Full Breakdown
Will County's Swimming Pool and Spa Code (§ 150.190) defines a residential swimming pool as any pool capable of holding 24 inches of water, triggering the code's requirements. The county's Building Fee Schedule (§ 158.02) sets a $175 permit fee for an above-ground swimming pool, hot tub, spa or similar structure, versus $300 for an in-ground pool. Under the zoning ordinance (§ 155-10.10(E)), accessory pools need a five-foot perimeter barrier and must sit at least ten feet from septic tanks/fields, five feet from side/rear lot lines and eight feet from the nearest building. These rules govern unincorporated Will County only; Joliet, Bolingbrook, Romeoville, Plainfield and Lockport enforce their own separate building and zoning codes.
