I wish we could. The Code is State adopted and we can only be more strict. None of our local guys are going to have rescheck. We don't either and good luck on getting the chip counters to get it for us. The R-20 in the walls with 2x4's seems to be only a foam if they don't want to do the continuous on the outside.
With the continuous on the outside an EFIS is ok for the stucco'd look but if they want brick not sure you can find anything in manu. inst. instructions for installing brick ties to foam.
2x6 walls still only give you R-19 not 20 so lots of questions and not sure I have a good answer other than spray foam which is not very dollar friendly so contractors are barking. Hoping we are missing something but not sure we are.
