Full Breakdown

A building permit is required for an in-ground pool, and for an above-ground pool deeper than 24 inches, in unincorporated Johnson County and in Iowa City, Coralville, and North Liberty. Plan review covers zoning setbacks, drainage, GFCI-protected electrical, and the barrier. Iowa runs a statewide building code framework under Iowa Code chapter 103A, and the county enforces the 2024 International Residential Code. A final inspection is required before the pool is filled. Iowa's freeze-thaw winters make proper winterizing essential. Public and semipublic pools answer to Iowa Public Health under Iowa Administrative Code 641 chapter 15; a single-family residential pool is expressly excluded.

Violations & Fines

Building a pool without the permit brings a stop-work order and retroactive permitting with penalty fees. Electrical work done without an electrical permit fails inspection.

Frequently Asked Questions

Do I need a permit for a backyard pool?
Yes. In-ground pools and above-ground pools over 24 inches deep need a building permit from Johnson County PDS or your city building department.
Does the state health department inspect my home pool?
No. Iowa's 641 chapter 15 rules cover public and semipublic pools. A pool at a single-family home is excluded and handled through the local building permit.
