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

The minimum footing width for a one-story light-frame construction building is typically set at 12 inches. This sizing ensures that the footing can adequately support the weight of the structure distributed from the above loads, while maintaining stability and minimizing settlement.

In light-frame construction, which often involves wood framing and lighter materials, the structural configuration requires footings to be wide enough to provide a stable base without risk of failure under load conditions. A 12-inch width is a practical dimension that balances structural integrity with material efficiency, helping to comply with typical building codes and addressing the load-bearing capacity necessary for safety.

Understanding that the foundation system is critical for the overall longevity and performance of the building makes this footing width essential. Wider footings may be required in specific cases depending on soil type and load demands, but for general one-story light-frame structures, a minimum of 12 inches meets the standard requirements.
