What is the minimum clearance required between wood siding and the earth exterior of a building?

The minimum clearance required between wood siding and the earth exterior of a building is 6 inches. This clearance is mandated to prevent moisture accumulation that can lead to wood rot and pest infestation, which can compromise the structural integrity of the building. Maintaining this distance ensures that any potential water from the ground can drain away without coming into contact with the siding. Additionally, this separation helps promote ventilation and reduce the risk of mold growth. Proper clearance is a critical aspect of building codes and best practices in construction to enhance the longevity and durability of wooden materials in a building’s exterior.
