Foundation (stem) walls which support bale walls shall extend to an elevation of not less than six inches above adjacent ground at all points. The minimum width of the footing shall be the width of the bale it supports, except that the bales may overhang the exterior edge of the foundation by not more than three inches to accommodate rigid perimeter insulation. Footings shall extend a minimum of 12 inches below natural, undisturbed soil or to frost line, whichever is lower.
