Wisconsin Cottage Food Law: What Home Sellers Can and Cannot Do in 2026
Wisconsin Doesn't Have a Cottage Food Law — Not Really
Most states pass a single cottage food statute that spells out what home producers can sell, how much they can earn, and where they can do business. Wisconsin took a different path. Instead of one coherent law, the state operates under a patchwork of a court injunction from 2017, a narrow canning statute from 2010, and the Wisconsin Supreme Court's 2025 denial of review that left unbaked foods outside the home-production exemption.
The result is a system where you can legally sell chocolate chip cookies from your living room without a license or revenue cap, but producing a chocolate bar in the same kitchen is a misdemeanor carrying up to $1,000 in fines and six months in jail.
Understanding which channel your product falls into — and which rules apply — is the single most important step before you spend a dollar on ingredients or packaging.
The Kivirist Exemption: Oven-Baked Goods Without a License
The foundation of home baking in Wisconsin is Kivirist v. DATCP (Lafayette County Case No. 2016CV06), decided in 2017. Judge Duane Jorgenson ruled that the state's ban on selling home-baked goods was unconstitutional. A 2021 clarification expanded the ruling to cover any shelf-stable product baked in an oven — not just flour-based items.
To qualify, your product must meet four criteria:
- Oven exposure — dry heat above 140°F in a closed chamber (oven, waffle maker, Dutch oven). Dehydrators don't count
- Non-potentially hazardous — the finished product must be shelf-stable with water activity at or below 0.85
- Direct-to-consumer only — no wholesale, no retail consignment, no restaurant supply
- In-state sales — all transactions must happen within Wisconsin
If your product checks every box, there is no license requirement, no registration with DATCP, and no annual sales cap. You can sell at farmers markets, through home pickup, local delivery, and even in-state online pre-orders.
The Pickle Bill: Canned Goods Under Tight Limits
The statutory side of Wisconsin's home food framework is the Pickle Bill (Wis. Stat. § 97.29(2)(b)2), enacted in 2010. It allows unlicensed production and sale of home-canned, high-acid foods — but with severe restrictions compared to the baking exemption.
Your canned product must be a naturally acidic or acidified fruit or vegetable with an equilibrium pH of 4.6 or lower. Jams, jellies, pickled vegetables, sauerkraut, kimchi, and applesauce qualify. Pickled eggs, pesto, lemon curd, meat products, and anything with a pH above 4.6 do not.
The Pickle Bill imposes a hard gross revenue limit of less than $5,000 per person per year. Sales are limited to farmers markets, flea markets, and community events — you cannot sell canned goods from your home, online, or through mail delivery.

What's Banned: The Unbaked Food Ruling
The Wisconsin Cottage Food Association spent years in court trying to extend the Kivirist baking exemption to unbaked shelf-stable items like chocolate, fudge, dry mixes, and roasted coffee beans. A circuit court initially agreed in December 2022, but the Wisconsin Court of Appeals reversed that decision in November 2024 (2024 WI App 69). The Wisconsin Supreme Court denied review in April 2025, making the ban permanent.
This means chocolate bars, caramels, fudge, no-bake cookies, dry soup mixes, trail mixes, raw granola bars, energy bars, chocolate-dipped confections without an oven-baked base, and roasted coffee beans are all illegal to produce and sell from a home kitchen. The only legal path for these products is a licensed commercial facility.
During the 2025–2026 legislative session, Assembly Bill 748 and Senate Bill 739 attempted to create a unified cottage food framework with a $40,000 sales cap and registration system. Both bills failed on March 23, 2026. The fragmented status quo remains in effect.
Quick Reference: What's Legal From a Wisconsin Home Kitchen
| Category | Legal from home? | Cap | Where you can sell |
|---|---|---|---|
| Oven-baked shelf-stable goods | Yes (Kivirist) | No cap | Home pickup, delivery, farmers markets, in-state online |
| High-acid canned fruits/vegetables (pH ≤ 4.6) | Yes (Pickle Bill) | Less than $5,000/year per person | Farmers markets, flea markets, and community events only |
| Unbaked shelf-stable foods (chocolate, fudge, dry mixes) | No | N/A | Commercial kitchen only |
| Refrigerated or TCS foods | No | N/A | Commercial kitchen only |
What This Means for Your Business
The gap between what feels like it should be legal and what actually is legal in Wisconsin catches people constantly. A granola bar baked in the oven at 350°F is fine. The same granola pressed together without baking requires a commercial license. Buttercream frosting made with powdered sugar and shortening is likely safe, but a cream cheese frosting could push your water activity above 0.85 and disqualify your entire product.
Before you invest in equipment, packaging, or a farmers market booth, you need to classify every product in your lineup against Wisconsin's specific rules — not generic cottage food advice from other states.
