1. Home Equity Loans: Use the equity in your existing home to finance your ADU project. This option typically offers lower interest rates and favorable terms.

5. Government Programs and Grants: Look for local and state programs that offer financial incentives or grants for building ADUs. In California, there are specific programs aimed at increasing the availability of ADUs.
6. Personal Loans: Unsecured personal loans can be used for ADU construction, though they may come with higher interest rates compared to secured loans.
