Western USA. Due to rarely used loophole in my county this is all legal if you DIY everything (no commerce so most regulation drops off) and I got permit explicitly exempting from code inspection.
Ah okay, that explains. I recently watched a video from a couple that did the same thing, but still made some minor mistake (not technical, but a little bureaucratic mistake) and had to rebuild it or something. I guess it had to do with the surface area.
Did you build with wood?
