The Ultimate Guide to Financing Your ADU with Studio Home

An ADU is a major home project. You do not need to wait until you have the full cost in cash, but you do need a financing plan that reflects the full scope of the build. The question is not simply, “Can I get a loan?” It’s, “Can I fund this project on terms that still work for my household?”

Create a Complete ADU Project Budget Before You Finance

Our Design Center can give you a configuration as a solid starting point, which matters when you are deciding what to finance. Things like foundation, shipping and assembly are items to consider beyond the ADU itself. Permitting, utility connections, inspections and HOA requirements can also change the total. Those costs are not side notes: they can determine whether a financing amount is enough to complete the work without redirecting cash from other priorities.

Our process turns an early configuration into a more usable project plan through site review, design coordination, permit and construction documents, production, delivery and installation. Local plan review can take four to 12 weeks, depending on the jurisdiction, which is why a preliminary design is more useful than a guess at a loan amount.

Choose an ADU Loan Your Household Budget Can Support

A lender assesses the property, your debt, your income, your credit history and other underwriting criteria. Your own test should be tighter: does the payment still feel manageable after your current mortgage, living costs, insurance, taxes, existing debt and ordinary surprises?

A HELOC is an open-end line of credit that lets you borrow repeatedly against home equity. Keep in mind: the home secures the line, so if you cannot make the required payments, you could potentially lose the home. That does not rule out a HELOC, it just means the payment should make sense within your budget before you rely on projected ADU income, a future raise or an unusually good month.

Before you apply, ask three questions. How much equity is available after the first mortgage and lender limits? What will the payment be under the quoted terms? Would the payment work during a vacancy or before a lender confirms how it treats expected rental income?

Studio Home and Figure HELOC Financing for ADUs

We have partnered with Figure to offer eligible homeowners a HELOC path for a backyard project. An online rate check begins with a soft credit pull, digital closing options in supported states and funding in as few as five days. Final rate, APR, fees, loan amount, availability and approval depend on Figure’s prequalification and underwriting.

That soft-pull distinction matters while you are comparing possibilities. Figure says its personalized rate check uses a soft inquiry, while continuing to a full application involves a hard credit pull that can affect credit. An early rate check can help test a financing scenario; it is not a commitment to lend.

Compare ADU Financing Options: HELOCs, Cash-Out Refinancing & Construction Loans

Requesting and comparing loan estimates from multiple lenders can be helpful. Compare the disclosures you receive, including the payment schedule, APR, fees, appraisal or valuation process, prepayment terms and any conditions that must be met before funds are available.

Time Your ADU Financing Around Design, Permits & Construction

1. Save a design: Select a model and key options so the conversation starts with a real configuration.
2. Confirm the wider scope: Use the site review and project conversation to identify costs beyond the building.
3. Check current terms and compare offers: We recommend saving your design before checking a figure rate, so the financing target is tied to an actual project.
4. Align funds with commitments: Review the contract and lender requirements together. Permit timing, lender underwriting, delivery scheduling and site readiness are related, but they are not controlled by the same party.

Explore Local ADU Grants, Loans & Housing Assistance

Cities, counties, states and housing agencies sometimes offer ADU grants, low-cost loans, technical assistance or pre-approved plans. Availability is local and conditional, and these programs should be treated as possible supplements, not as money already available.

Confirm the application window, property eligibility, occupancy or rental restrictions, reimbursement rules and whether the program’s timing fits your project. Your local housing or planning department is a sensible first stop.

Plan Your ADU Financing Before You Borrow

Financing can make our ADUs achievable without requiring the full cost upfront. The responsible version begins with a complete scope, a payment that does not depend on a perfect future and lender disclosures you have compared carefully.

Start by designing and pricing your ADU. Then use that configuration to review current financing information, compare actual lender terms and talk with our team about the project items that belong in the budget.

ADU Financing FAQs

Can I use home equity to finance a Studio Home ADU?

Eligible homeowners can explore a HELOC, including our current Figure partner path, or compare another home-equity or refinance structure. The amount and terms depend on the property and the borrower’s underwriting profile; an online estimate is not a substitute for a lender’s final review.

Will future rental income from my ADU help me qualify?

Lender treatment of anticipated rental income varies by program, property, documentation and borrower profile. Do not assume it will be included. Ask the lender directly and make your own payment decision using a conservative household budget.

Does a HELOC put my home at risk?

Yes. A HELOC is secured by your home, and missed payments can put the home at risk. That is why the payment test matters as much as the credit-line amount.
