Solar PV Permit in Evanston, Wyoming
VerifiedSolar systems in Evanston require BOTH a City of Evanston building permit AND a Wyoming State Plan Review and Electrical Permit — a dual local/state review confirmed directly in the City's own Building Permit Legal Requirements ('Solar Systems require a building permit and a Wyoming State Plan Review and Electrical Permit'). This matches W.S. § 35-9-108's state plan-review trigger for 'alternate energy generation installation feeding to the utility' and the WSFM chart's state electrical classification for Evanston.

Tips
- Do not assume the City permit covers the electrical interconnection — a separate State of Wyoming Plan Review AND Electrical Permit are both required for solar in Evanston.
- Alternate energy generation feeding the utility is one of the explicit state plan-review triggers under W.S. § 35-9-108, independent of building size.
