What is the minimum required width of a concrete footing for a one-story dwelling on a slab foundation?

10 inches
12 inches
14 inches
16 inches

The correct answer is: 12 inches

For a one-story dwelling on a slab foundation, the minimum required width of a concrete footing is typically set at 12 inches. This requirement helps ensure that the footing can adequately support the loads imposed by the structure, distributing them effectively to the ground beneath. The width is critical for maintaining stability and preventing issues such as settling or cracking that could arise from inadequate support. Standards and building codes often establish these minimum widths based on factors like soil bearing capacity, the weight of the structure, and local environmental conditions. A footing that is 12 inches wide provides a balance between sufficient support and cost-effectiveness in the construction process. Ensuring adherence to these standards is crucial for the integrity and longevity of the building.
