In this episode of Build Better Homes, Royal Mortier and John O’Shea break down 2024 International Residential Code (IRC) updates that are actively impacting projects in 2026.
While the code cycle is labeled 2024, many jurisdictions are adopting and enforcing these changes now, making their real-world implications more relevant than ever. Royal and John focus on the updates that actually affect builders, designers, and homeowners today, not theoretical changes buried in the book.
The conversation covers how extreme cold events are exposing weaknesses in regions not historically designed for freezing conditions, how frost depth and soil assumptions are being challenged, and which code updates offer real flexibility versus added complexity.
A key highlight is the expanded allowance for using USDA soil classifications as an alternative path to higher allowable bearing pressures, a change that can reduce concrete volumes, shorten schedules, and avoid unnecessary geotechnical reports when applied correctly.
These may be called the 2024 IRC updates, but their consequences are being felt now. Knowing how to apply them in 2026 is what separates compliance from competence.
