What Denver's code change means for your rolling fire doors

Denver adopted the 2025 Denver Building and Fire Codes, built principally on the 2024 family of international codes, effective December 31, 2025, and the city's own page states there are no exceptions for new project drawings submitted after that date. (Denver Building and Fire Code, checked September 18, 2026.)

The 2024 fire code edition added an explicit requirement aimed squarely at rolling steel fire doors: an annual inspection and test, performed by a trained rolling steel fire door systems technician, in accordance with the national fire door standard, with records maintained.

Here is the honest limit on what we can tell you. We could not confirm from the source documents we were able to read whether Denver amended, kept, or altered that specific section, so we are not citing a Denver section number for it, and nothing on this page decides whether the rule applies to your building. What we can say plainly:

• The requirement exists in the code edition Denver has moved to.
• Denver licenses fire doors as its own specialty category, separate from overhead doors.
• The offices that answer for your building are the Denver Fire Department Prevention Division and Denver Community Planning and Development.

Call them with your address and ask two questions: which inspection and testing requirements apply to our rated rolling doors, and what records do you expect to see. The provider and the issuing office confirm it; a web page cannot.

Is your door actually rated?

A rated rolling fire door is a listed assembly designed to close by itself in a fire and hold back fire and smoke for a stated period. It looks a lot like an ordinary coiling door from the floor.

Tells that it might be rated:

• A metal label on the guide, hood, or bottom bar with a listing mark and an hourly rating.
• A fusible link — a small soldered metal link in a cable, designed to melt at a set temperature and release the door.
• A release device, governor, or a drop-test tag on the hood.
• Its location: rated rolling doors sit in fire-rated walls separating occupancies or areas, and in openings between a warehouse and an office or between fire areas.

If none of those apply and it is on an exterior dock face, you are probably on the roll-up and rolling-steel door page instead. If you are not sure, say so on the call.

Do not test it to find out. Do not pull the link, trip the release, or cycle the door to see whether it drops. A rated door coming down unexpectedly is a hazard, and a drop test on a door with an unknown condition is not a DIY exercise.

What a drop test actually is

A drop test is a controlled release of the rated assembly to confirm two things: that the door closes fully under its own power with the normal means of operation disconnected, and that it can be reset and returned to normal service.

Two details worth knowing before you compare proposals, from published industry guidance on rolling fire door testing:

• The drop test is performed twice — once to verify operation, and once after reset to verify the door can be released again.
• The national fire door standard sets closing-speed limits for these assemblies: an average of not more than 24 inches per second and not less than 6 inches per second. A door that closes too fast is as much a finding as one that will not close.

Published industry guidance also warns about a contract point worth raising up front: components can fail during a drop test precisely because they are being tested, and a test proposal is usually priced as a test, not as a repair. Ask what happens — and what it costs — if the door fails mid-test. Get that answer before the technician is on site, not after.

What a provider will look at

What we cover on this page — and what we don't

In scope: rated rolling fire doors and fire shutters, fire-rated counter shutters, their release devices, fusible links, governors, curtains and guides. Repair, reset, inspection and drop-test enquiries, and the documentation that goes with them.

Not in scope: non-rated coiling doors (roll-up). Sectional doors (overhead). Swinging fire-rated pedestrian doors with closers and hardware. Fire alarm systems, sprinklers, smoke detection, and fire-suppression equipment. Fire-rated walls, dampers and penetrations. Residential. Parts-only supply.

What to say when you call

1. You call and describe the door and the facility location — and say you believe it is rated.
2. Your request may be shared with an independent commercial dock-and-door repair company.
3. That provider confirms availability, scheduling, pricing, and its own service terms.

Example wording — an example, not a real job:

"Our rolling fire door in Denver dropped and won't reset, and I can give you the address and the opening."

Useful, but not required: which opening it protects, the hourly rating if the label is visible from where you stand, when it was last tested, whether you have the previous report, and whether an inspector has already flagged it. You can call without any of it. Do not climb to read a label on a hood.

If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

What affects the price

We can't quote your exact repair from a web page. The price depends on the equipment, the fault, parts, and access. Here's what to ask before you authorize work.

• How many rated openings. Testing is usually priced per door, and quantity matters.
• Test only, or test plus repair. These are different line items. Ask which you are buying.
• What happens if it fails mid-test. Raise this before the visit. Published industry guidance specifically flags that components can fail under test and that this is usually outside the test price.
• Access. Doors high in a wall or over an active area need lifts and scheduling.
• Parts on a listed assembly. Replacement parts on a rated door have to be right for the listing, which narrows the options.
• Records and documentation. Ask what report you receive and in what form. That report is usually what an inspector wants to see.
• Reset versus repair. A door that dropped for a known, minor reason is a different job from one that dropped because something failed.
• Which kind of number it is — diagnostic fee, starting price, scoped fixed price, estimate, or final quote. Breakdown on the Denver hub page.

For the standard's testing requirements in general, see the national fire door drop test requirements reference.

Say it is rated and let the provider scope it.

The Denver rules that matter here

Denver licenses fire doors separately. The contractor licensing policy lists a Class D specialty for fire doors — to install and repair fire doors, distinct from the overhead door category. A company holding the overhead door classification is not automatically holding the fire door one. Ask which classification the company holds, and match it to where your building sits — Denver does not reciprocate licenses from other counties or states. (Denver Contractor Licensing, checked September 18, 2026. Contractor Licensing: 201 W. Colfax Ave., 2nd floor, (720) 865-2770, Mon–Thu 8–4, closed 12–1.)

Two offices, two questions. Denver Community Planning and Development handles building permits and licensing. The Denver Fire Department Prevention Division handles fire code enforcement and inspection expectations. For a rated door, the inspection and records question usually belongs to the fire side.

Outside Denver, the city or county that covers your parcel has its own adoption and its own fire authority. The Denver service area page lists which office covers each town. The absence of permit guidance here does not mean a permit is not required. The provider and the issuing office confirm it.

Where we take calls

Denver, Aurora, Commerce City, Thornton, Englewood and the rest of the ten-county metro, plus the towns just past those county lines, reviewed case by case. The independent provider confirms your facility address and whether it can take the job. Full list on the Denver service area page.

Questions about rolling fire doors in Denver

How often does a rolling fire door have to be tested?

The code edition Denver has moved to calls for annual inspection and testing of rolling steel fire doors by a trained technician, with records kept. Whether and exactly how that applies to your specific assembly is a question for the Denver Fire Department Prevention Division and Denver Community Planning and Development for a Denver building, or your local fire authority elsewhere. Ask them, and ask the provider what records you will receive.

Who is allowed to do the test?

The code language points to a trained rolling steel fire door systems technician, and Denver licenses fire door work as its own specialty. So there are two things to verify: that the individual is trained for this equipment, and that the company holds the right classification where your building sits. Ask for both.

Our door dropped. Can we just roll it back up?

No — and this is the mistake that turns a small problem into a big one. A rated door drops because something released it. Rolling it back up without finding out why leaves you with an assembly that may not work when it matters, and it can damage the door. Report it and let a qualified provider reset it properly.

Can our regular maintenance vendor do the annual fire door test?

Only if they hold the right classification and the technician is trained for rolling steel fire door systems. This is worth asking specifically, because a general door maintenance agreement does not automatically include rated-assembly testing. If your maintenance proposal quotes "per bay," ask whether the rated doors are itemized separately — they usually should be.
