California Cottage Food Operations: Class A vs. Class B, the $150,000 Cap, and the 2026 Compliance Map

California runs the cottage food program through two classes, 58 county environmental health offices, and a separate MEHKO track for hot food. Here is what the rules actually permit in 2026, the difference between Class A and Class B, the foods that quietly disqualify you, the labels that pass an inspection, and the Microenterprise Home Kitchen path you should know exists before you stretch the cottage food rule too far.

A county environmental health inspector is at your front door in El Cajon. A neighbor reported your kombucha — they saw it on a community Facebook page and were not sure if it was legal. The inspector wants three things: your cottage food registration, your food handler card, and a sample of your label. You have a registration. You have a card. The label says "Homemade in California" instead of the words the regulation actually requires, and the kombucha was never cottage food in the first place. The conversation is about to take longer than ten minutes.

California runs the cottage food program differently than almost every other state, and most of the trouble producers get into starts with reading advice that was written for somewhere else. The two-class system, the county-by-county administration, the narrow approved-foods list, and a separate MEHKO program for hot food make California more capable than its reputation — and more procedural. A producer who learns the rule in one afternoon can build a real business. A producer who guesses at the rule will spend their first year repeating mistakes the system politely points out one inspection at a time.

This is the long version of California cottage food law as it stands in 2026. It walks through the two classes and what the choice actually means, the gross-revenue caps and how to track against them, the food list (and the contrasts with Texas and other states), the labels that pass an inspection, the foods that quietly disqualify you, the Microenterprise Home Kitchen path you should know exists before you outgrow cottage food, and the county-level variation that makes the same rule feel like a different rule depending on where you live.

The short version: California cottage food law (the Homemade Food Act, AB 1616 of 2012, with later amendments) permits in-state sales of approved non-potentially-hazardous foods through two operator classes — Class A (direct only) and Class B (direct plus indirect retail) — under separate gross-revenue caps codified in California Health and Safety Code §113758. The statutory bases are $75,000 (Class A) and $150,000 (Class B), both adjusted annually for inflation by the California CPI under AB 1144 (2021). Registration is administered county-by-county. The approved-foods list excludes most acidified, fermented, refrigerated, and meat products. Labels must be in English with the home-kitchen disclosure in 12-point type. A separate MEHKO program (AB 626 of 2018, expanded by AB 132 of 2023) handles hot, refrigerated, and perishable food in counties that have opted in. Interstate shipping is not allowed under either program.

Why California is different from every other state

California cottage food law looks superficially like other state cottage food laws. The same approved-foods archetype — bread, jam, dried herbs, granola, candy. The same prohibition on interstate shipping. The same broad framing as a non-potentially-hazardous-food carve-out from commercial kitchen requirements. Three structural features set California apart:

  1. The two-class system. Almost every other state has a single cottage food framework. California has two: Class A for direct-to-consumer sales (your home, farmers markets, in-state delivery) and Class B for direct plus indirect sales through restaurants, grocery stores, and other retailers. Class A is lighter to register and cheaper to operate. Class B requires a permit, a kitchen inspection, and an annual renewal — but unlocks a wholesale-style channel that direct-only states explicitly prohibit. Producers who pick the wrong class spend money they did not need to spend or, worse, sell in a channel they were not registered for.
  2. County-by-county administration. California has 58 counties and 58 environmental health departments. The state law sets the floor; each county runs its own registration form, its own inspection booking flow, its own fee schedule, and its own follow-up process. The Texas DSHS produces one form for the whole state. In California, the same producer moving from Sacramento County to Yolo County repeats the registration with a different office and possibly a different fee.
  3. The exclusion of acidified and fermented goods. Texas allows pH-controlled hot sauces, pickled vegetables, fermented sauerkraut, and similar acidified products. California does not. The California list permits jams, jellies, preserves, and fruit butters, and a narrow set of vinegar-based products, but excludes hot sauce, pickles, kraut, kimchi, kombucha, and most fermented foods. A producer who reads a Texas guide and assumes the rules transfer will end up with a product they cannot legally sell from home.

The flip side: California also offers a route for hot, refrigerated, and perishable food through the Microenterprise Home Kitchen Operation (MEHKO) program — a separate authorization that does not exist in most states. MEHKO is more restrictive on volume but more permissive on what counts as food. Producers whose product is excluded from cottage food (a meal prep service, a hot tamale operation, a perishable-cake business) often find the right home in MEHKO instead.

