Mark and Jessica - Though stucco and gyp board are not officially removed from the Code as shear walls, I never use them as such. The performance is very poor. In my opinion, definitely go with the plywood for any designed shear wall. For that matter, I would be in favor of a "standard construction provision" in the Code that required the exterior of all wood framed buildings in Seismic Zone 4 to be sheathed in 1/2" plywood. The industry standard seems to be approaching this anyway. Also, I make it standard practice to add holddowns at the ends of all my shear wall, eve if there is no calculated uplift. I do this for two reasons. First, it is good practice and provides a nice foundation connection for your end post. Second, it helps to clarify in the contractor's (and inspector's) mind where your shear wall is intended to be. It sets a good example for them as well for future projects. The added cost of a couple of these holddowns is marginal. Good luck. Bruce Resnick, SE Parker Resnick Str. Eng.
