In Ohio, a shipping container raises two separate questions: what the state building code requires, and what local zoning allows at the address. Columbus, Cleveland and Toledo answer the zoning question in three different ways.
The Ohio Board of Building Standards adopts the state's building codes, based on the International model codes, and local building departments that meet the Board's certification requirements enforce them. Zoning is a separate, local question, answered by the city, village, township or county that zones the address. Townships and counties can adopt zoning for unincorporated land under sections 519.02 and 303.02 of the Ohio Revised Code. A container can clear one review and still need the other, so the first step is to find both offices for your parcel.
Columbus lists shipping containers among the items that may not be left in a residential yard. Cleveland allows a permitted container on residential property for a limited time and up to 20 feet long. Toledo asks for a Certificate of Zoning Compliance for every residential accessory building, and its guidance does not mention containers.
The Residential Code of Ohio covers one-, two- and three-family dwellings and any accessory structure that goes with the house, according to the Board's commentary on the code's first chapter. Section 102.10 of that code lists work exempt from approval, including a one-story detached accessory structure used as a tool and storage shed, a playhouse or a similar use, provided the floor area does not exceed two hundred square feet.
A 20ft container covers about 160 square feet and a 40ft about 320, so only the smaller box is under that size. The local building official decides whether a steel container counts as a storage shed. The exemption covers building approval only, and zoning still applies.
The Ohio Building Code covers buildings other than one-, two- and three-family homes. Its current edition took effect on March 1, 2024, based on the 2021 International Building Code, as the City of Toledo explained when it summarized the Board's update. That code has a section for intermodal shipping containers, Section 3115, which applies to containers "repurposed for use as buildings or structures, or as a part of buildings or structures."
Section 3115 asks for construction documents that establish the dimensions and the physical properties of the container's steel and floor. It also requires the container to bear its existing data plate, verified by an approved agency, with a report of the findings for the owner. The plate may come off only where the building official approves its removal, so if a container might become an office, a workshop or part of a building, leave the plate in place until you have that approval.
Plans for these buildings go to the certified local building department or, where none is certified, to the superintendent of the state's Division of Industrial Compliance, as the Board's commentary quotes from the Revised Code.
The Board's rules do not apply to buildings or structures incident to the agricultural use of the land they sit on, provided they are not used in the business of retail trade. According to the Board's commentary, when a township zoning inspector issues a zoning certificate declaring a building is to be used in agriculture, the building is exempt. Ask the township zoning office how a container on your farm will be classified before it arrives.
Columbus City Code section 3332.289 says that no person in a residentially zoned district shall store or leave certain items in a yard outside a completely enclosed building or structure. The list includes a "motor vehicle as defined by Ohio Revised Code Section 4511.01, airplane, boat, shipping container, or trailer except as provided for by Chapter 3312, Off-Street Parking and Loading." Section 3303.19 defines a shipping container as a standardized cargo container, usually made of steel, designed and built for intermodal freight transport.
The city's portable storage allowance in section 3390.02 covers a temporary structure less than 169 square feet in size and eight feet in height. It allows one on a parcel for two non-sequential periods of up to 14 days each per calendar year, and it does not permit one as a permanent accessory storage structure. A standard shipping container stands 8 ft 6 in tall.
Columbus is also moving parts of the city to a new zoning code, Title 34, through its Zone In program. The Title 34 definition of an accessory use says it does not include storage or shipping containers. For any Columbus parcel, call Building and Zoning Services at (614) 645-7433 before you order. A container placed in a street or other public right-of-way needs the Department of Public Service's permission through its Right-of-Way Permit Office.
Cleveland Codified Ordinances section 337.231 treats a movable container used for temporary storage on residential property as a portable storage container and sets these rules:
The size limit means a 20ft container is the largest that fits a Cleveland residential lot under this section. Business and industrial sites follow their district zoning. The Department of Building and Housing is at 601 Lakeside Avenue, (216) 664-2282. Its Division of Construction Permitting has taken applications only in digital form, through the city's permit portal, since April 13, 2026.
Toledo's guidance on garages and sheds says every residential accessory building needs a Certificate of Zoning Compliance, and one larger than 200 square feet also needs a building permit and plan review. The same page allows two accessory buildings per lot, sets them at least 60 feet from the front property line and 3 feet from side and rear lines, and says business may not be conducted from a residential accessory structure. The page does not mention containers, so ask the Toledo-Lucas County Plan Commission, at (419) 245-1200, how a container at your address is classified.
For larger projects, Toledo Municipal Code section 1109.0502 lists shipping containers among the prohibited building materials on facades visible from the right-of-way. That standard covers multi-dwellings, commercial, mixed use and institutional buildings, and large-scale retail projects. Building permits go through the Division of Building Inspection at (419) 245-1220.
The city in a mailing address is not always the government that zones the parcel. Dublin, Lakewood and Perrysburg sit next to Columbus, Cleveland and Toledo with governments of their own. Ask the zoning office of the city or village in your address whether the parcel is inside its limits. If it is not, ask the township office whether the township or the county zones it.
Container One arranges every delivery. Its FAQ asks for 110 feet of straight, unobstructed space for a 20ft container and 130 feet for a 40ft, at least 15 feet of height to drive, 22 feet of height along the entire unloading path and 10 feet of width. It publishes no fixed delivery window, because timing depends on the location, when payment is received, the weather and other factors.