What California cottage food law actually permits

The legal authority is California Health and Safety Code §113758 (the approved foods list and CFO definitions) and §114365 et seq. (cottage food operations), originally enacted by AB 1616 (the Homemade Food Act) in 2012 and amended several times since — most consequentially by AB 1144 (2021), which raised the revenue caps from a uniform $50,000 to the current two-tier structure. The California Department of Public Health (CDPH) sets the statewide rule, but registration and enforcement live at the county level through each county's environmental health office.

California defines a Cottage Food Operation (CFO) as a person who, in a private home, prepares or packages non-potentially-hazardous foods for direct sale to a consumer (Class A) or for direct and indirect sale through a third-party retailer (Class B), and who stays under the gross-revenue ceiling for the chosen class. Several elements of that definition matter:

  • An individual or household. A CFO is registered to a person at a specific residential address. LLCs and corporations cannot register a CFO; the operator is a natural person. A married couple may operate a single CFO together. Hired help (other than the operator's family members in the household) is not permitted in the cottage food kitchen.
  • In a private home. Production happens in your residential kitchen — not a separately licensed commercial space, not a rented community kitchen, not a detached structure on the property unless that structure is part of the residence. The kitchen must be on the same property as the operator's residence.
  • Approved non-potentially-hazardous foods only. The list is narrow and explicit. Foods not on the list are not cottage food, regardless of how harmless they seem at room temperature.
  • Direct or direct-plus-indirect, depending on class. Class A: direct consumer only. Class B: direct consumer plus indirect through retailers.
  • Under the cap for the chosen class. Once gross sales cross the cap, the operator either steps up to commercial production or stops selling for the rest of the calendar year.

The food list

The list of permitted foods has expanded modestly since 2013. As of 2026, California cottage food permits the following:

Category Examples Notes
Baked goods without cream, custard, or meat fillings Cookies, breads, scones, biscuits, muffins, pies (fruit-only fillings), tortillas, focaccia Excludes anything with cream cheese frosting, custard fillings, or meat. Pies are limited to fruit fillings — pumpkin, sweet potato, and dairy-custard pies are excluded from the basic list, though some are conditionally allowed.
Candy and confections Chocolate, fudge, brittle, caramels, hard candy, marzipan, cake decorations Excludes anything with raw eggs, alcohol-filled chocolates, or refrigerated fillings.
Roasted coffee and dried tea Whole bean, ground coffee, loose-leaf tea, tea blends (non-medicinal) Brewed beverages are excluded. Medicinal claims push the product into a different regulatory category.
Dehydrated produce Dried fruits, dried vegetables, fruit leather, dried herbs Must be properly dried to a safe water activity.
Cereals, granola, trail mixes, and popcorn Granola bars, kettle corn, caramel corn, trail mixes
Dry baking mixes Cookie mixes, brownie mixes, pancake mixes, soup mixes Must be packaged dry. Adding wet ingredients before sale is excluded.
Honey Raw and processed honey One of the narrower categories; check whether your county requires a separate apiary registration.
Jams, jellies, preserves, and fruit butters Strawberry jam, fig preserves, apple butter Must meet defined sugar and acidity thresholds (the standard high-sugar, low-water-activity preserves). Tomato jams and pepper jellies are excluded under most county interpretations.
Vinegar (without low-acid foods) Fruit-flavored vinegars, herb-infused vinegars Adding cucumbers, onions, or garlic crosses into "acidified" territory and is excluded.
Mustard Whole-grain, flavored Must be a properly acidified mustard, not a fresh mustard requiring refrigeration.
Dried pasta Egg or eggless dry pasta Must be fully dried for shelf stability.
Nut butters Peanut butter, almond butter, cashew butter Recent addition under amendments; verify with your county.
Roasted nut mixes Spiced almonds, candied pecans, nut brittles

The list excludes anything that requires time-temperature control for safety. That means no fresh meat, no jerky, no fresh dairy, no soft cheeses, no fresh juice, no kombucha, no fish, no products containing raw seafood, no quiches, no cheesecakes, no custard pies, no most cream-based fillings. The list also excludes acidified products generally — hot sauce, salsa, pickles, sauerkraut, kimchi, fermented vegetables. Anything regulated as a dietary supplement under federal law — herbal tinctures, CBD products, "wellness" formulations — falls outside cottage food entirely.

