Fishers, IN Accessory Structures: Shed Rules (2026)

Sheds are detached accessory structures regulated by Fishers UDO Article 6.2, Accessory Structure Standards. Sec. 6.2.2 covers residential accessory buildings such as garages, gazebos, carports, greenhouses, and similar structures, which includes storage sheds. The combined gross floor area of ALL accessory structures on a residential lot is limited by parcel size: 1,000 sq ft on lots under 1 acre, 1,500 sq ft on 1-2 acres, 2,000 sq ft on lots over 2 but under 4 acres, and 4,000 sq ft on 4-plus-acre lots; the structure also may not exceed the maximum lot coverage of the zone. For placement, the front setback must meet the zone's required front setback, and the side or rear setback must meet the primary-structure setback or 10 feet, whichever is less. Any accessory structure over 600 sq ft must have a setback at least equal to the building's height where that exceeds the minimum side/rear setback. Sheds may not encroach into any easement or required buffer yard and must comply with Article 6.20 Vision Clearance Standards. The maximum height for accessory structures in the R1-R5 and MP districts is 18 feet (24 feet in ER, 22 feet for non-agricultural uses in AG). A building permit is generally required; the UDO's permit exemption (Sec. 6.2.2.D) lists items like playhouses, pergolas, and above-ground pools, but storage sheds are not among the exempt items.
