Attaching a ledger board

spacer provides relief from building movement and deck movement cracking the stucco. The masonite also gave us a way to nail on our plastic, securing the plastic with masonite blocks.

An existing stucco house would require cutting and patching the stucco.
Cutting a gap in the stucco for the flashing, and patching the lath and stucco
to overlap the flashing.
