Retaining walls in Naperville require building permits under Title 5 (Building Regulations). The permit process reviews structural adequacy, drainage impact, and setback compliance. Taller retaining walls may require engineering certification to ensure structural safety. Walls must not interfere with established drainage patterns or stormwater management infrastructure. Retaining walls near property lines must comply with zoning setback requirements. The wall design must account for hydrostatic pressure, soil conditions, and drainage behind the wall. Naperville Township Road District may also require permits for retaining walls in its jurisdiction. All retaining wall construction should be preceded by a JULIE call (1-800-892-0123) at least 48 hours in advance to locate underground utilities.
Retaining wall without permit: stop-work order. Structural failure or drainage issues: mandatory correction at owner expense. Setback violations: zoning enforcement.
