Fire Sprinkler / Fire Alarm Permit in Unincorporated Duchesne County, Utah

Duchesne County does not publish a standalone fire-sprinkler or fire-alarm permit, application, or fee schedule. Per the county's own Business License Application guidance ('Applying For A Business License – Building & Fire Codes'), plan review for fire-protection systems is conducted jointly by the Department of Building Safety and the county's own Fire & Emergency Management Department (referred to elsewhere in county materials as the Fire Marshal's Office or Fire Warden) as part of the underlying Commercial Building Permit or Change of Use Building Permit — not as a separate fire-permit type. Utah Code § 53-7-104(2) provides that 'the fire officers of any city or county shall enforce the state fire code and rules of the state fire marshal in their respective areas,' and Duchesne County's Fire & Emergency Management Department is that local fire officer for the county, so the statewide Utah State Fire Marshal's Office submittal/fee process ($0.022/sq ft, $75 minimum, per its own Automatic Fire Sprinkler and Fire Alarm submittal forms) is not confirmed to be the applicable path here — the county appears to review fire-protection systems itself rather than deferring to the state office. This gap in a published standalone fee schedule, combined with the unconfirmed state-vs-county review question, keeps this entry at partial confidence.

Fee schedule

Minimum Fire-Protection Permit Fee (Simple Scope, e.g., Fire Alarm Install)Duchesne County Business License Application, 'Applying For A Business License – Building & Fire Codes': 'if your proposed use is similar to the previous use you may only need to install a fire alarm or something simple like that. This would most likely require a minimum permit fee of $55.55.'
$55.55
Building Permit Fee (Valuation-Based, Extensive Fire-Protection Scope)Same generic valuation methodology documented for the Commercial Building Permit; the county's guidance states 'the permit fee will be based on an estimated construction valuation' for more extensive alterations, and 'for major projects, the permit and associated alterations can be fairly costly.' Not confirmed whether the 35%-65% plan review fee or 1% state surcharge apply on top of this for a fire-protection-only scope.
Calculated from the county-adopted cost-per-square-foot valuation table published in the August issue of the ICC Building Safety Journal

Tips

  • There is no standalone fire-sprinkler or fire-alarm permit fee schedule published by Duchesne County — expect either the $55.55 minimum fee (simple scope, e.g., adding a fire alarm to a like-for-like use) or the full valuation-based Building Permit Fee (extensive fire-protection or life-safety alterations), per the county's own Business License Application guidance.
  • Contact the Duchesne County Fire & Emergency Management Department directly at (435) 738-1226 (mlefler@duchesne.utah.gov or sfelter@duchesne.utah.gov) in addition to the Department of Building Safety, (435) 738-1150, since fire-protection scope is determined by joint review between the two offices.
  • If a fire hydrant is not within 400 feet of a commercial building, the county's guidance says that alone will not block a business license or building permit — an alternative fire-protection method providing an acceptable equal level of protection must be worked out with the Fire Marshal's Office / Fire & Emergency Management Department instead.
  • Do not assume the Utah State Fire Marshal's statewide $0.022/sq ft ($75 minimum) submittal process applies here — Duchesne County's own Fire & Emergency Management Department appears to conduct this review directly as the county's local fire officer under Utah Code § 53-7-104(2), so confirm which office's fee schedule governs before applying.

No. Duchesne County publishes no standalone fire-sprinkler or fire-alarm permit or fee schedule. Fire-protection work is reviewed jointly by the Department of Building Safety and the county's Fire & Emergency Management Department (Fire Marshal's Office) as part of the applicable Commercial Building Permit or Change of Use Building Permit, with a minimum fee of $55.55 for simple scope or a full valuation-based fee for extensive work.

The county's guidance states that all commercial buildings are to have a fire hydrant within 400 feet, but an approved alternative method providing an acceptable equal amount of protection can be used instead if a hydrant isn't present — this does not by itself prevent a business license or building permit from being issued.
