Residential Building Permit in Unincorporated Juab County, Utah

Tips

• Unincorporated Juab County land is served by the Juab County Planning and Zoning Department (160 N Main St, Office #117, Nephi) — this is a separate program from Nephi City's own Building Department, even though Nephi contracts with the county for planning-review services on land-use applications. If your parcel is inside Nephi city limits, you must use Nephi's own Building Permit process (see nephi.json), not the county's.
• Permits become null and void if work is not commenced within 180 days of issuance, or if construction is suspended/abandoned for 180 days at any time after work begins — printed directly on the Juab County Building Permit Application.
• By Utah Code § 17-36-55(3)(a), the county must complete plan review of a one-to-two-family dwelling within 14 business days of a complete application; if the county misses that window, the applicant may formally request completion and the county must then finish within a further statutory window, or (per § 17-36-55(4)) the county may not enforce the plan-review requirement at all if a licensed architect or structural engineer has stamped the plans.
• Acreage-based lots may require a recorded 'Pledge for Building Permit' — the pledged property is then restricted from being used again for acreage determination on any future permit application. Confirm with the Zoning Administrator whether your parcel needs this pledge before applying.
• Owner/builders must file the Utah DOPL Owner/Builder Certification with the county Building Department, which forwards it to the state; owner/builders are limited to one residential structure per year and no more than three in five years under the Utah Construction Trades Licensing Act.

• No published flat-fee or percentage-of-valuation table exists for Juab County building permits — the department calculates the fee from project valuation at time of review. Contact the Planning and Zoning Department at (435) 623-3400 for a pre-application fee estimate.
• Solar PV installations fall under this same permit — the Juab County Building Permit Application form's 'Type of Construction' section offers 'Electrical' as a checkbox alongside 'Residential,' but the county does not publish a distinct solar-specific fee, document requirement, or process separate from the general building permit described here.
• EV charger / EVSE installation would fall under this same permit — the Juab County Building Permit Application form's 'Type of Construction' section offers 'Electrical' as a checkbox, but the county publishes no distinct EV/EVSE-specific fee, checklist, or process (full-text review of the application form and juabcounty.gov/business/building-permits/, checked 2026-07-20, found no 'EV,' 'electric vehicle,' or 'charging station' entry) — the fee would be computed the same as the rest of the Building Permit Fee, from project valuation at time of review.
