Can you attach a beam to a ledger board?

From a more general engineering standpoint, the main concern with attaching a beam or girder to a ledger or a rim joist is the potential for lateral torsional buckling. This is where a long, slender beam with little to no lateral support twists under load, sometimes under its own weight.

Do freestanding decks need footings?

According to the main code provision for footings, the only requirement for building a deck that is freestanding is that it must have a minimum footing depth of 12 inches below the undisturbed ground surface. There is no need to extend a footing below the frost line, as is required for standard decks.
