Arlington Heights, IL Accessory Structures: Shed Rules (2026)

The Village of Arlington Heights permits accessory storage sheds in rear yards of residential properties. Sheds under 100 square feet in floor area and not exceeding one story do not typically require a building permit, though they must comply with all zoning setback and height requirements. Sheds 100 square feet or larger require a building permit from the Community Development Department. All sheds must maintain a minimum 3-foot setback from rear and side property lines. The maximum height for accessory structures is generally 15 feet. Sheds must be anchored to resist wind uplift. Metal, wood, and vinyl sheds are all permitted, but the structure must be maintained in good condition and complement the character of the neighborhood. Sheds may not be placed in front yards or side yards forward of the front building line. The total lot coverage of all structures (house, garage, shed, patio) must not exceed the maximum lot coverage percentage for the zoning district. Sheds may not be used as habitable space, workshops with permanent utility connections, or for commercial storage. Pre-fabricated sheds must meet the same setback and height requirements as site-built structures.
