Use a Home Equity Line of Credit to Build Your ADU — With Maximum Flexibility

 

Want to build an ADU without touching your first mortgage? A HELOC (Home Equity Line of Credit) gives California homeowners a flexible, interest-only way to fund their ADU — with no refinance and no large upfront payments.

It’s a smart way to access your equity on your terms.

What Is a HELOC?

 

A HELOC is a revolving credit line that allows you to borrow against the equity in your home, similar to a credit card — but with far lower rates and higher limits.

You can:

  • Draw funds as needed (pay-as-you-go)

  • Only pay interest on the amount you use

  • Reuse it again later, if approved

Perfect for phased ADU construction, unpredictable timelines, or when you want lower payments during the build.

Why Choose a HELOC for Your ADU?

 

Here’s why homeowners in California love using HELOCs for their ADU:

  • No need to refinance your 1st mortgage

  • Draw only what you need, when you need it

  • Interest-only payments during the draw period

  • Re-use your line of credit for other projects

  • W-2, self-employed, and asset-based borrowers welcome

HELOCs are all about control and flexibility — especially if your ADU build is staged.


Who Qualifies for a HELOC?

 

HELOCs are widely accessible. You’ll typically need:

  • Property in California (SFR or up to 4 units)

  • At least 15–20% home equity

  • Credit score of 660+

  • Verifiable income (W-2, bank statements, or assets)

How Much Can I Borrow?

 

Your HELOC limit depends on:

  • Home value

  • Mortgage balance

  • Credit and income

Many ADU homeowners get $50,000–$250,000+, with interest-only payments during the draw phase and flexible repayment afterward.
