Commercial Building Permit
Required for new commercial construction in unincorporated Duchesne County (plus the Towns of Altamont and Tabiona, which fully contract building-permit review to the county). The Duchesne County Permit Packet does not itemize a distinct commercial fee table or a commercial-specific plan-review percentage separate from residential — re-verified 2026-07-19 by direct full-text extraction of the county's own 14-page Permit Packet, in which the word 'commercial' appears only in the codesAdopted context (IECC commercial provisions) and an unrelated owner-builder certification clause, never in the fee or plan-review sections. The same valuation-based fee methodology, 35%-65% plan review range, and 1% state surcharge documented for the Residential Building Permit apply to commercial projects.

The packet gives this range in a worked residential example only and never uses the word 'commercial' to explain what determines where a project falls in the range — NOT confirmed that the high end specifically applies to commercial. Commercial projects should expect to fall toward the higher end given typically greater plan-review complexity, but this is not stated by the county. |

EV Charger / EVSE Permit
Duchesne County publishes no distinct EV charger / EVSE permit or fee, and no minor-work flat fee at all. The Department of Building Safety's Permit Packet (July 2023) prices every building permit purely by estimated construction cost valuation, with no published minimum fee or standalone electrical-only category — an EV charger installation would need to go through the same valuation-based Building Permit process as any other electrical work, with no smaller flat-fee alternative documented.
