An Ohio container home is a house first: it needs zoning that allows it, a design that meets the Residential Code of Ohio, a foundation designed for the site and a delivery route the truck can use.
A house of one, two or three dwelling units falls under the Residential Code of Ohio. The Board of Building Standards bases that code on the 2018 International Residential Code with Ohio changes, according to its commentary on the code's first chapter. Where a certified residential building department has jurisdiction, the owner applies to its residential building official and obtains approval before work starts. Where none has jurisdiction, section 101.5 of the code says the owner is not required to submit construction documents, seek approvals, request inspections or obtain a certificate of occupancy under that chapter.
Other buildings, such as offices, shops and larger residential buildings, fall under the 2024 Ohio Building Code, based on the 2021 International Building Code. Its Section 3115 covers intermodal shipping containers repurposed as buildings or structures. It asks for construction documents that establish the container's steel and floor properties, and it requires the container to bear its existing data plate, verified by an approved agency.
Ask before removing the data plate. A container's data plate identifies the unit and its ratings, and Section 3115 of the Ohio Building Code relies on it. The section allows the plate to be removed only where the building official approves.
A container home finished in a factory and shipped with its walls closed can count as an industrialized unit. The Board's commentary explains that construction documents for every one-, two- and three-family industrialized unit go to the Board for review and approval, because closed construction cannot be inspected on site. Once an industrialized unit is legally placed the first time, the building code regulates it like any other structure.
Zoning decides whether a dwelling or an accessory structure may stand on the parcel at all, where it may sit and what it may look like. Columbus, Cleveland and Toledo show how different the answers can be.
Outside the cities, the village, township or county that covers the parcel sets the zoning where it has adopted any.
A container carries its load through four corner castings. A home needs a foundation and anchoring that a qualified designer specifies for the actual soil, frost depth, snow and wind. For buildings under the Ohio Building Code, Section 3115 requires a container used as a permanent building to sit on foundations or other supports designed under the code, anchored to them as necessary to provide a continuous load path. Confirm the frost depth for your address with the local building department or your designer rather than copying one from another county.
In the county table of the 2018 International Energy Conservation Code, Ohio is Climate Zone 5A except for nine southern counties in Zone 4A. Ohio adopted that code for homes with state amendments, effective July 1, 2019, according to the U.S. Department of Energy's Ohio status page. Cold winters and humid summers both push moisture toward the steel. The walls and roof need continuous insulation and air sealing, and every cut for a window or a door needs structural and water details.
Container One arranges every delivery and publishes no fixed delivery window. According to its FAQ, the truck needs 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. On a wooded lot in the southeast hills or a narrow city parcel, the delivery plan can set the size of the house.
