How to start in King County
Permit, label, and local steps for selling under Washington cottage food rules in King County. Not legal advice.
Confirm your menu under state law
Washington cottage food rules control what you may make at home (Nonpotentially-hazardous baked goods; baked candies and stovetop candies; jams, jellies, preserves, and fruit butters (as defined in 21 C.F.R. §150); and other nonpotentially hazardous foods identified by the director by rule. No THC ingredients (0.3% or greater) permitted. No dollar sales cap is specified in the statute.). King County cannot expand a food the state bans.
Map channels and local sales rules
State sales cap: No cap. On-site / porch pickup in King County: Yes. Prefer markets or off-site pickup if residential customer traffic is restricted.
Local permits, tax, and home occupation
Home occupation permit: Conditional. Many places still need a general business license or tax certificate even when the state has no cottage food “permit.” Check planning, the clerk, and any HOA or lease before advertising your address.
Training, registration, inspection
State registration: Yes. Local inspection in King County: Yes. Finish food handler training early — markets often ask for a copy.
Labels that match the state
Print labels with Washington disclaimer and allergen rules before market day. Use the free Washington label page for the one-pager checklist and mockup.
Insurance and first sales
Farmers markets often require a certificate of insurance. Soft-launch with pre-orders, keep a sales log, and re-verify rules if you change products or venues.
What usually goes on the package
- Product name (common or usual name of the food)
- Business or producer name
- Producer address (or address alternative your state allows)
- Ingredients in descending order by weight
- Major allergen disclosures (e.g. wheat, milk, eggs, soy, tree nuts, peanuts, fish, shellfish, sesame)
- Net weight or quantity
- Home-kitchen disclaimer: “Made in a home kitchen that has not been subject to standard inspection criteria.”
Planning checklist only. Confirm with state and local agencies before you sell.
