Commercial Building Permit (New Construction / Addition or Alteration) in Rathdrum, Idaho

Required for new commercial construction (allowed in Zones C1, C2, I, HI) and for additions or alterations to an existing commercial structure (adding commercial space, siding, roofing, windows, or demo work) within Rathdrum city limits. The City publishes two separate checklists for these scopes — Commercial New Construction Permit Checklist and Commercial Addition or Alteration Permit Checklist — but both use the same Building Permit Application and BS&A Online submission process, distinguished only by the permit-type selection ('Commercial' vs. 'Com - Addition or Alteration'). Reviewed against the City's locally-adopted 2018 IBC plus City Design Criteria.

Tips

  • Rathdrum publishes two distinct commercial building checklists — Commercial New Construction and Commercial Addition or Alteration — but both route through the same BS&A Online Building Permit Application; select 'Commercial' or 'Com - Addition or Alteration' at the Enter Permit Details step.
  • Commercial plan review (65% of permit cost) is billed at a materially higher rate than residential plan review (25% of permit cost) under the same Master Fee Schedule.
  • The per-square-foot construction cost used in the fee formula varies significantly by occupancy group — e.g., B Business at $209.02/sq ft vs. S-1 Storage at $86.03/sq ft — so the same building footprint can produce very different permit fees depending on use.
  • New commercial construction is limited to Zones C1, C2, I, and HI; confirm zoning before assuming a parcel qualifies.
  • No published review-timeline figure exists for Rathdrum commercial building permits — confirm current turnaround directly with the Building Department, (208) 687-7242, before planning a project schedule.
