Tips

  • Cache County uses a separate, higher-fee COMMERCIAL PERMITS valuation table from the residential/unincorporated SFD table — do not estimate a commercial project's fee using the residential tiers.
  • Plan review on commercial permits is 65% of the base fee, versus 15% for most residential permit types — budget accordingly.
  • An Application Commercial Plan Review Deposit ($1,000 or $2,500 depending on valuation) is due at submittal, in addition to the eventual permit fee.
  • The Owner/Builder Certification form does not apply to commercial projects per Cache County's Building Permit Applications page — that form is limited to residential new construction, remodels, and additions. Owner-builder
  • Cache County's own guidance flags commercial review as taking materially longer than residential — 30-45 working days versus 3-10 working days — so plan submittal timing accordingly.
  • Call the building office at (435) 755-1650 press 1 to confirm project-specific requirements before submitting.

Unincorporated Cache County, Utah has adopted: 2024 International Building Code (IBC), including Appendices C and J — Utah Code § 15A-2-103(1)(a); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026); 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. NOTE (county page live-checked 2026-07-16): the Cache County Building Code Information page lists 2024 IECC in its main statewide-codes list but separately carries a 'Residential Code: 2021 IRC and the 2021 IECC' line for dwellings up to a duplex — that residential IECC carve-out lags the statute, which adopts a single 2024 IECC edition with no residential/commercial split; the statewide 2024 IECC governs.; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i); 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); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026); 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); statewide in force, unchanged by the July 1, 2026 revision. NOTE: The Cache County Building Code Information page (last seen 2026-06-30) still lists '2020 NEC' — that page is not updated; the statewide 2023 NEC is the legally in-force edition.; 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 — corrected on this date..
