Interpretation #8644

There are 2 perspectives that could be considered in answering this question: 1. A carport is not a primary structure, however, the FBC-B 1816.1.6 and FBC-R318.1.6 both discuss soil treatment within 1 foot of the primary structure. The word "residential" does not exist in either code section. Therefore, soil treatment for the prevention of termites is required for the 12" dimension. 2. What can the termites infest/destroy? A concrete slab and associated metal carport typically provide no food for subterranean termites. Although the code does not make such a statement, preventative treatment for subterranean termites implies that there is something present in the structure that can provide food and be therefore destroyed by the termites. Keep in mind, Formosan Termites consume concrete and masonry.
