Top Ways to Finance Your SoCal ADU

Most homeowners don’t pay for an ADU entirely in cash. Instead, they use smart, strategic financing options that look at either your current home equity or the future value of your home once the ADU is completed.

1. Renovation Construction Loans (RenoFi & Custom Products)

This is often the best option for homeowners who haven’t accumulated decades of equity yet. Specialized renovation loans allow you to borrow against the Future Completed Value of your property (your current home value + the projected value the ADU adds).

• The Benefit: Allows you to secure significantly more funding upfront at lower, primary-mortgage interest rates, without forcing you to refinance your existing low-rate first mortgage.

2. Home Equity Line of Credit (HELOC)

A HELOC acts like a revolving credit line secured by the equity you’ve already built in your primary home.

• The Benefit: You only draw and pay interest on funds as construction milestones are met (e.g., foundation pour, framing, finishes). This keeps your initial monthly payments lower during the build phase.

3. Cash-Out Refinance

With a cash-out refinance, you replace your current primary mortgage with a new, larger loan, taking the difference out in a lump sum of cash to fund your ADU construction.

• The Benefit: Gives you a fixed interest rate and blends your home mortgage and ADU construction costs into a single, predictable monthly payment.

4. Direct Construction-to-Permanent Loans

Ideal for large detached builds or second-story ADUs. This loan pays out in structured “draws” to us (your contractor) during the construction process. Once the city signs off on your final inspection, the loan automatically converts into a standard, long-term traditional mortgage.
