Did the metal building company say stucco of any kind would be ok? Riverside can experience serious earthquakes and metal buildings are often designed to have huge deflections under seismic loads, as much as 1:40. So the two concerns with stucco would be 1) how will all of that weight impact the seismic design of the structure, and 2) how will the stucco remain attached and unbroken during a quake?
Just considering wind loading I believe pre-engineered metal buildings (PEMB's) often have a greater allowable deflection of components (i.e. girts) than the allowable deflection of facing materials such as EIFS's (such as "Dryvit" which is a trade name") or brick and the like. Probably additional cost to the steel building to get the allowable building deflections down to the allowable that can be handled by the those types of facing materials.