Sidebar — Pet treats are not California cottage food. Dog cookies, horse treats, and similar products are governed by the California Department of Food and Agriculture's commercial feed program, not the cottage food law. Even a "human-grade" dog cookie made in a home kitchen falls outside the state cottage food exemption and into AAFCO labeling territory. If you make pet products, treat them as a separate regulatory track and start with the pet treat packaging and labeling guide.

Class A vs. Class B: pick the right one before you register

The single decision that defines the shape of a California cottage food business is which class you register under. The choice affects sales channels, fees, inspections, recordkeeping, and what you can put on a label.

Class A — Direct sales only. A Class A CFO sells directly to the consumer, period. The buyer comes to your home, finds you at a farmers market, picks up at a community event, or accepts delivery from you within California. No grocery store, no restaurant menu, no retail shelf, no third-party reseller. Class A registration is filed with the county environmental health office, requires no in-person kitchen inspection, and renews on a schedule the county sets (often annually). Fees are modest and vary by county — for reference, Los Angeles County publishes its current cottage food fee schedule in its environmental health packet, and most counties post their own. A Class A operator who is caught selling indirectly through a retailer is operating outside their authorization.

Class B — Direct plus indirect sales. A Class B CFO sells directly and through third-party retailers — restaurants, grocery stores, cafes, gift shops, farm stands operated by someone else. Class B requires a permit (not a registration), a one-time inspection of the home kitchen by county environmental health, and an annual renewal. Fees are higher than Class A and again vary by county — check your county environmental health website for the current schedule. The inspection looks for hand-washing facilities, a sink dedicated to food preparation, separation of pets from the production area, and basic sanitation. Most California cottage food kitchens pass on the first try if the operator has prepared.

A simple decision rule:

Your sales plan Recommended class
Farmers markets, your own home, occasional pop-ups, in-state online orders shipped by you Class A
Any sale through a retailer, restaurant, grocery store, cafe, gift shop, third-party market organizer Class B
Mix of direct and "the local coffee shop wants to carry my granola" Class B
Wholesale-curious from day one Class B
Hot, refrigerated, or perishable food Neither — look at MEHKO

Producers underestimate how often a "small favor" pushes them across the line. A neighborhood cafe asks if they can stock five jars of your jam on a shelf next to the register. The cafe is reselling — that is indirect sale. A Class A registration does not authorize it. Either decline the placement, upgrade to Class B, or arrange the sale as a sample/giveaway with no money changing hands. The class distinction is not optional; the consequences of getting it wrong are not bureaucratic theater.

Sidebar — Switching classes mid-year is allowed. If you start as Class A and find a wholesale opportunity, you can apply for Class B with your county. Pay the higher fee, schedule the inspection, and continue operating once the permit is issued. Processing time depends on the county and inspector availability — verify the current turnaround with your county environmental health office before scheduling a retail launch around it.

The cap and how it works

Both classes operate under gross-revenue ceilings that reset on January 1 of each calendar year. The statutory bases set by Cal. Health and Safety Code §113758 are $75,000 (Class A) and $150,000 (Class B), both raised to these levels by AB 1144 (2021) from a uniform $50,000 base. Both ceilings are adjusted annually for inflation by the California Consumer Price Index — so the actual lines for any given year sit somewhat above the statutory base. Verify the current-year inflation-adjusted figures on the CDPH cottage food page before you commit to a planning number. Two facts about the cap are worth memorizing:

It is gross, not net. Every dollar of receipts from cottage food sales counts. Sales tax that you collect and remit? Counts (the rare California sale that is taxable). Shipping fees that you charge and pass through to the carrier? Counts. The cost of the flour you bought to make the bread? Does not reduce the gross figure. A producer with $80,000 in gross sales and $30,000 in COGS is at $80,000 of cap usage, not $50,000.

It is calendar year, not rolling. The cap resets January 1. A producer who hits the ceiling in November can resume on January 1. A producer who hits it in February has eleven months without cottage food sales. Some seasonal businesses schedule heavy production into Q4 of one year and the spring of the next so the calendar boundary cuts the year cleanly.

