Off-Grid Living in Custer County, Nebraska

I've been digging into what off-grid living actually looks like in Custer County, Nebraska, and here's the honest rundown based on what the county and state have published.

Zoning comes first. Unlike some rural Nebraska counties that never adopted zoning at all, Custer County did, back in 2004, and the Custer County Planning Department administers it. That means before you erect, move, or structurally alter any building, including a single off-grid house, you need a Zoning Permit from the County Zoning Administrator. This is countywide, but keep in mind incorporated towns inside the county, like Broken Bow, Callaway, or Anselmo, run their own separate municipal codes that I have not researched here. If your land is inside city limits, different rules apply.

Tiny homes and RVs as dwellings aren't specifically addressed in what I could find on the county's site. The zoning permit list mentions "houses" and additions, but there's no published county standard on minimum square footage or living in an RV/trailer full-time. Nebraska generally leaves this kind of detail to county discretion, so I'd call the Zoning Office directly rather than assume either way.

Building codes: The county requires the zoning permit, but I couldn't confirm whether Custer County has adopted its own residential building code (like the IRC) on top of whatever the state defaults to. Don't assume there's no code just because the county page doesn't spell it out.

Septic is where things get firmly regulated, but at the state level. The Nebraska Department of Environment and Energy (NDEE) governs onsite wastewater treatment systems under its Title 124 rules, and you need a permit from NDEE before any septic construction, alteration, or repair. Whether Custer County's own office handles the local site evaluation or defers entirely to the state, I couldn't confirm. Composting toilets as a legal substitute for septic weren't addressed anywhere I found, so treat that as an open question to ask about directly.

Greywater reuse without treatment isn't allowed under NDEE's Title 124, and I found no county-level exception or addition to that.

Rainwater harvesting appears to have no specific rule at either the state or county level, so it looks permitted by default, but that's based on absence of a prohibition, not a clear green light.

Wells fall under Nebraska DHHS well-construction standards, and groundwater use often runs through your local Natural Resources District. Custer County overlaps several NRDs, so which one applies depends on your exact parcel, something you'd need to check by address.

Going fully off-grid, disconnected from utilities, looks workable in principle since nothing forces a grid or municipal hookup on unincorporated land. But you still have to clear the county's zoning permit and get your wastewater system NDEE-compliant. Whether any incorporated town within the county requires hookups is a separate question I haven't confirmed.

Bottom line: Custer County has real zoning teeth, more than people expect from rural Nebraska, so calling the Planning & Zoning office early is worth it.
