California packaged foods batching: commercial transition

What to take away

For California packaged foods batching, moving beyond cottage production starts with the product and process, which determine whether a shared kitchen, dedicated facility or co-packer fits. County permits, state registration and federal requirements may then shape the move.

What California cottage food operations may and may not sell

The California cottage food law, the California Homemade Food Act (AB 1616), lets a resident make certain low-risk foods in a private home kitchen and sell them without a commercial license. The permitted list is product-based, not size-based. Jams, jellies, dried fruit, granola and shelf-stable baked goods sit inside it, along with candy and honey.

Sales channels are restricted, and they decide the class. A Class A cottage operation may sell only directly to consumers. A Class B operation may also sell indirectly through a permitted third-party outlet such as a retail store or restaurant that resells the product.

A producer considering commercial production should treat Class B sales authority and commercial-facility requirements as separate questions, and confirm the applicable path with county environmental health.

Foods that need refrigeration to stay safe sit outside the cottage list, so meat, dairy-based fillings and cream pies cannot be made under it. Prepared meals are a different category again: AB 626 lets counties and cities that opt in permit Microenterprise Home Kitchen Operations, which follow their own rules and are not a route to packaged, batched goods.

Registration or a permit from the county is still required: a Class A operation registers with county environmental health, and a Class B operation needs a county permit, which brings an inspection. Fees are set county by county. In Sacramento County's cottage food program, for example, a Class A initial registration and its renewal are each $306.00, a Class B initial permit and its renewal, both including the home inspection, are each $528.00, and each submittal of additional products or labels for review costs $120.00. The same page notes that the California Homemade Food Act became effective on January 1, 2013, that permits are issued by the county in which the food is made and sold, and that moving from Class A to Class B, or to a new address, needs a new permit. The label must carry the producer's name, the county of production, and a statement that the food was made in a home kitchen not inspected by the health department. That statement follows the product to every shelf.

There is no quiet middle ground. You cannot batch at home and present the product as coming from a commercial facility, add a refrigerated item to the line and stay registered, or ship across state lines. Each of those moves the operation into a different regulatory category with different fees, inspections and facility standards.

Most producers hit the ceiling one of three ways: a retailer wants volume the home kitchen cannot supply, a new product needs refrigeration, or an order arrives from a neighboring state. Any one of those is the signal to start licensing work rather than stretch the registration.

Our licences and obligations guide maps the categories a producer moves between.

Moving from a home kitchen to a licensed commercial kitchen

A licensed commercial kitchen meets California retail food code construction and sanitation standards and holds the permits to operate. You have three routes: build out a dedicated space, rent hours in a shared or incubator kitchen, or contract with a co-packer. Each changes your cost structure and your control over the batch.

A shared kitchen is the cheapest entry. You rent hours, use inspected equipment, and hold your own permits for what you make there. The trade-off is scheduling, and the fact that a sanitation problem elsewhere under the same roof can interrupt your production. Incubator kitchens in California often bundle business counseling with the rental.

A dedicated buildout gives you control and costs the most. You own these items:

Whichever route you take, the sequence is the same.

Decide the product and process first, because the equipment and the plan check follow from it. Our compliance checklist for new owners walks the same sequence in more detail, including the documents counties typically ask for at plan check.

California state food safety and inspection requirements for scaling batchers

The California Department of Food and Agriculture runs a large share of the state's food safety work through its Animal Health and Food Safety Services Division, which handles food safety oversight for California food makers alongside its animal health duties. Past cottage registration, that division and its inspection programs become part of your compliance picture.

California requirements depend on the product category and the agency with jurisdiction. CDFA's inspection service laws and regulations apply to its inspection programs, not as a general rulebook for every packaged-food facility. For covered processed-food operations, confirm CDPH registration and applicable county requirements before designing the process.

Where state inspection applies, an inspector looks at process flow, sanitation procedures, water supply, pest control records and traceability. If your product requires a food safety plan, the inspector asks for it and for the records showing you followed it. Records are where small producers fail most often, not equipment.

Federal requirements do not replace applicable California or county requirements. Current Good Manufacturing Practice and the FDA's FSMA preventive-controls requirements for human food are in 21 CFR Part 117. Part 117 includes exemptions and modified requirements, including provisions for qualified facilities; some facilities subject to other FDA food-safety rules, such as seafood or juice HACCP, have different requirements. FDA Food Facility Registration is a separate requirement for facilities that manufacture, process, pack or hold food for consumption in the United States, subject to applicable exemptions.

A California producer selling only within the state may still have federal requirements, depending on the activity and any applicable exemption. Confirm your status rather than assume it.

The CDFA regulations activities page tracks how the state's regulatory activity changes over time, and is worth checking before a major process change. ServSafe certification for at least one person on site is a common expectation and a useful credential with buyers.

County health permits, plan checks and processing facility registration

Where a county food-facility permit is required, county environmental health handles permitting, plan review and inspections. California Retail Food Code provisions in Health and Safety Code sections 114380, 114381 and 114390 address plan review, operating permits and inspections. Requirements, fees and inspection intervals vary by county, so ask whether your operation falls under the county's program or a state registration.

Plan check comes before the permit. You submit floor plans, equipment specifications, a product list and often a process flow diagram. The plan checker reviews the design against the retail food code and returns comments. Build only after the plans are approved, because changes after construction are expensive and slow.

