I was just reading old posts, such as this one, and I felt compelled to chime in.
I would say that its generally true that rural counties will have more open building codes/enforcement then in a
city, however, straw bale construction is becoming pretty widespread. Another thing is to change the way you speak/think about straw bale houses. Since most houses that we call straw bale are actually post and beam with straw bale infill, phrase your
project as a "post and beam timber house with cellulose insulation" sounds better to an insurance agent or building department, since that is exactly what it is. I think when you use the term "straw bale house" it brings all sorts of preconceived notions to the mind.
