Off-Grid Living in Cheyenne County, Nebraska

I've been digging through official sources on off-grid living rules for Cheyenne County, Nebraska (seat: Sidney), and I want to be upfront: this is a county where a lot of the specific answers just aren't published online, so I'm laying out what I found and what I couldn't confirm.

Zoning. Cheyenne County does run a Planning & Zoning Committee, and the county publishes a "Comprehensive Plan" and zoning rules on its own site. That confirms zoning exists and matters here, but I couldn't find the district-by-district text online that would tell you whether raw-land occupancy (living in an RV or tiny structure on vacant land) is allowed in a given zone. You'd need to call the Planning & Zoning office directly for that.

Dwellings, tiny homes, RVs. I found nothing Cheyenne-County-specific here. Nebraska law lets county boards adopt building/construction codes covering houses and trailers, so that statutory framework applies by default (inherited from the state), but I don't have confirmation of what Cheyenne County itself has adopted.

Building permits. The county clearly handles permitting through its offices, but I couldn't pin down which specific building code edition is adopted. Not confirmed.

Septic and composting toilets. This one's clearer: septic systems statewide, including in Cheyenne County, are regulated by the Nebraska Department of Environment and Energy (NDEE) under its Title 124 Onsite Wastewater Treatment Systems program. Anyone doing percolation testing, installs, or repairs needs state certification (unless they're a licensed engineer or environmental health specialist). The state's own guidance notes local government rules can apply on top of that, but I couldn't find a Cheyenne County health department septic page to confirm what, if anything, the county adds.

Greywater. No county-specific rule found; the NDEE state framework applies by default, meaning greywater generally needs to run through a permitted system rather than being freely dispersed.

Rainwater harvesting. No Cheyenne County ordinance addressing rain barrels or cisterns turned up, and I found no statewide ban either, so this looks open, but it's not something I can confirm as officially sanctioned at the county level.

Wells. This is regionally administered: Cheyenne County sits inside the South Platte Natural Resources District (SPNRD), which also covers Deuel and Kimball counties. Nebraska's baseline rule (from DNR) is that low-capacity wells (50 gpm or less) mainly need registration, while higher-capacity wells may need an SPNRD permit before registration. Well construction standards themselves come from state health rules (Title 178).

Utilities. I found no ordinance requiring or forbidding grid/sewer hookup for occupancy in Cheyenne County. Off-grid living appears permitted, but your septic and well still have to comply with the state rules above.

Bottom line: zoning and permitting run through the county, wells run through SPNRD, and septic runs through NDEE at the state level. For anything county-specific I couldn't confirm, call the Planning & Zoning office before you buy land or build.
