly still works the way it was listed to work: the label, the self-closing action, the latch, the gaps, the hinges, the hardware, the seals, and the absence of anything that stops the door from closing. NFPA 80, the fire door standard Alberta's building code requires fire doors to be installed to, calls for fire door assemblies to be inspected and tested at least annually, with written records. The Alberta fire code adds its own routine checks on top.
If you manage or own a commercial, multi-unit or institutional building in Calgary, that annual check is a recurring job, not a one-off. The sections below walk through what is looked at, what usually fails, what happens when a door does fail, and who is on the hook.
This guide is written for property managers and building owners. It explains the checks so you know what a good inspection covers and what a failed item means for your budget and your building. Code requirements apply per building and per job, so treat this as orientation and confirm specifics with your fire inspector, insurer or consultant.
A fire door assembly is the door, the frame, the hinges, the latch and closer, and every other component that together hold back fire and smoke. It is inspected as one unit because the fire rating belongs to the combination, not to the slab of steel alone. A good door in a bent frame, or with the wrong latch, no longer performs as listed.
That is why inspectors do not just look at the door face. A rated steel door in a hollow metal frame can look perfect and still fail because the closer is disconnected, a hinge screw is missing, or someone has propped it open for two years.
The rating is tied to the labels on the door and frame, which show the assembly was tested and listed. For how ratings work, what the labels mean and how steel and hollow metal fit into a fire separation, see our guides to fire-rated steel doors in Calgary and hollow metal doors and frames. This article assumes you have those doors and focuses on keeping them working.
Fire door assemblies should be inspected and tested at least once a year, and the results should be written down. That is what NFPA 80 calls for. The Alberta fire code also sets shorter intervals of its own: fire doors are checked daily to make sure they are closed (unless they are on an approved hold-open device), operated monthly, and the inspection and maintenance records are kept on the premises for two years.
The written record matters as much as the check itself. A fire inspector, an insurer or a buyer's due diligence team may ask to see it. A door that was checked but has no record is hard to prove was checked.
Some buildings choose to inspect more often than once a year. Doors in high-traffic stairwells, loading areas and corridors take more punishment than a door to a rarely used electrical room, and in a Calgary winter, frost heave, door swell and salt can change how a door sits and latches between one annual check and the next. If a door starts to drag, stick or slam, do not wait for the calendar.
Your fire inspector or consultant can tell you whether anything specific to your occupancy or building changes that schedule.
An annual inspection works through the assembly item by item: labels, door and frame condition, gaps, hinges, hardware, self-closing, latching, seals, glazing, and anything added or removed since the last check. Each item is marked pass or fail, and failures are written up so they can be fixed.
The core checklist looks like this:
The next sections take the checks that cause the most trouble one at a time.
The label on the door and the frame is the proof the assembly was built and listed as fire-rated. If it is missing, painted over until it is unreadable, or the door has been swapped for an unmarked one, an inspector cannot treat the assembly as rated.
Labels are usually a small metal plate or stamp on the hinge edge of the door and on the frame. They get lost in a few common ways: a repaint that covers them, a door that was cut down to fit a new floor, or a replacement slab that was never a rated door in the first place.
A missing label is rarely a quick fix. You usually cannot just add one on site, because the label is not a sticker you can reorder. The door or frame may have to be evaluated or replaced. If you are taking over a building, checking labels on every door in a fire separation is one of the most useful things you can do in the first month.
A fire door has to close fully every time, and the latch has to catch. Inspectors open the door partway and let go, then do it again from fully open, watching that it swings shut on its own and the latch engages without a push.
This is the most common single failure on fire doors. A door that stops an inch short, or rests against the frame without latching, will not hold back fire or smoke, however well the rest of it is built.
The usual causes are mundane. A closer arm has loosened or bent, the closer is leaking fluid, the spring force has drifted, or the latch bolt is dragging on a misaligned strike plate. Weather plays a part on exterior and stairwell doors, since changes in air pressure, cold and ice can stiffen closers and change how a door seats.
Closer adjustment is often an easy repair. A worn-out closer should simply be replaced with one suitable for the door.
Gaps around a fire door need to be small and even. The standard sets limits for the clearance at the head, the jambs and the bottom of the door, and an inspector measures them rather than judging by eye. Too tight and the door binds. Too wide and fire and smoke can pass.
Clearance limits are set out in NFPA 80, and the door's manufacturer and listing can matter too, so use the standard and your inspector for the exact figures instead of rounding off a number from memory.
Gaps drift over time. Hinges wear, doors sag, frames get knocked by carts and pallet jacks, and floor coverings get added that raise the finished floor. A door that was fine at installation can need adjusting within a few years in a busy building.
A visible gap that you can see light through, or a door that rubs the frame on one side and floats on the other, almost always points to hinge wear, a bent frame or a door that has dropped. Those are repairable if caught early, and they are a replacement conversation if the frame has been damaged.
