R403.3.1.2

Section R403.3.1.2 is titled 'Attachment to heated structure' and covers requirements for footing construction. Cross-references to a figure and table in this code which construction must conform to, and clarification that insulation is not required between a frost-protected shallow foundation and an adjacent heated structure maintained at a minimum mean monthly temperature is established. The purpose of this section is to prevent structural failure.

The model shows the foundation of a heated structure adjoining a frost-protected shallow foundation.
