What is the minimum clearance required between wood and soil in a building?

The minimum clearance required between wood and soil in a building is 6 inches. This specification is crucial for preventing moisture accumulation and potential pest infestations, such as termites. Having wood components of a structure, like framing or siding, in direct contact with soil can lead to deterioration and provide a conducive environment for pests, particularly in areas where humidity is high.

Maintaining a clearance of at least 6 inches creates a barrier that helps in airflow and reduces the likelihood of wood decay caused by moisture. It also minimizes the chances of termites gaining access to the wood, as they are often found in the soil. Building codes and standards emphasize this clearance to enhance the longevity and safety of structures.
