Do I need a permit for solar panel installation in Wheaton?
Yes. In Illinois, solar panel installation generally requires a permit, and Wheaton 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. Wheaton provides a dedicated Solar Panel Installations guideline and requires a permit before installing a residential photovoltaic system, covering both the structural mounting and the electrical work. A grid-connected system must meet the adopted 2023 National Electrical Code as amended by Wheaton, and the interconnection is handled through ComEd, the local utility. The electrical work must be performed by a contractor registered with the City of Wheaton. Confirm the current solar submittal requirements with the Building and Code Department at 630-260-2050 before finalizing a design.
