Wisconsin Cottage Food Catering Rules: Can You Cater From a Home Kitchen?

The Short Answer: No

Wisconsin's home food exemptions do not cover catering. The Kivirist baking exemption and the Pickle Bill both allow specific products to be sold through specific channels. Neither one authorizes operating a catering service from your home kitchen.

Catering — preparing and serving food at a client's event or location — falls squarely under DATCP's Retail Food Establishment licensing requirements (Wisconsin Administrative Code ATCP 75). You need a commercial food license, a licensed kitchen facility, and a Certified Food Protection Manager.

There's no workaround, partial exemption, or gray area here. But the distinction between what's legal and what requires a license is worth understanding, because the line is narrower than most people think.

What Home Bakers Can Do

Under the Kivirist exemption, you can legally sell oven-baked, shelf-stable goods directly to a consumer who happens to be buying for an event. The key is what you're selling and how you're selling it.

Legal examples:

• A customer orders five dozen cookies for their daughter's graduation party. You bake them in your home kitchen, package and label them, and the customer picks them up or you deliver them. This is a direct-to-consumer sale of exempt baked goods — the fact that the cookies end up at a party doesn't change the transaction.
• A customer orders a custom decorated cake for a wedding. You bake it, decorate it (using only non-potentially hazardous, shelf-stable frostings and decorations), and deliver it. You're selling a product, not providing a service.

Where it crosses into catering:

• You set up a dessert table at the event, arrange the display, and serve guests. Now you're providing a food service, not selling a product.
• You prepare hot food, temperature-controlled items, or fresh items at the event location. This is food preparation and service, which requires a commercial license regardless of venue.
• You provide the food along with plates, utensils, napkins, and serving staff. This is a catering operation by any regulatory definition.

The distinction comes down to transaction type: selling a finished, packaged product to a consumer versus providing a food preparation and service operation at an event.

Catering Under the Pickle Bill

The Pickle Bill is even more restrictive. Home-canned high-acid foods can only be sold face-to-face at farmers markets, flea markets, or community or social events. Even if you wanted to provide jars of homemade jam as part of a catering spread, the Pickle Bill does not authorize a catering service; the sale must remain a direct-to-consumer sale at an allowed venue. And the $5,000 annual cap applies regardless.

What You Need to Cater Legally

If you want to operate an actual catering business in Wisconsin, the requirements are:

Retail Food Establishment License (ATCP 75): Apply through DATCP or your local agent health department (Public Health Madison & Dane County, City of Milwaukee, Brown County, or Waukesha County, depending on your location). Pre-inspection license fees range from $126 to $822 through DATCP, with annual renewal fees of $105 to $540.

Licensed kitchen facility: Your production kitchen must meet ATCP 75 infrastructure standards — commercial equipment, three-compartment warewashing sink, hands-free handwashing sink, non-porous surfaces, and a facility that's physically separated from residential living space. Home kitchens don't qualify unless they're built as a separate, dedicated space with distinct plumbing and entrances.

Certified Food Protection Manager: At least one person must hold a valid CFPM certification ($125–$175, valid for five years).

Business setup: LLC or DBA registration, federal EIN, Wisconsin Seller's Permit, and commercial liability insurance ($1,400–$2,400/year for standard catering coverage).

For many home bakers, the practical bridge is renting time at a shared-use commercial kitchen like FEED Kitchens in Madison or the Brown County Culinary Center at $12 to $18/hour. You get access to a licensed facility that satisfies ATCP 75 requirements without building your own space.

A Practical Middle Ground

Several home bakers in Wisconsin operate a dual model: they sell direct-to-consumer baked goods under the Kivirist exemption from their home kitchen (no license, no cap) while also renting shared kitchen time for any orders that cross into catering territory. The home kitchen handles the routine farmers market and custom order business. The shared kitchen handles event orders where the customer wants setup, service, or temperature-controlled items.

This split lets you maximize the low-overhead home exemption for the bulk of your business while keeping the catering option available through a licensed facility.
