What is the minimum width of the footing for a one-story house?

Explanation:
Distributing the building’s weight evenly to the soil is the main purpose of a footing. For a typical one-story house with standard soil and loads, a footing width of 12 inches provides enough bearing area to keep soil pressures within safe limits without being unnecessarily large. An 8-inch footing would be too narrow for most soils, risking overloading and settlement, while 16 or 24 inches would be excessive for a single-story structure. So the standard minimum width used in practice is 12 inches.
