1. Shape the idea

  1. Describe the food and the experience. Write down your concept, draft menu, how you expect to prepare and serve it, and who you hope to serve.

  2. Make a first operating sketch. Note whether you are exploring a truck or trailer, the equipment you expect to use, and the neighborhoods or event settings you are considering.

  3. Start a questions list. Keep unknowns visible. Mark anything that depends on your specific operation for direct follow-up with an agency or qualified adviser.

2. Find the right agency starting points

  1. Ask Public Health — Seattle & King County what to confirm. Find the current mobile-food permit and plan-review information, then write down the questions that match your food, unit and operating plan. Official starting page checked November 1, 2026: King County mobile food business permits.

  2. Ask the City of Seattle about your proposed locations. Use the City's mobile-food guide to identify location and business questions to verify for each place you may operate. Official starting page checked November 1, 2026: City of Seattle mobile food vending.

  3. Ask Seattle Fire what applies to your equipment. Record questions about your planned fuel and cooking setup and follow the current Fire Department information for your unit. Official starting page checked November 1, 2026: Seattle Fire Department permits.

3. Plan before committing money

  1. Compare vehicle options. List the trade-offs you want to investigate for a new or used truck and a truck or trailer. Ask a qualified inspector to review a used unit before you commit.

  2. Draft a startup and operating budget. Gather current quotes for the vehicle, build-out, equipment, insurance, supplies, agency costs and opening reserve. Keep estimates separate from confirmed costs.

  3. Cost the menu you actually plan to serve. Estimate ingredient quantities, portion size, sale price and preparation time using your own current supplier quotes.

4. Prepare for launch

  1. Recheck the open questions. Confirm current approvals and operating details directly with the agencies for your menu, vehicle, equipment and locations before opening.

  2. Make a first-week plan. Check your business name, plan your Google Business Profile and social setup, and outline the updates and tasks for opening week.

  3. Choose the next decision and owner. Write down the action, who will do it, what source or quote is needed, and when you will revisit it.

Needs human review: If sources conflict or an answer depends on your exact operation, mark it for follow-up and ask the agency directly. This checklist does not resolve those questions.
