1. Administration, Permits and Reports
The Administrative domain (24%): applying the right code, writing inspection reports, processing and enforcing permits, plan review applications, complaints and the code modification process.
Key facts
- A report entry states the condition, its exact location, the requirement violated and the corrective action with a deadline.
- Permits are issued, denied or revoked under the authority the fire code gives the AHJ; NFPA 1 lists the operations and activities that need permits.
- Equivalency: the AHJ may approve alternatives of equivalent or superior protection when technical documentation demonstrates it.
- Complaints are logged, investigated, documented and closed out with the complainant told the result where policy allows.
- Codes are adopted by law; local amendments and the edition adopted decide what applies in a jurisdiction.
- Inspection records are public documents in many jurisdictions, so write only facts you observed.
Flashcards
Exam tip: When two answers look right, pick the one that documents facts and follows AHJ policy. Inspectors don't improvise enforcement.
2. Legal Authority and Enforcement
The Legal domain (5%): legal proceedings, initiating legal action for code violations, right of entry and recommending inspection policies.
Key facts
- Camara v. Municipal Court and See v. City of Seattle (1967): non-emergency inspections without consent require an administrative warrant.
- Administrative warrants rest on a reasonable inspection program, not probable cause of a particular violation.
- Emergencies (an imminent danger to life) allow immediate action without a warrant.
- Enforcement usually escalates: notice of violation, reinspection, citation or summons, then court action.
- In court, testify from your reports, state facts not opinions outside your expertise, and answer only what is asked.
- Boards of appeals hear disputes over the AHJ's interpretation of the code.
Flashcards
Exam tip: Only 5% of the exam, but the warrant cases come up in nearly every inspector exam. Learn the names and the year.
3. Occupancy Classification and Occupant Load
Classifying occupancies and computing the maximum allowable occupant load under NFPA 101, a core Field Inspection and Plans Review task.
Key facts
- Assembly: 50 or more persons. Educational: 6 or more persons through grade 12, 4+ hours a day or more than 12 hours a week.
- Health care: 4 or more inpatients mostly incapable of self-preservation; ambulatory health care: 4 or more patients rendered incapable at the same time.
- Occupant load factors: assembly less concentrated 15 ft² net, concentrated 7 ft² net, standing 5 ft² net; business 150 ft² gross.
- Net area excludes walls, corridors, restrooms and fixed features; gross area is everything inside the exterior walls.
- Mixed occupancies are either separated (each meets its own chapter) or nonseparated (the most restrictive requirements apply).
- The posted occupant load in assembly spaces must not be exceeded.
Flashcards
Exam tip: Classify first, compute second. A wrong occupancy gives a wrong factor and every answer that follows is wrong too.

4. Means of Egress
Inspecting egress components: number, capacity, arrangement, doors, stairs, lighting and marking under NFPA 101.
Key facts
- Capacity factors: 0.3 in. per person for stairs, 0.2 in. per person for doors, corridors and ramps (most occupancies).
- At least 2 means of egress; 3 for more than 500 up to 1,000 occupants; 4 for more than 1,000.
Flashcards
Exam tip: Field egress items are what get people killed: locked or blocked exits and wedged-open stair doors. Expect those as the 'most serious violation' answer.
5. Building Construction and Interior Finish
Evaluating construction type, area and height, fire-resistance ratings, opening protectives and interior finish during inspections.
Key facts
- NFPA 220 construction types I to V; the three digits give hours for exterior bearing walls, columns/beams supporting more than one floor, and floors.
- Type I and II are noncombustible; Type III has noncombustible exterior walls; Type V is any permitted material, typically wood frame.
Flashcards
Exam tip: On the exam, 'noncombustible' and 'fire-resistive' are different ideas. Type II (000) is noncombustible but has no rating.
6. Fire Protection Systems
Evaluating sprinklers, standpipes, fire alarm and other systems, witnessing acceptance tests, and applying NFPA 25 inspection, testing and maintenance frequencies.
Key facts
- NFPA 25: sealed control valves inspected weekly; locked or electrically supervised valves monthly.
- Gauges on sprinkler systems are replaced or tested against a calibrated gauge every 5 years; internal pipe assessments every 5 years.
Flashcards
Exam tip: NFPA 25 frequency questions are lookups in the summary tables at the start of each chapter. Tab those tables.
7. Fire Hazards, Hazardous Materials and Site Access
Recognizing hazards in the field: flammable and combustible liquids, storage, housekeeping, building services, emergency planning, fire department access and fire flow.
Key facts
- Liquid classes: Class I (flammable) flash point below 100°F, Class II 100°F to below 140°F, Class IIIA 140°F to below 200°F, Class IIIB 200°F or more.
- Fire department access roads: at least 20 ft wide with 13 ft 6 in. vertical clearance; within 150 ft of all parts of the first-story exterior wall.
Flashcards
Exam tip: Hazard questions often ask for the 'most serious' finding. Ranking rule: blocked egress first, then impaired protection, then ignition hazards.
How to pass
- 72 questions in 3 hours is 2½ minutes each, which is generous. Use it to look up the exact table value rather than relying on memory.
- Field Inspection is 55%: occupancy classification, occupant load, egress, fire protection systems and hazards. That's where most of your tabs should go.
- Know which book answers which question: occupancy and egress are in NFPA 101, sprinkler installation in NFPA 13, inspection frequencies in NFPA 25, alarm rules in NFPA 72, and permits, access and hazards in NFPA 1.
- The CFI-I closed to new applicants after 30 June 2026. Check with your employer or AHJ which credential they require before you apply.
