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 estimate is a preliminary assessment of what your ADU project might cost before the final design is locked in. It helps you decide if your budget aligns with the size of the unit you want. Costs vary based on whether you choose a detached structure or a garage conversion. It is a starting point for planning. Exact pricing confirmed free on the call.
