Tips

  • Unlike Roy City's and Santaquin's tiered sprinkler permit fees, Box Elder County's Fire Sprinkler System Permit is a flat $300.00 regardless of square footage tier — only the plan review step is tiered by size, and that step carries no county fee (just a required third-party review cost).
  • Budget separately for the third-party plan reviewer's own fee, which is not set by the county and not published in this fee schedule.
