You need the 2021 IRC for One- and Two-Family Dwellings — NOT the 2012. The full 2021 IRC PDF (1,109 pages) is in your project folder at source_material/irc_excerpts/IRC_2021_FULL.pdf. Print and spiral-bind, OR buy the physical 2021 IRC from ICC or Amazon. Per PSI rules: highlights/underlines/permanent tabs OK, NO writing, NO loose papers, NO Post-It flags.
Pre-tab the 2021 IRC by chapter map: Concrete=Ch4, Masonry=R606/R703.8/R1003, Carpentry=Ch5/Ch6/Ch8, Roofing=Ch9 (R905), Insulation=Ch11/N1102.1.3, Egress=R310, Glazing=R308, Stairs/Guards=R311.7/R312, Fire-rated walls=R302.6, Smoke=R314, CO=R315.
Authority hierarchy on the test: VA USBC > 2021 IRC > industry standards. Where state code (USBC) and IRC conflict, USBC wins.
