Off-Grid Living in Banner County, Nebraska

I'll be straight with you: Banner County, Nebraska is one of the toughest places I've researched for off-grid rules simply because there's almost nothing published online at the county level. Banner County (county seat Harrisburg, population under 700) doesn't have its code hosted on Municode, eCode360, or American Legal, and the county's own site doesn't post a zoning map, comprehensive plan, or building permit fee schedule. So a lot of what follows is the Nebraska state baseline, with a clear flag on what's actually confirmed for the county versus what you need to call and ask about.

Zoning. Nebraska law lets counties adopt zoning, but doesn't force them to. The state legislature's enabling statute (23-114.03) says a county board can only adopt or amend zoning after adopting a comprehensive plan, and counties even get to decide whether farmstead residence buildings fall under zoning at all. I could not find an official Banner County zoning ordinance or map anywhere online. That means I genuinely don't know if Banner County has adopted zoning. You need to call the County Clerk's office and ask directly.

Dwellings, tiny homes, RVs. No county-specific rule turned up. If Banner County does have zoning in force, state law says building permits (including sanitation and sewage plans) are required to conform to it, but that's conditional on zoning existing, which isn't confirmed.

Building permits and codes. Same story, no adopted building code or fee schedule found for Banner County. This is a call-the-Clerk situation.

Septic and composting toilets. This one I can actually answer with confidence, because septic is controlled at the state level regardless of what the county does. Nebraska's Department of Environment and Energy (DEE) regulates all onsite wastewater treatment systems under its Title 124 program, and only certified installers, engineers, or registered environmental health specialists can site, design, or build one. Small counties like Banner without their own health department typically route septic permitting straight through DEE, though I couldn't confirm that specific handoff on an official Banner County page.

Greywater. No county ordinance found; state Title 124 wastewater rules apply by default.

Rainwater harvesting. No Banner County rule found either way, and no statewide ban identified. I'd call it unclear rather than assume it's fine.

Wells. Well registration is handled through the state DNR, with different fees depending on pump capacity, and wells over 50 gallons per minute may also need a local Natural Resources District permit. I could not confirm which NRD actually covers Banner County, so that's another call to make.

Utility disconnection. No statewide or county law forces a grid or sewer hookup that I could find, but you're still on the hook for a compliant septic system under state rules no matter how off-grid you go.

Bottom line: Banner County is thin on published rules, so plan on phone calls before you plan on land.
