Commercial Remodel / Tenant Improvement Permit (Tenant Finish/Improvement, Landlord Work, White Box, Core and Shell, Change in Use) in Silverthorne, Colorado

Required for tenant-finish/tenant-improvement work, landlord work, white-box build-out, core-and-shell work, and change-of-use projects in existing commercial space in Silverthorne. It is a distinct published permit track, separate from new commercial construction: the Town's Permit Process by Project Type page lists 'Commercial Remodels (Tenant Finish/Improvement Landlord Work/White Box/Core and Shell/Change in Use)' on its own. That matters in Silverthorne's outlet-mall and retail commercial base, where tenant turnover and buildout are common. Submittal is lighter than new commercial construction — no site plan, landscape plan, or tree conservation plan — but still requires a stamped code study and stamped floor plans.

Inspection process

  1. 1

    Rough Trades (electrical/plumbing/mechanical, as applicable to scope)

    Before concealment; scope-dependent since TI submittal is not a full new-construction package

  2. 2

    Final Inspection

    The department that reviewed and approved the building permit plans also conducts the final inspections prior to CO/Completion. Building inspection requests go through the SmartGov portal by 4 p.m. the day before the desired inspection, per the Commercial Remodels accordion page. An apparent 4 p.m./5 p.m. discrepancy between the Town's pages reflects a dated, site-wide policy/vendor change, not a permit-type split: the Town's Inspections page states the SmartGov cutoff was 5 p.m. until 8/14/26, when it changed to 4 p.m., alongside a vendor transition to Comprehensive Building Code Services effective 8/17/26 (replacing the Summit County Building Department for Building Code plan review/inspections). The Permit Process accordion pages — including this one — show the post-8/14/26 value (4 p.m.).

Tips

  • Tenant improvement/commercial remodel submittals in Silverthorne are lighter than new commercial construction — no site plan, landscape plan, tree conservation plan, or excise-tax line item — but still require a stamped code study, which is unique to this permit type in the file.
  • This permit track explicitly covers five distinct commercial-remodel scenarios under one application: Tenant Finish/Improvement, Landlord Work, White Box, Core and Shell, and Change in Use — confirm which scenario applies since documentation emphasis (e.g., code study for change-in-use) may differ in practice even though the published checklist is unified.
  • Life-safety/sprinkler permits from Summit Fire & EMS apply to ALL commercial properties undergoing this work, not just large-scope projects — budget for this outside-agency step.
  • MAJOR UPCOMING CHANGE, confirmed live 2026-08-02: the Town is replacing the Summit County Building Department with a third-party vendor, Comprehensive Building Code Services (CBCS, info@cbcscode.com / 303-550-2731), for Building Code plan review and inspections town-wide, effective 8/14/26 (inspection cutoff moves to 4 p.m.) through 8/17/26 (CBCS takes over plan review/inspections generally). Electrical work stays with Summit County per the Town's Plan Review & Revisions page ('ALL Electrical changes go directly to the Summit County Building Department'). This affects every permit type in this record, not just commercial ones — worth a file-wide re-verification pass after 8/17/26.
