Just checked with codes office. Says I can get a permitted septic system first then apply for a permit to bring power there. Then I can camp. He made it sound as if I do those things, it's not a problem. But even those will cost thousands. And if I build a cabin, I'm sure the property tax will increase. And I still hate to invite tax officials there if I don't have to
That's why I was considering just a self contained camper w/o any hookups or permit, no electricity nor septic (except maybe a home made non permitted collection system on the sly). And yes, I know that's illegal and not "green". But it's better than what we do now, i.e. going in the woods. Frankly in my area, I doubt if anyone would even know nor care. I'm just talking about staying a day or two occasionally not living there. Code enforcement is pretty minimal. (Unless I open that door by requesting a permit)
So let me get this right. I can buy a small camper with propane tanks, water tanks, and sewage tanks and that would allow me to just park it and camp. Propane could heat enough water for a few showers and the batteries could power minimal lighting supplemented with a generator in a pinch. Then I just would have to dump grey water and my sewage as need be. In general, how long can you go between dumps (and I realize that is a "it depends question" but just a guess for normal use for two people with normal sized tanks. Grey water doesn't bother me. But sewage of course would have to be carried away or piped to a septic tank or similar system.
So as much as I would enjoy building a rustic cabin or tiny house, to do this certainly would require me to follow the rules and permit the process. And that I just don't want to do. Nor do I want to camp in a tent. So that leaves either a camper or a mobile shed. And a camper is certainly easier at least short term.
