How to Finance Your ADU

Building an Accessory Dwelling Unit (ADU) is one of the smartest investments a homeowner can make — but figuring out how to pay for it can feel overwhelming. The good news is that there are more financing options available today than ever before.

1. Cash-Out Refinancing

If you have built up equity in your home, a cash-out refinance lets you replace your existing mortgage with a larger one and take the difference in cash. This often offers the lowest interest rates, since the loan is secured by your primary residence.

2. Home Equity Lines of Credit (HELOC)

A HELOC works like a credit card backed by your home equity. You draw funds as needed during the construction phase and only pay interest on what you use. This flexibility makes it a popular choice for ADU projects.

3. Construction Loans

Construction loans are short-term loans designed specifically for building projects. They typically convert to a permanent mortgage once construction is complete. These loans release funds in stages as construction milestones are met.

4. ADU-Specific Financing Programs

Several lenders now offer loans tailored specifically for ADU construction, recognizing the rental income potential. These programs often consider future rental income when qualifying you for the loan.

5. Government Programs and Grants

Depending on your state, you may qualify for grants or low-interest loans. California, for example, has launched several ADU incentive programs. Check with your local housing authority for opportunities in your area.

Final Thoughts

The right financing option depends on your equity, credit score, income, and long-term goals. We recommend speaking with a financial advisor and comparing offers from multiple lenders before committing.
