Full Breakdown
Will County's zoning code (§155-10.10(E)) requires every accessory swimming pool to have a perimeter barrier at least five feet high, measured from grade or finished floor, installed per the county building ordinance: a height rule that overrides any other fence or wall limit in the zoning ordinance. In-ground pools must be set back 25 feet from septic tanks/fields (ten feet for above-ground pools), and pools must sit at least eight feet from buildings, five feet from side and rear lot lines, and ten feet from any street lot line. This applies only in unincorporated Will County; Joliet, Bolingbrook, Romeoville, Plainfield and Lockport regulate pools under their own municipal codes.
Violations & Fines
The Zoning Administrator enforces the barrier rule; each week a barrier violation goes uncorrected after notice is a separate offense, pursued through administrative adjudication under County Code Chapter 43.
