Financing Your Sacramento ADU

How Homeowners Pay for an ADU

An ADU is a six-figure project for most people, so how you finance it matters as much as what it costs. The good news is that an ADU is one of the few home improvements that can pay you back — through rental income and added property value — which opens up financing options a pure remodel wouldn't. Here are the common ways Sacramento homeowners fund a build. (We're builders, not lenders or financial advisors — this is general information, and you should confirm specifics with a lender.)

Common Financing Options

• Home equity (HELOC or home equity loan) — the most common route. If you've built equity in your Sacramento home, you borrow against it, often at lower rates than unsecured debt.
• Cash-out refinance — replace your mortgage with a larger one and take the difference as cash for the build. Makes sense when rates are favorable.
• Renovation loans — loans that base your borrowing on the home's projected value after the ADU is built, which can unlock more than current equity alone.
• Construction or ADU-specific loans — some lenders offer products built specifically for ADUs, sometimes counting projected rental income toward qualifying.
• Cash or savings — straightforward when available, and avoids interest entirely.

The ROI Case

Here's why the numbers often work: a Sacramento ADU commonly rents for about $1,500 to $2,200 a month. On a unit that costs, say, $250,000 to build, that rent can cover a large share of the financing payment — and in many cases the ADU roughly pays for itself over time while the property's value rises. Even setting rent aside, an ADU typically adds meaningful resale value, so you're converting borrowed money into a durable asset rather than a cost that disappears.

Family Use Counts Too

Not every ADU is about income. Housing aging parents or adult children in a dedicated, private unit — instead of paying for assisted living or a separate rental — can be its own financial and personal return. The right financing plan depends on whether you're renting, housing family, or both.

Start with Real Numbers

The financing math only works once you know the real cost of your specific ADU. That's what the free consultation gives you: a realistic budget you can take to a lender, plus a clear picture of the rental income potential for your property. See the full Sacramento ADU cost guide to start.
