Cottage Food Kitchen vs. Commercial Kitchen: When It's Time to Make the Jump

Most home food businesses hit the same wall. A café asks to carry your granola, and your state says cottage food cannot be resold. A regular wants a cheesecake, which needs refrigeration and in most states falls outside the exemption. Or the ledger says you will cross the sales cap by October. A cottage food law lets you cook at home because what you make is low-risk and you hand it to the person who eats it. Step past either condition and the state wants an inspected kitchen behind you.

The five kitchens, in order of oversight

Your home kitchen under a cottage food law

Typically the exemption means no license and no routine inspection. In Ohio's words, a cottage food production operation "is exempt from inspection and licensing." Minnesota requires an annual registration whose card now reads "This is not a license." The trade is a short list of allowed foods (our guide to what counts as cottage food has the pattern), direct sales, in-state sales, and in many states a sales cap. The cornerstone guide to starting a cottage food business covers the setup.

Cottage food does not have to be made at home, either. Minnesota's guidance says it "can be produced in a home kitchen or in a commercial kitchen." Renting hours in a licensed kitchen does not change your status; your license does.

A licensed home kitchen, where your state offers one

Some states will inspect and license the kitchen in your house. Ohio licenses a "home bakery," defined in Chapter 911 of the Ohio Revised Code as a home with "only one oven, in a stove of ordinary home kitchen design." It may make what a cottage food operation cannot: "potentially hazardous bakery products (such as cheese cakes, cream pies, custard pies, pumpkin pies, etc.) which require refrigeration." The license is $10 a year, and home bakeries "may distribute their products outside of the state of Ohio," which cottage food, sold "only in Ohio," cannot.

In California, a Microenterprise Home Kitchen Operation, or MEHKO, is a permitted, inspected home kitchen that cooks and serves meals. Alameda County's FAQ lists the terms: one routine inspection a year, an accredited food safety manager course, no more than 30 meals a day or 90 a week, gross sales under $100,000, and food "prepared and served the same day." A MEHKO cannot sell to wholesalers, retailers, or mobile vendors, or at farmers markets.

Not every state has a path like this. Minnesota does not: "A food license requires that food is made and stored in approved facilities; not a home kitchen."

A shared-use or commissary kitchen

A shared kitchen is a licensed commercial kitchen that rents time to other food businesses. The Illinois Department of Public Health's December 2024 guidance calls it "an intermediate option" for a business scaling up from cottage food to a food establishment, or testing a recipe for a Time/Temperature Control for Safety (TCS) product. University of Florida extension describes rentals "by the hour, day, or month."

Illinois sorts shared kitchens into two kinds. Some are built to host multiple users; depending on the agreement, each user holds a separate license or operates under the owner's. Others are working food businesses renting their off-hours, and those "will likely require a separate food establishment license" for each user. Minnesota's directory is blunter: "you need your own license at the kitchen from the appropriate food regulatory agency." The facility's license covers the building. Yours covers what you make in it.

A kitchen incubator

An incubator is a shared kitchen with a program attached: classes, coaching, help with licensing, sometimes distribution. Cook County, Minnesota, built a community commercial kitchen in 1993 and rents it to incubator businesses at $10 an hour. In the 2021 survey of shared kitchen users (Colorado State University and The Food Corridor, with USDA funding), almost 80 percent said the kitchen helped them through their regulatory requirements.

A space of your own

At some volume it makes sense to lease and build out a kitchen you control. University of Florida extension, citing the 2018 Shared Kitchen Toolkit, says the build-out "can run up to $100–$300 per square foot." You take on plan review, your own license, and routine inspection. The Florida Farmers' Market Association gives the counterweight: "commissary rental costs can become more expensive than operating a permitted facility if the business grows and increases production." Our guide to when demand outgrows your home kitchen weighs this step.

Cost, permissions, and oversight side by side

Why wholesale is the line that matters most

Cottage food laws draw the line at resale because of what the kitchen is, and Michigan explains it best. Asked why a producer cannot sell to a favorite restaurant or grocery store, MDARD answers: "Because your home kitchen is unlicensed and not inspected, the safe food handling practices are not evaluated by any food safety official," so the food "is not considered an approved source." Minnesota states the consequence: "Manufacturing food to sell to other businesses for resale (wholesaling) requires a food license."

Ohio is the exception that proves the point. It lets cottage food operations sell through grocery stores and restaurants, but "only in Ohio," and it still bars every refrigerated product. Once a buyer needs an approved-source kitchen behind the label, or the product needs a refrigerator, most states put you outside the exemption (Texas and the few food freedom states are the exceptions). Our piece on selling to cafés and shops has the state-by-state detail.

Shipping follows the same logic. Minnesota bars cottage food for people from the mail and commercial delivery; pet treats are the one exception. Michigan allows internet and mail order, but a product "may only be sold or delivered within Michigan." Ohio's cottage food stays in Ohio; its licensed home bakeries may ship out of state.

Five signals it is time

1. The cap is in sight. If your running total passes three-quarters of your state's limit with a season still to go, start kitchen shopping now.
2. Your best idea needs a refrigerator. Cheesecake, cream pie, garlic in oil, anything Ohio's list calls potentially hazardous. Most cottage food laws exclude these outright.
3. A buyer asked. A café, or a corporate order with an invoice. In most states that is wholesale, and wholesale means a license and a licensed kitchen.
4. You want to ship. Out of state means an inspected kitchen in every state cited here; in Minnesota, even in-state mail is off the table.
5. The hours no longer fit the house. In the survey, 35 percent of users rented 20 hours or less a month and 15 percent rented more than 80. If your home oven already runs a commercial schedule, you are paying for a kitchen in family time.

What a shared kitchen will ask of you

Surveyed users needed an average of five requirements before their first production day: 93 percent had to complete food handler training, 89 percent carry liability insurance, 85 percent show a tax ID or business license, and 62 percent satisfy county health rules. Cook County's list is concrete: a Minnesota Department of Agriculture retail or wholesale license, liability insurance, a Food Protection Manager certification, and a cleaning charge of $30 an hour or more if you leave the kitchen dirty.

Illinois's checklist for renters asks what an inspector would: a current food establishment license and a pest control program, designated secure storage, who monitors the cold-holding units when nobody is scheduled, and whether the schedule is shared with the local health department. Call that health department before you rent; the kitchen's license does not tell you what yours will require.

Run the numbers before you rent

Use the Florida association's example. Three hours at $30 an hour is $90; add $100 of ingredients for 30 jars of salsa and each jar costs $6.33 before labor and packaging. Run that on your own product at the kitchen's actual rate, then check it against your pricing worksheet.

The survey gives a sobering benchmark. Among the 100 businesses that shared financials, average annual sales were $19,500 and 32 percent sold under $10,000; across the sample, rent averaged 36 percent of sales. Many were doing fine: 64 percent of those under $40,000 sold at farmers markets, and half of those over $80,000 had reached grocery or retail shelves. Still, a third of revenue is a real number. The most common path in the survey, home kitchen to shared kitchen, works best when the products you move there are ones a home kitchen cannot legally make or sell.

The first phone call is not to a kitchen. It is to the health or agriculture department that would license you there, with two questions: what license will I hold at a shared facility, and what does my product require? Then ask the kitchen for its license number and rate sheet. If the answers line up with the signals above, you are not leaving cottage food behind so much as adding the kitchen your next product needs.
