Paraphrased from the certification content outline published by the International Code Council for the B1 exam. This page cites no code sections and reproduces no code text: your code book carries the requirements, and the skill this site trains is finding them fast.

How to drill it

  • Find the chapter of the International Residential Code that carries this subject and read it once for structure, not retention: what lives here, what gets sent elsewhere, which tables exist.
  • Write your own plain-language phrases for what this subtopic covers, then note the code's terms beside them. Mismatches between the two columns are exactly where exam questions cost you time.
  • Run timed lookups: pick a requirement named in the descriptor above, start a stopwatch, find the governing text in your book, stop. Log the seconds. Past two minutes is a miss even when the answer is right.
  • Weight your reps to the number above. Roughly 1 to 2 questions means this subtopic needs a handful of confident reps, not a week.
