The 2024 International Residential Code (IRC), published by the International Code Council, provides comprehensive regulations for the construction of one- and two-family dwellings as well as townhouses up to three stories in height. The code integrates requirements for building, plumbing, mechanical, fuel gas, and electrical systems into a single coordinated document. By consolidating these essential provisions, the 2024 IRC serves as a reliable and authoritative standard for safe, efficient, and code-compliant residential construction.
