Residential Building Permit in Unincorporated Juab County, Utah

Required for new residential construction, additions, remodels, and structural alterations on land in unincorporated Juab County (outside Nephi and other incorporated municipalities). Issued and reviewed by the Juab County Planning and Zoning Department, which is organizationally and operationally separate from Nephi City's own Building Department — Nephi contracts with the county for planning services on land-use matters but issues and processes its own building permits under a separate competitively-bid contract (RFP No. 22-01); the county's Planning and Zoning Department independently issues and reviews unincorporated-area permits under its own Building Permit Application and Pledge for Building Permit process.

Fee schedule

Building Permit FeeJuab County Building Permit Application (co.juab.ut.us/Files/Bldg Permit Form.pdf, mirrored at juabcounty.gov/wp-content/uploads/2022/07/Bldg-Permit-form.pdf), 'FOR DEPARTMENT USE ONLY' section: 'Total Valuation $___', 'Building Permit Fee $___', '1% State Fee +___', 'Total Fee $___'. No separate flat-fee table, percentage schedule, or per-square-foot rate is published anywhere on juabcounty.gov, in Utah's Public Notice Website (PMN) filings for Juab County, or in any Juab County Commission resolution located after exhaustive search (county fee-schedule search on utah.gov/pmn returned only unrelated Juab High School athletics/program fee schedules and a Salt Lake-area Consolidated Fee Schedule, not a Juab County building fee schedule). The 1% State Fee is set by Utah Code § 15A-1-209 (Uniform Building Standard Act fee) and applies statewide to all building permit fees collected.

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. Owner-builder
  • 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.

Juab County's Planning and Zoning Department does not publish a distinct local-vintage code page; the county building permit application and land use materials reference compliance with 'all County and State Building Laws and Ordinances,' indicating adoption of the statewide-standard edition without a documented local override.; 2021 International Residential Code (IRC), plus Appendix AQ of the 2021 IRC — Utah Code § 15A-2-103(1)(b)/(c); unchanged by the July 1, 2026 revision — still the current edition.; 2024 International Plumbing Code (IPC) — Utah Code § 15A-2-103(1)(d); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Mechanical Code (IMC) — Utah Code § 15A-2-103(1)(e); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Fuel Gas Code (IFGC) — Utah Code § 15A-2-103(1)(f); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Energy Conservation Code (IECC) — Utah Code § 15A-2-103(1)(h); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026); statute has no residential/commercial split — one edition applies to both.; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i). ADDED 2026-07-16: this code was missing entirely from this file's codesAdopted array; it is not listed on Juab County's own building-permit materials, but it is adopted statewide by statute, so it applies here regardless of the county's omission. Current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Swimming Pool and Spa Code (ISPSC), residential provisions — Utah Code § 15A-2-103(1)(n). ADDED 2026-07-16: this code was also missing entirely from this file's codesAdopted array; same statewide-statute basis as the IEBC entry above.; 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); statewide in force, unchanged by the July 1, 2026 revision.; NOTE (verified 2026-07-16 against the live Utah Code § 15A-2-103 text, version headed 'Effective 7/1/2026 / Superseded 1/1/2027'): the 2024 editions of IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC listed above took effect July 1, 2026, replacing the 2021 editions; IRC (2021) and NEC (2023) did not change. The 1/1/2027 version of the statute carries identical editions, so no further flip is expected then. This file previously forecast this change but still led with the 2021 editions as current, and omitted IEBC/ISPSC entirely — corrected on this date.. Local amendments apply — see the Unincorporated Juab County overview page for the full list.
