ICC B1 study plan

Trace the load path of a roof/ceiling assembly from ceiling joist through rafter to ridge, labeling each member and the point at which it must be inspected before concealment.

Build a personal lookup table for rafter and ceiling-joist span limits, notch and boring restrictions, and fastening schedules, then solve 10 framing scenarios using only that table.

Distinguish when a rafter tie, collar tie, ridge strap, or purlin is required, and write a two-sentence justification for each condition in your own words.

Rank the ten most common roof-framing inspection failures by frequency and pair each with the specific correction an inspector would write.

Classify roof-covering materials by minimum slope, underlayment requirement, and attachment method, recording the threshold values for each class in a comparison grid.

Sketch a chimney cross-section showing clearance to combustibles, height relative to the roof surface, flashing, and spark-arrestor details, annotating each dimension requirement.

Sequence the inspection steps for a masonry fireplace and flue from foundation through termination, noting what must be verified at each stage.

Solve 15 mixed roof-covering and chimney scenarios and cite the basis for every answer.

Determine footing width, thickness, and bearing depth for three given soil and load conditions, showing the table lookup and the arithmetic.

Diagram foundation drainage, dampproofing, and waterproofing requirements and mark where each applies on a below-grade wall.

Calculate allowable floor-joist spans, cantilever limits, and bearing lengths for four framing layouts, then check each against notch and hole restrictions.

Verify crawl-space access, ventilation, and clearance provisions for two sample floor assemblies and list any deficiency found.

Explain how floor framing connects to wall framing at bearing points, and identify the inspection hold points where that connection is verified.

Evaluate wall-framing details for stud spacing, header sizing, lateral bracing, and fireblocking across four sample wall sections.

Compare interior and exterior wall-covering requirements, including weather-resistive barrier, flashing integration, and clearance from grade for each exterior finish.

Convert eight field scenarios into pass or correction rulings, citing the requirement behind each ruling.

Assemble a wall-construction inspection checklist that covers framing, sheathing, flashing, and exterior finish termination in inspection order.

Outline the permit-to-certificate-of-occupancy workflow and identify where plan review, rough inspection, and final inspection sit within it.

Distinguish the inspector's authority from the designer's or contractor's responsibility, and describe when a correction notice, stop-work order, or approval is the correct action.

Resolve ten administrative scenarios involving altered plans, field changes, and re-inspection, recording the correct procedural response.

Compute required light and ventilation openings for four rooms of given size and occupancy, then state whether each design complies.

Evaluate emergency escape and rescue openings and egress paths for three floor plans, checking sill height, clear opening, and travel distance.

Check stairway, guard, and handrail geometry in two sample plans against width, headroom, riser, and tread requirements.

Summarize how planning provisions connect to the inspection process so that a plan-review comment and a field correction cite the same requirement.

Rank all seven domains by your measured accuracy to date and allocate study time in inverse order to that ranking.

Take two 50-question timed mixed sets under exam conditions, then categorize every miss by domain and by error type: lookup, misread, or knowledge gap.

Rewrite each missed item as a single-sentence rule you can recall without the code book, and re-test yourself on those rules 48 hours later.

Rehearse locating a requirement in the code book within 30 seconds for five randomly chosen topics.

Complete two full-length timed mock exams under exam conditions, simulating the actual question count and time limit.

Review only your error log and weak-area summary, correcting residual gaps rather than re-reading broadly.

Condense all domain notes into a single one-page recall sheet organized by inspection sequence.

Verify exam-day logistics and rehearse your lookup strategy for unfamiliar questions.
