Existing Interpretations and/or Declaratory Statements Related to this request

Input Received:

Table R803.2.2 is specific to use of wood structural panel sheathing. See definition -wood elements that are bonded together with exterior adhesives (examples LSL, LVL, OSL, and PSL)

There is no conflict and no need for one to take precedence as Table 803.1 is for lumber and 803.2.2 is for structural panels so they each apply according to which product you wish to use
