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

Storage sheds in Oak Park are regulated as accessory structures under the zoning ordinance. Sheds must be located in the rear yard and comply with setback requirements from property lines (typically 3 feet from side and rear property lines). Sheds under approximately 100 square feet in floor area and under a certain height may be exempt from a building permit, but they still must comply with zoning setback and lot coverage requirements. Sheds over the exempt threshold require a building permit. All sheds count toward the maximum lot coverage allowed in the zoning district. Prefabricated and site-built sheds are subject to the same rules. Sheds may not be used as habitable space. Electrical service to a shed requires an electrical permit. The shed must be constructed of durable materials and maintained in good condition. Sheds that fall into disrepair may be cited as property maintenance violations. The maximum height for accessory structures is generally limited to one story. Metal, wood, and vinyl sheds are all generally permitted provided they meet building code standards.
