Commercial Building Permit in Unincorporated Emery County, Utah

Required for new commercial construction on unincorporated land in Emery County. The Building Type & Fee Calculation table on the county's own Building Permit Application lists 'Commercial Building' as its own line item, valued the same per-square-foot valuation mechanism as residential building types (no separate commercial multiplier), with the same 65% Plan Check Fee and 80%-of-1% State Surcharge applied uniformly. Commercial plans must be drawn by a certified architect and/or engineer, per the county's Permit Process page.

Fee schedule

Base Building Permit Fee — Commercial BuildingEmery County Building Permit Application (Building Type & Fee Calculation table) lists 'Commercial Building' as its own row, using the same per-square-foot mechanism (Sq Ft Area x Sq Ft Value) as all other building types on the form. No separate commercial dollar-per-square-foot rate distinct from the form's general ICBO 1997 UBC methodology was independently confirmed in this review — the underlying PDF's fee table is form-field/scanned content that could not be fully machine-verified; treat this fee structure as consistent with, but not pixel-verified against, the residential entry's already-confirmed base fee formula.
Valuation-based, per square foot value assigned to the 'Commercial Building' line on the Building Type & Fee Calculation table, using the ICBO 1997 Uniform Building Code (UBC) valuation/fee schedule

Tips

  • Emery County requires a certified architect and/or engineer stamp on ALL commercial building plans — an unconditional requirement, unlike residential where a stamp is only required for unconventional construction (log, metal frame) per the county's Permit Process page.
  • Inspections are scheduled through Sunrise Engineering (1-800-560-6151, ask for Katrina), which the county contracts for inspection services — a minimum of 24 business hours' notice is required.
  • It is not explicitly published whether Emery County's outside-city-limits 10-acre minimum lot rule and 1000-point Building Permit Point System (both written in residential/dwelling terms) apply to commercial projects — confirm directly with the Zoning Administrator before assuming either does or doesn't apply to a commercial site.
  • For inside-city-limits commercial construction (Castle Dale, Clawson, Cleveland, Elmo, Emery, Ferron, Green River, Huntington, Orangeville), contact the respective city hall — this file covers unincorporated land only.

ADDED 2026-07-16: this code is not listed on Emery County's own building-code pages, but it is adopted statewide by statute, so it applies here regardless of the county page's omission.; Utah Wildland Urban Interface Code — Emery County Building & Zoning; COUNTY-PAGE LAG (live-checked 2026-07-16): the Emery County Building Permit Requirements page (emery.utah.gov/home/department-directory/bz/building-permit/) still lists '2021' for IBC, IPC, IMC, IFGC, IECC, and IEBC (plus '2020' for NEC, noted above) — the page has not been updated for the July 1, 2026 statewide flip to 2024 editions. The 2024 editions and 2023 NEC listed in this array are the legally in-force editions per Utah Code § 15A-2-103, not the county page.; 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, and IEBC listed above took effect July 1, 2026, replacing the 2021 editions; IRC (2021) and NEC (2023, per statute — see county-page discrepancy note above) 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 — corrected on this date.. Local amendments apply — see the Unincorporated Emery County overview page for the full list.

Yes. Per Emery County's Permit Process page, commercial buildings require plans drawn by a certified architect and/or engineer — this is a hard requirement, unlike residential permits where a stamp is only conditionally triggered for unconventional construction types.
