Swimming Pools & Spas in Naperville, IL: What Residents Actually Need to Know

By CityRuleLookup Editorial Team

If you live in Naperville or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Naperville has 2 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.

Fencing & Safety Requirements

Naperville requires physical barriers around every swimming pool, spa, and hot tub to block unsupervised access and prevent drowning, under its adopted International Swimming Pool and Spa Code amendments.

Key details: Governing code: ISPSC § 305.1, as amended. Enforcing agency: Transportation, Engineering and Development Dept.. Applies to: All aquatic vessels: pools, spas, hot tubs. Adopted model code: 2024 International Swimming Pool and Spa Code.

Building without an approved barrier blocks issuance of an occupancy or final inspection sign-off; the City can order corrections and withhold permit closeout until the barrier meets Section 305.1.

Pool Permits

Naperville adopts the 2024 International Swimming Pool and Spa Code for every aquatic vessel, and a pool permit application is deemed abandoned if not pursued within 180 days of filing.

Key details: Code adopted: 2024 ISPSC. Application abandoned: After 180 days. Extension available: One 30-day extension. Permit expires: 1 year from issuance.

Letting a pool permit application or an issued permit lapse under the 180-day deadlines forces the applicant to restart the process, including new plan-review and administrative fees for reissuance.

The Bottom Line

Naperville's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Naperville is broadly strict or permissive.

All of the above reflects Naperville's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
