What is the minimum footing width of a one-story light-frame-construction building?

• A. 8 inches
• B. 12 inches
• C. 16 inches
• D. 20 inches

Answer: (B)

The minimum footing width for a one-story light-frame construction building is typically set at 12 inches for several important reasons related to structural integrity and load distribution. A footing's primary purpose is to distribute the weight of the building over a larger area of soil to prevent excessive settlement or movement. A width of 12 inches is generally adequate for most one-story light-frame structures to support the load without exceeding the bearing capacity of the soil beneath. It also allows for adequate lateral stability and ensures that the footing can handle potential uneven settling as soils may change over time due to moisture fluctuations or loading conditions. Additionally, building codes and construction guidelines are designed to accommodate standard practices while being versatile enough to handle small variations in site conditions. The choice of a 12-inch width considers these factors, ensuring that the building remains stable while also allowing for ease of construction and effective utilization of materials. Choosing a width smaller than 12 inches could risk inadequate support for the building, which could lead to structural issues, while a width larger than 12 inches may not be necessary for a single-story structure, potentially resulting in wasted resources and increased costs.
