What is the minimum depth below the frost line that footings need to be?
12 inches
Depth, Width, and Thickness of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.

What’s the frost line penetration map in the US?
Frost Line Penetration Map In The U.S. The frost line is simply the deepest point in the ground to which ground water will freeze. It’s also referred to as the frost depth. When water changes from liquid to solid, it expands 9% in volume. This resulted frost heave can be detrimental to footings and foundations.
