IRC 2021 International Residential Code – ICC Softcover
The 2021 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 major requirements for residential construction together in one coordinated volume.
The code covers building planning, foundations, floors, wall construction, roof systems, fire safety, energy conservation, mechanical equipment, fuel-gas systems, plumbing, and electrical installations. Its scope generally includes detached one- and two-family dwellings and townhouses that do not exceed three stories above the grade plane.
Its practical arrangement follows the usual progression of residential construction, beginning with planning and structural work before moving into finishes and building systems. This makes it useful during design development, permit preparation, plan review, construction, inspection, classroom instruction, and exam study.
The 2021 edition includes revisions affecting wall bracing, separation between two-family dwellings, emergency escape routes, storm shelters, habitable attics, wind-design information, deck construction, ventilation, plumbing-system testing, dwelling sprinklers, electrical service disconnects, surge protection, and GFCI requirements. Its residential electrical provisions are based on the 2020 National Electrical Code.
This book is suitable for residential builders, contractors, architects, engineers, building inspectors, plans examiners, code officials, trade instructors, apprentices, and construction students. Having building and system requirements in one book reduces the need to consult several separate codes for many common residential projects.
Code adoption and amendments differ by location. Buyers should confirm that the 2021 edition is required for their jurisdiction, project, course, employer, or examination.
