Everything you need to get legally set up — from your Food Worker Card to the WSDA cottage food permit — with costs, timelines, and direct application links.
Washington has one of the more thorough cottage food permitting processes in the country. Unlike states that only require a simple registration or self-certification, Washington requires a kitchen inspection, recipe review, label pre-approval, and multiple supporting documents before your permit is issued. It takes more upfront effort — but once approved, you have a clear legal framework for operating your business.

Every person who will be involved in preparing cottage food products must complete the Washington State Food Worker Card training and exam. The only authorized online course is at foodworkercard.wa.gov — no other online courses are accepted. The course covers food safety fundamentals, costs $10, and can be completed in about 1–2 hours.
Apply for a Washington Master Business License through the Department of Revenue. This gives you a Unified Business Identifier (UBI) number and registers your business with multiple state agencies in one step. You'll need a copy of this license for your cottage food permit application. Apply online at dor.wa.gov.
Before investing in the WSDA application, confirm with your city or county that home-based food production is allowed in your zone. Some municipalities restrict or ban commercial food production in residential areas. Many cities also require their own business license endorsement — fees vary by location.
The WSDA cottage food permit application requires substantial documentation. Gather these items before you start:
A floor plan of your kitchen. Production process documentation for each product (recipes in WSDA's required format). An equipment and utensil list. A cleaning and sanitation plan. Processing dates and sales plan. A child and pet management plan. An example label for each product. Signed copies of Food Worker Cards for all persons on the application. A copy of your business license. Documentation that your kitchen is connected to an approved water source. You can submit up to 50 master products with variations.
Submit your complete application with all supporting documents and the $355 permit fee to WSDA. The fee covers the $125 inspection fee, $75 public health review fee, $30 processing fee, and other administrative costs. Apply through the WSDA Cottage Food Program page.
WSDA will review every recipe and label you submitted to confirm they meet the nonpotentially hazardous standard and labeling requirements. They may contact you with questions or request adjustments to your formulations or labels. This review happens before your kitchen inspection is scheduled.
Once your recipes and labels are approved, WSDA schedules an on-site inspection of your home kitchen. The inspector will verify your kitchen setup, water source, storage, cleanliness, and compliance with your submitted plans. If the inspection is unsatisfactory, you'll need to correct the issues and pay an additional $125 re-inspection fee.
After passing inspection, WSDA issues your cottage food permit with a unique permit number. This number goes on every product label. You're now legally authorized to produce and sell cottage food products in Washington — within the program's rules for allowed products, sales channels, and the $35,000 annual cap.
Washington requires an on-site kitchen inspection before your permit is issued — this is not optional. A WSDA inspector (or a local health department inspector under contract with WSDA) visits your home to verify that your kitchen meets the standards outlined in your application. They're checking that your kitchen is clean and well-maintained, that you have adequate handwashing facilities, that your water source is approved, that storage areas are protected from contamination and pests, and that your kitchen setup matches the floor plan and equipment list you submitted.
The inspection also verifies that you have a workable plan for keeping children and pets out of the kitchen during production, and that your sanitation procedures are realistic and in place.
Washington's state-level cottage food permit doesn't override local regulations. Your city or county may have additional requirements that apply to home-based food businesses:
Zoning compliance is the most critical local check. Some residential zones prohibit or restrict commercial food production. If your area doesn't allow home-based food businesses, you won't be able to use your cottage food permit there — regardless of WSDA approval. Contact your local planning or zoning office before investing in the permit process.
City business licenses are required in many Washington cities as a separate endorsement on top of the state Master Business License. Fees vary widely — some cities charge a flat annual fee while others base it on revenue. Check with your city's business licensing office.
County health departments administer the Food Worker Card program at the local level and may also conduct cottage food inspections under contract with WSDA. Your local health department is a good resource for questions about food safety requirements in your area.
Upload your permits, track renewal dates, and get automatic reminders before your cottage food permit or Food Worker Card expires.
