Detached accessory dwelling unit — Cleveland, OH
Last updated: September 24, 2026
What affects the price
Building an ADU involves several moving parts that shape your total investment. The final figure depends heavily on whether you choose a prefab unit or a custom build from the ground up. Site conditions are another major factor; if your property requires extensive grading, utility trenching, or foundation work, costs will climb. You also have to consider your choice of finishes, like high-end appliances or custom cabinetry. Navigating local permit fees and impact assessments also adds to the total.
About this service
A detached ADU is a standalone building separate from your main house, like a cottage or a converted garage. You choose this style if you want maximum privacy for your tenants or family members. Because it requires its own foundation and utility lines, it is a significant construction project. Exact pricing confirmed free on the call.
