I inspected this deck yesterday. Yes, there are many things wrong wirh it. The entire beam span was not supported by or attached to the posts properly. I am writing up that a beam splice did not bear on a post.
My question is should all beam splices occur over a supporting post or does that change depending on the number of boards making up the beam? I know if an additional 4x4 support post had been used that the entire width of the beam would still not be supported.
