The connection between a building’s frame and its foundation is critical to structural integrity. This junction, created through proper foundation anchorage, enables a building to resist lateral forces from earthquakes, high winds, and other environmental forces. This article translates the code requirements for foundation anchorage in [International Residential Code IRC® Section R403.1.6](https://codes.iccsafe.org/content/IRC2024P2/chapter-4-foundations#IRC2024P2_Pt03_Ch04_SecR403.1.6) into practical inspection guidance for home inspectors, code inspectors, and contractors.
