Tinley Park requires a building and electrical permit for solar photovoltaic installations on homes. Illinois law (765 ILCS 165, the Homeowners' Energy Policy Statement Act) protects the right to install solar and limits HOA restrictions. Permits include structural review for roof loads and electrical review for interconnection compliance.
Tinley Park permits rooftop solar photovoltaic (PV) systems and generally ground-mount systems on residential property with a building permit. Permit application requires plans showing panel layout, roof attachment method, structural calculations demonstrating the roof can support the system plus snow and wind loads, and electrical single-line diagrams showing inverters, disconnects, and interconnection. Licensed electrical contractor installation is required for the electrical portion. The utility (ComEd) requires an interconnection agreement for grid-tied systems; net metering is available under Illinois law. Fire setbacks on the roof (typically 3-foot pathways at ridge and along edges for rooftop access per the International Residential Code) are required. Ground-mount systems require setback compliance similar to other accessory structures and may not exceed height limits. Illinois's Homeowners' Energy Policy Statement Act (765 ILCS 165) limits HOA authority to prohibit solar; HOAs may impose reasonable aesthetic restrictions but cannot effectively ban solar or increase costs more than 10%. Illinois Shines and federal tax credits provide significant financial incentives.
Unpermitted solar installations may result in stop-work orders and required re-inspection with structural and electrical compliance documentation. Safety and fire code violations are prioritized. Code Enforcement: (708) 444-5100.
