Commercial Tenant Improvement / Tenant Finish Permit in Unincorporated Iron County, Utah

Required for tenant improvement and remodel work inside an existing commercial building in unincorporated Iron County. Iron County's Fee Schedule does not publish a tenant-improvement-specific line; the county's single 'Remodel' fee line (B.P. Contractor's Estimate, P.C. 40% to 65% + State Fee) is a flat, undifferentiated line applying to any remodel/alteration project regardless of occupancy — unlike new construction, which the same Fee Schedule splits into ten distinct per-square-foot valuation rates by IBC occupancy group. No residential/commercial split, occupancy table, or separate TI-specific line exists anywhere in the document for remodel-type work. (Note: the Fee Schedule PDF's embedded text layer misaligns this exact table when extracted as flowed text, shifting dollar figures onto the wrong row labels — e.g. pairing the 'Finish Basement' label with figures belonging to the 'Remodel'/'Plumbing' rows — so the table should be read from the laid-out pages.) Combined with the $500 Commercial Building Application/Plan Review Submittal Fee (vs. $250 Dwelling), which routes by property/project type per Legend note (d) rather than by new-construction-vs-remodel distinction, this is the operative fee structure for a commercial tenant improvement in unincorporated Iron County.

Fee schedule

Remodel
Iron County Fee Schedule, adopted May 26, 2026, page 2 (Building Department table). Show full citationIron County Fee Schedule, adopted May 26, 2026, page 2 (Building Department table). This section does not copy-paste cleanly — a copy-paste shifts dollar amounts onto adjacent row labels, for example pairing 'Finish Basement' with figures belonging to other rows — so read the figures from the page as published. The line reads: 'Remodel — B.P. Contractor's Estimate, P.C.40% to 65% + State Fee.' This is the only Building Department fee line for remodel or alteration-type work, and it is NOT split by residential vs. commercial or by occupancy classification anywhere in the schedule — unlike new construction, which the same document prices via ten distinct per-square-foot rates by IBC occupancy group (see the commercial-building-permit entry). It is the operative fee mechanism for commercial tenant improvement work by elimination: no other remodel or alteration-type line exists in the document.

Tips

  • Iron County's 'Remodel' fee line (Contractor's Estimate valuation, Plan Check 40-65%) is a single flat line covering ANY remodel/alteration project — residential or commercial — since the Fee Schedule publishes no separate commercial-remodel or tenant-improvement rate. The columns in this table do not line up in a copy-paste, so read the figures from the fee-schedule page as published.
  • The $500 Commercial Building Application/Plan Review Submittal Fee (versus $250 for a Dwelling) applies to commercial permits generally, including tenant improvement work, per the Fee Schedule's Legend note (d): 'Dwelling ($250) Commercial ($500) Other ($50).'
  • No tenant-improvement-specific application form, checklist, or PDF exists on the county's Forms page (ironcountyut.gov/building/forms) as of 2026-08-02 — the standard Building Permit Application and Building Permit Info Sheet ('building-packet.pdf') cover all project types, including remodels, without a distinct commercial-TI variant.

The 1/1/2027 version of the statute carries identical editions, so no further flip is expected then. Iron County's own building.gov/building page and its Forms index (ironcountyut.gov/building/forms) do not republish specific code-edition numbers, so the editions here are the statutory default rather than a county-specific citation — Cedar City, by contrast, does publish its own distinct Current Adopted Codes list.. Local amendments apply — see the Unincorporated Iron County overview page for the full list.
