Fee schedule

Building Permit Fee (Valuation-Based)Sourced from Kane County Building Department's own permit-application document. The county's live website (kane.utah.gov) no longer directly links this legacy PDF — it was superseded by the Utah CityInspect online-only portal — but its exact fee-structure language is preserved via a third-party document host (dochub.com/fillable-form/103833-kane-county-utah-building-department) that mirrors the original county-authored form verbatim, and is independently corroborated by multiple search-indexed citations of the same text. County Commission sets fees by resolution per Kane County Code § 8-1-3(B); the 2026 general fee resolution (R 2026-1) confirms the Building Department's fees are set 'as set by the International Building Code' rather than itemized in the county-wide schedule, consistent with this valuation-based structure. Confirm exact current amount with the Building Department at (435) 644-4985 before budgeting a project.

Tips

  • Kane County no longer accepts paper building permit applications — all submissions and inspection requests go through the Utah CityInspect portal (utah.cityinspect.com).
  • Utah Code § 17-36-55(3)(a) sets a 14-business-day statutory floor for a county to complete plan review of a one-to-two-family dwelling or townhome once a complete application is submitted; if the county misses this deadline, the applicant may request completion and the county must then finish within 14 additional days. Kane County's own materials do not publish a separate, shorter SLA, so this statutory timeline is the governing verified figure.
  • A building permit application that does not meet the completeness requirements of Utah Code § 17-36-55(8)(a)-(g) (site plan, construction drawings, energy compliance documentation, structural calculations, contact information, etc.) will be rejected outright rather than reviewed.
  • New single-family homes require a $1,500 refundable construction bond, returned only after final occupancy is issued.
  • Kane County requires engineered, PE-stamped plans for a wide range of conditions beyond the state minimum — call (435) 644-4985 to confirm whether your project needs engineering before applying.
  • Building permits are valid for 180 days from issuance; construction must begin within that window or the permit expires (Kane County Code § 8-1-3).
  • Kane County spans significant wildland-urban interface terrain near Zion National Park and Grand Staircase-Escalante National Monument — the county actively enforces the International Wildland-Urban Interface Code with its own $500/$300 WUI permit fee, Fire Hazard Severity Form, and Sample Wildfire Mitigation Plan for projects in high-risk areas.
  • Solar panel installation falls under this same permit — the Kane County Building Department FAQ (kane.utah.gov/faq.aspx?TID=17) lists 'Solar panel install' alongside water heater replacement, meter base installation, and electrical panel replacement as projects requiring a permit, but the county publishes no distinct solar-specific fee or process; the county's 2026 Schedule of Fees resolution (R 2026-1) is a scanned document without a machine-readable text layer, so a distinct solar fee line, if one exists, could not be confirmed.
  • EV charger / EVSE installation is not listed on the Kane County Building Department FAQ (kane.utah.gov/faq.aspx?TID=17) or Building Department page (both re-checked 2026-07-20, no 'EV,' 'electric vehicle,' or 'charging station' entry found) — the FAQ lists 'meter base installation' and 'electrical panel replacement' among projects requiring a permit, so a standalone EV charging circuit would be expected to require the same valuation-based Building Permit Fee (ICC Current Valuation Data + 25% plan check fee) as other electrical work; as with solar, the county's scanned 2026 Schedule of Fees resolution (R 2026-1) could not be checked for a distinct EV fee line.

Local amendments apply — see the Unincorporated Kane County overview page for the full list.
