How to Finance an ADU in Salinas

The short version: most Salinas homeowners pay for their ADU by borrowing against the equity they already have, usually with a HELOC, a cash out refinance, or a construction loan. We do not lend money directly. What we can control is the price, and ours is all inclusive, so the number you finance is the number you pay.

Financing tends to be the first real hurdle people hit once they decide an ADU makes sense for their Salinas property. It is not that the process is complicated, it is that most homeowners have never borrowed this way before and no one wants to guess wrong on how much to ask a lender for. Here is how it actually works.

The common ways homeowners finance an ADU here

Most people paying for an ADU are not writing a check from savings. They are tapping the equity in the home they already own. The three paths we see most often are a HELOC, a cash out refinance, and a construction loan. Each one draws on your existing home equity differently, and each has real tradeoffs around rate, timing, and how the money gets released to you. We are not lenders and will not pretend to give you a definitive answer on which is right for your situation. For the full breakdown of how each works statewide, read our guide on how to finance an ADU in California. If you are trying to decide specifically between a HELOC and a construction loan, we wrote a side by side comparison here: HELOC vs construction loan for an ADU.

Why an all inclusive price matters when you are financing

A lot of ADU builders quote you a base number, then the real cost shows up later in draws and change orders: permits here, site work there, appliances tacked on at the end. That is a hard thing to finance around, because you do not actually know what you are borrowing for until you are already mid project. Our price is all inclusive, covering everything from permits through appliances, so the amount you finance up front is the amount you pay at the end. Because most of the home is built in our own factory rather than on your lot, the price is not drifting with whatever the crew finds once they start digging.

What it costs to get the process started

You do not need a loan locked in before you take the first step. Getting started costs a $1,000 signup deposit, which is refundable if your financing falls through. Before that, we run a feasibility study to confirm your property can actually host an ADU, which costs $497 for a standard lot or $997 if the lot is empty. That fee credits toward your build if you move forward, and it is refundable only if your property turns out not to be able to host an ADU. Both numbers are designed so you can find out what is possible before you commit to a loan amount.

Matching a model, and a loan amount, to your lot

Our lineup runs from a 450 square foot studio at $199,000 all inclusive up to a 1,200 square foot three bedroom at $599,000 all inclusive, with several sizes in between. Six of our models stay under 750 square feet, which under state law means they skip local impact fees entirely. Anything at 750 square feet or larger has impact fees, but those fees have to be proportional to the size of your main home, not an arbitrary add on. Knowing which bracket your model falls into ahead of time makes it a lot easier to land on the loan amount you actually ask for.

Will rental income help you qualify

Plenty of Salinas homeowners plan to rent the ADU out, and want to know whether that income can offset the payment. As planning estimates only, not guarantees, we use rent benchmarks of roughly $2,000 a month for a studio, $2,500 for a one bedroom, $2,950 for a two bedroom, and $3,450 for a three bedroom, alongside a net cash flow model that assumes 5 percent vacancy, 8 percent maintenance, property tax at 1.25 percent of the ADU cost per year, and insurance at 0.5 percent of the ADU cost per year. Bring these figures to your loan officer as a starting point for the conversation, not a promise of what you will collect.

How Salinas’s ADU rules affect your timeline, and your loan

Salinas rescinded its own local ADU chapter in 2026 and now applies state ADU law directly to applications. That means ministerial review, no public hearing, and a decision within 60 days of a complete application. That matters for financing because construction loans and HELOC draw periods run on a clock, and a predictable 60 day review window is a lot easier to plan a loan around than an open ended local process. Our factory is in Salinas, about a 5 minute drive from the permit counter, and we know that office by name. We have completed projects here and understand what the city expects on a complete application. For the process itself, read our guide to ADU permits in Salinas.

Frequently asked questions

How much money do I need before I start the process?

You need the $1,000 signup deposit, which is refundable if your financing falls through, plus the feasibility study fee of $497 for a standard lot or $997 for an empty lot. The feasibility fee credits toward your build and is refundable only if your property cannot host an ADU.

What is the difference between a HELOC and a construction loan?

Both borrow against your home equity, but they release funds differently and carry different rate structures. We cover the full comparison in our guide, HELOC vs construction loan for an ADU, rather than repeating it here.

Does Salinas’s 2026 rule change affect how I should finance my ADU?

It helps. Applying state ADU law directly means ministerial review with a 60 day decision window on a complete application, and impact fees are waived for any ADU under 750 square feet. Both make it easier to predict your timeline and your total cost before you finalize a loan amount.

Will the price change once construction starts?

No. Our price is all inclusive from permits through appliances, with a permitting budget built in, so you get a clear project cost before you sign. Exact permit fees and any property-specific site work are confirmed in your feasibility study, so you know what to borrow before you commit.
