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
Obtaining an ADU permit is the legal process of getting city approval for your secondary structure. You need this documentation before any construction begins to ensure your build meets local safety and zoning codes. The permitting phase can involve architectural plans and engineering reviews. Fees and design costs for this stage typically add several thousand dollars to your project. Exact pricing confirmed free on the call.
