Building permits, zoning and land rules in Juab County, Utah

Juab County Planning and Zoning issues building permits and inspects construction in unincorporated Juab County; Mona and Levan administer their own building permits inside their boundaries^3,11,12,13. Septic permits remain with Central Utah Public Health Department⁴. Utah’s State Construction Code applies to new construction and qualifying repairs, alterations and changes of use in Juab County; current editions include the 2024 International Building Code, 2021 International Residential Code and 2023 National Electrical Code, with applicable amendments^14,15. A building used entirely for agriculture can be exempt from county building permitting, but another use or power requires a permit and inspection¹. The state agricultural exemption does not cover a dwelling; plumbing, electrical and mechanical permits may still be required². Unless another exemption applies, the state exemption is unavailable below 5 contiguous acres inside a city or town or below 2 contiguous acres in a county-approved subdivision; those acreage restrictions do not apply in an agricultural protection area².

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 days⁵.

Juab County has local zoning administered by Planning and Zoning for unincorporated land; use the county Land Use Code and zoning map to identify the parcel’s district³. Mona and Rocky Ridge have their own zoning; Santaquin, which reaches into Juab County, also administers its own zoning^16,17,18. Central Utah Public Health Department remains the septic authority for Juab County addresses⁴. Planning Commission minutes identify 50-acre and 160-acre housing requirements in different A1 districts; confirm the current codified requirement with Planning and Zoning^3,19. One internal accessory dwelling unit within a primary dwelling is permitted in an area zoned primarily for residential use, subject to building, health and fire codes and the local controls Utah law allows¹¹. We could not confirm current minimum dwelling size, setbacks, lot coverage or height limits; ask Planning and Zoning for the parcel’s district standards³.

Central Utah Public Health Department is the septic authority for Juab County^4,6. 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 fee⁶. The listed permit fees are $600 for a conventional system, $900 for an alternative system and $200 for repair or replacement⁶. The installed system must be inspected before it is backfilled⁷. Only 17% of county soils are rated “not limited” for a conventional drain field, so make septic feasibility an early purchase contingency rather than assuming a standard system will work²⁰.

We could not confirm whether unincorporated Juab County allows residential RV occupancy, temporary private-land camping or tiny-home occupancy; ask Planning and Zoning before buying or moving onto the land³. Utah’s RV-park sanitation rule covers RVs and qualifying tiny houses in RV parks, so it does not establish permission to live in one on a private parcel²¹. A manufactured home in Juab County may not be excluded where a single-family residence is permitted, but needs a code-compliant permanent foundation and must meet applicable land-use rules, building codes and restrictive covenants⁸. Manufactured-home additions, garages, carports and storage buildings also must comply with the applicable building code⁸.

1. call Juab County Planning and Zoning to confirm jurisdiction, zoning, allowed use, dimensional standards and the building-permit submittal for the parcel³.

1. secure culinary water. Unincorporated-county projects generally need county-approved culinary water before the building permit, although a signed release can allow earlier permit issuance; occupancy still waits until county and state water requirements are satisfied²². A private well also requires a valid water right and a state Start Card before construction¹⁰.

1. obtain the onsite wastewater construction permit from Central Utah Public Health Department before septic work begins^6,23.

1. resolve driveway access: county roads follow Juab County spacing standards, while a new connection to a state highway requires a UDOT conditional access permit^24,25.

1. obtain the county building permit, complete required inspections, and do not occupy the structure until final inspection and issuance of the certificate of occupancy^1,5.

Water comes first in this dry county: annual precipitation averages 11.7 inches, and severe drought has occurred in 37.9% of years²⁰. A private well needs a valid water right and a Start Card, and unincorporated-county projects cannot receive occupancy approval until county and state water requirements are satisfied^10,22. Septic feasibility also deserves an early site review because only 17% of soils are rated “not limited” for a conventional drain field²⁰. If land will be divided, expect county feasibility review of water, wastewater, drainage, floodplain conditions and soil testing for the proposed lots³. Confirm legal access and driveway geometry because the county limits access to county roads, while state-highway connections require separate UDOT approval^24,25.
