Tips

  • Box Elder County does not scale down its Commercial Building Permit Submittal checklist for tenant-improvement scope — bring only the items relevant to your project (e.g., skip footing/foundation plans for interior-only work) and confirm with the Building Official which items apply to your specific TI.
  • The 65% commercial plan review fee and $2,500 deposit apply regardless of whether the project is new construction or an interior tenant finish, since the county's fee schedule does not carve out a separate TI rate.
