How to Start a Class A Cottage Food Business in Wisconsin

Wisconsin has one of the most unique cottage food landscapes in the country. Thanks to a series of court rulings, bakers can sell unlimited amounts of baked goods from their home kitchens, while other cottage food producers face much stricter limits. If you're ready to turn your kitchen skills into income, here's exactly how to navigate Wisconsin's Class A cottage food laws.

What You'll Learn

This guide walks through Wisconsin's specific cottage food requirements, from understanding what you can legally sell to setting up your business structure. You'll get a clear roadmap for launching your cottage food operation without expensive permits or commercial kitchen requirements.

Understanding Wisconsin's Cottage Food Laws

Wisconsin's cottage food laws evolved through litigation rather than legislative updates, creating a unique situation. The state distinguishes between different types of cottage foods with varying sales limits and requirements.

Baked Goods: Unlimited Sales

Court rulings have established that baked goods can be sold without dollar limits. This includes:

• Breads and rolls
• Cakes and cupcakes
• Cookies and bars
• Pies and tarts
• Muffins and quick breads
• Pastries and donuts

The key requirement: these items must be shelf-stable at room temperature and not require refrigeration for safety.

High-Acid Canned Goods: $5,000 Annual Cap

Wisconsin allows sales of properly canned high-acid foods up to $5,000 per year, including:

• Fruit jams and jellies
• Pickled vegetables
• Fruit butters
• High-acid salsas
• Canned fruits

These products must follow tested recipes and proper canning procedures to ensure safety.

Restricted Products

Wisconsin is notably restrictive on other common cottage food items. You cannot sell:

• Fresh produce
• Meat or poultry products
• Dairy items
• Low-acid canned goods
• Fermented foods
• Items requiring refrigeration

Step-by-Step Setup Process

Step 1: Choose Your Product Focus

Decide whether you're primarily a baker (unlimited sales potential) or focusing on canned goods (capped at $5,000 annually). Most successful Wisconsin cottage food businesses focus heavily on baked goods given the sales freedom.

Consider your local market demand. Seasonal baked goods like holiday cookies, summer fruit pies using local ingredients, or weekly bread deliveries often perform well.

Step 2: Master Food Safety Requirements

Wisconsin requires cottage food operators to complete food safety training, though specific requirements can vary by county. Contact your local health department to understand their training expectations.

Common food safety courses that meet Wisconsin requirements include:

• ServSafe Food Handler certification
• County-specific cottage food training programs
• University of Wisconsin Extension food safety courses

Keep documentation of any training completed, as inspectors may request proof during routine checks.

Step 3: Set Up Your Kitchen

Your home kitchen becomes your legal production facility. Wisconsin doesn't require separate commercial equipment, but you must maintain food safety standards:

Essential equipment for most operations:

• Calibrated thermometers for ovens and food storage
• Separate cutting boards for different food types
• Adequate handwashing facilities
• Proper food storage containers
• Cleaning and sanitizing supplies

For canned goods specifically:

• Tested pressure canner or water bath canner
• Accurate pH testing strips or meter
• Proper canning jars and lids
• Timer for processing times

Document your equipment maintenance and calibration schedules, as health departments may review these during inspections.

Step 4: Understand Labeling Requirements

Wisconsin has specific labeling requirements for cottage food products. Every item must include:

• Product name
• Your name and address
• Ingredients list (in descending order by weight)
• Statement: "Made in a home kitchen that has not been inspected by a regulatory authority"
• Net weight or volume
• Date of production

For canned goods, add:

• "Keep refrigerated after opening" (if applicable)
• Specific storage instructions

Print labels on durable material that won't smudge or peel during normal handling. Many cottage food producers use waterproof label paper or laminated labels.

Step 5: Register Your Business

While Wisconsin doesn't require a specific cottage food permit, you'll need basic business registrations:

State level:

• Register your business name with Wisconsin Department of Financial Institutions (if using a business name different from your legal name)
• Obtain a Wisconsin tax ID number for sales tax collection

Local level:

• Check with your city or county for business license requirements
• Verify your residential zoning allows home-based food businesses
• Contact your homeowners insurance company about business coverage

Step 6: Set Up Sales Channels

Wisconsin allows both direct-to-consumer and online sales, but restricts wholesale to retail stores. You can sell through:

Direct sales:

• Farmers markets
• Community events
• Home delivery
• Customer pickup at your residence

Online sales:

• Your own website
• Social media platforms
• Online marketplaces that allow cottage food products

You cannot sell to restaurants, caterers, or other food service establishments under cottage food laws.

Step 7: Establish Record Keeping

Maintain detailed records of your cottage food business, including:

• All ingredient purchases with receipts
• Production logs with dates and quantities
• Sales records with customer information
• Any customer complaints or feedback
• Equipment maintenance logs

Wisconsin health departments may request these records during routine inspections or if investigating customer complaints.

Managing the $5,000 Limit for Canned Goods

If you're selling high-acid canned goods, tracking your annual sales against the $5,000 limit requires careful attention. Consider these strategies:

Month-by-month tracking: Set up a simple spreadsheet to monitor canned goods sales monthly, ensuring you don't exceed the annual cap unexpectedly during peak seasons.

Product mix strategy: Focus primarily on baked goods for regular income, using canned goods as seasonal specialties or value-added products that complement your baking.

Customer education: Help customers understand the difference between your unlimited baked goods and limited canned goods availability.

Common Pitfalls to Avoid

Assuming all preserved foods are allowed: Wisconsin's restrictions on fermented foods, low-acid items, and fresh products are stricter than many other states. Stick to clearly approved categories.

Mixing cottage food with other food handling: If you plan to serve food at events or offer catering services, those activities require separate permits and cannot be done under cottage food laws.

Inadequate record keeping: Wisconsin health departments take record keeping seriously. Poor documentation can lead to compliance issues even when your food safety practices are excellent.

Next Steps

Wisconsin's cottage food laws offer genuine business opportunities, especially for bakers who can take advantage of unlimited sales potential. Start with a focused product line, master the food safety and labeling requirements, and build your customer base gradually.
