I’m adding to a garage and need to build stud walls against an existing concrete block wall. The stud walls will get stucco to match what’s on the the block wall.
How should I build the joint where the two types of wall meet? The best idea I’ve had yet is to stick expansion joint material between the walls, then end the sheathing an inch or two short on the stud wall to let the stucco to be a little bit thicker at the joint. This sounds pretty cheesy though. What’s the right way of doing it?

I think I would put a galvanized or zinc alloy plaster stop (#66) at the termination of the frame next to the block. Leave about a 1/4" space for backer rod and caulk. This will leave a nice straight deliberate looking joint rather than a crack.
*Thanks John. A stop will give it a cleaner edge and will be a lot simpler than the mess I had in mind.I was worried about having only 7/8" thickness of stucco with which to build the joint, but I get the feeling I was overthinking that part of the problem. I'm still worried about water getting through the joint and into the sheathing, but flashing the end of the stud wall should take care of that ...right?
