“Where’s the R40 insulation?” “This is a 3-season cabin unoccupied 75% of the time. Or the insulation is weak, but the structure and windows are small, so it’s actually far more efficient than an R40 mansion”
“Where’s the septic field?” “The toilet is for guests (100flushes/yr) into a holding tank, pumped out yearly. I use the outhouse”
“Where’s the 20A circuits in the kitchen?” “I have 1 socket for 1 appliance, everything else is gas”
“Why aren’t there sockets every 10 feet?” “The whole point is to NOT have dozens of gizmos here”
“Your shower doesn’t drain into an approved gray-water system” “I can wash my car/shower outside but can’t shower with a bucket indoors?”
“This doesn’t meet min sqft requirements” “I built all the sqft I need, I’ll spend a half my time here hiking and fishing”
Crap like that.
One whole reason to build out in the boondocks is to build as you like. So it’s kind of beside the point, I think.
On the other hand if you want to build to some code, no one is stopping you either, so there is that.
