Per our discussion with Taylor Morrison, it's our understanding that for some of the exterior decks, a 1/4"(+/-) spacer has been installed between the deck ledger& exterior sheathing for waterproofing purposes. Based on our review of the plans, this is an acceptable method of construction provided the minimum 2" penetration of the deck ledger fasteners to the rim/blocking is maintained per detail 18/S9.2 (Typical Deck Framing).
