Off-Grid Living in Jefferson County, Nebraska

If you're thinking about going off-grid in Jefferson County, Nebraska, the first thing I want to clear up is that this county isn't one of those "no zoning, do what you want" rural counties in Nebraska. Jefferson County has adopted countywide zoning (new regulations effective 2026, per the county's Planning & Zoning Administrator page), and that means any construction, parcel split, or parcel combination has to go through a zoning permit process before you break ground.

Zoning and dwellings. The county's Permitted Use Zoning Permit application covers districts like Agricultural (AG), Agricultural Residential (AGR), Industrial (I), and Commercial (C). Notably, the form asks whether the structure will be "portable" and whether anyone plans to live in it, so tiny homes, RVs, and cabin trailers used as residences are on the county's radar. I did not find specific minimum square footage rules or an explicit RV-as-permanent-home policy, so that's a "confirm with the county" item, not something I can state as fact.

Building permits. A zoning permit (with a fee shown on the county's form) is required before construction starts, and the form itself warns of a late penalty if you build first and permit later. I could not confirm whether Jefferson County has adopted its own building code on top of that, or simply defaults to the Nebraska state building code, which the state adopts and allows counties to localize as long as it stays consistent with state minimums.

Septic and greywater. I found no county-level septic or environmental health office, so this falls to the State: Nebraska's Department of Environment and Energy (NDEE) runs the Onsite Wastewater Program under its Title 124 rules and issues permits statewide, including via the state's One Stop portal. Greywater reuse is not separately addressed by the county, so it inherits that same state-level restriction, and composting toilets aren't addressed anywhere I could find, county or state.

Rainwater. Genuinely unclear here. No county rule, and the state baseline is thin too, so I'd call this a gray area worth a direct question to the zoning office.

Wells. Wells statewide follow Nebraska DHHS design standards, and anything pulling more than 50 gallons per minute needs a Natural Resources District permit. I couldn't confirm which specific NRD covers Jefferson County in this research, so check with the county or Nebraska DNR's locator.

Off-grid living generally. I didn't find any outright ban on disconnecting from utilities, but because zoning permits ask directly whether a structure will be lived in, going off-grid doesn't mean going unpermitted. You'll still need to satisfy zoning, plus a compliant well and septic setup.

Bottom line: Jefferson County has real zoning teeth, so start with the Planning & Zoning office before you buy land or build.
