Sounds like a great idea !
For what it is worth,(from experience) I know in Mitchell County in the NC mountains you could do it with no problem, but prior to getting electricity you have to get a septic system installed and that requires the board of health doing a perk test and then showing you where it goes.
Start with the building inspector and he will tell you what it entails.
Other than the cost of a septic system, your total cost would be the board of health permit cost, the building inspectors permit, (that would be for your electric service), and your electric pole and cost.
