Commercial Building Permit in Unincorporated Millard County, Utah

Required for new commercial construction in unincorporated Millard County, regulated by the statewide-adopted 2024 IBC (Utah Code § 15A-2-103(1)(a), effective July 1, 2026). Millard County Building Department (Building Official Adam Richins) does not publish a distinct commercial building permit page, application form, or valuation-based fee schedule separate from the general process documented on this file's Residential Building Permit entry — an exhaustive search of the county website, all linked Building Forms PDFs, and the county's 2026 Adopted Budget found no published, dedicated commercial fee schedule, mirroring the same finding already documented for residential permits in this file.

Fee schedule

Building Permit FeeThis mirrors the identical finding already documented on this file's Residential Building Permit entry: 'No published, dedicated valuation-based fee schedule for the primary Residential Building Permit ... could be located despite exhausting the county website, all linked building-department PDFs, the county's 2026 Adopted Budget and Department Expenditures summary, and web/targeted search.' The same conclusion applies to commercial construction — only flat fees for demolition and electrical/mechanical/plumbing/stucco permits are published countywide. Contact the Building Official (435-864-1400) directly for a project-specific commercial fee quote.
Not published — no dedicated commercial or general valuation-based fee schedule was located on millardcounty.gov, in any linked Building Forms PDF, or in the county's 2026 Adopted Budget as of 2026-07-19
Demolition Permit (as reference point for county-published flat fees)Millard County Demolition Application/Permit form (millardcounty.gov) — same flat fee applies to demolition of commercial or residential structures; listed for reference only.
$25.00 + 1% state surcharge ($0.25) = $25.25 total
Electrical Permit (Commercial or Pivot)Millard County Building Permit Application — Electrical/Mechanical/Plumbing/Stucco form; the county's published fee schedule distinguishes a higher 'Commercial or Pivot' electrical rate ($75) from the residential rate ($45), documented on this file's Electrical/Mechanical/Plumbing/Stucco Permit entry — this is the ONE place the county's published fees do split by commercial vs. residential use.

Tips

  • Millard County Building Department does not publish a dedicated commercial fee schedule online — this was confirmed by an exhaustive search of the county website, all linked Building Forms PDFs, and the county's 2026 Adopted Budget, mirroring the identical gap already documented for the county's Residential Building Permit. Call the Building Official (435-864-1400) directly for a project-specific commercial fee estimate.
  • The county's published fee schedule DOES distinguish a commercial rate from residential for one specific permit type — the standalone Electrical Permit ($75 commercial/pivot vs. $45 residential) — suggesting the county is capable of publishing commercial-specific rates but has simply not done so for the core Building Permit Fee.
  • Millard County Building Department also performs Delta City's building inspections under a 2020 interlocal arrangement — a commercial project in Delta may be reviewed by the same county staff; Fillmore City is NOT covered and continues to use Sunrise Engineering.

Unincorporated Millard County, Utah has adopted: 2021 International Residential Code (IRC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(b); unchanged by the July 1, 2026 statewide update. Millard County Building Inspection Department page (adopted codes list) also lists 2021 IRC — live-checked 2026-07-16, page unchanged since last check.; 2024 International Building Code (IBC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(a), effective since July 1, 2026, superseding the 2021 IBC. NOTE (2026-07-16, live-checked): the Millard County Building Inspection Department page still lists 2021 IBC — the county page is lagging the statewide statutory update by 15+ days; the statute is controlling.; 2024 International Plumbing Code (IPC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(d), effective since July 1, 2026, superseding the 2021 IPC. NOTE (2026-07-16, live-checked): the county page still lists 2021 IPC — page lag, statute controls.; 2024 International Mechanical Code (IMC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(e), effective since July 1, 2026, superseding the 2021 IMC. NOTE (2026-07-16, live-checked): the county page still lists 2021 IMC — page lag, statute controls.; 2023 National Electrical Code (NEC) per Utah Code § 15A-2-103(1)(g), statewide in force and NOT changed by the July 1, 2026 update — NOTE: this is a separate, pre-existing discrepancy: Millard County's own Building Inspection page lists 2020 NEC (live-checked again 2026-07-16, page still shows 2020 NEC, unrelated to the 2021→2024 code-edition transition affecting the other codes below). Contractors/homeowners should confirm current applicability with the Building Official as the county page lags the statewide amendment.; 2024 International Fuel Gas Code (IFGC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(f), effective since July 1, 2026, superseding the 2021 IFGC. NOTE (2026-07-16, live-checked): the county page still lists 2021 IFGC — page lag, statute controls.; 2024 International Energy Conservation Code (IECC), Residential & Commercial — per Utah Code § 15A-2-103(1)(h), effective since July 1, 2026, superseding the 2021 IECC. The statute adopts a single IECC edition with no residential/commercial split (this file's existing single combined line already reflects that — no split to collapse). NOTE (2026-07-16, live-checked): the county page still lists 2021 IECC — page lag, statute controls.; 2024 International Existing Building Code (IEBC) — per Utah Code § 15A-2-103(1)(i), effective since July 1, 2026. Not separately listed on the Millard County Building Inspection Department page (live-checked 2026-07-16, page has no IEBC entry at all) — added here because § 15A-2-103 adopts it statewide regardless of the county page's omission.; 2024 residential provisions of the International Swimming Pool and Spa Code (ISPSC) — per Utah Code § 15A-2-103(1)(n), effective since July 1, 2026. Not separately listed on the Millard County Building Inspection Department page (live-checked 2026-07-16, page has no ISPSC entry at all) — added here because § 15A-2-103 adopts it statewide regardless of the county page's omission.; Utah Wildland Urban Interface Code; NOTE (updated 2026-07-16): The July 1, 2026 statewide code-edition transition (2024 IBC/IPC/IMC/IFGC/IECC replacing 2021 editions, per Utah Code § 15A-2-103 version effective 7/1/2026, superseded 1/1/2027) took effect 15 days ago; the next statute version's editions were diffed and confirmed identical, so this should not go stale again around 1/1/2027. 2021 IRC is unchanged by this transition. The International Fire Code is NOT adopted by § 15A-2-103 (it is addressed separately in Title 15A Chapter 5) and is not otherwise referenced in this file..
