How to read this list.
We do not ask for your name, your email, or your number. Nothing on this page changes based on who you are.
A door is headquartered here when its head office sits inside the county line. The rest are based elsewhere and keep a branch you can walk into. We list both, and we label which is which.
Every institution on this page comes from public federal data — the CDFI Fund certified list (Aug 2026), NCUA credit union data (Mar 2026), and the SBA microloan intermediary list (Sep 2026) — plus a short national tier we verified by hand. We refresh each list as its agency publishes. No listing is paid.
Sonoma County runs on vineyards and wineries, hospitality, dairy, and the trades that keep all of it standing — which means financing here has to fit income that arrives in waves rather than in even monthly chunks. This guide explains what business financing actually is, who tends to qualify given how people earn a living in this county, which documents to gather first, and exactly which institutions are based inside the county line, which only keep a branch here, and which national nonprofits lend to ITIN holders. It also names the traps that hit Sonoma County contractors hardest.
It's a process, not a rejection.
Business financing is borrowed money — or, less often, grant money — used to start, steady, or grow work you already know how to do. It shows up in a few recognizable shapes:
- A term loan: one lump sum, set payments, a known end date. Good for a truck, a trailer, a walk-in cooler.
- A line of credit: an approved limit you draw from and pay back as you go. Good for the gap between doing the work and getting paid for it.
- A microloan: a smaller loan, usually from a nonprofit or mission lender, often bundled with free coaching. Good when your books are thin or the business is young.
- Equipment financing: the machine is the collateral, so the decision leans on the equipment as much as on you.
- Grants: real, but rare, competitive, and never fast. Treat them as a bonus, not a plan.
Sonoma County's economy is specific, and the specifics decide which of those shapes fits you. Vineyards and wineries set the calendar — pruning in winter, crush in fall, and a long list of contractors moving between both. Tasting rooms, lodging, restaurants, and event work carry the visitor economy from the coast and the Russian River.
Dairy and poultry operations anchor the west county around Petaluma.
And the rebuild work that followed the wildfires kept framers, roofers, electricians, grading crews, and tree services busy well past the fires themselves. Santa Rosa is where most of the county's financial offices actually sit.
What that means practically: a lot of income here is seasonal and lumpy. A lender who only looks at one slow month will misread you. Your job in an application is to show the whole cycle.
Forget what the banks say.
Institutions weigh roughly five things: whether you can repay, what your credit file says (or what stands in for it if the file is thin), how long you have been doing this work, what collateral exists, and whether the plan makes sense in this particular market.
Work that reads well to a Sonoma County lender includes:
- Vineyard management, pruning, and harvest crews that have gone independent
- Winery service work — mobile bottling, barrel and cellar contracting, tank cleaning
- Landscaping, hardscape, irrigation, and defensible-space clearing
- Licensed trades doing rebuild, remodel, and hardening work on homes
- Food trucks, caterers, and event crews serving tasting rooms and weddings
- Dairy and feed hauling, ag equipment repair, and livestock services
- Housekeeping and janitorial contracting for lodging and short-term rentals
- Owners of a few rental units who want to fix or expand what they hold
If your income is seasonal, bring two or three years of history rather than three months. A crew that earns most of its money between pruning and crush is not a risky business; it is a normal Sonoma County business, and a local institution knows that. A lender in another state may not.
If you file taxes with an ITIN rather than a Social Security number, you are not automatically out. Some institutions lend to ITIN holders and some do not, and the policy is rarely posted on a website.
Ask the question directly, early, before you hand over documents.
A thin credit file is the same situation: nonprofit microlenders and credit-building programs exist precisely for that case.
Get your papers in order.
Every institution keeps its own checklist, but the following covers most of what gets asked for in California. Having it in one folder changes the tone of the conversation — you stop looking like a risk and start looking like an operator.
- 01Government photo ID
California issues a driver's license to residents regardless of immigration status; ask each institution which IDs it accepts before you assume.
- 02Your ITIN or Social Security number
- 03Fictitious business name (DBA) filing from the county clerk, or LLC and corporation papers filed with the Secretary of State
- 04Your state contractor license number, if your trade requires one
- 05Two years of personal tax returns
Including Schedule C, plus business returns if you file them
- 06Three to six months of business bank statements
The real account, not a personal one you also use
- 071099s from wineries
Vineyard management companies, and general contractors who pay you
- 08Simple profit-and-loss sheet
One page you typed yourself is better than nothing, and lenders say so.
- 09A list of equipment and vehicles, with what you still owe on each
- 10Lease
License, or property agreement if you work from a yard, shop, or commercial kitchen
- 11Certificates of insurance and workers compensation if you run a crew

The doors worth knowing.
Work this list in order. The institutions closest to home are the ones most likely to understand a crush-season cash flow, and the national nonprofits at the end are the ones most likely to work with an ITIN.

Don't fall into these traps.
The people who get hurt worst here are usually the ones with real work on the books and a temporary cash gap. That is exactly who predatory funders shop for.
These are not loans. A funder buys your future revenue at a discount and debits your account daily or weekly. The paperwork hides the true cost, and the debits do not pause when the season slows. Treat an MCA as the last option, never the first.
A legitimate institution does not collect a large fee before you have money in hand. If someone wants a payment to submit your application, walk.
Taking a second advance to cover the first is how a repairable cash gap becomes a closed business. If a funder offers you money specifically to pay another funder, that is a warning, not a solution.
Read what you are pledging. Some agreements let a funder collect without going to court, or attach every piece of equipment you own to a small advance.
If you asked for Spanish and the documents arrive in English only, that is not a paperwork problem, it is a sales tactic. You have the right to understand every line before you sign.
Any offer timed to crush or to a permit deadline — money today, sign now, the rate changes tomorrow — is using your calendar against you. Real institutions will still be there next week.
Nobody legitimate asks for a fee, an ITIN, or a bank login over text or social media to release grant money.
Everything below is set by California, and it reads the same in every county in it. The 6 marks above are this county's own doors — who opens one is decided by them, not by the state.
The rules where you are.
A few state-level rules shape the paperwork here more than most people expect.
A DBA filed with the county clerk, or an entity filed with the Secretary of State, is what turns your work into a business on paper. Most institutions will not open a business account without one, and without a business account your bank statements cannot tell your story.
Most construction work above a small dollar threshold requires a license from the state contractors board, and the board — not the lender — sets that line. General contractors and wineries both verify licenses before they issue you a 1099, so the license is a financing document even though it does not look like one.
California requires coverage once you have employees. Lenders ask for the certificate, and so do the general contractors who hire you.
California requires many commercial financing offers — including merchant cash advances — to come with a written disclosure of the total cost and an annualized rate. If a funder will not put that sheet in your hand, you have learned what you needed to know about that funder.
The small-business technical assistance centers in California are paid for already. Using them does not cost you anything and does not obligate you to borrow.
The short version.
- 01
If you run a business, a crew, or a one-person trade in Sonoma County, you have real options. This county of roughly 488,000 people has one CDFI based inside its line, in Windsor, three credit unions headquartered in Santa Rosa, two more keeping branches here, and three national nonprofits that lend to ITIN holders.
- 02
Do these things in order. Get a DBA or entity on file. Open a real business account. Pull two years of returns, six months of statements, and your 1099s into one folder. Then call the closest door first and the national nonprofits second — and ask each one, plainly, whether they lend to ITIN borrowers and whether they report your payments to the credit bureaus.
- 03
Compare at least two offers before you sign anything. Ask for the written cost disclosure on any commercial financing offer. If the answer is urgency instead of paper, you have your answer.
