Catering in Washington

Plan your event menu, preparation kitchen, food safety training and transport before accepting a catering booking.

Food prepared at your home and transported to an event is a different operation from low-risk home baking. Tell the authority where you cook, store and serve every part of the menu.
Hot holding, cooling, reheating and travel time matter for catered meals. Ask which equipment and event approvals apply before quoting the job.
Use a written event brief covering guest count, menu, allergies, venue, serving arrangements and payment terms. Confirm changes before production.

Plan your service

Review your menu and kitchen with the authority Confirm locally
Explain whether you will use a commercial kitchen, your home or the event venue. Do not assume the low-risk home-food exemption covers catering.
Confirm permits, training and inspection Confirm locally
Use the local application links below. Ask about the kitchen approval and certified staffing needed for your operation.
Plan transport and food service Confirm locally
Ask about temperature control, storage, water, handwashing and any venue or temporary-event requirements.
Agree on the booking details Recommended
Record the guest count, allergens, service time, venue responsibilities, deposit and cancellation terms.

State home food context in Washington

Cottage Food Operation Permit. Approved non-potentially hazardous foods produced in your primary residential kitchen.

Permits and kitchen approval

For catering, refrigerated meal prep or food cooked away from a client’s kitchen, ask the state or local food authority about the applicable food-service permit, preparation-kitchen approval, training and inspection. A cottage-food exemption alone does not approve the service.

Official resources: confirm your business route

These links cover home-food and licensed business routes. Low-risk home-food exemptions are context only for your service; ask the authority which applications apply.

Four different things people mix up

A certificate does not let you open. Each of these is its own step, and you may need more than one.

Food safety certificate
Proves you passed training. It does not approve your kitchen or business.
Food business permit
Authorizes a specific operation, where one is required.
Notification or registration
Telling the health authority you are operating. A separate process.
Business license
Your city’s home-occupation or business approval. Also separate.

Federal and business rules to check in the US

The details depend on your product and selling method. Check the applicable requirements and exemptions.

Labels and allergens
Check product identity, ingredients, major allergens including sesame, net quantity, producer details and your state’s home-kitchen disclosure. Check whether a nutrition-label exemption actually applies.
Selling across state lines
An online order does not automatically permit interstate shipping. Check the origin and destination rules plus FDA or USDA requirements. A private residence is not automatically an FDA-registered food facility.
Business setup and taxes
Check business structure, income and self-employment taxes, any EIN requirements, and state or local sales-tax registration. A cottage-food exemption is separate from tax obligations.
Local licenses and permits
Food permissions, home-occupation approval and business registration are separate. Use the SBA launch resources and your city or county to identify the applicable local process.

What sellers wish they knew

Home-food business
A commenter says their license/permit process took about eight weeks and that accepting a short starting product list was the most time-consuming decision. They describe beginning with roughly eight or nine master products and variants.
Practical takeaway: Prepare a small, manageable launch menu and allow time for approval. This is one operator's timeline, not an agency processing promise.
Keep in mind: This is a reported experience, not current legal requirements or typical earnings.

Private chef booking
A customer reports additional staffing/decor charges before a private-chef event and further expense requests afterward despite a stated agreed price. They describe unclear communication about what the service included.
Practical takeaway: Make groceries, staffing, tableware, decor, cleanup and payment terms explicit, and agree on a change-approval process before a booking.
Keep in mind: This is one customer’s account. The provider’s perspective and the dispute’s outcome are not established.
