Fee schedule

Building Permit Fee (both commercial and residential; applies to tenant improvements)Re-chased 2026-07-23 by downloading Ordinance 834-P directly and rendering page 33 to an image (the source PDF is scanned/non-machine-readable). Item 2, 'Building Permit Fees (both commercial and residential),' sets a flat 0.0075 rate with no carve-out for alterations/tenant-improvement work, and this file's Bid Contract document requirement exists specifically to establish a project's construction valuation for fee purposes. The County's posted 'Building Valuation Data – FEBRUARY 2026' (ICC BVD) document separately notes the BVD table itself 'is not intended to apply to alterations or repairs to existing buildings' — so for a tenant improvement, the 'construction valuation' the 0.0075 rate is applied against is based on the submitted Bid Contract cost rather than the ICC BVD square-footage table (which only prices new whole structures). Contact the Building Department at (435) 336-3124 or buildingquestions@summitcountyutah.gov to confirm the exact valuation figure that will be used for a specific project before applying.

Plan Review Deposit (tenant improvement / 'all other permits')Summit County Building Department Fee Schedule, Ordinance 834-P, item 12.b: 'Plan Review Deposit (commercial, residential and agricultural) — All other permits: $65 deposit...' — this $65 tier (vs. the $200 new-structure tier at item 12.a) applies to tenant improvement/remodel permits since they are not new structures. Read directly from the ordinance PDF (page 34, rendered to an image), 2026-07-23.

Inspection process

  1. 1

    Framing / Rough-In (MEP)

    After framing and rough-in mechanical, electrical, and plumbing work — before insulation or wall cover; only applies to the extent the scope of work includes these items

  2. 2

    Weather Barrier

    Only applicable if the scope of work includes redoing the exterior; windows must be installed and all exterior wall penetrations completed prior to this inspection

  3. 3

    Fire District Inspection

    If applicable to the scope of work, the local fire district should complete its inspection prior to the building department's final. Scheduled directly with the applicable fire district, not through EPROCESS360.

  4. 4

    Final

    All work complete; space approved for occupancy under the tenant's use classification. An approved final inspection does not by itself constitute a Certificate of Occupancy.

Tips

  • A Utah-licensed architect is only required for tenant improvements of a finished shell and change-of-use remodels — the County's checklist does not require an architect for every tenant improvement, unlike its blanket architect requirement for new commercial construction.
  • A Site Plan is only required if the exterior is being redone or there is a change of use — many pure interior tenant finish projects can skip this document, per the County's Commercial Remodel/Tenant Improvement Checklist.
  • A Construction Mitigation Plan (per Summit County Code § 7-7-11) is only required if exterior work is proposed as part of the tenant improvement scope.
  • Re-chased 2026-07-23: the Building Permit Fee rate applying to tenant improvements IS published — Ordinance 834-P item 2's flat 0.0075-of-valuation, $100-minimum rate is not limited to new construction, and a $65 Plan Review Deposit (item 12.b, vs. $200 for new structures) applies. The construction valuation itself is based on the submitted Bid Contract cost rather than the ICC BVD square-footage table, since the BVD methodology explicitly excludes alterations. Contact the Building Department at (435) 336-3124 for a project-specific estimate.
  • All submissions, reviews, and issuance are processed exclusively through the EPROCESS360 online portal (summit.co.ut.eprocess360.com) — the County does not accept paper plans or perform over-the-counter reviews.

Frequently asked questions

Only if the project is a tenant improvement of a finished shell or a change-of-use remodel — the County's checklist requires those specific project types to be designed by a Utah-licensed architect. Other tenant improvements do not carry a blanket architect requirement in the checklist.

The same 0.0075 (3/4 of 1%) Building Permit Fee rate that applies to new residential and commercial construction (Ordinance 834-P, item 2) also applies to tenant improvements, $100 minimum, plus a $65 Plan Review Deposit (item 12.b) and the 1% state surcharge. Because tenant improvements are alterations rather than new structures, the construction valuation the rate is applied to comes from the submitted Bid Contract cost rather than the ICC Building Valuation Data table. Contact the Building Department at (435) 336-3124 for a project-specific total.

The County's Commercial Remodel/Tenant Improvement Checklist (current as of June 2026) states estimated review times are 21-26 business days — the same range published for new commercial construction. This is a County-published estimate, not a guarantee.
