Hello,
I am trying to build a 4 foot overhang on my horse lean to. I can’t attach to original rafter because they were placed on angled joist hangers. So I have a ledger board going across the 30 foot span of the structure. This ledger board is against 6×6 post that are 4 feet in the ground with concrete. The problem I am encountering is there are only 4 post (2) that are 12 feet apart making two stalls and one just 6 feet apart making a tack room. How can I frame a 4 foot overhang on this 30 foot span structure? I live in central Florida so wind uplift is the only concern.

My opinion is, at a glance it looks very underbuilt even now. Any significant wind event could take that sail away. I don't see how you could add 4' overhang to any side of that with out more posts and etc. But maybe I'm seeing this all wrong..
In regards to the post I have seen some where they put post at end of overhang. But I was told since it’s just a 4’ overhang it doesn’t need it but I’m thinking it does.
Well it’s work in progress. The 3 walls you see there in the back are already completely enclosed. The rafters are tied down. The left side will be completely enclosed because it will be a tack room. The right sides will be two stalls. But yes they will be opened. I have seen some around here that were build professionally with an overhang just like what you see here. So I fail to see the problem you are speaking about.
I know this will hurt but your barn looks like it could fall down tomorrow. What I see in the photo is 6 X 6 posts leaning way out of plumb, no beams supporting the roof and roof rafters that look like they are already sagging. At the top and bottom of your roof, you should have a doubled beam with lapped splices made of at least the next size up from your rafters. An overhang should have been done while the shed was under construction.
