Codes adopted

Utah adopts construction codes statewide under Utah Code Title 15A (State Construction and Fire Codes Act), enforced by every jurisdiction. Chapter 4 of Title 15A codifies Legislature-enacted amendments for specific named jurisdictions (e.g., Park City, Salt Lake City, Sandy City) as part of the state construction code. Through June 30, 2026, the editions in force under Utah Code § 15A-2-103 are the 2021 IBC (with Appendices C and J), 2021 IRC, 2021 IPC, 2021 IMC, 2021 IFGC, 2021 IECC, 2021 IEBC, and 2021 ISPSC (residential provisions), together with the 2023 NEC. Effective July 1, 2026, § 15A-2-103 adopts the 2024 editions of the IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC; the IRC remains the 2021 edition and the NEC remains the 2023 edition. Note: residential energy requirements are modified by statewide amendments, and several Utah jurisdictions document their residential energy provisions at the 2015 IECC level rather than the adopted IECC year — confirm the applicable residential energy code with your local jurisdiction. Always confirm the edition in force with your local jurisdiction.

• 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.
• 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: the Millard County Building Inspection Department page still lists 2021 IBC — the county page lags the statewide statutory update; 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: 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: 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… Show full textShow less

  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 (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: 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. NOTE: the county's own page still lists the 2021 IECC — page lag; the 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 (which has no IEBC entry at all) — included 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 (which has no ISPSC entry at all) — included here because § 15A-2-103 adopts it statewide regardless of the county page's omission.
• Utah Wildland Urban Interface Code
• NOTE: 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) is in effect, and the statute version taking effect 1/1/2027 carries identical code editions. The 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).

Permit types & fees

• Residential Building Permit

  Required for new residential construction, additions, and structural alterations in unincorporated Millard County. Millard County Building Department (Building Official Adam Richins) issues permits for the unincorporated county and, per a 2020 interlocal arrangement, performs building inspections for Delta City (Delta City Council voted to hire the county for inspections in March 2020, ending its contract with Sunrise Engineering). Fillmore City is NOT covered — Fillmore continues to contract with Sunrise Engineering as of the sources checked.

  From$25.00valuation-based→

• Electrical / Mechanical / Plumbing / Stucco Permit

  Required for electrical, mechanical, plumbing, and stucco work in unincorporated Millard County, per the county's combined Electrical/Mechanical/Plumbing/Stucco permit application form. EV charger/EVSE installation is electrical work and falls under this general Electrical permit line; Millard County's permit application form does not publish a separate EV-specific fee item.

  From$45.00→

• Demolition Permit

  Required for demolition of any structure in unincorporated Millard County. Homeowner-performed demolition is regulated by the county (not State Air Quality, which only regulates contractors) for asbestos determination purposes.

  From$25.00→

• Commercial Building Permit

  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 used for the Residential Building Permit — no published, dedicated commercial fee schedule appears on the county website, in any linked Building Forms PDF, or in the county's 2026 Adopted Budget, the same situation as for residential permits.

• Commercial Tenant Improvement / Tenant Finish Permit

  Required for tenant improvement and tenant finish work in existing commercial buildings in unincorporated Millard County. No dedicated tenant-improvement permit type, application, checklist, or fee is published by Millard County Building Department — an exhaustive search of the county website and all linked Building Forms PDFs found no tenant-improvement-specific materials, consistent with the same gap documented for the county's Commercial Building Permit entry.

• Permitted Use Permit (P-1 / P-2) — Change or Establishment of Land Use

  Millard County requires a Permitted Use Permit before a use may be established or changed on a property in unincorporated Millard County — including changing a building's occupancy/use without new construction (e.g., a use that differs from the property's prior permitted use). Per the P-1 application form itself: 'Only when the county planner/zoning administrator has approved the permitted P-1 use... and a building permit issued, as required, may any building, activity, construction, or occupancy be commenced.' Reviewed under Millard County Code Title 10, Chapter 8. Uses permitted outright in a zoning district go through the lower-tier P-1 process (reviewed administratively by the County Planner/Zoning Administrator); uses requiring more scrutiny go through the P-2 Conditional Use Permit process. This is a zoning-authority use-permitting mechanism, distinct from and required in addition to any building permit.

• Sign Permit (P-1/P-2/C-1 depending on sign type)

  Required for signs in unincorporated Millard County under Millard County Code Title 10, Chapter 9 (Sign Standards); the full text of MCC 10-9-1 through 10-9-21 is available via the county's amlegal.com code library. Table 10-9-2 (Allowed Signs) shows the P-1/administrator process does NOT cover the most common commercial sign types — freestanding pylon and monument signs are Conditional C-1 signs decided by the Commission, and wall signs are Permitted P-2 signs also decided by the Commission; only canopy signs go through the P-1/county-planner process. Small on-premises signs, freestanding directional signs, and temporary signs (≤64 sq ft, ≤12 months) require no land use authority approval at all.

  From$85.00→

• EV Charger / EVSE Permit

  Millard County does not publish a distinct EV charger, EVSE, or electric vehicle charging station permit or fee. EV charger/EVSE installation is electrical work and falls under the county's combined Electrical/Mechanical/Plumbing/Stucco permit application, at the $45 residential (or $75 commercial/pivot) Electrical line item. The county's permit application form does not publish a separate EV-specific fee item.

  From$45.00→

• Solar / Solar PV Installation Permit

  Millard County does not publish a distinct residential or commercial rooftop/building-mounted solar or solar photovoltaic (PV) installation permit, application, or fee. Neither the county's Building Inspection Department page, its Forms page, nor the county's combined Electrical/Mechanical/Plumbing/Stucco building permit application carries a separate solar-specific line item — rooftop/building-mounted solar PV installation is electrical work and is billed under the same general Electrical Permit line item used for all other electrical work ($45.00 residential, $75.00 commercial/pivot), the identical pattern as the EV Charger/EVSE Permit. This entry covers customer-sited (rooftop or ground-mount, building-connected) solar PV installation only — it is distinct from the large-scale utility solar generation facilities sited in Millard County (e.g., ECG Utah Solar 1, Pavant Solar), which go through the county's separate land-use/zoning Conditional Use Permit process for major solar energy generation facilities, not the building permit process.

  From$45.00→

• Fire Sprinkler / Fire Alarm System Plan Review Permit

  Neither Millard County nor the Millard County Fire District publishes a local fire-code plan-review or permitting process for fire sprinkler or fire alarm systems — Millard County's own official Public Safety page lists no local Fire Marshal or fire-code authority and instead links directly to the Utah State Fire Marshal's Office. The Utah State Fire Marshal (SFM) accepts direct project plan-review submittals statewide via its own Fire Alarm Plan Review Submittal Form and Automatic Fire Sprinkler Plan Submittal Form, at a fee of $0.022 per square foot reviewed with a $75.00 minimum. However, Utah Admin. Code R710-9-8's mandatory statewide plan-review/inspection scope (triggered when no Local Fire Authority completes the review) is written around publicly-owned buildings, public/private schools, colleges/universities, institutional occupancies, and places of assembly — not general private commercial construction — so the rule text does not clearly establish SFM jurisdiction over a private commercial fire-protection system in unincorporated Millard County. This entry documents the SFM statewide process as the best-available real, verifiable fallback and is marked partial confidence because that specific jurisdictional question is not clearly resolved by the published sources.
