I inspected the deck at our rented home and found the following:
The ledger board is attached directly to the brick veneer.
Some of the boards were showing splintering, rotting, and nail head protrusion.
The posts did not appear to be resting on footers, but am unable to make a clear determination of this. One of the posts was clearly not attached, but was sitting directly on top of a brick retainer wall, at the corner of the deck.
The deck would benefit from additional lag bolts.
Recommend a qualified contractor replace the rotting boards, and anchor the corner post.
