Building permits in Naperville, Illinois: what they show and who they help

Naperville issues building permits citywide, on both the DuPage and Will County sides of the city. Each permit is a public record of work someone has decided to pay for, which makes the permit list a lead source for contractors in that trade and the ones that follow it.

Where Naperville's permit records come from

The city publishes permits on a public EnerGov self-service site. Our Naperville pages cover the Will County part of the city.

For each permit, the public rows we show carry: trade, permit type, month, job value (rounded), status, contractor.
