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 prefab ADU is built in a factory and then transported to your property for final assembly. You might choose this if you want a faster construction timeline and less mess in your backyard compared to a traditional build. Because the structure is made off-site, it often helps with site control and weather-related delays. Exact pricing confirmed free on the call.