A few examples of how the cap math actually plays out:

Scenario Annual gross Class B base usage Status
Sourdough baker, weekend farmers markets $11,400 8% Well under
Custom-cake decorator, wedding orders $42,000 28% Comfortably under
Cottage chocolatier with a few cafe accounts (Class B) $86,000 57% Mid-range; healthy
Hot-sauce — wait, hot sauce isn't on the list n/a n/a Not cottage food in California
Granola producer scaling toward retail $138,000 92% At-risk; track every sale and start the commercial-kitchen plan
Multi-product baker scaling fast $172,000 115% of base Over the $150,000 statutory base — likely over the inflation-adjusted line too. Out of compliance for the calendar year unless verification against the current CPI-adjusted ceiling shows otherwise.

(Percentages above use the $150,000 statutory base for arithmetic clarity. The actual current-year line is slightly higher because of the CPI adjustment — confirm against CDPH before planning a Q4 push that depends on the exact figure.)

The mistake at the bottom of the table is the most common pattern across cottage food enforcement actions. The wider $150,000 Class B ceiling postpones the moment of crossing but does not eliminate it. Producers run a profitable operation for two or three years, the orders pile up, and they cross the cap mid-year without noticing. By the time they do notice, they have either stopped accepting orders, started running shipments through someone else's licensed kitchen, or kept selling and hoped the gap closed. The third option ends careers. CDPH and the county do not audit every producer, but a single complaint can trigger a review that pulls bank statements, marketplace payouts, and farmers market organizer records.

The practical defense: track gross revenue every single week, against a cap counter that everyone in the household can see. A simple spreadsheet column or a dashboard widget set to flag at 80% of the annual cap is the difference between landing safely and stopping mid-October because the books were not watched.

Sales venues: where California lets you sell

The full venue picture as of 2026:

Venue Class A? Class B? Notes
Producer's home Yes Yes Direct sale to a buyer who picks up.
Certified farmers markets and certified producer markets Yes Yes Most common venue. Many markets require you to provide your registration or permit and a current food handler card before booking a stall.
Online sales (within California) Yes Yes Buyer must be in California; product delivered or shipped within the state. The cottage food disclosure must be communicated to the buyer at or before checkout.
Mail order (within California) Yes Yes USPS or carrier, in-state delivery only.
Roadside stands and farm stands Yes Yes Including pop-up markets and seasonal stands.
Charity bake sales and community events Yes Yes Generally permitted; some local jurisdictions add temporary food event permits.
Restaurants, cafes, food service No Yes Indirect sale — Class B only.
Grocery stores, supermarkets, gift shops, retail shelves No Yes Indirect sale — Class B only.
Out-of-state shipping No No Federal jurisdiction; FDA does not recognize cottage food.
Out-of-state markets and craft fairs No No Same reason.
Etsy, Amazon, Shopify with national reach No No Cottage food cannot ship interstate, and most platforms route orders to any state by default.

The hardest line to hold is the platform line. A producer who lists cottage food on Etsy, Amazon Handmade, or Shopify with no shipping geofence will accept an order from Oregon or Nevada, ship it, and collect a payment that the platform records permanently. The platform does not police state cottage food rules — that compliance is on the producer. Some operators solve this by setting "ship to California only" filters on their store; others by moving production to a commercial kitchen and abandoning the cottage food exemption. There is no third option that keeps the exemption and serves a national customer base.

Sidebar — Online sales require disclosure at checkout. Direct cottage food sales over the internet require that the cottage-food disclosure ("Made in a Home Kitchen") be communicated to the buyer at or before purchase, not just on the package. A Shopify store that ships California cottage food without showing the disclosure on the product page or at checkout is technically out of compliance even if the physical label is correct.

