Steps
Open the 2024 IRC Chapter 10 free viewer and note the sections flagged as updated: R1001.11 (fireplace clearance), R1003.18 (chimney clearances), R1004.4 (unvented gas log heaters), R1005.9 (factory-built chimney offsets), R1006.2 (exterior air intake)
Compare each against the corresponding 2021 IRC text (also free-viewable) to identify the specific numeric or scope change
Confirm which edition the relevant state/local jurisdiction has actually adopted before assuming 2024 language applies, since most jurisdictions lag the ICC's 3-year publication cycle
Flag any change relevant to inspection/certification work — e.g., factory-built chimney offset limits affect what a Level 2 inspector should check
Known gotchas
ICC's free viewer shows the model-code text; state-specific amendment versions (e.g., the California or New York residential code viewers on the same site) can override individual sections
"2024 IRC" and a state's "2024 [State] Residential Code" are not guaranteed identical — pull the state-specific viewer link, not the base ICC model code, for jurisdiction-specific work
