Do you need a building permit in Juab County, Utah?

Yes. Juab County Planning and Zoning permits and inspects construction activity in the county¹³. Utah's State Construction Code governs regulated construction, alteration, remodeling and repair, subject to statewide and local amendments and statutory exceptions¹³. A qualifying structure used only for agriculture and not for human occupancy is exempt from the State Construction Code, but plumbing, electrical or mechanical permits may still be required, and parcel-location limits apply¹². For permitted structures, Juab County prohibits occupancy until the final inspection is complete and a certificate of occupancy has been issued¹⁴.

Who is the Juab County building department, and how do you reach it?

Juab County Planning and Zoning is the county building-permit and inspection office³. The office is at 160 N Main Street, Office #117, Nephi, UT 84648, and its phone number is 435-623-3400³. The same department administers county planning and zoning, so it is the first call for permit applicability, parcel zoning, setbacks, allowed uses and application forms³. The county's published application checks acreage, frontage, plans, zoning, water, wastewater, addressing and encroachment approvals, and an issued permit expires if work does not start or remains suspended or abandoned for 180 days¹⁵.

Does Juab County have zoning?

Juab County administers planning and zoning and publishes a Land Use Code and zoning map for county-administered land¹⁶⁶. Incorporated municipalities may administer their own land-use rules, so confirm whether a parcel is inside city or town limits before relying on the county map⁶. The county's accessible materials did not confirm a single countywide minimum dwelling size, minimum lot size, setback distance, lot-coverage cap or building-height limit; ask Planning and Zoning for the standards in the parcel's district³. Subdivisions in unincorporated Juab County are regulated, including acreage and road requirements, but the complete current thresholds and exemptions were not confirmed¹⁷.

How do septic permits work in Juab County?

Central Utah Public Health Department is the septic authority for Juab County⁴¹⁸. No part of an onsite wastewater system may be built until the health department issues a construction permit; the application package includes soil classification, a site plan, system design and the applicable fee¹⁹. The listed permit fees are $600 for a conventional system, $900 for an alternative system and $200 for repair or replacement¹⁹. The installed system must be inspected before it is backfilled⁷. Only 17% of county soils are rated without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency rather than assuming a standard system will work²⁰.

Can you live in an RV or tiny home on your land in Juab County?

Juab County's accessible official materials did not confirm whether long-term residential RV occupancy or temporary private-land camping is allowed in unincorporated areas; ask Planning and Zoning for a parcel-specific answer before moving onto the land³. Utah's RV-park sanitation rule covers RVs and qualifying tiny houses in RV parks, not the separate question of living in one on a private parcel²¹⁸. A manufactured home cannot be excluded from an area where a single-family residence is permitted, but it must use a compliant permanent foundation and follow the same applicable land-use rules, building codes and restrictive covenants²².

Building a home in Juab County: the steps, in order

First — call Juab County Planning and Zoning to confirm jurisdiction, zoning, allowed use, dimensional standards and the building-permit submittal for the parcel³⁶.

Second — secure a water source; a private well requires a valid water right and a state Start Card before construction¹¹.

Third — obtain the onsite wastewater construction permit from Central Utah Public Health Department before septic work begins²³¹⁹.

Fourth — resolve driveway access: county roads follow Juab County spacing standards, while a new connection to a state highway requires a UDOT conditional access permit²⁴²⁵.

Fifth — obtain the county building permit, complete required inspections, and do not occupy the structure until final inspection and issuance of the certificate of occupancy¹⁵.

What should you check before buying land in Juab County?

Water comes first in this dry county: annual precipitation averages 11.7 inches, and severe drought has occurred in 37.9% of years²⁶²⁷. A private well needs both a valid water right and a Start Card, so verify the water right before treating a proposed well as buildable infrastructure¹¹. Septic feasibility also deserves an early site review because only 17% of soils are rated without severe limitations for a conventional drain field²⁰. Confirm legal access and driveway geometry because Juab County limits access to county roads, and state-highway connections require separate UDOT approval²⁴²⁵. Finally, verify boundaries and access carefully because federal land makes up 72.7% of Juab County²⁸.

Watch-outs

Do not move into a permitted structure before Juab County completes the final inspection and issues the certificate of occupancy⁵.
The owner-builder exemption is an exemption from contractor licensing, not from building permits, inspections, zoning or trade requirements⁹¹⁰.
County building-permit fees and a current floodplain-development process were not confirmed; ask Juab County Planning and Zoning about both before finalizing a construction budget³.

Water rights & wells in Juab County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Utah’s water agency.

Closed to new supply

New water supply here generally requires a permit, an offset, or buying an existing right — a household well is not automatic.

Household wellPermit required — restricted

Utah has NO exempt domestic well — you must own a water right to drill any well, including a household well. In an open area you file a new appropriation, but because much of Utah is closed to new appropriation a newcomer typically must PURCHASE an existing water right and file a change application to move it to the new well.

Limit: ~0.45 acre-ft/yr indoor domestic (typical allocation); no statutory exempt-well quantity