Processing facility registration is a separate question. California's Processed Food Registration (PFR), administered by CDPH's Food and Drug Branch, is distinct from a county health permit. Whether PFR applies depends on the product and activity, so confirm with the state program and county before starting. The first inspection is included in the initial PFR payment; a facility that fails it goes through a re-inspection, which is charged separately. Depending on what you make and how you sell it, PFR may apply rather than, or in addition to, a county permit.

Products with a history of state-level regulation, and certain low-acid or acidified foods, tend to fall here. Ask the county and the state program directly, in writing, and keep the answer in your files.

Batch controls for acidified foods once you scale

Batching becomes a technical question the moment a product leaves the cottage list for a pickled or acidified line. The federal rule is 21 CFR Part 114 on acidified foods, and it sets the controls a batch has to pass:

That list is why a batch sheet matters more than equipment: an inspector reads the pH log, the lot code and the scheduled process together.

A pre-opening inspection follows the buildout. The inspector confirms the approved plans were followed, equipment works, hot and cold water are available, and written procedures exist. Then the permit issues. Routine inspections continue after that, and a poor score can cost you retail accounts.

The permit file is also a sales document. Retail buyers and distributors ask for your county health permit number, business license and often proof of insurance. Having the file complete before the first buyer call saves a week of back and forth.

Our how to start specialty food business article covers the business registration side that runs alongside the health permit.

Weights and measures and labelling duties as volume grows

County sealers of weights and measures enforce California weights and measures rules under state law, and they apply to any packaged product you sell by weight or volume. Every package needs an accurate net quantity declaration. CDFA's summary of package labeling requirements describes the regulations California adopted under the Fair Packaging and Labeling Act for packages in general, and points to the California Code of Regulations, Title 4, for the complete requirements. Scales used for commerce must be approved and tested, and the county sealer inspects them.

Overstating net weight is the practical failure. If your jar says 12 ounces and the fill drifts to 11.6, you have a short-weight problem regardless of intent.

Set a fill target with a tolerance above the declared weight, check it on a schedule, and keep the records. This is the single most common weights and measures finding for small food producers.

Labelling duties grow with the channel. A farmers market label and a retail label are not the same document.

Nutrition facts are required in most cases, with limited exemptions for small businesses that qualify.

If you make a claim such as organic, gluten free or no sugar added, the claim must meet the standard behind it. California enforces federal labelling rules for most of these and adds its own requirements for some products. Proposition 65 warnings may also apply where a listed substance is present above the safe harbor level.

As volume grows, so does the cost of a recall or a mislabel. Build a label review step into every new product and every reformulation, and keep the approved artwork, ingredient spec sheets and nutrition panel calculation together so a buyer's question or an inspector's request takes minutes rather than days.

Our equipment checklist for new owners covers the fillers, scales and sealers that make consistent net weight achievable.

Financing a commercial kitchen buildout with SBA loans and counseling

A commercial kitchen buildout in California is a capital project, and the money question usually decides the timeline. The 7(a) loan program is the standard tool for this kind of financing.

It is a partially backed loan from a participating lender, usable for equipment, leasehold improvements, working capital and some closing costs.

Terms and rates are set by the lender within SBA limits, so the same request can produce different offers.

Prepare the file before you talk to a lender: a business plan with product and volume assumptions, a use-of-funds breakdown, projections, personal financial statements, and your licensing status. Lenders lend against a credible plan, not a recipe. If the plan depends on a shared kitchen first and a buildout later, say so and show the sequence.

SBA-backed counseling is free through the agency's resource partners, including Small Business Development Centers and SCORE. Use it for the plan review and the projections, not just the loan application. A counselor who has seen food businesses catches the omissions that slow an application, such as missing lease terms or an unconfirmed permit path.

Other sources worth checking include county and city economic development programs, food business incubators offering below-market kitchen rental, and equipment financing from suppliers. Some California incubators pair space with a small loan or a revenue-share arrangement. Compare the total cost, not the headline rate.

Keep the buildout scoped to what your permits and your first year of sales require. Producers routinely overspend on capacity they cannot fill, then run short on working capital when retail accounts slow to pay.

Our startup costs and funding options article breaks the first-year cost structure into facility, equipment, compliance and working capital lines. Fund the compliance line first, because it gates everything else.

Common questions

Can I sell cottage food across state lines from California?

No. The California cottage food law permits sales within the state only. Shipping to another state moves the product out of the cottage category and into a different regulatory framework.

Do I need a county health permit if I rent a shared commercial kitchen?

Yes, in most cases. You hold your own permit for the products you make, even though the facility itself is permitted separately. Confirm the arrangement with the county before you sign a rental agreement.

What is processing facility registration and does it apply to me?

It is the California Department of Public Health's Processed Food Registration (PFR), a state registration for food manufacturing, processing and storage, separate from a county health permit. Whether it applies depends on your product and process, so get a written answer from the state program and the county.

When do weights and measures rules start applying to my packages?

As soon as you sell a packaged product by weight or volume, including at a farmers market. The net quantity on the label must be accurate, and the scales you use for commerce must be approved and inspected.

Can an SBA 7(a) loan pay for a kitchen buildout?

It can cover equipment, leasehold improvements and working capital, subject to lender approval and SBA limits. Terms come from the lender, so compare offers rather than accepting the first one.

How long does it take to move from a home kitchen to a licensed facility?

It depends on the county, the buildout and the funding. Plan check and construction usually drive the timeline, and a shared kitchen can cut months off a dedicated buildout.
