I am adding a shed lean-to to my garage. It will be built on a slab which has
been poured and ready for framing
But I have a problem with the slab. It is10′ by 24 ‘ feet with
one long side abutting the garage foundation.
The other long side is where the problem lies.
It is not 10 feet wide over the entire length!!!
At about 16 feet the width begins to narrow slowly down to about 9′ 11″.
My question is how do I lay the sole plate to take into account this situation?
I could lay the sole plate (and the wall) to follow the slab but that would make
setting up the roof rafters in a fashion that they were all slightly different! I really
don’t want to do this way.
What other options do I have?
Thanks

One friggin' inch you can fudge -- no one will notice.
If it were me, I would let the sole plate run long and hang over the inch. If you are concerned about enough bearing surface, switch to 2x6 out side walls. It won't add substantially to cost. If you are worried about the bottom of the sole plate being exposed for that inch, bend a piece of flashing first and put it under the sole plate and run it up an inch on the outside of the plate so now you have flashing on the bottom and one inch up th outside, then the sole plate, then put your plywood/siding over the flashing. You just would have to be aware of what you use for flashing and nails to limit galvanic reation. You could just wrap the entire sole plate in ice and water shield since it shouldn't be exposed to UV once you get plywood and siding on the wall.
