2024 International Residential Code® (Loose Leaf)

The 2024 International Codes® (I-Codes®) have undergone substantial formatting changes as part of the digital transformation strategy of the International Code Council® (ICC®) to improve the user experience. The changes, promoting a cleaner, more modern look and enhancing readability and sustainability, include:
Single column text format and modernized font styles improves readability
QR Codes replace vertical margin sidebars and arrows to identify code changes more accurately
Shading for table headers and notes improves locating tables and applicable notes
Grouping of associated content brings tables and figures immediately after the parent section
 
This comprehensive code comprises all building, plumbing, mechanical, fuel gas, energy conservation and electrical requirements for one- and two-family dwellings and townhouses up to three stories. The 2024 IRC® contains many important changes:
