Des Plaines requires building and electrical permits for solar photovoltaic installations on residential and commercial properties. Permits are issued by the Department of Community and Economic Development. Illinois's Homeowners' Solar Rights Act (765 ILCS 165) limits homeowner association restrictions on residential solar installations.
Solar PV installations in Des Plaines require both building and electrical permits. The application typically includes a site plan showing panel layout, structural calculations confirming the roof can support the additional load, electrical line diagrams showing inverter and disconnect locations, and equipment specifications. Roof-mounted systems on single-family homes generally do not require a zoning special use, but ground-mounted systems are subject to setback and lot coverage rules for accessory structures. All electrical work must be performed by a licensed electrician with proper grounding, AC and DC disconnects, and labeling per the National Electrical Code. ComEd interconnection approval is required to connect the system to the grid through net metering. Inspections include a rough-in (mounting and conduit), electrical, and final inspection. Illinois's Homeowners' Solar Rights Act (765 ILCS 165), enacted in 2011 and amended thereafter, restricts the ability of homeowner associations to prohibit residential solar installations, though reasonable aesthetic restrictions remain permitted. Illinois Shines (the Adjustable Block Program) provides solar renewable energy credit incentives.
Installing solar without permits may result in a stop-work order, double permit fees, and required removal of unpermitted work. Des Plaines Building Division at (847) 391-5380 enforces. Unpermitted work may also void homeowner insurance and Illinois Shines incentive eligibility.
