Do you need a permit for a pole barn in Ohio?
Ohio has two parallel codes: the Ohio Building Code (OBC) for commercial and multi-family structures, and the Residential Code of Ohio (RCO) for one- and two-family dwellings. Local townships administer their own zoning and may set additional requirements. Ohio Revised Code § 3781.06 explicitly exempts agricultural buildings used exclusively for farm purposes from the state building code. Most pole barns for residential, garage, or commercial use require a permit.
