Do You Need a License to Sell Microgreens in Arizona?

No, not for growing and selling your own whole, uncut microgreens direct to consumers. Arizona's food code excludes a produce stand offering only whole, uncut fresh fruits and vegetables from the definition of a food establishment, so there is nothing to be licensed as.

The answer turns to yes when the operation becomes a regulated food establishment, meaning you cut or process the greens or serve prepared food, or when you start acting as a wholesale produce dealer or shipper. It is a question about your activity, not your revenue.

The federal layer applies on top and is the same in every state. See the FDA Produce Safety Rule page.

Where the line sits

Arizona draws it at the produce stand exclusion, and the wording is doing precise work: only whole, uncut fresh fruits and vegetables. Both words matter, in the same way Ohio's "only" and Michigan's "uncut" do.

Two regulators, and they are not interchangeable. Your farm's food safety regulator is the Arizona Department of Agriculture, Plant and Produce Services Division, Office of Produce Safety. A county food establishment permit, when one is triggered, comes from the county environmental health authority rather than from ADHS centrally, per A.R.S. 36-136(I). Contact details for both are in the who to ask panel below.

Cottage food: no cap, and still not your route

Arizona removed the cottage food dollar ceiling. A.R.S. 36-932(D)(1) allows a registered preparer to sell to the maximum extent federal law allows, and states no dollar figure at all. That followed the 2022 expansion in HB 2042. It is a genuine legal change rather than an inflation adjustment.

It is still the wrong instrument for you. A.R.S. 36-931 defines cottage food as food prepared in a registered preparer's home kitchen. A microgreens crop is grown and harvested, not prepared, and the framework that governs it is the Produce Safety Rule. Refrigerating raw greens does not turn them into cottage food either.

One trap worth knowing if you sell to chefs: A.R.S. 36-932(F)(1) forbids a cottage food product being used as an ingredient in a permitted restaurant. A grower who mistakenly believes they are operating under cottage food has therefore also mistakenly believed they can supply restaurants. They are two errors stacked on one another, and the correct route avoids both.

Tax: your own crop is outside TPT entirely

This is Arizona's most useful and least publicised answer.

Sales of the producer's own food products are not subject to transaction privilege tax under A.R.S. 3-561 to 3-563, and the Department of Revenue says such producers need not obtain a TPT license for those sales. That is fixed statutory treatment, not an inflation-adjusted threshold that moves under you.

The exemption applies where the owner, proprietor or tenant of agricultural land, an orchard, a farm or a garden grows or raises the food product and sells it as the producer. It reaches food products, not ancillary non-food goods, so a tray of greens is covered and a branded tote bag is not.

Two things it is not. It is not a food safety or health permit exemption, which is a different question with a different answer. And it is not a reason to hold a resale certificate: a resale certificate documents a genuine wholesale purchase, so retain purchaser documentation for a real wholesale transaction and do not obtain one merely to retail your own crop.

Business registration. Arizona requires no general statewide business license for a sole proprietor. An LLC or corporation registers with the Arizona Corporation Commission, and a trade name is optional through the Secretary of State. There is no single figure to quote here because entity choice and city licensing both vary, so ask the Commission and your city.

Food safety, and the 24-hour clock

Arizona authorises AZDA to administer the federal Produce Safety Rule, under Title 3, chapter 3, article 4.1. The program covers worker hygiene, biological soil amendments, wildlife, pre-harvest and post-harvest sanitation, agricultural water and equipment. Microgreens are covered produce and are not Subpart M sprouts.

Three specifics worth acting on rather than just reading:

Records within 24 hours. The enacting statute requires a covered farm to keep its Produce Safety Rule and state records, provide them within 24 hours of an electronic or written request, and allow compliance inspections. A day is not long enough to build a record system from nothing. Build it before you are covered.

Inspection is on reasonable notice, except when it is not. AZDA inspects a covered farm on reasonable notice unless notice would impede enforcement, and may return to complete or follow up, and may investigate a public health hazard. Neither the statute nor AZDA publishes a fixed every-X-years frequency.

The readiness review has a prerequisite, and it is the kind that costs a season. AZDA's On-Farm Readiness Review is a confidential, non-regulatory assessment that helps you evaluate your practices and find gaps before an official regulatory inspection. AZDA is explicit that observations and feedback are decoupled from enforcement.

The catch is the order. AZDA states it plainly: "It is required that someone from your operation has attended the Produce Safety Alliance (PSA) Produce Safety Rule (PSR) Grower Training before scheduling an OFRR." Note the wording is someone from your operation, not you personally.

The training is worth doing on its own merits anyway, and this is the part that applies in every state rather than only in Arizona: completing the PSA Grower Training Course fulfils the federal requirement at 21 CFR 112.22(c) that at least one supervisor or responsible party has completed food safety training equivalent to the standardized curriculum. One course, two boxes ticked.

Water. For covered farms this is 21 CFR part 112, subpart E, because Arizona's statute incorporates the federal rule directly. FDA's water requirements and dates have changed, so treat any fixed testing interval you read elsewhere with suspicion and get the current position from FDA or AZDA rather than from a guide.

Labeling

Arizona publishes no state label checklist for packaged whole raw microgreens.

