Orland Park, IL Accessory Structures: Shed Rules (2026)

Orland Park's zoning and building codes regulate accessory structures including sheds. A building permit is required for any accessory structure greater than 100 square feet in area or with structural or electrical work. Smaller sheds (under 100 sq ft) are exempt from the building permit but still must comply with zoning location and setback rules. Sheds must be located in the rear yard only, not in side or front yards. Typical rear and side setback is 3 to 5 feet from property lines, though specific zones may vary. Sheds must not exceed the maximum accessory structure height specified in the zoning code (generally one story and around 15 feet). Total lot coverage including the principal dwelling and all accessory structures may not exceed zoning district maximums. Electrical service to a shed requires a permit and a licensed electrician. Sheds must be anchored to prevent wind damage and maintained in good condition. Prefabricated plastic and metal sheds are permitted alongside traditional wood construction. HOA architectural review committees in many Orland Park subdivisions impose strict standards on shed materials, color, and placement, often requiring approval before installation.
