Do You Need a License to Sell Microgreens in California?

Usually yes, and this is the state where that answer differs most from the rest. But the thing you need does not come from Sacramento. It comes from your county.

Every other state page in this series leads with an exemption. California leads with a credential: to sell your own produce at a certified farmers market you need a Certified Producer's Certificate, and the county agricultural commissioner issues it. Your local environmental health department, also county, handles food facility permitting if your operation goes that way.

That is the single most important thing to understand about California. There is no one state office to call, and a page that quotes one fee or one plan review rule for the whole state is describing a system that does not exist.

The federal layer applies on top, and is the same everywhere. See the FDA Produce Safety Rule page.

Start with your county, because everything else depends on it

CDPH confirms it does not issue local permits, and directs people to their local agency. So "call the state" is not an answer in California, and the county you produce in is the first fact you need.

What each credential actually is

The direct marketing framework itself sits in Food and Agricultural Code 47002, which expressly covers California-grown fresh vegetables sold by a certified direct marketing producer. Alongside it, Health and Safety Code 114376 sets out the community food producer route, under which a raw whole vegetable can go direct to the public, to a food facility, or to a cottage food operation.

The label requirements, which are unusually specific

This is the part of California law most worth knowing, because it is concrete where other states are silent.

Under FAC 47002(c), every closed consumer container must show:

These are fixed statutory elements, not guidance. If you sell clamshells at a certified farmers market, that is your label, and getting it right costs nothing while getting it wrong is a straightforward citation.

A community food producer's packaged agricultural product must carry the producer's name and address under HSC 114376, and an on-site sale may use conspicuous signage instead of a label on each package.

Compare this with the other states in this series, where the honest answer to "what goes on my label" is usually "nothing state-specific is published". California tells you.

Cottage food, and the numbers people quote at you

California's Cottage Food Operation program is for approved foods prepared and packed in a private home. A growing crop is agricultural produce, so the CFO route is not the legal path for microgreens, and CDPH's approved food list is not where your answer lives.

For completeness, because these figures circulate: CDPH's program page states a Class A operator's current maximum gross annual sales are $75,000, and $150,000 for a Class B operator, read from the CDPH page on 6 August 2026. Class A sells directly to the public; Class B may also sell indirectly through restaurants and food markets. The ceilings are CPI adjustable, and CDPH has published different adjusted figures in earlier years, so read the current CDPH notice rather than any figure quoted in an article, this one included, once time has passed.

Neither number applies to raw microgreens.

Tax

Fresh food for human consumption is generally exempt from sales and use tax under Revenue and Taxation Code 6359, and CDTFA states that a seller making only fresh produce or cold food to go sales need not hold a seller's permit. A seller's permit is free if you do need one for other taxable sales, and a resale certificate is only for a genuine resale purchase.

California's agricultural tax benefit is chiefly a partial sales and use tax exemption on qualifying farm equipment and machinery used by a qualified person producing or harvesting agricultural products, set out in CDTFA's agriculture guide and Regulation 1533.1. Qualifying classifications include vegetable and horticultural production. A personal garden does not qualify, and the exemption is on what you buy rather than a food permit exemption.

Business registration. No single statewide registration or cost applies to every grower. A sole proprietor may need a county fictitious business name filing, an LLC or corporation registers with the Secretary of State, and cities commonly require a business tax certificate. Ask both the Secretary of State and your city.

Food safety, and where value-added changes everything

California layers direct marketing standards and the California Retail Food Code on top of the federal floor. The Produce Safety Rule remains the farm production baseline, administered through CDPH's Food and Drug Branch.

The line that matters for a microgreens grower is value-added handling. CDPH publishes guidance on produce in retail markets, and the practical effect is that washing, cutting or mixing greens calls for local retail food code review rather than an assumption that your raw crop position carries over. That is the same fork as every other state, with one difference: here the answer comes from your county, so two growers in different counties can genuinely get different answers.

Inspection. A farm may be inspected for federal compliance through the produce safety program, and a permitted food facility is inspected by county environmental health. No fixed statewide interval for a microgreens farm is published.

Food handler cards. Not required merely to grow and harvest raw microgreens. They attach to food facility employees under local enforcement, and CFO operators have their own training requirement within three months, which is not your route.

What changes by sales channel

Home growing, right to farm, and insurance

Home growing is controlled by county and city zoning, home occupation rules, building and water requirements, and any HOA. California has no uniform statewide home microgreens permit, and none of this is published in one place. Ask your city or county planning department before installing racks, signage, customer pickup or exterior alterations.

Right to farm. Civil Code 3482.5 can protect qualifying agricultural activities from nuisance claims after prescribed conditions are met. It does not override zoning, health rules or private agreements, and whether it reaches an indoor residential microgreens operation is fact-specific rather than settled.

Insurance. No California statute requires general or product liability insurance solely to sell raw microgreens. It can become mandatory through workers' compensation, vehicle use, a lease, a market's rules or a buyer contract. Buyers commonly want general and product liability, additional insured status, indemnity, recall cooperation, audits and traceability records, with limits set contract by contract.

What California does not publish

Eight open questions is more than most states in this series, and the reason is structural rather than sloppy: California devolves the answers to 58 counties, so a statewide page genuinely cannot close them.

The market

California has the largest population of any state and exceptionally dense restaurant and grocery markets in Los Angeles, the Bay Area, San Diego and Sacramento, alongside a mature specialty produce sector.

Both halves of that matter. The chef and retail opportunity is the best in the country, and so is the competition: you are selling into a market where buyers already have specialty produce suppliers and know what they are worth. No authoritative statewide count of microgreens growers is published, so validate your own metro with buyer outreach before setting a price rather than trusting any number you read.

Frequently Asked Questions

Q: What do I actually need to sell at a California farmers market? A: A Certified Producer's Certificate from your county agricultural commissioner, covering your own California production, plus compliance with the market's own rules. Your closed containers need the five FAC 47002(c) label elements.

Q: Who do I call, the state or the county? A: The county, for almost everything. The agricultural commissioner issues the certificate and environmental health handles food facility permits. CDPH is the contact for state produce safety questions and confirms it does not issue local permits.

Q: I want to wash and bag my greens. Does that change things? A: Very likely yes. Value-added handling is what turns a producer into a food facility, and CDPH's produce guidance points that determination to your county. Get it in writing first.

Q: Can I use the cottage food program? A: No. It covers foods prepared and packed in a private home. The $75,000 and $150,000 caps are real and irrelevant to a growing crop.

Q: Do I need a seller's permit? A: Not for selling only fresh produce. Food for human consumption is exempt, and CDTFA says such a seller need not hold a permit. If you sell taxable items too, you do, and the permit itself is free.

Q: What has to go on my label? A: Producer name, address, ZIP code, the identity of the commodity, and net quantity, on every closed consumer container, under FAC 47002(c). This is more specific than most states publish, so use it.

Final thoughts

California is the most demanding state in this series and the most clearly signposted, which is a strange combination until you see why. It asks for a real credential and it tells you exactly what your label must say. What it does not do is centralise, so the work is finding the right county office rather than deciphering an ambiguous rule.

Two things before your first market day. Get the Certified Producer's Certificate application moving with your county agricultural commissioner, because it gates everything else. And if you plan to wash or cut, ask county environmental health for a written determination now, since that single answer decides whether you are a producer or a food facility.

If something here does not match what your county told you, report it and it gets corrected. Your county's answer governs, and a page that is wrong about a rule is worse than no page.
