Will County and its municipalities require building permits for retaining walls over 4 feet measured from bottom of footing. Walls with surcharge (driveway, slope, structure above) require engineered plans from an Illinois licensed PE regardless of height.
The 2018 IBC/IRC as adopted by Will County and municipalities exempts retaining walls under 4 feet (measured bottom of footing to top) with no surcharge load. Will County LUO §155-15 and Land Use Department require permits for walls over 4 feet, with Illinois PE-stamped drawings showing soil analysis, drainage, geogrid reinforcement if segmental, and factor of safety calculations. Walls with surcharge from structures, driveways, pools, or slopes require engineering regardless of height per IRC R404.4. Joliet, Bolingbrook, Romeoville, and Plainfield each require engineered plans; Plainfield Village Code §9-37 specifically requires PE stamp for walls exceeding 30 inches with surcharge. Drainage provisions (weep holes, drain tile, free-draining backfill) are mandatory. Setbacks typically 3-5 feet from property line; taller walls may require easements. Will County Stormwater Management Ordinance requires no increase in runoff onto neighboring property.
Unpermitted retaining walls: stop-work order, potential demolition if not engineered, retroactive permit fees tripled. Fines under Joliet §4-4 and similar provisions range $200-$1,000 per violation. Stormwater violations: up to $1,000 per day under Will County SMO.
