Ohio's regulatory framework for detached accessory dwelling units is primarily dictated by local municipal zoning ordinances, as statewide mandates are less common. These local codes are critical and typically specify requirements for lot coverage, setback distances from property lines and the primary dwelling, minimum and maximum ADU dimensions, and utility service provisions. Homeowners must meticulously review their specific municipality's zoning regulations to ensure their proposed ADU design is compliant. The prevailing housing stock in Ohio consists predominantly of single-family residences, many of which possess the lot dimensions and existing infrastructure necessary for the addition of a detached ADU.
