A fire door inspector inspects and tests fire door assemblies — the doors and their closing, latching and hold-open hardware that protect openings in walls, floors and ceilings against fire and smoke — against NFPA 80, and documents what passes and what fails.
The work runs on an annual cycle: recurring fire door inspection entered NFPA 80 with its 2007 edition (per Intertek's program notes), hospitals answer for it through CMS surveys, and the trade trains through DHI and Intertek.
What is a fire door inspector?
A fire door inspector is the specialist who verifies fire door assemblies against NFPA 80 and documents the result.
The scope of the job comes straight from the standard itself: NFPA 80, Standard for Fire Doors and Other Opening Protectives.
That standard regulates the installation and maintenance of assemblies and devices used to protect openings in walls, floors and ceilings against the spread of fire and smoke.
That scope — doors and the hardware that closes, latches and holds them — is the inspector's daily material.
As of October 2026, NFPA lists 2025 as the current edition.
The work itself is verification and documentation.
The inspector moves through a building assembly by assembly, operates each door, checks its components, and records the condition of each assembly in the written record.
Deficiencies get written up and routed to the people responsible for the assemblies.
The inspector's product is the record, not the repair.
CMS's hospital survey tag, for one, checks that written fire door inspection records are available for review.
The inspector documents conditions for the people responsible for the assemblies.
That makes fire door inspection a different job from that of the fire inspector, whom BLS describes as ensuring compliance with state and local fire codes, and different again from installers and ITM inspectors.
Who the work suits is easy to describe — people who like buildings, hardware, and paperwork that has to be right.
What NFPA 80 requires each year
The yearly rhythm of this career comes from NFPA 80's inspection requirements.
Intertek, which runs fire door inspector training alongside DHI, notes that the 2007 edition of NFPA 80 introduced requirements for the ongoing annual safety inspection of fire door assemblies.
NFPA lists the 2025 edition as current.
Hospitals answer for that requirement through CMS.
Survey tag K761 on Form CMS-2786R requires fire door assemblies to be inspected and tested annually in accordance with NFPA 80, by individuals who understand the operating components of the door, with written records available for review.
The tag cites NFPA 80's inspection sections 5.2 and 5.2.3, and the edition it references under the 2012 Life Safety Code is NFPA 80-2010.
The tags carry that 2012 frame because the Medicare hospital Conditions of Participation, 42 CFR 482.41, incorporate the 2012 edition of NFPA 101 — issued August 11, 2011, with TIAs 12-1 to 12-4 — so hospitals are surveyed against 2012 Life Safety Code requirements.
Federal buildings run on their own book.
The DoD's UFM 3-601-02 (2026) schedules annual tests of hinged and sliding fire doors — hold-open release, closer operation, and closing and latching — and puts fire and smoke damper tests one year after construction and every six years thereafter.
That schedule — one year after construction, then every six — is the DoD's own rule, not NFPA's; don't confuse it with NFPA's damper cycle, which the last section covers.
It is a useful reminder that facility owners can layer their own criteria on top of the standards, and an inspector who works federal buildings learns to tell the two apart.
Which edition governs a given door?
Where fire door inspectors work
The demand side of this job is recurring inspection obligations, and the clearest ones in the public record are institutional.
Hospitals inspect fire door assemblies every year under CMS tag K761, with written records, and federal facilities follow the DoD's annual door tests and its one-year-then-six-year damper schedule.
Those two obligations put door inspection on the calendar across Medicare-participating hospitals and the DoD's facilities.
Where the inspectors themselves sit is harder to pin down: our research did not establish a typical employer mix for fire door inspectors, and this page will not guess one.
What the trade's structure shows is the shape of the work rather than a headcount.
Inspection is per-assembly route work through occupied buildings, the written record is the deliverable, and the training and credentialing for the role come from the door and hardware industry's own institutes, covered in the next section.
For anyone mapping a career here, the adjacent jobs are worth naming.
The fire inspector who checks compliance with state and local fire codes is a separate career with its own hiring path, and certification requirements that vary by state and locality.
The wider inspection world of sprinkler ITM, extinguisher service and alarm testing shares the same route rhythm, and door work pairs naturally with damper and firestop inspection, which the last section covers.
Together those pieces make fire door inspection a specialty that fits alongside other inspection work as easily as it stands alone.
Certifications employers look for
The credential path for this trade runs through DHI and Intertek.
DHI — the Door and Hardware Institute — teaches the Fire and Egress Door Assembly Inspection class, DAI 600, and students who complete it may enroll in Intertek's Certified Fire Door Inspector program.
DHI's own certification is the Certified Fire & Egress Door Assembly Inspector, CFDAI: complete the DAI600 course and pass its exam.
DHI frames the CFDAI around performing and documenting inspections and communicating with owners and AHJs.
Inspectors who hold the FDAI designation but elect not to join the certification program can still use the FDAI credential.
On the requirements side, be precise about what anyone actually mandates.
The CMS hospital tag points to individuals who understand the operating components of the door rather than to a named certificate.
Our research did not establish that NFPA 80 itself requires a certification, either.
Treat the CFDAI and the earlier FDAI designation as the trade's own training and credentialing structure — the one the door and hardware industry's institutes publish.
And treat any specific certification demand as an employer or AHJ question to ask directly before you enroll or quote work.

Pay and career path
Pay is the honest gap on this page: our research did not establish a published wage figure for fire door inspectors, so there is no number here, and a made-up range would be worse than an admitted one.
The role has no dedicated government wage series we could verify.
Ask hiring employers what route work pays in your market.
Our research did not establish course or exam costs either, so confirm those with DHI and Intertek before weighing an offer.
What we can describe is the shape of the path.
Fire door inspection rewards component-level knowledge: the CMS tag points to individuals who understand the operating components of the door, and the DoD's door tests name the items a working inspector reads at a glance — hold-open release, closer operation, closing and latching.
Nothing in the public record we read mandates a specific background.
The places a candidate would build that component knowledge — door and hardware work, fire protection inspection service, facility engineering in the buildings where these assemblies live — are the natural ones to ask employers about.
Once in, inspectors widen what a route can cover by adding fire and smoke dampers and firestop inspection — adjacent work with its own published schedules and practices, detailed in the next section.
On the credential side, DHI's CFDAI is earned by completing the DAI600 course and passing its exam.
Related work: dampers and firestop
Fire and smoke dampers are the natural second system for a fire door inspector, and the schedules are public.
NFPA 80's Chapter 19 requires fire dampers to be inspected and tested one year after the initial acceptance test and then every four years — unless the dampers are installed in a hospital, where a six-year cycle applies.
NFPA 105 sets the same schedule for smoke dampers.
NFPA's published ITM guidance also calls for damper inspections and tests to be documented, with records kept for at least three test cycles.
The code side points the same direction.
The International Fire Code's 2024 edition assigns fire damper inspection, testing and maintenance to NFPA 80, and smoke damper ITM to NFPA 105, in its Table 901.6.1.
An inspector who knows where those assignments land can read a damper work order and know which standard governs before the ladder goes up.
Firestop is the adjacent specialty with its own book.
ASTM E2174 is the standard practice for on-site inspection of installed firestop systems, giving procedures for qualified inspectors to verify that firestops were installed per the inspection documents.
Its companion, ASTM E2393, covers on-site inspection of installed fire resistive joint systems and perimeter joint protection.
