Maximum building height is set by your city, village, or township zoning district, not by Hamilton County. Colerain Township caps residential accessory buildings at 15 feet and forbids them exceeding the height of the main house.
Height limits for houses and accessory structures are a local zoning matter statewide. Townships adopt them under ORC 519.02, which lets trustees regulate the "height, bulk, number of stories, and size of buildings." Hamilton County sets no countywide height cap on incorporated land. Colerain Township limits residential accessory buildings to a maximum building height of 15 feet and prohibits any accessory building from exceeding the height of the primary building. Anderson Township likewise caps accessory buildings at 15 feet / 1.5 stories. Principal-structure height maxima are set in each district's regulations, so verify your zone locally.
Exceeding the district height limit results in denial of the zoning certificate and a possible order to modify or remove the excess, or to seek a variance, enforced locally.
