Off-Grid Living in Juab County, Utah
Juab County actively zones unincorporated land with large minimum-acreage rules in many areas, and its building permit process requires proof of an approved water source and a wastewater permit before a permit is issued. Several specifics, like tiny home/RV treatment, septic administration, and greywater/rainwater rules, aren't confirmed at the county level and likely default to state rules, so calling the county Planning & Zoning office directly is the safest first step.
Is it legal to live off-grid in Juab County, Utah?
There is no outright ban on living off-grid in Juab County, Utah - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is not clearly documented online, so confirm it locally, and building permits are restricted. Plan around septic/wastewater (not clearly documented online, so confirm it locally) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Juab County before you buy land or build.

I've been digging into Juab County, Utah for anyone thinking about buying raw land out there and going off-grid, and here's where things stand based on what I could actually confirm.
Zoning comes from the county, and it's not a free-for-all. Juab County has a countywide Land Use Code, administered by a Planning Commission and a Zoning Administrator who interprets the ordinance and the zoning map. Historically, the county has required big minimum lot sizes on unincorporated agricultural land, something like 50 acres of irrigated land or up to 160 acres of semi-arid land per home, with 20-acre lots allowed in some zones. So "just buy 5 acres and build a cabin" isn't automatically a thing here; you need to check the zoning designation on the specific parcel. Incorporated towns like Nephi, Eureka, Mona, Levan, and Rocky Ridge can also have their own ordinances layered on top (Nephi actually contracts with the county's planning department for plan review).
Building permits are tied directly to water and wastewater approval. This is the big one. Juab County's own building permit application requires sign-off on acreage/frontage requirements, zoning, "Water Verified," a "Water Liability Release," and a "Waste Water Permit" box, all before the county will issue a Building Permit Fee plus the state's 1% fee. In plain terms: the county won't let you build without proving you have an approved water source and an approved way to deal with wastewater. I couldn't find a specific county page addressing tiny homes, yurts, or RVs as dwellings, so treat that as unconfirmed and inherited from the general state framework, where RVs are typically not treated as permanent dwellings.
Septic, greywater, and rainwater rules are murky at the county level. I could not locate a dedicated Juab County health department page for septic or onsite wastewater permitting, though the wastewater-permit checkbox on the building form confirms some septic approval process exists locally. My best guess is this runs through whatever multi-county health district serves Juab, but I couldn't confirm which one, so call the county Planning office to ask. Greywater and rainwater harvesting rules aren't addressed anywhere I found at the county level either, so those likely default to Utah's statewide rules (a permit through the local health department for greywater, and fairly permissive rainwater collection rules under state law).
Wells run through the state, not the county. Well drilling and water rights anywhere in Utah, including Juab County, go through the Utah Division of Water Rights and the State Engineer's office. The county's building form also wants proof of an approved water source before it'll sign off, so even if your well is state-approved, the county still checks it.
Living fully off-grid (no utility hookups) isn't explicitly addressed, but the building permit's insistence on verified water and a wastewater permit strongly suggests the county won't issue occupancy without those two pieces in place, even if you're generating your own power.
Bottom line: call the county before you buy land.

