Off-Grid Living in Knox County, Nebraska

I'll be upfront: Knox County, Nebraska surprised me a bit in the research. A lot of rural Nebraska counties have no zoning at all, which off-gridders love, but Knox County actually has countywide zoning run by its own Planning, Zoning & Floodplain Department. That changes the game for anyone hoping to just buy land and quietly set up a cabin or trailer.

Zoning and raw land. The county's Zoning Resolution lets the Planning, Zoning & Floodplain Department regulate the location, size, and type of structures across zoning districts, and it specifically calls out tents, cabins, house trailers, and automobile trailers as things it covers. So parking a trailer or camping long-term on raw land isn't a gray area here the way it is in unzoned counties, it falls under the permitted-use table for whatever district your land sits in. Definitely check the zoning map before you buy.

Dwellings, tiny homes, RVs. Same story: the county's zoning language explicitly covers these structure types. Layered on top, Nebraska's Public Service Commission sorts "tiny houses" into HUD-manufactured, modular, or RV/park-model categories, each with different construction-code rules. Which category you land in affects how the county treats siting and permitting. I couldn't confirm specific minimum square footage rules for Knox County beyond the general zoning framework, so ask the zoning office directly.

Building permits. A county construction permit is required before you build, and the office told me (through the published permit form) that work cannot begin until that permit is approved. There's a published fee schedule, but I'm not going to guess at numbers, call the office or check their site. If you're in the Spoon Valley Lake or Oak Run sanitary districts, you'll need their sign-off too, on top of the county's. Floodplain parcels need a separate Floodplain Development Permit.

Septic and greywater. I didn't find a Knox County health department page for onsite wastewater, which tells me the county leans on the state. Nebraska's Department of Environment and Energy (NDEE) runs septic permitting statewide under its Title 124 rules, and that's your baseline here. Greywater specifically isn't addressed locally that I could find, so the state framework governs by default.

Rainwater. No prohibition found at county or state level in this research, but I couldn't confirm any Knox County-specific catchment permit either. Treat it as unclear until the zoning office says otherwise.

Wells. Well permitting runs through the local Natural Resources District, not the county health department. Knox County touches the Lewis & Clark NRD (plus Lower Elkhorn and Lower Niobrara). Nebraska rule: wells over 50 gallons per minute need state registration and an NRD permit; domestic and livestock wells are also capped at 50 gpm unless permitted otherwise. Some residents skip individual wells entirely and hook into the Cedar-Knox Rural Water Project, an NRD-owned surface water system serving parts of the county.

Off-grid utilities generally. I found no blanket county rule forcing hookup to grid power or municipal sewer. But "off-grid" doesn't mean "off-permit" here, you'll still need the zoning/construction permit and a compliant septic system regardless of your utility choices.