The label every California cottage food package needs

The label is non-negotiable. Producers can be otherwise perfectly compliant and still receive a notice for a missing label element. The required components, as of 2026:

Element Specification
Home-kitchen disclosure Verbatim — "Made in a Home Kitchen" OR "Registered or Permitted by [County Name] Environmental Health" — in 12-point or larger type. This is the element county inspectors check first.
Cottage food operation name The registered name of the CFO. A business name and the operator's individual name may both appear, but the registered CFO name must be present.
Registration or permit number The county-issued CFO number. Class A operators include the registration number; Class B operators include the permit number.
Product name Common name of the product (e.g., "Sourdough Bread," "Apricot Preserves," "Vanilla Bean Granola").
Ingredient statement All ingredients in descending order by weight. Sub-ingredients must be listed for compound ingredients (e.g., "chocolate chips (sugar, cocoa, soy lecithin)").
Allergen statement A "Contains:" statement for any of the major nine allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soybeans, sesame). Sesame was added by federal law via the FASTER Act of 2021 and is mandatory on labeled food introduced into interstate commerce on or after January 1, 2023 — see the FDA's allergen guidance.
Cross-contact statement (where applicable) "Made with equipment that also processes [allergen]" where the same kitchen handles other allergens.
Net weight or volume In both metric and US customary units (e.g., "Net Wt 4 oz / 113g").
English-language requirement Labels must be in English. Producers may add additional languages, but the English version must contain every required element.
Production identifier (Class B sold at retail) A code that identifies the production date or batch, so a recalled batch can be traced. Class A and Class B direct sales do not require a date code, though many operators include one for inventory and recall planning.

For online sales, the home-kitchen disclosure must be visible at or before checkout — typically through a banner, a checkbox, or a confirmation email — in addition to the physical label.

Sidebar — Allergen labeling is where most enforcement actions land. A label missing a "Contains: wheat, eggs" statement is the single most common reason a county inspector sends a notice. The reason is straightforward: when a customer with a wheat allergy reacts to an unlabeled cookie, the complaint chain is fast, documented, and unambiguous. Treat allergen statements as the first thing you double-check on every label, not the last.

Required training: the food handler card

Every California cottage food operator (and any household member who helps prepare or package the product) must complete an accredited food processor or food handler training course within three months of registration or permitting and renew every three years during operation, per Cal. Health and Safety Code §114365.2(d). The course is delivered online by ANSI-accredited providers, runs about two hours, and is offered at low cost (most providers list current prices on their order page). You receive a card or certificate that is valid for three years from the date of issuance under Cal. Health and Safety Code §113948.

The card must be retained by the operator and produced on request by a county environmental health inspector. There is no central registry where the county looks up your status — the burden of proof is yours. Most operators keep a digital copy on their phone, a printed copy in their kitchen file, and a third copy with their tax records. When the card expires, you renew before continuing to sell. Producing without a valid card is a basic violation that can be cured, but a complaint discovered during a lapse is a more serious record.

The CDPH maintains the canonical list of accredited providers. Common options include:

  • StateFoodSafety
  • Learn2Serve / 360training
  • ServSafe California
  • eFoodHandlers
  • Always Food Safe

The course covers basic food safety: handwashing, time-temperature control, allergen handling, cross-contact, sanitation. Most operators find it educational rather than punishing, especially the allergen sections.

The acidified-and-fermented exclusion (and why California is stricter than Texas)

This is the section that catches the most experienced cottage food producers off guard, particularly producers who learned the rules in another state. California excludes acidified and fermented products from the cottage food list almost entirely:

  • Hot sauce — excluded. A California hot-sauce maker who wants to sell legally must produce in a permitted commercial kitchen with an FDA acidified-foods scheduled process. The path is real but expensive; see the hot sauce compliance guide for the full walk-through.
  • Pickles, sauerkraut, kimchi, fermented vegetables — excluded.
  • Salsa, chow-chow, relishes — excluded.
  • Kombucha, water kefir, fermented sodas — excluded as TCS / acidified.
  • Acidified canned goods generally — excluded.

The narrow exceptions:

  • Jams, jellies, preserves, and fruit butters — allowed, because they meet defined high-sugar / low-water-activity thresholds that suppress microbial growth without requiring acidification controls.
  • Mustard — allowed if properly acidified at the recipe level (not a low-acid fresh mustard).
  • Vinegar without low-acid solids — fruit-flavored or herb-infused vinegars are allowed; the moment cucumbers, onions, garlic, or other low-acid solids enter the bottle, the product becomes "acidified" and falls outside cottage food.

