Naperville Solar, Electrical, and Generator Permit Guide

Naperville requires permits before residential solar panels, generators, and electrical work, with city-specific utility and contractor requirements.

Permit takeaway

Naperville says solar photovoltaic permits must be obtained before installing solar panels, and all generators added to a residential structure require an issued building permit before construction.

Zoning and placement

Solar, generator, and electrical work can raise placement, utility, service, noise, screening, setback, and electrical distribution questions because Naperville operates its own electric utility.

Building and trade review

Naperville requires a permit before any electrical work within city boundaries, and electrical installations must be performed by a state-licensed electrical contractor registered with the city.

Call before applying when

Call before applying if the project includes solar panels, a generator, battery equipment, service work, low-voltage wiring over listed limits, or electrical work tied to another permit.
