Off-Grid Living in Sevier County, Utah

Sevier County has no standalone off-grid ordinance, but its building-permit process requires sign-off from the power utility, Division of Water Rights, and Central Utah Public Health Department before a permit issues, effectively requiring an approved water source and wastewater plan.

Is it legal to live off-grid in Sevier County, Utah?

There is no outright ban on living off-grid in Sevier County, Utah - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are restricted. Plan around septic/wastewater (restricted) and disconnecting from utilities (restricted). Because these rules are set locally, confirm the specifics with Sevier County before you buy land or build.

Sevier County at a glance

Zoning & raw-land occupancy
RestrictedSevier County has countywide zoning adopted under Utah's enabling law, and unincorporated land is divided into zoning districts that spell out what uses and occupancy are allowed on a given parcel. There's no blanket rule found for tents or yurts on raw land, so whatever you want to do would need to be checked against the specific zone's land-use matrix with the county's Planning & Zoning office. source
Dwellings, tiny homes & RVs
RestrictedThe county draws a hard line between permanent dwellings and RVs or temporary structures. For example, in the GRF-20S zone, 'permanent recreational dwellings' are allowed but habitation is capped at nine consecutive months a year, manufactured homes (at least at the town level, like Annabella) must go on a permanent foundation within a set window, and RVs used as living quarters beyond a short period generally need a Conditional Use Permit tied to active construction of a permanent home. A tiny house on wheels would likely be treated as an RV, and this isn't confirmed for every zone or town, so check with the county or the specific municipality. source
Building permits & codes
RestrictedSevier County has adopted the standard suite of state construction codes (IBC, IRC, IECC, NEC, IPC, IMC, Fuel Gas Code, IFC), and any building over 120 square feet in the unincorporated county needs a permit approved by the Zoning Administrator and issued by the Building Official. Before that permit issues, the county requires a signature sheet with sign-off from the power utility, the Division of Water Rights, and the Central Utah Public Health Department. source
Septic & composting toilets
RestrictedYou have to sort out wastewater disposal before the county will issue a building permit. The Central Utah Public Health Department requires either a septic tank permit or proof you can connect to an existing sewer system, and this sits on top of the statewide onsite wastewater rule (Utah Administrative Code R317-4) that the state Division of Water Quality administers. Composting-toilet-specific rules weren't found on an official county or health department page, so that part is not confirmed, ask the Central Utah Public Health Department directly. source
Greywater reuse
Unclear - verifyNo Sevier County or Central Utah Public Health Department page specifically addressing greywater turned up in this research. The state's baseline greywater rule (R317-401) presumably applies since wastewater permitting is routed through the health department, but that link isn't confirmed locally, so it's worth asking the Central Utah Public Health Department how they handle greywater systems on permit applications.
Rainwater harvesting
Unclear - verifyNo Sevier County ordinance or webpage on rainwater collection was found, so the state baseline under Utah Code 73-3-1.5 (up to 200 gallons with no registration, more with free registration) appears to be what governs here, with no local variance identified. Worth double-checking with the county if you're planning a larger catchment system.
Private wells & water rights
RestrictedThe county requires proof of an approved water source, such as a well, before it will issue a building permit, and this ties directly into the state's water rights process through the Utah Division of Water Rights (part of the same signature-sheet requirement as septic). There's no separate county well ordinance identified beyond funneling applicants through the state's standard water right and Start Card process.
Living disconnected from utilities
RestrictedThere's no standalone off-grid living ordinance in Sevier County, but the building-permit signature sheet functionally requires proof of an approved water source, wastewater disposal, and even power utility sign-off (Utah Power and Light) before a permit will issue. That could complicate a fully grid-disconnected new build, though it's not explicitly framed as a prohibition on off-grid power, just something to work through with the Building/Planning office.

I've been digging into what it actually takes to live off-grid in Sevier County, Utah, and the short version is: the county doesn't have an "off-grid" ordinance you can point to, but its ordinary building-permit process functions as a pretty firm gatekeeper for anyone trying to disconnect from water, sewer, or power hookups.

Zoning. Sevier County has adopted countywide zoning under Utah's enabling statute (Utah Code 17-27a-505), so unincorporated land is divided into zones with their own rules on what you can build and how you can use the parcel. I didn't find a specific policy on pitching a tent or setting up a yurt on raw land long-term; that would fall under whatever the parcel's zone allows, so I'd call the county Planning & Zoning office before assuming you can just camp on your own dirt indefinitely.

Dwellings, tiny homes, RVs. The county draws a clear line between a permanent dwelling and a recreational vehicle. In at least one zone (GRF-20S), the code allows "permanent recreational dwellings" (cabins) but caps habitation at nine months out of the year unless it's hooked to an approved septic system. Manufactured homes and RV-as-residence rules I found were set at the town level (Annabella, for example, requires manufactured homes on a permanent foundation quickly after delivery), so incorporated towns may have their own stricter add-ons. A tiny house on wheels will likely be treated like an RV; RV parks countywide need a conditional use permit and state-approved waste disposal.

Building permits. The county has adopted the standard suite of international codes (IBC, IRC, IECC, NEC, IPC, IMC, fuel gas, fire code). Any building over 120 square feet in unincorporated county land needs a permit from the Building Official, and before that permit issues you need an "Unincorporated Area Signature Sheet" signed off by the power utility, the Utah Division of Water Rights, and the Central Utah Public Health Department.

Septic/greywater. Wastewater is handled by Central Utah Public Health Department as part of that same signature sheet, either a septic permit or proof of sewer hookup, under the state's onsite wastewater rule (Utah Admin Code R317-4). I found nothing county-specific on composting toilets or greywater reuse; the state's greywater rule (R317-401) presumably applies, but confirm locally.

Rainwater. No county-specific rule turned up. Utah's statewide law lets you collect up to 200 gallons without registering, more with a free registration, and that appears to be what governs here.

Wells and utilities. The Division of Water Rights has to sign off on an "approved source of water" before your permit is issued, tying straight into the state's well-permit and water-rights Start Card system. Because power, water, and wastewater sign-offs are baked into the permit process, a fully off-grid new build could hit friction, not because it's banned outright, but because the paperwork assumes you're hooking to something approved.

Bottom line: nothing here says "off-grid is illegal," but the permit pipeline is built around utility sign-offs, so plan on real conversations with the county and the health department before you buy land expecting to go fully independent.

FAQ

Common questions about off-grid living in Sevier County

Can I legally live off-grid on raw land in unincorporated Sevier County?

Not straightforwardly. The county's zoning ordinance controls what each zone allows, and a building permit, which requires water-source and wastewater sign-off, is generally needed for structures over 120 square feet, so check with the county Planning & Zoning office for your specific parcel.

Does Sevier County allow composting toilets instead of septic?

I couldn't confirm this on an official county or health department page. The county's building-permit process routes wastewater questions through the Central Utah Public Health Department, so ask them directly about composting toilet acceptance.

Do I need a permit to collect rainwater in Sevier County?

No county-specific rule was found. The statewide law allows collecting up to 200 gallons without registering, and more with a free registration, and that appears to be what applies here.

Can I drill my own well without going through the state?

No. The Utah Division of Water Rights has to confirm you have an approved water source as part of the county's building-permit signature sheet, so well permitting runs through the state's standard process.
