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

The final cost of your ADU is influenced by factors like utility trenching, site excavation, and the complexity of the architectural design. Larger units or those requiring extensive foundation work will naturally cost more than simple interior conversions or small studios. We help you prioritize your budget items to get the most value out of your square footage. Exact pricing confirmed free on the call.
