Just curious. I could not tell from the photos, but are you directly burying the PT posts for the deck? Around where I live, the code requires that the posts be supported on a concrete footer, and they have to be placed on a standoff bracket, usually galvanized, to reduce rot potential. I suppose if you used direct burial rated PT my BI might allow direct burial, never did check.
Also, in my town, the beams are required to be installed on a notched post, they can't be bolted directly onto the post. This means that the minimum post size is 6x6, not 4x4, which of course adds somewhat to the cost. I couldn't tell if your posts were notched, but they do look like 4x4.
Differences in local code interpretation I guess. The deck looks very nice, I llike the cedar.
