What is the minimum width of a footing for light frame construction?

• A. 8 inches
• B. 10 inches
• C. 12 inches
• D. 14 inches

Answer: (C)

The minimum width of a footing for light frame construction is generally considered to be 12 inches. This dimension helps to provide sufficient bearing capacity and stability for the load of the structure while ensuring compliance with building codes. A footing that is too narrow may not distribute the weight of the building effectively onto the soil, which could lead to settling or shifting over time. In light frame construction, which typically involves materials like wood, ensuring that the foundation is adequately designed is crucial for the integrity and longevity of the building. The choice of 12 inches as a minimum width also balances practical considerations such as ease of construction and material usage. Wider footings may be necessary in certain conditions, such as on weaker soils, but 12 inches is a standard baseline for many applications in residential construction. Other options suggest narrower widths, which may not provide adequate support as required in typical structural practices.
