Commercial Kitchen Requirements Michigan: Licensing, Costs, and Shared-Use Options

When a Home Kitchen Isn't Enough

Michigan's cottage food exemption lets you sell shelf-stable foods from your home kitchen with no license. But the exemption has hard boundaries, and crossing any of them means you need a commercial kitchen.

Three triggers force the transition:

Revenue. Your gross annual sales exceed $50,000 (or $75,000 if every product is priced at $250 or more per unit).

Product type. You want to sell foods that require refrigeration — cheesecakes, cream-filled pastries, pickled vegetables, salsas, dairy products, or anything classified as TCS (Time/Temperature Control for Safety).

Sales channel. You want to sell wholesale to grocery stores, place products on consignment in retail shops, supply restaurants, or ship across state lines.

Any one of these dissolves the cottage food exemption immediately.

Two Licensing Tracks

Michigan routes commercial food businesses through two different authorities depending on the business model:

MDARD (Michigan Department of Agriculture and Rural Development) licenses businesses that focus on wholesale distribution, manufacturing, internet shipping without pre-sale interaction, or processing shelf-stable acidified foods like hot sauces and pickles.

Local Health Department licenses businesses that sell directly to consumers for immediate consumption — retail bakeries, cafes, food trucks, and temporary food stands at events.

Both tracks require a licensed commercial kitchen, a plan review before opening, food manager certification, and ongoing inspections.

Physical Kitchen Requirements

A commercial kitchen in Michigan must meet specific infrastructure standards:

• Flooring and walls: Non-porous, smooth, easily cleanable surfaces. Commercial-grade tile, sealed concrete, or stainless steel panels. No residential carpeting, wood paneling, or textured drywall.
• Handwashing station: A dedicated handwashing sink separate from prep and ware-washing sinks, with hot and cold running water, soap, and paper towels.
• Three-compartment sink: For wash-rinse-sanitize cycles on all utensils and equipment.
• Commercial ventilation: A mechanical exhaust hood over cooking equipment, with grease filters meeting local fire code.
• Grease trap: Connected to the drainage system to prevent fats, oils, and grease from entering the municipal sewer.
• Commercial refrigeration and freezer units: Adequate cold storage with thermometer monitoring.
• Proper waste disposal: Separate trash and recycling areas, appropriate wastewater handling.

Building out a private commercial kitchen from scratch can cost $50,000 to $200,000+ depending on size and equipment. That's why shared-use kitchens exist.

Shared-Use and Incubator Kitchens

Renting time in a licensed shared-use or incubator kitchen is the most common path for cottage food operators scaling up. These facilities provide a fully licensed, inspected space at a fraction of the cost of building your own.

Michigan has several established options:

• Eastern Market Shed 5 Kitchen (Detroit)
• Downtown Market Grand Rapids incubator kitchen
• Allen Neighborhood Center (Lansing)
• Michigan Incubator Kitchen Network (MIKN) members across the state

Costs typically range from $200 to $1,000+ per month depending on hours needed, storage requirements, and facility amenities. Most shared kitchens require renters to provide:

• A valid food manager certification (ServSafe or equivalent)
• Detailed standard operating procedures for their products
• Proof of general and product liability insurance

Plan Review Process

Before opening any commercial food operation in Michigan, you must submit a plan review to either MDARD or your local health department (depending on your licensing track). The review evaluates your kitchen layout, equipment specifications, menu, water source, and waste disposal.

Plan review fees vary significantly by jurisdiction. A few examples from Michigan counties:

• Western UP District Health Department: $250–$650
• Livingston County: $1,300–$1,560
• Oakland County: integrated into the local building review program

MDARD charges a $197 plan review fee for state-licensed establishments.

Submit your plan review at least 30 days before you intend to open. The review must be approved before you begin production.

Annual Licensing Costs

Annual license fees for commercial food establishments also vary by county and business size:

• Small operations (0–25 seats or equivalent): $338–$680 per year
• Medium operations: $398–$810 per year
• Large operations: $458–$1,070 per year
• Mobile food units: $130–$290 per year
• Special Transitory Food Units (STFU): $172–$304 per year

These fees are on top of your kitchen rental or facility costs, insurance, and food manager certification.

Timing the Transition

Moving too early drains startup capital on overhead before the revenue is there. Moving too late risks an MDARD violation and product seizure. The practical approach: start monitoring your annual revenue when you hit 70% of the cottage food cap. At 80%, begin researching shared-use kitchen options, scheduling food manager certification, and budgeting for plan review fees.
