How Does The U.S. Regulate Off-Grid Living?
Outhouses are generally considered off-grid modifications for the release of human waste. Few states make the distinction between the two extremes of legal and illegal; most have adopted an approval or permit system. Generally speaking, if the area is highly metropolitan, has a large population, or is concerned about water usage, their laws will be more strict in regard to outhouse installation.
For off grid-living, there are different types of outhouse toilets. Traditional outhouses, bucket toilets, compostable toilets, and tank/septic systems are all popular options. Compostable toilets should have NSF certification to be used
