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
An ADU unit is simply a secondary dwelling located on the same lot as a primary residence. You might look into an ADU if you need more space for a home office, a gym, or housing for extended family. Exact pricing confirmed free on the call.
