Full Breakdown
The City's Table 14A-12-1204.2 splits residential-scale solar installs into two tiers under the Chicago Construction Codes. Systems under 13.44 kW, with or without up to 20 kWh of battery storage, need no construction drawings but do require a zoning-fee review and cost a flat $225 permit fee. Arrays at or above 13.44 kW skip the storage allowance, must submit drawings, still require zoning review, and are billed $250 per array with a $1,000 minimum. Both tiers are issued as a stand-alone electrical permit through the Department of Buildings rather than a full building permit.
Violations & Fines
Installing solar panels without the required permit is a Construction Codes violation, exposing the owner or installer to a $500 to $1,000 fine plus a possible stop-work order.
