Off-Grid Living in Campbell County, Wyoming

I've been digging into Campbell County, Wyoming for folks eyeing off-grid land, and here's the honest picture: this isn't one of Wyoming's "no permit, no questions" counties. Campbell County has its own building code, its own building/electrical/plumbing permitting, and delegated state authority to permit septic systems. That's a meaningfully more hands-on setup than a lot of rural Wyoming counties.

Zoning. There's no countywide zoning here, per Campbell County's Planning & Zoning Division, but most subdivisions have their own zoning classifications, and zoned parcels need a Zoning Certificate before you build or change land use. Before you buy, check the county's zoning web map for the specific parcel, since the answer really does vary lot by lot.

Dwellings, tiny homes, RVs. What counts as a legal dwelling depends on the zoning district assigned to that parcel, per the county's Chapter 7 zoning rules. I couldn't confirm specific tiny-house or RV occupancy rules from official sources, so if that's your plan, call Planning & Zoning directly and ask about your parcel's classification.

Building permits. The county's Building Division, under Public Works, administers its own construction rules and requires permits for building, plumbing, and small wastewater systems. A code official can issue stop-work orders for noncompliance. This applies countywide, with the City of Gillette and Town of Wright handling their own enforcement separately.

Septic. This is a big one: Campbell County holds delegated authority from the Wyoming DEQ to permit residential septic systems under 2,000 gallons per day, so unlike counties where DEQ permits directly, here it's the county's own program. Permits and inspections are required.

Greywater. No county-specific rule found, so the state DEQ's permit-by-rule framework applies: you notify DEQ's Water Quality Division, keep greywater on your property, avoid floodplains and runoff, and stay under the state's volume cap.

Rainwater harvesting. No Campbell County ordinance found either way. The state baseline from the Wyoming State Engineer's Office applies, and I found nothing barring it locally.

Wells. The Wyoming State Engineer's Office regulates well permitting and construction statewide, and Campbell County's own building permit application points applicants straight to that office. If you're sharing a well, the county requires a notarized, recorded Shared Well Agreement.

Utilities. Nothing in the county's rules mandates connecting to grid utilities, and the building permit application accommodates wells and alternative power setups. Confirm specifics on "Alternative Power" provisions with the Building Division, since I couldn't pin down the full text.

Bottom line: Campbell County is workable for off-grid living, but plan on real paperwork for building, septic, and wells. Call the offices below before you buy or build.
