Solar Photovoltaic (PV) Permit in Windsor, Colorado
Required for installation of rooftop residential or commercial solar photovoltaic systems within the Town of Windsor. Building permit review and inspection is contracted to SAFEbuilt, the same third party that administers all other Windsor building permits; the electrical portion is governed by the 2023 NEC. No dedicated solar/PV fee line item is published in the Town's Fee Schedule — solar is billed under the same SAFEbuilt valuation-based Building Permit Fee plus the Town's 25% Administration Fee, subject to Colorado's statewide solar permit fee cap.

Tips
- Windsor's building permit fee for solar is calculated by SAFEbuilt (the Town's contracted building-permit administrator) using the same valuation-based structure as any other building permit, plus the Town's 25% Administration Fee — no solar-specific discount or flat fee is published.
- Colorado's statewide solar permit fee cap (C.R.S. § 24-48.5-113) still limits what Windsor can charge in total building-permit fees for a residential solar PV system to $500 ($1,000 commercial), even though the Town's own Fee Schedule has no dedicated solar line item — confirm the cap is being applied if the SAFEbuilt valuation-based fee calculates higher.
