Commercial Building Permit in Unincorporated Kane County, Utah

Required for new commercial construction in unincorporated Kane County, regulated by the statewide-adopted 2024 IBC (Utah Code § 15A-2-103(1)(a), effective July 1, 2026). Kane County Building Department requires engineered, PE-stamped plans for ALL commercial projects (per the county's own engineering-requirement FAQ) — a stricter standard than the state minimum applied to residential work. The county does not publish a separate commercial valuation table distinct from the general Building Permit Fee formula used for residential permits.

Fee schedule

Building Permit Fee (Valuation-Based)Same formula documented on this file's Residential Building Permit entry, sourced from the Kane County Building Department's own permit-application document (dochub.com/fillable-form/103833-kane-county-utah-building-department). Kane County Code § 8-1-3(B) sets fees by County Commission resolution; the 2026 general fee resolution (R 2026-1) confirms Building Department fees are set 'as set by the International Building Code' rather than itemized separately by residential vs. commercial in the county-wide fee schedule. No distinct commercial-only valuation bracket or percentage was found published as of 2026-07-19. Confirm exact current amount with the Building Department at (435) 644-4985 before budgeting.

Tips

  • Kane County requires PE-stamped engineered plans for ALL commercial projects, with no exceptions based on project size or scope — this is stricter than the residential engineering triggers (trusses, 70+ psf snow load, non-prescriptive design) documented elsewhere in this file. Budget for engineering costs and lead time accordingly.
  • No separate commercial valuation-fee table distinct from the general ICC-Current-Valuation-Data-plus-25%-plan-check-fee-plus-1%-state-fee formula was found published — call (435) 644-4985 for a project-specific estimate.
  • Kane County spans extensive wildland-urban interface terrain — a qualifying commercial project in a high-risk WUI area may also need a Fire Hazard Severity Form, Sample Wildfire Mitigation Plan, and the $500 WUI permit fee documented in this file's tipsAndGotchas.

NOTE: the Kane County Building Department webpage (last seen 2026-07-07) still lists '2020 NEC' and '2021 IBC/IPC/IMC' — that page has not been updated to reflect the current statewide codes; the versions listed here are the legally in-force editions per the Utah Legislature's current-version code text.; 2024 International Energy Conservation Code (IECC) — Utah Code § 15A-2-103(1)(h); statewide effective 7/1/2026; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i); statewide effective 7/1/2026; International Wildland-Urban Interface Code (IWUIC) — adopted per Utah Code § 15A-2-103; Kane County actively enforces this with a WUI-specific permit fee, Fire Hazard Severity Form, and Wildfire Mitigation Plan requirement given the county's extensive wildland-adjacent terrain near Zion National Park and Grand Staircase-Escalante National Monument.
