I would like to build a small, 24" high deck, for a new entry door to the house. I have the deck plans all laid out, and am in need of a 2x10 ledger board under the door to attach the deck to. Most of what I have read on attaching a ledger board, suggests using large carriage-bolts through the ledger board and rim joist, with a nut/washer on the back side. Unfortunately, this section of the house has a finished basement, and it would be quite difficult if not impossible to access the back side of the rim joist.
What other options do I have? Would some hefty lag-screws work?