Inspectors check that hinges are present, tight and appropriate, and that every screw is in place. Then they check that the latch, closer, handles, panic hardware and any other hardware are complete, working and listed for use on a fire door.
Hardware that looks fine can still be wrong. A lockset swapped in during a tenant fit-up, a surface bolt added to the door for security, or a closer from a hardware store that is not suited to the door can all take the assembly out of its listing.
Hardware problems tend to cluster in a few places:
Panic hardware on a fire door has to be fire exit hardware, listed for fire doors, which works for egress and still latches the door when released. If a stairwell or exit door will not latch after someone has pushed through, that is a failed item.
A field modification is anything done to a labelled door or frame after it left the factory, such as drilling for new hardware, cutting a hole for a vision panel or a mail slot, or trimming the edges. Unless the change is permitted by the door's listing, it can void the label and take the assembly out of its rating.
This is where well-meaning tenants and contractors cause the most trouble. A new access control reader needs a cable run, so someone drills through the door edge. A tenant wants a sign, so someone screws it on. A cut-out is made for a delivery slot. Each looks small and none of it is visible from the corridor.
Inspectors look for holes that should not be there, signs and plates fixed through the door skin, glazing that is not a listed fire-rated type, and repairs made with filler or tape that did not come from the manufacturer.
Some modifications can be done properly, but only by following the door manufacturer's or listing agency's allowed procedures. The safe default is to ask before anyone drills into a rated door. If you run a building with frequent tenant changes, a note in your fit-up rules that no one touches the fire doors without approval is cheap and effective.
A fire door that is propped open will not close in a fire. Wedges, rubber stops, tied-back doors and anything else holding a door open defeat the door entirely, so inspectors treat them as a fail every time they are found.
People prop doors for understandable reasons: carrying stock, moving furniture, getting some airflow, or because the closer is stiff and annoying. That is exactly why they are so common and why they matter.
If a door genuinely needs to stay open for traffic, and a hold-open is permitted at that location, the right answer is a hold-open device that releases and lets the door close in a fire, typically on a signal from the fire alarm or a detector, not a wedge. Electromagnetic holders wired to the alarm are the usual example. Some doors, such as exit stair doors in taller buildings, cannot have hold-opens at all. Your fire consultant can tell you what suits your building.
A common middle step is to fix the thing driving the propping. If the closer is too strong for the door to be usable, it can be adjusted within its range. If staff keep wedging a door because it is in the way of a delivery route, that is a layout conversation, not a discipline problem.
The failures that come up most often are doors that do not close and latch on their own, doors held open, missing or unreadable labels, gaps that are out of range, damaged or missing hardware, and unauthorized holes or modifications.
Roughly in order of how often they turn up on busy commercial properties:
Many of these are caught early by a monthly walk-through by building staff, who can spot a propped door or a closer hanging off its arm without a formal inspection. The annual inspection is then a confirmation and a record, not a surprise. If you are also tracking wear across steel doors generally, our piece on common steel door repairs in Calgary covers what to look for in between.
When a fire door fails, the failed items are written up and need to be corrected, not just noted. Adjustments and worn parts such as closers, hinges, latches and strike plates are usually repaired. A damaged labelled door often cannot be field-repaired and has to be replaced.
The line between the two comes down to the label. Replacing a worn closer or tightening a hinge leaves the listed assembly intact. Patching a dented door skin, filling a hole, or welding on a damaged frame generally does not, because the repair is not something the listing covers. A door with a hole cut through it for the wrong hardware, or a frame that has been bent by an impact, is more often replaced than rescued.
In practice, the decision looks like this:
Where a replacement is needed, the new door and frame should match the rating required at that location. For help weighing steel against other materials for your building, see our comparison of steel and aluminum commercial doors, and our note on signs you need to replace a commercial steel door.
The building owner is responsible for keeping fire doors maintained and in working order. A property manager typically carries the job out on the owner's behalf, which makes it a practical task for you, but responsibility for the building's fire protection stays with the owner.
For a condo corporation, a commercial landlord or a business that owns its premises, that means the annual inspection, the written records, and fixing failed items are the owner's to arrange and pay for. Tenants who prop doors or modify them can create the problem, but the assembly is part of the building.
Practical steps for a manager:
For questions about who in your situation holds what responsibility, and what your local fire inspector or insurer expects, ask them directly. Obligations differ by building type, occupancy and lease structure.
If an inspection has flagged a door, C Town Doors installs and repairs fire-rated steel and hollow metal doors in Calgary, and can replace a door that has failed inspection. Codes and ratings apply per job, so we look at each door and each location individually and fit what that opening needs.
Bring the inspection report if you have it. It shows which doors failed and why, which makes it quick to separate the closer-and-hinge repairs from the doors that have to be replaced.
