How do I get my hot sauce approved as an Arizona cottage food?

Arizona is one of the more open states for a home sauce maker. The Arizona Department of Health Services cottage food program now counts acidified foods and fermentation among the "special processes" it allows, and a registrant can have a product approved as shelf stable by emailing lab results showing a pH of 4.6 or below or a water activity below 0.85 [1]. That lab result is the condition that matters: without it your sauce is treated as perishable and can only be sold by you, in person. With it, a shelf-stable sauce can ship within Arizona, go through a third party and even be sold wholesale [1]. Every sale stays inside Arizona: the current cottage food rule, R9-8-101.02, limits sale and delivery to the state [2]. Registration is free and is renewed every three years [1] [2].

Getting shelf-stable approval for a sauce

The ADHS program presentation lays out the pieces in this order [1]:

1. Get a food handler training certificate. A current Food Handler Training Certificate of Completion is required to apply.
2. Register with ADHS. The application asks for your contact information, the physical address of your home kitchen and your acknowledgment of the program policies. There is no annual program fee, and registration is renewed every three years [2].
3. Have each sauce tested by a lab. For pH, the result must be 4.6 or below. For water activity, it must be below 0.85. ADHS lists contact information for two University of Arizona testing labs.
4. Email the results to ADHS to have that product approved as shelf stable.
5. Make every batch in your home kitchen. All processing must happen there.

The presentation does not say whether one test covers a recipe for good or whether ADHS wants a retest after a recipe change. Assume a changed recipe is a new product and ask before selling it. For a vinegar hot sauce, pH is the measure that applies; water activity matters mostly for very thick pastes and dried products, as the water activity page explains. The testing labs page covers what to ask a lab for. A lab number at the moment of testing is not the same as a validated process, so measure your own batches as well.

What approval opens up

Wholesale is the striking part. Most cottage food laws keep you out of stores; Arizona lets an approved shelf-stable product be sold through others, provided it stays in the package you sealed [1]. A shop that sells it must keep it in a separate section or display case, with a sign saying the product is homemade and exempt from state licensing and inspection [2]. Before a store takes your sauce, it may ask for things the state does not, such as product liability insurance; the getting into stores page covers what buyers expect.

Fermentation as a special process

Fermentation is on the ADHS list of permitted special processes, and a fermented product goes through the same lab route to shelf-stable approval [1]. ADHS does not distinguish a ferment finished with vinegar from one that reaches its pH by fermentation alone. This book treats a ferment with added acid as an acidified food unless a process authority rules otherwise in writing; in Arizona both kinds need the same lab result, so test the finished, bottled sauce rather than the mash. The fermented sauce page explains why the distinction matters once you sell outside the cottage program.

Production date, registration number and the allergen line

Each label carries the production date, your name and registration number, and a complete ingredient list that includes the components of compound ingredients [1]. It also carries the statement the rule sets out word for word [2]: "This product was produced in a home kitchen that may come in contact with common FOOD allergens and pet allergens and is not subject to public health inspection." The rule adds a second required line: "To obtain additional information about cottage foods or to report a foodborne illness, go to azdhs.gov/Cottagefood" [2]. A developmental disability statement is required where it applies [1]. The federal elements are on the federal labeling page.

What the state source leaves open

The ADHS presentation carries no date and cites no statute, and neither it nor rule R9-8-101.02 states a sales cap [1] [2]. The rule settles the out-of-state question: sale and delivery are limited to Arizona [2]. Ask ADHS about anything else, such as how online orders must be filled. Selling across state lines would take you out of the cottage program and into federal acidified food rules that a state registration does not settle; the acidified foods page explains them. If your sauce outgrows the cottage program, ask ADHS or your county environmental health office which permit covers a commercial food processor; this page could not confirm the license name from a primary source.

Confirm with the Arizona Department of Health Services

The ADHS Cottage Food Program runs registration and shelf-stable approvals; its program presentation and rule R9-8-101.02 (February 28, 2025) are the official sources used here [1] [2]. This page was last verified October 2026. To see where Arizona sits among the states, read selling hot sauce in your state, and if you want a recipe reviewed before testing, see finding a process authority.
