What is the minimum distance from exposed ground for a wood framing member that is in contact with?

The minimum distance from exposed ground for a wood framing member that is in contact with it is typically set at 18 inches. This requirement is in place to protect the wood from moisture that can lead to rot and deterioration. Building codes specify this distance to ensure that any wood framing components, such as sill plates or joists, do not come into direct contact with the soil, which can retain moisture.

Wood that is in contact with the ground is particularly susceptible to damage from water and insects, making the specified clearance an essential part of building practices. The distance also allows for ventilation and helps to keep the framing member dry, which is crucial for maintaining structural integrity and longevity.

In essence, maintaining an 18-inch clearance is a critical aspect of building construction, particularly in areas that may be exposed to varying moisture levels. Understanding this requirement ensures that builders and contractors adhere to safety and durability standards in their projects.