Do not borrow the cottage food label. Those elements are legally for cottage food, and putting a home-kitchen disclaimer on raw produce misrepresents what you are selling.

At federal level a packaged raw agricultural commodity is generally exempt from Nutrition Facts but must not be misbranded, per FDA's labeling guide. A sensible wholesale label identifies the commodity, the responsible business and address, lot or harvest information for traceability, and handling. Those are good practice and buyer expectations rather than an Arizona mandate.

Worth watching: HB 2334 (2026) would add produce label provisions if enacted and effective. It does not convert microgreens to cottage food and it is not a current requirement. Check its status before you rely on anything about it.

What changes by sales channel

Home growing, zoning and right to farm

Arizona has no single statewide home occupation rule, because zoning is local. Growing indoors at home may be a home occupation or an accessory agricultural use depending on your city or county, and the answer commonly changes with customer traffic, exterior storage, signage, structures and employees. Phoenix publishes home occupation standards through its planning and zoning materials.

A commercial kitchen is not automatically required to grow and harvest whole raw greens. It is triggered when the activity becomes regulated food preparation, processing or service under the county food code. Get written determinations from both the county and AZDA before you add washing, cutting, mixing, repacking or any ready-to-eat service.

Right to farm. Arizona's agricultural nuisance protections sit at A.R.S. 3-111 and following. Agricultural operations covers crop production activities, and farmland means land primarily devoted to commercial agricultural commodities. It is a nuisance defense framework. It is not a zoning, permit, health code or HOA exemption, and reaching for it to solve a zoning dispute will not work.

Insurance

No Arizona statute requires general or product liability insurance solely to grow and sell microgreens. It remains strongly advisable, because a foodborne illness claim is expensive and markets and retail buyers commonly ask for proof before they will deal with you.

Required insurance arrives from other directions instead: employees, vehicles, leases and contracts each carry their own triggers. Buyer contracts typically want commercial general liability and product or recall coverage, certificates naming the buyer as additional insured, indemnity, traceability and recall cooperation, and sometimes an audit. Those amounts are buyer-specific and are not Arizona law.

What Arizona does not publish

The market

Demand concentrates in the Phoenix and Tucson metros, where restaurant, grocery and farmers market channels are densest. Yuma is a major winter vegetable production region, which means serious commercial produce competition in the state even though microgreens are a differentiated indoor crop.

The climate cuts both ways for an indoor grower. Controlled environment production is the norm here rather than the exception, so you are not explaining the concept to anyone. Cooling load and water management are real business costs that a grower in a milder state does not carry to the same degree, and they belong in your numbers from the start.

Arizona publishes no count of microgreens competitors or current restaurant demand, so any statewide figure you see quoted is an estimate. Survey your own metro with buyer calls before you set a price.

Frequently Asked Questions

Q: Do I need a permit to sell microgreens at an Arizona farmers market? A: Not for your own whole, uncut greens. The Arizona Food Code excludes a produce stand offering only whole, uncut fresh fruits and vegetables from the food establishment definition, and Maricopa County says the same. The market itself may still require an application and insurance.

Q: Do I need a TPT license? A: Not for sales of your own crop. A.R.S. 3-561 puts a producer selling their own food products outside transaction privilege tax, and the Department of Revenue says no TPT license is needed for those sales.

Q: Arizona has no cottage food cap. Can I use that? A: The lack of a cap is real, per A.R.S. 36-932(D)(1), and it is still the wrong route. Cottage food is food prepared in a home kitchen. Your crop is grown, and it falls under the produce framework.

Q: I want to sell to restaurants. Anything special? A: Treat it as a produce safety and traceability transaction: invoices, lot identity, cold chain, supplier approval. And note that a cottage food product cannot be used as an ingredient in a permitted restaurant, which is another reason the cottage food route would have been a dead end.

Q: How do I get the free on-farm readiness review? A: Attend PSA Grower Training first. AZDA requires that someone from your operation has attended it before an OFRR can be scheduled, so book the course into your calendar early rather than discovering the prerequisite when you want the review.

Q: What if I cut and bag my greens? A: You are likely a regulated food establishment at that point, which is a county permit question. Get it in writing from the county and from AZDA before you start, not after.

Final thoughts

Arizona is a good state to sell microgreens in and a demanding one to grow them in, which is an unusual combination. The regulatory answer is clean, the tax answer is genuinely generous, and the free readiness review is worth having.

Two things to do early. Set up your records so you could hand them over in a day, because that is the standard once you are covered. And book the grower training, because it is the gate to the free review and it is the cheapest credibility you can hold in front of a buyer.

If something here does not match what AZDA or your county told you, report it and it gets corrected. A page that is wrong about a rule is worse than no page.

A note on AZDA's own pages

Some of AZDA's pages resolve and some do not, which is worth knowing before you go looking. The Produce Safety pages linked above are live and were read directly for this page. The older paths for the division landing page and its outreach section returned "Page not found" and an access denial when checked on 6 August 2026, so nothing here links to them.

Where a claim would have rested only on a page that did not resolve, it is not made. Every legal statement on this page is cited to Arizona statute or the Food Code, both of which are readable independently of how AZDA's website is behaving on a given day.
