Incorrectly attached metal deck joist hangers

Metal deck joist hangers should NOT be fastened directly to exterior siding, as pictured here.  It’s important to fasten deck joist hangers to a bolted ledger for safety reasons.  Amazingly, this is discovered quite frequently.   The easiest “fix” for this is to install a bolted ledger directly underneath the deck joists.  This photograph was taken at a recent home inspection in Bellingham.
