Pool Construction Permits in Naperville

Local Rule

City of Naperville Transportation, Engineering and Development Business Group

The city's own page states plainly that a permit is required for the installation of any swimming pool, above-ground or in-ground, with no small-pool exemption published. Naperville genuinely spans both DuPage and Will counties; DuPage County separately maintains its own Swimming Pool and Spa Code based on the 2021 ISPSC for unincorporated areas, but Naperville itself, as an incorporated city, administers pool permits directly through its own department at 400 S. Eagle Street, (630) 420-6070.
