Fee schedule
| Fee type | Amount | Notes |
|---|---|---|
| Commercial Building Permit Fee — valuation-based (same schedule as new commercial construction) | $30.18 minimum (valuation up to $800), scaling per the Commercial Building Permit Fees Valuation Table | City of Idaho Falls Fee Schedule (October 2025), item 2.7 — no separate tenant-improvement-specific valuation table exists; TI/remodel permits are billed on the same commercial valuation table as new construction |
| Commercial Plan Check Fee | 65% of the permit valuation | City of Idaho Falls Fee Schedule (October 2025), item 2.8.b — same rate applies to remodel/TI as to new commercial construction |
| Permit Issuance Fee | $30.18 | City of Idaho Falls Fee Schedule (October 2025), item 2.13.a |
| Fire Department Structural Plan Review Fee | 16% of Building Permit Valuation | City of Idaho Falls Fee Schedule (October 2025), item 3.1.g — applies where the Fire Department conducts structural plan review; the checklist for this permit type explicitly calls out fire alarm and fire sprinkler system documentation, suggesting Fire Department review is commonly triggered for TI/remodel work, but the Fee Schedule does not itemize exact trigger criteria |
