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.

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 is published. 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 condition-based residential engineering triggers (trusses, 70+ psf snow load, non-prescriptive design). 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 (see Tips & Gotchas).

Yes.
