Springfield, OH Accessory Structures: Shed & Carport Rules (2026)

Section 1107.04 of the Springfield Zoning Code sets the general standards that apply to all accessory features, subject to any applicable supplemental standards and all standards applicable to the associated principal use. On size, § 1107.04(a)(3) caps the floor area of any detached accessory building at 50% of the floor area of the principal structure, and the combined floor area of all buildings on the lot still shall not exceed the maximum lot coverage for the zoning district. On height, § 1107.04(d) limits accessory features to a maximum height of 15 feet unless exempted from the height requirements in the Zoning Code.

On placement, § 1107.04(e) requires accessory features to be located on the same lot as the principal use or building, bars location within platted or recorded easements, and sets minimum setbacks: accessory buildings shall be set back at least five feet from any side and 10 feet from any rear property line, plus at least five feet from the principal use or building on all sides. A special rule in § 1107.04(e)(5) tightens the side setback for a detached accessory building sited close to the front of a residence-district lot: one placed closer to the front line than 80 feet must stay no closer to any of its side lot lines than ten feet, and on a corner lot it cannot sit closer than ten feet to the rear line or 20 feet to the street line.

Section 1107.04(c) bars building or using the shed before the principal structure's construction begins and is complete, and § 1107.04(f) requires an accessory building attached to the main building by anything other than an open breezeway to meet the full main-building code.
