2021 International Residential Code

The International Residential Code (IRC) establishes minimum requirements for one- and two-family dwellings and townhouses using prescriptive provisions. It's founded on broad-based principles that make possible the use of new materials and new building designs. This 2021 edition is fully compatible with all of the International Codes (I-Codes) published by the International Code Council (ICC), including the International Building Code, International Energy Conservation Code, International Existing Building Code, International Fire Code, International Fuel Gas Code, International Green Construction Code, International Mechanical Code, International Plumbing Code, International Private Sewage Disposal Code, International Property Maintenance Code, International Swimming Pool and Spa Code, International Wildland-Urban Interface Code, International Zoning Code, and International Code Council Performance Code.
