Commercial Tenant Improvement / Tenant Finish Permit in Milliken, Colorado

Required for tenant finish/tenant improvement work in existing commercial buildings in Milliken. The Town publishes a dedicated 'Commercial Permit Submissions (Tenant Finish)' submittal checklist (ProCode/SAFEbuilt) distinct from the new-commercial checklist, but tenant finishes share the same 'Commercial Permits' review tier (14-21 business days from full submittal) and the same Commercial/Industrial fee structure — the distinction is in submittal requirements, not a separate fee or timeline.

Tips

  • Tenant finish is a distinct published submittal track (its own ProCode/SAFEbuilt checklist with an architect-stamped code study and ComCheck requirement) but NOT a separately priced or separately timed permit — it shares the Commercial Permits 14-21 business day window and the Commercial/Industrial 65% plan review rate.
  • If the tenant finish includes a commercial kitchen, the Town publishes a separate additional Commercial Kitchen Submittal Checklist.
  • Planning Approval may be required before the building permit can be issued — confirm zoning/use compatibility with Community Development early, especially for a change of use (the Fee Schedule lists a $500 'Change of Use Review (Commercial w/no building alterations)' under the Land Use Code chapter).
  • Whether the per-square-foot commercial capital improvement fees (Public Facilities, Police Infrastructure, General Administration at $0.10/sq ft each) and street/drainage fees apply to a tenant finish within an existing shell — versus only to new construction — is not spelled out in the published Fee Schedule; confirm with the Building Department when budgeting a TI.
