This is PermitBase’s published record for Unincorporated Cache County as of 2026-07-19. It has since been superseded — see the current record. A historical record reflects what PermitBase had verified at that time; it may not capture a real-world change the jurisdiction had made but PermitBase had not yet verified, and it includes any errors we later corrected.

The 1/1/2027 version of the statute carries identical editions, so no further flip is expected then. This file previously forecast this change but still led with the 2021 editions as current — corrected on this date.

Commercial Tenant Improvement / Tenant Finish Permit

Verified

Required for tenant improvement (tenant finish) work in existing commercial buildings in unincorporated Cache County — interior build-outs, remodels, and finish work for a new or changing tenant space. Listed as its own 'Tenant Improvement/Finish' line item in the COMMERCIAL PERMITS section of the county's fee schedule (Ord. 2024-18), distinct from and generally cheaper than the 'New Construction, Addition & Remodel (Commercial)' table. The three lowest valuation tiers are billed as a flat fee with no added plan-review percentage; the schedule switches to a base fee plus 65% plan-review percentage at $500,000+ valuation.
