Commercial Tenant Improvement / Tenant Finish Permit in Nephi, Utah

Required for tenant improvement and tenant finish work in existing commercial buildings in Nephi. Nephi does not publish a distinct tenant-improvement application, checklist, or fee tier separate from its general Commercial Building Permit process — tenant improvement projects are processed as commercial construction using the same Building Permit Application, Commercial Permit Plan Check Fee, and valuation-based Building Permit Fee.

Tips

  • Nephi treats tenant improvement/tenant finish work as ordinary commercial construction for permitting and fee purposes — there is no separate TI application or discounted plan-check fee tier published as of 2026-07-19. Confirm scope-specific requirements directly with the Building Department (435-250-8086, building.permit@nephi.utah.gov) before applying.
  • The same $600 minimum Commercial Permit Plan Check Fee that applies to new commercial construction also applies to tenant improvement projects — there is no reduced rate for remodel-scope work in Nephi's published fee schedule.

The current statewide edition is the 2023 NEC per Utah Code § 15A-2-103(1)(g), unchanged by the July 1, 2026 statewide update (a prior version of this entry incorrectly stated '2020 NEC' as if that were a specific city-documented edition; Nephi's own document does not name a year at all).
