Do I need a permit for swimming pool or spa in Naperville?
Yes. In Illinois, swimming pool or spa generally requires a permit, and Naperville is no exception.
In-ground and permanent above-ground pools require a permit in most Illinois jurisdictions. The often-quoted exemption for prefabricated pools less than 24 inches deep comes from the model residential code, not from Illinois law, so confirm the depth and pool type your jurisdiction actually exempts. Most local codes mandate a compliant safety barrier and electrical bonding before the pool can be used. Naperville requires a permit for any pool, hot tub, or spa capable of containing more than 24 inches of water, including in-ground, above-ground, and on-ground pools. A kiddie pool holding 24 inches or less does not need a permit. The pool must be surrounded by a barrier that complies with the International Swimming Pool and Spa Code as adopted and amended by the City. Above-ground pools 24 to 48 inches deep need fencing, gates, and hardware, while pools deeper than 48 inches may use a removable or retractable ladder instead of a fence, and spas may use a locking safety cover. Pool wiring must be done by a state-licensed electrical contractor registered with the City. Confirm current barrier and equipment requirements with the TED Business Group before installation.
