How homeowners pay for an ADU

Four ways to fund the build. One of them usually fits.

Most families do not write a check for the whole project. They borrow against the home they already own, and the ADU adds value that supports the loan. Here is the plain-language version of each option; the lender will walk you through the fine print.

Most common

Home equity loan or HELOC

Borrow against the equity in your home. A home equity loan gives you a lump sum at a fixed rate; a HELOC is a line you draw on as the build progresses. Your first mortgage stays untouched.

Best for homeowners with meaningful equity and a low existing mortgage rate they want to keep.

One loan, one payment

Cash-out refinance

Replace your current mortgage with a larger one and take the difference in cash to fund the ADU. Simple to manage, and the new payment can be offset by rental income.

Makes sense when current rates are close to your existing rate, or when you want to consolidate.

Built for building

Construction or renovation loan

A loan sized to the finished value of your property with the ADU, released in draws as construction milestones are met.

Best when existing equity is limited but the finished project will appraise well.

Mix and match

Savings plus a smaller loan

Many families fund part of the build from savings or a family contribution and borrow the rest. A smaller loan means faster approval and a lighter monthly payment.

Common for Family Integrity Planning projects where a parent or adult child is contributing.

Loan programs, rates, and terms are set by the lender and depend on your property, income, and credit. Acton ADU makes the introduction and supports the lender's process; the lender handles qualification and approval.

Does it pay off?

Think in three buckets, not one monthly number.

Homeowners often start by asking what the ADU will rent for. Our savviest clients look at the whole picture, and rent is the smallest piece of it.

Same square footage, not the same value

Two 500-square-foot ADUs are not built equal, and they are not worth the same either.

It is no different than two homes of the same size on the same street selling for very different prices. Design, quality, and craftsmanship are the difference, and they are what an appraiser and a renter both pay for. That is why quality is an investment, not a cost, when the goal is long-term value.

Completed Acton ADU, San Jose

1

Day-one equity

A well-designed, traditionally built ADU is often appraised at a similar price per square foot as the main home. Appraisals on our completed projects consistently show homeowners adding more value than they invested.

2

Wealth that compounds

Once the value is added, the ADU appreciates with the rest of the property. Ten or fifteen years out, that can mean hundreds of thousands of dollars in additional family wealth.

3

Monthly cash flow

Rent helps carry the loan. So does the money a family does not spend on a care facility or a second rent check.

Equity and appreciation outcomes are illustrative and vary by property, design, city, and market. Talk with an appraiser or financial advisor about your own numbers.

What happens after you submit

Three steps. No obligation at any of them.

Questions homeowners ask

ADU financing FAQ

Do I need to own my home outright?

No. Most homeowners who build an ADU still have a mortgage. What matters is the equity you have built and the value the finished ADU adds, which is how home equity loans, HELOCs, and renovation loans are sized.

What credit score do I need?

It depends on the lender and the program. We work with multiple lending partners with flexible credit requirements, so submit the form and we will match you with the one whose requirements fit your situation.

Which loan is right for me?

That is what the introduction is for. Tell us how you are thinking about paying for the project and we will connect you with the lending partner whose programs fit. They will walk you through the options for your property and finances.

How long does funding take?

It depends on the loan type and the lender. Our partners offer fast approvals and closings, and we time the introduction so funding lines up with your design and permit schedule.

Can I finance a Build Ready ADU?

Yes. Build Ready plans come with complete drawings, engineering, and a defined scope, which makes them straightforward for lenders to appraise and fund.

What does Acton charge for this?

Nothing. Connecting you with a lending partner is part of helping you get the project built.
