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
Financing an ADU involves finding a loan product that uses your home's equity or projected rental income to fund the build. You need this if you don't have the full cash amount upfront. Options include renovation loans, home equity lines of credit, or personal loans. Exact pricing confirmed free on the call.
