For Evanston, this guide uses 3 official utility, permitting, or licensing sources plus 2 installer-owned service-area sources; re-check each before contracting.
Evanston’s Building Permits page provides separate links for contractor registration and registration renewal, and tells applicants to check whether a company already has a registration before filing a new one. That lookup step is a practical administrative check for a contractor preparing a city permit submission.
Building PermitsEvanston's dense lots, older roofs, tree shade, and lake weather can determine both system layout and reroofing scope.
Evanston site reviews should evaluate Lake Michigan weather, snow, wind, freeze-thaw cycles, storms, and shade from dense trees or buildings.
ComEd's distributed-generation interconnection process applies to ComEd-served properties.
These primary sources are tied to the local claims above. Re-check them before signing because rules and program terms change.
