How many inches from the ground must the siding of a residential home be kept?

The correct answer is that the siding of a residential home must be kept a minimum of 6 inches above the ground. This standard is primarily implemented to prevent moisture-related issues and to protect the siding materials from deterioration. Keeping the siding at this height helps minimize the risk of water infiltration, which can lead to rot, mold growth, and pest infestations. Maintaining this clearance is especially crucial in areas prone to heavy rainfall or flooding, where water can accumulate near the foundation.

Other options, while they may represent reasonable heights, do not align with the regulations aimed at ensuring durability and longevity of the siding. Heights lower than 6 inches could expose the siding to moisture and debris from the ground, increasing maintenance issues and the potential for damage.
