Fremont offers preapproved ADU plans that can help reduce the time, cost, and uncertainty of building an ADU. Applications using these plans require a geotechnical report and a title report, and a historic evaluation may be required for homes built before 1945. The city also lists an ADU Amnesty Program among its permit resources.
