What is the required clearance from soil to joist in a pest inspection?

The required clearance from soil to joist in a pest inspection is 18 inches. This measurement is important because it helps prevent moisture-related issues and provides adequate space for pest inspections and treatments. A clearance of at least 18 inches allows for proper air circulation, which reduces the risk of wood decay and creates an environment that is less conducive to pest infestations.

In addition to these structural benefits, maintaining this clearance also complies with building codes and pest management guidelines, ensuring that all pests, including termites and rodents, can be effectively monitored and managed. This clearance is a standard practice in structural pest control to enhance the durability of the building's foundation and prevent conditions that attract pests.
