This is YOUR fence right? I’m just asking since usually the ‘clean’ side faces out, towards the neighboring property and is often set back a little from the property line. This saga would take quite the turn if it ends up it’s HIS fence and the paneling is hanging over the fence, but still on his side of the property line. It’s possible that since he is anchoring it to the deck, and I don’t see any braces on the house, that this may curtail some code requirements. Spoiler I’m obviously talking out of my ass and don’t have any real knowledge of how these codes are written. I do however love to observe some neighborly drama and watching the world burn.
