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
Turning an ADU into a rental means creating a separate, functional living space on your property to generate monthly income. This is a practical choice if you want to offset your mortgage or capitalize on high housing demand in your area. You will need to account for local zoning rules and utility metering. Exact pricing confirmed free on the call.
