ICC Fire Inspector II (67) Exam Topics: How the Weights Shift from 66
Exam 67 tests the same four domains as Fire Inspector I against the same two books — but occupancies and hazardous materials each gain five points. The published weights, compared.

ICC Fire Inspector II (67) Exam Topics: How the Weights Shift from 66
ICC publishes the domain weighting for exam 67, and the useful way to read it is against exam 66 — because the domains and the reference books are identical, and only the distribution changes.
| Domain | 66 | 67 |
|---|---|---|
| General Provisions for Fire Safety | 48% | 36% |
| Occupancies | 17% | 22% |
| Regulated Materials and Processes | 17% | 22% |
| General Inspection Administration | 18% | 20% |
50 questions, two hours, open book. That is 2.4 minutes per question — slightly more breathing room than 66's two minutes, on a shorter paper.
What the shift actually means
Fire Inspector I is a lopsided exam: one domain is nearly half of it, and if you are strong on means of egress you can carry a lot of weak areas.
Fire Inspector II is flat by comparison. The largest domain drops to just over a third, and the two smallest each gain five points. Occupancies and Regulated Materials together are 44% of exam 67, against 34% of exam 66.
Practically: the areas you could afford to be thin on for 66 are the areas that decide 67. Candidates who took 66 recently and assume the same preparation transfers tend to find that out in the exam room.
Occupancies — 22%
About eleven questions, up from ten on a longer paper — a real increase in proportion.
Almost all of this is IBC Chapter 3 plus occupant load in §1004. Classification and occupant load calculation, and the exam gets at it through thresholds and edge cases rather than straight definitions:
- An assembly space under 50 occupants is Group B, not Group A.
- Group A-2 has no occupant-load threshold — it is defined by the use (food and drink consumption), not the count.
- A home day care for five or fewer children is part of the building's primary occupancy, not a Group E.
- A communication equipment structure under 1,500 sq ft is Group U.
- Mixed-use floors: each function's area is calculated independently, not blended and not taken at the most restrictive factor.
These are learnable quickly and worth disproportionate marks. This is the highest-return study area on exam 67.
Regulated Materials and Processes — 22%
About eleven questions, IFC-side: hazardous materials storage and handling, permit thresholds, required emergency planning, and interior finish classifications.
It is open book, so do not memorise the hazardous-materials tables. Learn the structure of IFC Chapter 27 well enough to land on the right table in seconds, and memorise only the handful of general requirements that get asked directly — the emergency plan requirement, the general permit triggers, the flame-spread classes.
General Provisions for Fire Safety — 36%
Eighteen questions, and still the largest single domain even after the drop.
Means of egress, construction types, system readiness, emergency access. Spread across IBC Chapter 10 and IFC Chapter 10, which are not identical, plus IBC Chapter 6 and IFC Chapter 9.
The exception pattern from exam 66 persists here. If a question specifies a number, that number is usually placing the scenario on one side of a threshold — and the base rule is the trap. Stepped aisle widths, ramp landing lengths, riser heights in particular occupancies.
General Inspection Administration — 20%
Ten questions, up two points from 66. IFC Chapter 1: permits, recordkeeping, appeals, legal proceedings, scope and applicability, and the authority of the fire code official.
ICC's published outline for 67 lists scheduling as a task here, which exam 66's outline does not break out separately. That is consistent with the seniority difference — Fire Inspector II is closer to running an inspection programme than to executing individual inspections.
If you came to this from contracting rather than from a jurisdiction, this domain remains the least intuitive on the paper and deserves a dedicated pass rather than a skim.
A study plan for someone who has just passed 66
Do not restudy in the same order. The marginal value is concentrated:
- Occupancies, properly. Chapter 3 and §1004 until the thresholds are automatic. Highest return per hour on this exam.
- IFC Chapter 27 structure. Not the tables — where the tables are.
- IFC Chapter 1 again, deeper. It went up, and it is the domain people never quite finish.
- Refresh egress and construction, but do not re-learn it. It is still the biggest domain, but it is the one you are already strongest on.
- Practise at 2.4 minutes per question. Slightly more time than 66, on questions that lean a little more toward classification and a little less toward multi-step egress calculation.
Take it while the books are still tabbed
The strongest practical argument for sitting 67 soon after 66: same two books, same tabs, same navigation skill. That skill is perishable, and it is a significant part of what open-book exams actually test.