If your business plan depends on a product California excludes, you have three legal paths:

  1. Move production to a permitted commercial kitchen. Rented commercial kitchens in California are widely available (search for "shared commercial kitchen" or "commissary kitchen" plus your metro area); hourly rates and storage fees vary significantly by region and kitchen. The kitchen handles facility licensing; you still need product-level FDA registration for acidified foods.
  2. Look at MEHKO if the product is hot, refrigerated, or perishable. MEHKO does not solve the acidified-foods problem — it solves the hot-and-perishable problem. Hot sauce is still out.
  3. Contract with a co-packer. Many California co-packers will produce small batches under their own facility license. The economics work above a few hundred units per run; below that, the per-unit cost is usually painful.

Sidebar — California is the exception, not the rule. Texas allows pH-controlled hot sauces and pickles under cottage food. Pennsylvania, Ohio, and several other states permit a wider acidified list than California. A maker who learns the California rule and assumes it applies in their next state will over-restrict themselves; a maker who learns the Texas rule and assumes it applies in California will under-restrict and end up out of compliance. Use the Cottage Food Laws by State reference when comparing.

MEHKO: the Microenterprise Home Kitchen alternative

California is one of the only states with a parallel program for hot, refrigerated, and perishable home food production. AB 626 (2018), effective 2019 and expanded by AB 132 (2023), authorized Microenterprise Home Kitchen Operations (MEHKO) as a separate permit class administered by county environmental health departments — but only in counties that have actively opted in.

MEHKO basics:

  • What you can sell. Hot, refrigerated, or perishable meals prepared and sold directly to consumers. This is the program for tamale operations, meal prep services, hot-food delivery, perishable cakes, and similar businesses that cottage food explicitly excludes.
  • Volume cap. 30 meals per day, 90 meals per week, $100,000 gross per calendar year. AB 132 (2023) raised the original AB 626 weekly cap from 60 to 90 meals and the annual cap from $50,000 to $100,000 — verify against the COOK Alliance MEHKO FAQ for any further legislative updates. The daily and weekly caps are tighter than cottage food; the annual cap is in the same ballpark as Class A cottage food.
  • Sales channels. Direct to consumer only — no indirect, no third-party retail. MEHKO sells from the operator's home, by pickup, by in-county delivery, or through approved third-party platforms.
  • Permitting. County environmental health, with a kitchen inspection. Annual renewal.
  • County opt-in. MEHKO is only available in counties that have actively authorized it. Approximately a dozen California counties have opted in as of 2026 — verified counties include Riverside, Santa Clara, San Mateo, Lake, Imperial, Stanislaus, Solano, Alameda, Sacramento, San Bernardino, and Los Angeles. The opt-in list grows as more counties act, so confirm against the COOK Alliance county tracker or your county environmental health office before relying on a specific list.

If your product is excluded from cottage food because it is perishable or requires refrigeration, MEHKO is the question to ask before you commit to renting commercial space. It is not the answer for every producer — the daily meal cap is real, the sales channels are limited to direct, and the county-opt-in patchwork means producers in non-opt-in counties have no MEHKO path — but for the businesses it fits, MEHKO is a legitimate home-based commercial option.

What California cottage food law does not cover

The state law is one layer. Three other layers can apply on top of it, and producers are responsible for finding them.

Local zoning and HOA restrictions

AB 1616 and the implementing language in Cal. Health and Safety Code §113758 limit a city or county from prohibiting cottage food operations outright in residential zones, but local governments may impose reasonable restrictions on traffic, parking, signage, hours, and external impacts. HOA covenants are private agreements that operate alongside zoning — California courts have generally enforced HOA restrictions on home-based commerce. Read your CC&Rs before you scale, especially in master-planned communities and condo associations. A cottage food operator who attracts heavy in-and-out traffic for pickups can trigger neighbor complaints that escalate to HOA enforcement quickly.

County-level additions

Each of California's 58 counties administers cottage food through its own environmental health department, with its own forms, fees, and inspection process. Some counties add training requirements, additional documentation, or fee structures the state law does not require. The state rule is the floor, not the ceiling — counties can add, they just cannot subtract. Before you register, download your county's specific cottage food packet from the county environmental health website. Do not rely on a neighboring county's forms.

