My regional building department has taken a stance on ICF's that they are not allowed to have stucco applied directly to the Styrofoam. This is rather unfortunate for me, as I already have lath over my bare Styrofoam walls.

To be blunt, these people are morons who explained to me in condescending tones that the reason is to protect me and my family against water seeping in behind the stucco, freezing and causing the stucco to crack. My argument that the Styrofoam is more pliable than stucco, and if it was to expand, would merely expand into the Styrofoam fell on deaf ears. Every ICF manufacturer makes the statement that exterior coverings can be made directly to the ICF block, but nobody has the critical ICC-ES report to back the statement up.
I've had numerous ICF manufacturers call them to no avail... so I'm toast.
I think it's Margarita night.
