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
Users have capability to validate authenticity of their book and register it with the ICC to receive incentives.

The 2024 IPSDC® companion to the IPC® includes provisions for design, installation, and inspection of private sewage disposal systems, and provides flexibility in the development of safe systems.
