How to start a corporate catering business in Seattle
Start Seattle corporate catering with a bounded office cluster and an approved production kitchen, not a promise to cover the entire Puget Sound region.
Base startup economics
The general startup range for this model is $50K to $500K, with target margins of 10% to 25%. These are baseline figures, not city-specific quotes. Replace them with local rent, labor, insurance, permit, supplier, and utility estimates.
Demand in Seattle
Interview office buyers in one Seattle district about on-site attendance, meeting frequency, order sizes, and payment rules. Tourist dining guides do not establish workplace demand, and nearby employers do not guarantee daily orders.
Local operating realities
- Ask King County what approvals the catering operator needs when using a shared or commissary kitchen.
- Time loading, parking, building security, elevators, and wet-weather handovers as part of the delivery route.
- Keep drop-off lunches and staffed events as separate packages with explicit labor, equipment, and transport costs.
Local market validation
- Obtain paid trial orders from a small group of offices with compatible delivery windows.
- Rehearse temperature-controlled packing and kitchen-to-desk delivery under actual route conditions.
- Track reorders and contribution after delivery labor, packaging, and invoice delays before expanding.
How to get set up locally
Official-source research. Checked .
Jurisdiction: Fixed food premises in the City of Seattle. Public Health, Seattle & King County handles food approval; Seattle handles city business licensing and relevant site permits. This is not a statewide or whole-Puget-Sound checklist.
Permits and approval sequence
Check permitted use and the city's site approvals
Check the proposed restaurant or kitchen use with Seattle before committing to the site. Construction, plumbing, electrical, mechanical, fire protection, signs, and outdoor seating can require separate approvals. Ask which apply to the existing building and planned work; the food permit does not replace them.
Submit the menu and plans to King County
King County directs permanent food businesses to submit plans before construction, remodeling, or an ownership change. Use the current plan-review guide and Public Health Permit Center, including the menu, equipment and floor plans. Discuss any takeover exception with the reviewer rather than assuming the previous permit transfers.
Apply to operate and arrange the pre-operational inspection
After plan approval, submit the application to operate and pay the operating fee, which is separate from plan review. King County says to schedule the pre-operational inspection at least one week before opening. The operating permit is issued following a successful inspection; do not open while that approval is outstanding.
Complete city business licensing and food-worker requirements
For a food business based in Seattle, obtain the applicable Seattle business license tax certificate and renew annually. King County states that food-business employees must obtain Washington Food Worker Cards. Confirm any additional alcohol, specialized-processing, or catering requirements for the proposed activities.
Business-specific launch checklist
Atlas planning guidance, adapt to your menu and service model.
- Confirm the production kitchen's approval and your own operating permissions. Renting a licensed kitchen does not automatically settle the caterer's obligations.
- Design three office packages with portion sizes, dietary options, minimum orders, and clear cut-off times.
- Simulate delivery from packing through loading, building access, setup, and handover. Record hot and cold holding performance.
- Pilot recurring lunches with a small delivery zone, and calculate margin after drivers, disposables, overtime, and client payment delays.
Build your local budget
Keep plan review, the annual operating permit, city licensing, and construction or trade permits as separate budget lines. Request current fee calculations for the menu's risk level and quotes for plumbing, water heating, refrigeration, ventilation, insurance, labor, and delivery. Do not treat older handbook fee examples or review times as a current quote.
- Production kitchen rental and storage
- Insulated transport, holding equipment, and vehicle costs
- Packaging, setup labor, and dietary substitutions
- Insurance and working capital for invoiced orders
