Off-Grid Living in Clark County, Nevada

Clark County, Nevada is a tough place to try to go fully off-grid, and I want to be straight with you about that up front. This covers the unincorporated county under the Department of Comprehensive Planning and Development Services. If you're inside Las Vegas, Henderson, North Las Vegas, Boulder City, or Mesquite city limits, those cities run their own separate codes and this brief doesn't apply.

Zoning and land occupancy. Clark County zoning generally prohibits living in an RV or other non-permanent structure on raw land outside a licensed RV park. If you want an exception, the Department of Comprehensive Planning has a process for a Special Use Permit, Waiver of Standards, Variance, or Zone Change, but it's a discretionary application heard by the Planning Commission (appealable to the Board of County Commissioners), not a guarantee.

Dwellings, tiny homes, RVs. County code (Title 30) doesn't recognize an RV or a temporary structure as a permanent dwelling. There's a "Temporary Dwelling" category, but it's meant for things like living in an RV while your damaged home is rebuilt, not for a permanent lifestyle. Long-term RV or tiny-home living on a lot is treated as a zoning violation.

Building permits. If you build a permanent structure, Clark County's Building & Fire Prevention Department enforces its own adopted versions of the ICC model codes (building, residential, electrical, plumbing, mechanical, energy). Small accessory structures may be exempt from permits below a size threshold, but zoning setbacks and height limits still apply regardless, so confirm specifics with that department before assuming anything is exempt.

Septic and composting toilets. Septic systems (ISDS) in Clark County are permitted by the Southern Nevada Health District, not a generic county health office. SNHD will only issue new septic permits where the lot is a set distance from an available sewer connection, and you'll need to show your water source is approved, either a water-utility letter (Las Vegas Valley Water District or Moapa Valley Water District) or a valid domestic well. I could not confirm any SNHD or county page that treats composting or waterless toilets as an approved stand-alone substitute, so ask SNHD directly if that's your plan.

Greywater and rainwater. I found no Clark County-specific greywater ordinance; the county has adopted the Uniform Plumbing Code, which does have a greywater chapter, but how the county actually implements it locally isn't confirmed, so check with Building & Fire Prevention. Rainwater harvesting for non-potable use is allowed under Nevada's statewide law, and I found nothing at the county level restricting it further.

Wells and water rights. Clark County has no separate well permit; it's entirely a state matter run by the Nevada Division of Water Resources. Domestic wells are exempt from the state's regular water-right permitting process, but a well generally can't be drilled if the parcel could instead be served by a public water utility, a real constraint across much of the Las Vegas Valley. SNHD septic applications will also ask for a well log and water-rights documentation where a well is involved.

Utilities. Nothing stops you from running solar or off-grid systems on a legally permitted home, but county code defines a legal, habitable building as one with potable water and sanitation among other services. Living unpermitted on raw land or full-time in an RV outside the rules above is the actual risk here, not the utilities themselves.
