Off-Grid Living in Oliver County, North Dakota

I've been digging into what it actually takes to live off-grid in Oliver County, North Dakota, and here's what I found, plus where the record runs dry.

Zoning. Oliver County has a countywide zoning ordinance, adopted under the authority the state gives counties in NDCC chapter 11-33, administered by an appointed Planning & Zoning Board that answers to the Board of County Commissioners. It covers unincorporated land, not the City of Center or its one-mile extraterritorial ring, which follow city rules instead. The ordinance was recently amended (effective September 2025), and I'd treat it as a moving target, so pull the current version rather than trusting a cached copy.

Dwellings, tiny homes, RVs. I could not confirm a minimum dwelling size or a clear RV-as-permanent-residence policy in the materials I reviewed. The ordinance does talk about road-frontage and access requirements for any parcel. If you're planning a tiny home or RV as a full-time residence, call Planning & Zoning before you commit to a site.

Building permits. The county issues building permits, and routine buildings (no variance needed) go through the Planning and Zoning Board with sign-off from the County Commissioners. Construction itself falls under the statewide North Dakota State Building Code. I don't have a fee schedule or inspection timeline from an official source, so get that straight from the County Auditor's office.

Septic and composting toilets. This is state-plus-local: the North Dakota Department of Environmental Quality licenses installers statewide (NDCC 23.1-07.1) and sets minimum design standards, but the actual permit, site evaluation, and inspection happen through your local district health unit. I couldn't confirm which district health unit covers Oliver County specifically, so start with the County Auditor or NDDEQ to get pointed to the right office.

Greywater. This is genuinely unresolved. No Oliver County ordinance language addresses it, and it's a gray area statewide too. My advice: assume it'll get treated like septic wastewater until a local health unit tells you otherwise.

Rainwater harvesting. Nothing in the county ordinance restricts it, so this appears to follow the general state baseline of being allowed. Bigger cisterns or underground storage might trigger the building permit process, so check with Planning & Zoning if you're going big.

Wells. Well construction is regulated at the state level (NDAC 33.1-18-01) through licensed contractors under the ND Department of Water Resources. North Dakota doesn't regulate private well placement or water quality itself. Oliver County also has its own SW Water Board for local water-resource matters.

Utilities. I found no requirement in the zoning ordinance forcing you to connect to grid power or public utilities. That lines up with the state baseline, but I couldn't review the full ordinance text, so double-check with Planning & Zoning before you finalize an off-grid build.

Bottom line: Oliver County gives you real running room to go off-grid, but several details (dwelling size, RV occupancy, the exact health unit for septic) just aren't nailed down in what's publicly posted, so a phone call or two up front will save you headaches later.