Sales tax (when it applies)

Most cottage food sales in California are exempt from sales tax because most prepared baked goods and grocery-style items qualify as exempt food products under CDTFA Publication 22 — Tax Tips for the Dining and Beverage Industry and the underlying California Code of Regulations Title 18 §1603 (Taxable Sales of Food Products). The exemption fails when the item is sold as a hot prepared food, with utensils provided, in a manner intended for immediate consumption, or as part of a combination sale that includes a non-food container. The cottage food exemption is a food-safety carve-out, not a tax determination. To collect sales tax legally on the sales that are taxable (a celebration cake delivered with a serving knife, for instance), you need a CDTFA seller permit. Failing to collect tax on taxable sales is a separate violation from cottage food, and CDTFA is more aggressive on enforcement than the county.

Federal labeling for shipping (which you cannot do anyway, but)

If a cottage food operator transitions to a commercial kitchen and starts shipping interstate, federal labeling rules add nutrition facts panels (with exemptions for small businesses), bilingual labeling for imported goods, and FDA facility registration. None of that applies under California cottage food, but the moment a producer crosses into commercial production, the federal floor lifts.

Common mistakes California cottage food producers make in year one

Patterns repeat. The seven most common compliance failures, in rough order of frequency:

  1. Wrong-class registration. A producer who only sells at farmers markets registers as Class B, pays the higher fee, and never uses the indirect channel. Or — worse — a Class A producer sells two jars of jam on the shelf at the local cafe and is now operating outside their authorization.
  2. Missing or incomplete allergen statement. A "Contains:" line absent on a product with wheat, eggs, or dairy. The cure is mechanical — every label, every batch, every time.
  3. Selling acidified or fermented products. A producer reads a guide written for Texas or Pennsylvania, makes a batch of hot sauce, and lists it on Etsy. The product is not California cottage food. Pull it before a customer with a complaint pulls it for you.
  4. Untracked gross revenue. A producer assumes they are at "maybe $40,000" and is actually at $112,000 by November because the farmers market booth was busier than memory suggests. The cure is a weekly revenue log. The wider $150,000 Class B ceiling makes this less catastrophic than it used to be — but only marginally, because cap-blowers tend to undercount by a wide margin.
  5. Out-of-state shipping by accident. A Shopify store with no shipping geofence accepts an order from Oregon. The producer ships it. The order is technically illegal — and the platform retains the record.
  6. Mass-market platform listing. A producer lists cottage food on Etsy or Amazon Handmade and accepts orders nationally. Same problem, scaled up. Some producers solve this by setting "ship to California only" filters; others by moving production to a commercial kitchen.
  7. Lapsed food handler card. The card is valid for three years, the lapse is silent, and the producer only discovers it when a market organizer asks for proof. Set a renewal reminder for 30 days before the expiration date.

A simple records system that satisfies an inspector

Records do not need to be elaborate. They need to be available. A producer with a clear set of files can satisfy an inspector in fifteen minutes; a producer without can spend weeks reconstructing what they should have saved.

The minimum file set:

File Contents Retention
Cottage food registration or permit Current county-issued document with the registration or permit number Until renewal completes
Food handler card Current accredited card Until three years post-expiration
Gross sales log Every sale, every venue, by date — total tracked against the current-year cap 4 years (matches CDTFA retention if you also have a seller permit)
Sales tax filings (where applicable) Quarterly returns and payment confirmations from CDTFA 4 years
Ingredient sourcing records Receipts and lot numbers for ingredients in pH-controlled and allergen-flagged products 2 years past shelf life of the product
Label samples At least one sample of each label version used during the year 2 years
Indirect-sale records (Class B only) Retailer name, invoice records, batch/production codes 4 years
Customer complaints, if any Date, customer, product, complaint, resolution Indefinitely

A spreadsheet works. A binder works. Software made for inventory and recipe-tracking works better, especially when the same ingredient lot, batch number, and label flow into a sales record automatically — that integration is the difference between fifteen minutes of inspector time and three frantic hours.

This is where Ardent Seller fits for cottage food producers who are tired of chasing the records. Ingredient lots flow into batches, batches into finished items, finished items into sales — and a single dashboard widget shows gross revenue against the current-year cap in real time. Recipe scaling, allergen detection, and label-ready ingredient statements are part of the same system. See features or pricing — the free tier covers most cottage food producers, and the recipe and batch tools are not premium-gated.

Q: Can I bake out of a rented kitchen and still register as a cottage food operator?

A: No. The cottage food rule requires production in your private home kitchen. A rented commercial kitchen, a community kitchen, a church kitchen, or a separate detached structure on the property is not a "home kitchen" for cottage food purposes. Production in any of those facilities pushes you out of cottage food and into commercial-kitchen jurisdiction.

