When Do You Need a Commercial Kitchen in Washington?

Many food businesses begin in a home kitchen.

That can be a practical place to test recipes, develop products, and learn what customers want.

However, not every food can legally be prepared at home for sale.

Whether you need a commercial kitchen depends on what you make, how it is stored, how it is sold, and which agency regulates the business.

You May Not Need One for Approved Cottage Foods

Washington’s Cottage Food Program allows certain foods to be prepared in a permitted domestic kitchen.

The program generally applies to shelf-stable products that do not require refrigeration for safety.

Examples may include:

• Cookies
• Bread
• Certain cakes
• Candy
• Granola
• Dry herbs
• Tea blends
• Seasoning blends
• Approved jams and jellies
• Dry baking mixes

You still need the appropriate permit.

Preparing food at home does not automatically make the business legal.

Refrigerated Foods Usually Need Approved Space

Foods requiring refrigeration are generally outside the standard cottage food program.

These products may include:

• Cheesecake
• Cream-filled pastries
• Custard pies
• Meat dishes
• Seafood products
• Dairy-based sauces
• Prepared meals
• Refrigerated salsa
• Cut fruits and vegetables
• Foods containing cooked rice or pasta

These foods can support bacterial growth when they are not prepared, cooled, stored, and transported correctly.

An approved commercial kitchen provides the equipment and controlled environment needed to manage those risks.

Restaurants and Caterers Need Approved Facilities

Restaurants, caterers, coffee shops, food trucks, and businesses serving prepared meals generally need to work with their local health department.

The kitchen must be approved for the type of food being prepared.

A bakery kitchen may not automatically meet the requirements for:

• Catering
• Raw meat preparation
• Large-scale cooling
• Seafood preparation
• Meal delivery
• Mobile food service

The local health department may review the kitchen layout, equipment, menu, storage, plumbing, food flow, and sanitation procedures.

Wholesale Production May Require Commercial Space

Direct-to-consumer sales are different from wholesale sales.

Wholesale includes selling products to:

• Grocery stores
• Restaurants
• Coffee shops
• Specialty markets
• Distributors

Even a shelf-stable product may need commercial production if it does not qualify for cottage food licensing or is sold through wholesale channels.

Be specific when speaking with regulators.

Explain whether products will be sold at markets, online, through local delivery, in stores, or to restaurants.

What Counts as a Commercial Kitchen?

A commercial kitchen is not simply a large or clean residential kitchen.

It is a food-production facility approved by the appropriate regulatory authority.

Requirements may include:

• Smooth and washable floors and walls
• Approved food-contact surfaces
• Dedicated handwashing sinks
• Dishwashing equipment
• Hot and cold running water
• Commercial refrigeration
• Dry storage
• Pest prevention
• Ventilation
• Waste disposal
• Adequate lighting
• Separation from personal belongings

Requirements depend on the operation.

A business producing packaged cookies may have different needs from one preparing meals or handling raw seafood.

Can You Rent a Shared Kitchen?

Yes.

Shared commercial kitchens can be useful for new businesses that are not ready to lease a permanent facility.

They may offer:

• Ovens
• Prep tables
• Refrigeration
• Freezer space
• Dry storage
• Dishwashing areas
• Cooking equipment
• Hourly rental
• A production address

Before signing an agreement, ask:

• Is the kitchen approved for my product?
• Do I need my own permit?
• Is storage included?
• Can I receive deliveries there?
• Can the address be used on labels?
• Is refrigeration included?
• Are cleaning fees separate?
• Does the facility allow wholesale production?

The kitchen’s license does not necessarily approve every renter to make every type of product.

Do Not Sign a Lease Too Early

One of the most expensive mistakes is leasing a space before confirming that it can be approved.

A kitchen may appear suitable but still have problems involving:

• Plumbing
• Ventilation
• Grease disposal
• Refrigeration
• Wastewater
• Zoning
• Handwashing sinks
• Equipment placement
• Food storage
• Restrooms

Correcting those problems after signing a lease can be expensive.

Prepare a description of your menu, ingredients, process, equipment, packaging, storage, sales methods, and expected production volume.

Use that information when speaking with the appropriate agency.

Consider the Full Cost

Kitchen rent is not the only expense.

You may also pay for:

• Storage
• Refrigeration
• Cleaning
• Waste disposal
• Insurance
• Security deposits
• Equipment use
• Scheduling fees
• Delivery access
• Additional permits

Calculate how many hours you realistically need for preparation, cooking, cooling, packaging, and cleanup.

A lower hourly rate may not be cheaper when storage and equipment are billed separately.

The Bottom Line

You may be able to prepare approved shelf-stable products in a permitted home kitchen.

You will generally need approved commercial space when producing refrigerated foods, serving prepared meals, catering, handling higher-risk ingredients, or manufacturing for wholesale distribution.

Confirm the requirements before renting space, buying equipment, or printing packaging.
