    Question Anchoring deck to cement foundation

    Is there a way of attaching a ledger board for a deck directly to foundation wall without jeopardizing the integrity of the foundation. Deck size is 10'x 28'

    You'll have to check with your local building inspector office at town hall---there has been a rash of deck collapses in recent years & each town has their own specs on how to do this.

    Lead anchors and lag bolts are not allowed anymore in many areas.

    Frost/thaw cycles have caused failures of a number of ledger attachment methods, so town specs have become very specific as to what method you can use.

    What's wrong with sinking concrete anchored posts right next to the foundation?

    Or using both a ledger and anchored posts where the posts would reduce the sheer load on the ledger and the ledger would prevent the posts from shifting away from the foundation?
