Wood siding installed on the exterior of a structure must have a clearance of how many inches from the ground?

The requirement for wood siding to have a clearance of 6 inches from the ground is based on building codes that aim to protect the material from moisture-related damage. Wood is susceptible to rot and deterioration if it is in direct contact with the ground or exposed to accumulating water. By establishing a clearance of 6 inches, the design minimizes the potential for wood to absorb moisture from the soil, especially during rainfall or flooding, which can lead to long-term structural issues.

In many building codes, this clearance standard is meant to ensure that adequate ventilation exists beneath the siding, allowing for faster drying times and reducing the likelihood of mold and pest infestations. This precaution is essential for maintaining the integrity and longevity of wood siding, making it a best practice in residential construction.
