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.

ADUs are secondary homes on a single-family lot that provide independent living facilities. You might consider an ADU if you want to increase your property value or provide housing for family. These units are versatile and can be detached or attached to the main house. Exact pricing confirmed free on the call.