Q: My friend wants to help me bake. Can I hire her?

A: No outside help. Cottage food production is limited to the operator and members of the operator's household. Hiring a friend or paying a contractor to help in the kitchen is not permitted. A spouse, partner, parent, or child living in the household can help; anyone outside the household cannot.

Q: Can I make my products in a commercial-grade home kitchen with extra ovens and equipment?

A: Yes. There is no rule against upgrading your home kitchen with commercial-grade equipment. The rule is about who uses the kitchen and where the kitchen is, not about what equipment is in it. Many cottage food operators run double ovens, commercial mixers, and chest freezers without leaving the cottage food exemption.

Q: Do I need a separate kitchen from where I cook for my family?

A: No. The same kitchen used for family meals can be used for cottage food production. The Class B inspection looks for sanitation and basic separation (pets out of the production area, food-grade surfaces, hand-washing facilities), not a dedicated commercial space. Time-separation between family cooking and production is the practical norm.

Q: Can I label my products as "organic" if my ingredients are organic?

A: Only with care. The "organic" label is regulated separately by the USDA's National Organic Program (NOP) and the California Department of Food and Agriculture's State Organic Program. To use the word "organic" on the label, you typically need certification or to qualify for the small-producer exemption — operations with under $5,000 in annual gross organic sales are exempt from certification under 7 CFR §205.101 but must still comply with NOP production and labeling standards. "Made with organic ingredients" claims have separate rules. When in doubt, drop the claim — false organic labeling carries penalties that dwarf cottage food enforcement.

Q: My county is not opt-in for MEHKO. Can I petition them to opt in?

A: Yes — but the path runs through your county Board of Supervisors, not the state. AB 626 makes opt-in a county-level decision. Producer advocacy groups in California have organized successful petitions in several counties; the COOK Alliance has been the most active organizer and maintains a county-by-county tracker. If MEHKO would change your business and your county has not opted in, this is a real lever.

Q: Can I sell at a wedding or a private party?

A: Direct sales to a buyer at a wedding or private party — where the host or planner is the customer — fit cottage food rules. Selling individual portions to guests at the event approaches the line because the host is typically the legal customer; if you sell directly to guests, you are operating as a vendor at a temporary food event, which has its own permit requirements. The cleaner path is to sell to the host as a single transaction, with delivery to the venue.

California cottage food law is a living document. The legislature has revised it most sessions since 2013, and CDPH and county offices update implementing rules accordingly. The primary sources every producer should bookmark:

  • California Health and Safety Code §113758 and §114365 et seq. — the underlying statute, available through the California Legislative Information portal.
  • CDPH Cottage Food Operations page — the agency page with current FAQ, the food list, and county contact links. Available at cdph.ca.gov.
  • Your county environmental health department — the actual office that processes your registration, runs your inspection (Class B), and handles complaints. Search "[your county] environmental health cottage food" to land on the right page.
  • CDPH MEHKO page — for hot/perishable food producers and to check county opt-in status.

Anything you read on a blog (this one included) is a snapshot of the rule on a specific date. Caps move, the food list expands, and the MEHKO opt-in list grows session by session. Before you commit to a production decision that depends on a specific number, verify against those sources.

If your goal is a side income from sourdough or a meaningful business from preserves, the California rule is workable, well-defined, and clearer than its reputation suggests — once you accept the two-class system and the county-by-county administration. The producers who succeed under it are the ones who treat documentation as part of the work, not an afterthought. Build the records as you build the product, and the inspector at the door is a fifteen-minute conversation.

Note on data freshness: California cottage food and MEHKO rules are revised by the legislature in roughly every other session. The $75K / $150K cottage food caps and the 30-meals/day, 90-meals/week, $100K MEHKO caps described here reflect the law as of early 2026. Both are subject to annual CPI adjustment, and the MEHKO opt-in county list grows over time. Verify against the CDPH page, the COOK Alliance tracker, and your county environmental health office before relying on any specific figure or county-level fact. Composite scenarios, named personas, and percentage examples in this guide are illustrative; cap-usage percentages use the statutory base figure for arithmetic clarity (the actual current-year line will be slightly higher because of the CPI adjustment).
