ICC 21 study plan

ICC 21 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Code Administration and Scope of the International Codes

  • Map the ICC code family (IBC, IFC, IPC, IMC, IECC, IEBC) into a one-page matrix showing which code governs which project type

  • Trace Chapter 1 administration from permit application through certificate of occupancy in a 12-step written flow

  • Distinguish the authority of the code official, registered design professional, and contractor across 15 short scenarios

  • Answer 30 practice items on scope, referenced standards, and work in existing buildings, recording the section cited for every miss

Your checkpoint

One-page code-family matrix plus a 12-step permit-to-occupancy flow and a 30-item log with every miss annotated to a code section

Week 2

Building Planning, Occupancy Classification and Construction Types

  • Classify 25 written building descriptions into occupancy groups, including mixed-occupancy cases

  • Assign construction type to each of those 25 buildings using allowable height and area tables

  • Calculate allowable area increases for frontage and sprinkler protection on 10 worked examples

  • Resolve 8 mixed-occupancy separation questions by applying the most-restrictive and accessory-use rules

Your checkpoint

A 25-building classification worksheet with occupancy group, construction type, allowable area, and a self-score of at least 90%

Week 3

Fire and Smoke Protection Features

  • Build a rating table linking required fire-resistance to occupancy group and construction type for walls, floors, and roofs

  • Contrast fire walls, fire barriers, fire partitions, and smoke barriers by listing the standard each is tested to and its continuity rules

  • Specify opening protectives and penetration firestopping for 12 given wall and floor assemblies

  • Answer 40 practice items on shaft enclosures, exit enclosures, and dampers, then re-test every miss

Your checkpoint

An annotated fire-resistance rating table plus a 40-item quiz record showing a re-test score of at least 85% on missed items

Week 4

Means of Egress and Accessibility

  • Compute occupant load, egress width, and required number of exits for 10 spaces without reference notes

  • Check travel distance, common path of egress travel, and dead-end limits in 8 floor plan narratives

  • Apply accessible-route, clear-floor-space, and reach-range criteria to 12 written interior scenarios

  • Complete a timed 60-item means-of-egress and accessibility set, then rewrite each missed item as a rule statement

Your checkpoint

A timed 60-item egress and accessibility set scored at 80% or higher, with a one-line rule rewrite for every error

Week 5

Structural Design, Materials and Foundations

  • Trace gravity and lateral load paths from roof to foundation on two building sketches described in text

  • Distinguish prescriptive versus engineered design requirements for wood, steel, concrete, and masonry in a comparison table

  • Match soil, excavation, and footing requirements to 12 foundation scenarios

  • Answer 30 practice items on loads, seismic and wind detailing, and material standards, citing the governing chapter for each

Your checkpoint

Two written load-path diagrams plus a material-system comparison table and a 30-item practice log

Week 6

Building Envelope, Energy Efficiency, Mechanical and Plumbing Provisions

  • Assemble an envelope compliance checklist covering weather protection, thermal envelope, and moisture control

  • Apply energy-code requirements to 8 building descriptions, identifying the compliance path used

  • Compare mechanical ventilation, exhaust, and plumbing fixture-count requirements across 10 occupancy scenarios

  • Answer 30 practice items spanning envelope, energy, mechanical, and plumbing provisions

Your checkpoint

An envelope and energy compliance checklist applied to 8 building descriptions, plus a 30-item practice log

Week 7

Code Administration and Scope of the International Codes & Building Planning, Occupancy Classification and Construction Types & Fire and Smoke Protection Features

  • Work 40 cross-domain scenarios that require classifying occupancy, then setting height, area, and fire-resistance together

  • Re-drill the 25 highest-error items from weeks 1 through 6 until each is answered correctly twice

  • Recite from memory the administrative triggers that change a design decision: change of occupancy, addition, and alteration

  • Audit personal notes for gaps against the printed domain outline and close at least 10 gaps

Your checkpoint

A closed error log showing all 25 previously missed items answered correctly twice, plus a 40-item mixed set scored at 80% or higher

Week 8

Fire and Smoke Protection Features & Means of Egress and Accessibility & Structural Design, Materials and Foundations & Building Envelope, Energy Efficiency, Mechanical and Plumbing Provisions

  • Sit two full-length timed practice exams under exam conditions with no notes

  • Categorize every miss by domain and root cause: misread, unknown rule, or calculation slip

  • Re-teach the three weakest subareas using only the code text and personal notes

  • Finalize a one-page rapid-reference sheet limited to numbers you repeatedly miss

Your checkpoint

Two completed timed mock exams with domain-by-domain score breakdowns and a final one-page rapid-reference sheet

Milestones

Week 2: Score 90% or better on the 25-building occupancy and construction-type worksheet without notes

Week 4: Complete a 60-item means-of-egress and accessibility set in the time limit at 80% or better

Week 6: All six domains have been covered at least once, with a written error log of at least 40 items

Week 8: Score 80% or higher on both timed full-length mock exams, with no domain below 70%
