Ohio building code treats above-ground pools like other residential pools: any pool holding water must have a compliant 48-inch barrier, and openings may not pass a 4-inch sphere. Hamilton County sets no separate above-ground rule; your city or township building department issues permits and enforces the state code.
The Ohio Building Code applies barrier requirements to any swimming pool, hot tub, or spa capable of holding water, which includes above-ground pools. The pool wall itself may serve as part of the barrier if it meets the 48-inch height, and ladders or steps must be removable, lockable, or otherwise secured. Permitting thresholds (often based on pool depth or capacity) are set by your local municipal or township building department, not by Hamilton County. Confirm setback and permit rules locally before installing an above-ground pool.
Installing an above-ground pool without required barriers or local approval is a code violation; the building department may require correction, secured access, or removal before use.
