When you need this permit
- Application must give description of project and square footage, total project valuation and electrical valuation, use of surrounding spaces, type of construction, and occupancy group
- Architectural Plans (including floor plan, wall section details, building section, fire-rating details, and code summary), Structural Plans (required for structural changes such as removal of bearing walls, openings in bearing walls, or floor systems for storage), Electrical Plans (required for adding circuits, service upgrades, or emergency lighting, with load calculations, one-line diagrams, and fault current analysis), and Mechanical/Plumbing Plans (required for HVAC equipment changes/relocation/ductwork or refrigeration piping changes, and for any changes to sewers, drains, vents, water piping, roof drains, or gas piping) must each be stamped by a Colorado-licensed architect or engineer, per the Town's dedicated Commercial Tenant Finish Plan checklist
- Documentation showing compliance with the 2024 IECC (energy code) is a listed submittal item on the Town's dedicated Commercial Tenant Finish Plan checklist
- Restaurants and commercial kitchens have the same additional requirements as new commercial construction: grease interceptor, sprinkler system for liquor-serving space over 5,000 sq ft, Type I/II hoods, occupant-load-based exiting, health department approval before CO, and a seating plan — see the Town's Commercial Permit - Checklist
- The applicant will be contacted by SAFEbuilt for any additional information needed to complete plan review; the approved plan set must remain on the job site throughout construction, including final inspections
- No separate Town of Windsor contractor license is required, but licensed design professionals and installing trade contractors must hold current Colorado (DORA) credentials where applicable Contractor
- Windsor-Severance Fire Rescue (WSFR) impact fees, for permits received on or after June 26, 2026, are collected directly by WSFR and due within 30 days of permit issuance, per the Town's general building-permit impact-fee rule
- Whether a specific tenant-finish/change-of-use project separately triggers the Town's Road Impact Fee (as new commercial construction does) was not confirmed in any document reviewed — the Fee Schedule's Road Impact Fee table does not specify whether it applies only to new building square footage or also to a change of tenant/use within existing space; confirm applicability with the Planning/Engineering Department for a specific project rather than assuming either way

Tips
- The Town publishes a dedicated 'Commercial Tenant Finish Plan - Checklist' distinct from the general new-commercial checklist — it explicitly lists 2024 IECC energy-code compliance documentation as a required submittal item, which is not spelled out the same way in the general new-commercial checklist section of the combined Commercial Permit - Checklist PDF.
- The Commercial/Industrial Tenant Finish & Remodel Fee Estimate form must be completed separately for each individual building — if a project spans multiple buildings or suites, budget time for multiple fee-estimate submissions.
- Restaurant/commercial-kitchen tenant finishes (a common Windsor TI scenario) carry the same grease-interceptor, hood-type, exiting, and health-department-approval requirements as new restaurant construction — plan for Weld or Larimer County health department coordination before the Certificate of Occupancy will be issued.
- It was not possible to confirm from any Town document reviewed whether the Road Impact Fee (charged on new commercial construction, e.g. $11,302.00 per 1,000 sq ft for Retail/Commercial) also applies to a tenant-finish/change-of-use project in existing space — don't assume either way; ask the Planning/Engineering Department directly for your specific project.
