Do I need a permit for solar panel installation in Arlington Heights?
Yes. In Illinois, solar panel installation generally requires a permit, and Arlington Heights is no exception.
Most Illinois jurisdictions require both a building and an electrical permit for rooftop or ground-mount solar, plus a separate utility interconnection approval. Many local codes require roof structural verification and fire-access setbacks. Those requirements come from the code edition your municipality or county has adopted, not from a statewide Illinois residential code. Arlington Heights requires a Solar Panel Systems (Residential) permit before installation, and rooftop systems generally involve both a building review and a separate electrical permit filed through the Civic Access Portal. The electrical work must be performed by a state-licensed electrical contractor. State-licensed electricians, plumbers, and fire alarm contractors are exempt from the Village's separate contractor registration, but they must still hold the required state license. The Village adopts and amends the ICC codes, and a grid-connected system will also need to meet ComEd's interconnection rules.