Planning a build in Juab County
The rules above decide what you may build. The numbers below decide what you will have to build, and they come from this place rather than from a national average.
Solar: size for the worst month, not the average
Juab County averages 5.7 peak sun hours a day across the year, but its worst month averages 3.5. That is a drop of about 39 percent. An array sized on the annual figure will therefore come up short in the worst month by roughly that much, in the season when lights, pumps, and heating fans all run hardest.
Put another way, meeting the same daily load in the worst month here takes about 1.6 times the array that the annual average implies, or a generator and the fuel budget to run it. Neither is wrong; what is wrong is discovering the gap in the first winter. The solar calculator runs this arithmetic against your own load list, and lesson four covers building that list before buying panels.
Heat: 6,154 heating degree days
That is a genuinely cold heating season, where losing heat for a few days in winter risks the plumbing and the building itself. Heating demand at this level dwarfs everything electrical in the house, which is why almost nobody here heats with electricity from a battery bank.
As a rough order of magnitude, a small, reasonably insulated cabin heated mainly with wood in a climate like this tends to burn in the region of 5.1 cords a season, with the real figure swinging widely on insulation, house size, and how you burn. Treat that as a bracket for planning your woodshed rather than a promise, split and stack a season ahead, and check with a moisture meter before burning. The firewood calculator and heat-loss calculator narrow it down from your own building.
Water: what the roof would actually catch
Juab County receives about 15.3 inches of precipitation a year. A 1,000 square foot roof here would shed on the order of 8,107 gallons a year at a realistic 85 percent collection efficiency, before any losses to first-flush diversion, evaporation, or overflow in a heavy storm.
The annual total is the easy part. What sizes a cistern is the longest dry stretch, because catchment is seasonal almost everywhere and a tank that covers the average year can still run empty in August. Check the local rules too: rainwater harvesting is regulated in some states even where it is broadly allowed. The rainwater calculator works from your own roof and rainfall pattern, and lesson three covers why water is chosen before power.
Snow: 40 inches in an average year
At this level, snow is a design input rather than a nuisance. It sets the roof load your structure has to carry, it decides where a metal roof may safely shed and therefore where doors, propane tanks, and walkways must not be, and it buries a ground-mounted array at exactly the time of year the array matters most. It also makes the driveway a system: how it is graded, where the snow is pushed, and who clears it when you cannot.
Distance is part of the plan
Measured straight line from the center of Juab County: the nearest fire station is about 14.3 miles away (Nephi Fire Department), the nearest hospital is about 15.6 miles away (Central Valley Medical Center), the nearest supermarket is about 15.0 miles away (Mt Nebo Market). Road miles will be longer, and in winter longer again.
The fire distance is worth noting before you buy rather than at renewal: insurers commonly rate rural property partly on how far it is from a responding station and from a water source, and some decline off-grid or owner-built structures outright. Ask an agent who writes rural policies what they would need to see, while the answer can still change what you build. Lesson eleven covers the insurance and financing side.
The hospital distance sets what your first aid kit and your medical plan have to cover in the gap, and it is the number to think about before anyone in the household depends on refrigerated medication or mains-powered equipment.
Confirming this for your own parcel
On this page 5 of the eight topics are recorded as unclear or as varying within Juab County: what counts as a dwelling, septic and sewage, greywater, rainwater harvesting, mandatory utility connection. Those are the calls to make first, because they are the ones where a general answer cannot be trusted for a specific parcel. Ask for the answer in writing where the office will give it, and note the name and the date where it will not.
Where a topic is recorded as settled here (zoning, building permits and codes, wells and water rights), the source is cited further down this page. Sources go stale, ordinances get amended, and this site logs corrections publicly rather than editing them away, so if you find something here that no longer matches the county, the corrections page is how to say so.
Before any of those calls, walk the parcel with the land walk checklist and take the questions for the county with you. The parcel check pulls flood, wetland, slope, and access data for a specific parcel and shows its sources, which is a good way to arrive at the office with the questions already framed. Lesson two is the wider version of this list.

FAQ
Common questions about off-grid living in Juab County
Is it legal to live off-grid in Juab County, Utah?
There is no outright ban on living off-grid in Juab County, Utah - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is not clearly documented online, so confirm it locally, and building permits are restricted. Plan around septic/wastewater (not clearly documented online, so confirm it locally) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Juab County before you buy land or build.
Can I build a small cabin on a few acres in unincorporated Juab County?
Maybe not, depending on the zone. The county's Land Use Code has historically required large minimum acreages, sometimes 20 to 160 acres, for a single home on unincorporated land, so check the specific parcel's zoning with the Juab County Planning & Zoning Department before buying.
Does Juab County require a septic permit before I can build?
The county's own building permit form includes a Waste Water Permit checkbox as a prerequisite, so yes, some form of wastewater approval is required, though I couldn't confirm which health authority issues it. Ask the Planning & Zoning Department directly.
Can I drill my own well in Juab County?
Well permitting is handled at the state level by the Utah Division of Water Rights, not the county, but Juab County's building permit process also requires proof of a verified water source before issuing a permit.
Are tiny homes or RVs allowed as permanent residences in Juab County?
This isn't specifically addressed in the county documents I found, so it's unclear. It likely defaults to Utah's general treatment of RVs as non-permanent dwellings, but confirm with the county directly.
Can I live completely off-grid with no utility hookups in Juab County?
There's no explicit written policy against it, but the building permit process requires proof of an approved water source and a wastewater permit, which suggests full occupancy approval hinges on those two things regardless of your power setup.
