Shed permit rules in Warren County, OH — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Warren County's Rural Zoning Resolution (Article II, Chapter 3) regulates accessory structures in unincorporated areas. Sheds 200 square feet or smaller require only a Zoning Permit from the County Building & Zoning Department; sheds 201 sq ft or larger need both a Building Permit and a Zoning Permit. Setback distances vary by zoning district. Inside a municipality (Lebanon, Mason, Springboro, etc.), the city's own zoning code controls.
Per the Warren County Rural Zoning Resolution administered by the Warren County Building & Zoning Department, "if the shed is 200 sq ft or less, you will only need a zoning permit. If the shed is 201 sq ft or larger, then you will need to have a building and zoning permit." Any accessory structure must meet the development standards of the applicable zoning district — including setbacks, height limits, lot coverage, and parking requirements. The Rural Zoning Resolution covers unincorporated Warren County (townships such as Deerfield, Hamilton, Turtlecreek, Salem, and Washington). Townships with their own zoning may layer additional rules. Within incorporated municipalities (Lebanon, Mason, Springboro, Franklin, etc.), the city's zoning code applies. Contact Warren County Building & Zoning at 513-695-1290 for the specific setback for your zoning district.
Building a shed over 200 sq ft without a building permit, or any shed without a zoning permit, is a violation of the Rural Zoning Resolution. The County Zoning Inspector can issue stop-work orders and citations. Daily fines and required removal/relocation may follow.
