Description
2024 International Residential Code for One- and Two-Family Dwellings (IRC)
The 2024 International Residential Code, published by the International Code Council, is a freestanding set of regulations for homebuilders, structural engineers, contractors, architects and code officials. It applies to the design and construction of one- and two-family dwellings and townhouses up to three stories in height.
The code brings building, plumbing, mechanical, fuel gas, energy and electrical provisions into one volume, so a residential project can be checked against a single reference instead of several code books.
What the code covers
Structural, electrical, mechanical and plumbing requirements sit alongside each other in the same volume, along with fuel gas and energy provisions, so the disciplines involved in building a house are covered without cross-referencing separate ICC codes.
Compliance pathways
The code sets detailed prescriptive requirements and also allows performance-based design, giving a project team room to work outside the prescriptive tables on more complex designs.
