IRC 2024 (International Residential Code)
The 2024 International Residential Code is a comprehensive reference for the design, construction, alteration, and inspection of one- and two-family dwellings and qualifying townhouses. Published by the International Code Council, it brings the principal requirements for low-rise residential construction together in one coordinated volume.
The IRC covers building planning, foundations, floors, wall construction, roof assemblies, fire safety, insulation, energy efficiency, heating and cooling equipment, exhaust systems, ductwork, fuel-gas installations, plumbing, drainage, water supply, and residential electrical systems. Its scope generally includes detached one- and two-family dwellings and townhouses not exceeding three stories above grade plane.
The 2024 edition includes notable changes involving fire-separation calculations for multiple dwellings on one lot, shared accessory rooms in two-family dwellings, energy-storage systems, battery protection in garages, sleeping lofts, updated snow, wind, and seismic maps, A2L refrigerants, CPVC joints, electrical load calculations for electric vehicles, and certain residential receptacle and circuit requirements.
A revised single-column design, modernized fonts, clearer table presentation, grouped figures, and QR codes for identifying technical changes make the book easier to navigate during plan review, inspection, study, and jobsite reference.
This edition is valuable for residential builders, general contractors, architects, engineers, building inspectors, plans examiners, code officials, trade instructors, apprentices, and construction students. It can support design development, permit preparation, construction planning, inspections, professional training, and examination study where the 2024 IRC is specified.
Code adoption and local amendments vary. Buyers should confirm that this edition applies to their jurisdiction, project, employer, course, or examination.
