Tips

  • Windsor's Building Division is contracted to SAFEbuilt, but unlike some peer SAFEbuilt-contracted jurisdictions in this corpus, Windsor does NOT require its own separate Town contractor license — only the underlying Colorado state (DORA) trade licenses for electrical/plumbing work. Contractor
  • Windsor straddles both Weld and Larimer counties — confirm which county your specific parcel sits in, though the Town's Building Division and codes apply town-wide regardless of the county line.
  • The 2024 I-Codes became effective January 1, 2026 for all new building plans and master plans — if you have an older master plan from before that date, it will not be accepted for a new project; a new 2024-I-Code-compliant master plan is required.
  • SAFEbuilt calculates the actual building permit fee directly from project valuation; the Town's own Fee Schedule does not publish that underlying table, so budget time to get a written estimate from the Permit Technician or SAFEbuilt before committing to a project timeline.
