Tips
- Casper issues no separate solar-PV permit type; rooftop PV is permitted as a combined building + electrical permit under the general valuation-based fee schedule (City of Casper Fee Schedule, eff. Feb 2, 2026) — confirm the exact submittal path directly with the Building Inspection Division at (307) 235-8254 before applying.
- Structural calculations should account for Casper's snow and wind load design criteria under the 2024 IRC/IBC.
- The electrical portion is inspected by Casper's own Building Inspection Division (not the WY State Fire Marshal), consistent with Casper's local electrical authority.
Frequently asked questions
- Does Casper have a specific solar permit process?
- Casper does not publish a standalone solar PV permit type or fee schedule. Solar installations are processed through the standard building permit (for racking/structural work) and electrical permit (for wiring/interconnection) processes, both issued by the City's Building Inspection Division and priced off the combined valuation-based fee table.
