Massachusetts Cottage Food Law

Every Massachusetts city and town operates a local board of health under M.G.L. c. 111 with statutory authority to inspect, permit, and regulate food establishments within the municipality. A Residential Kitchen permit is obtained from the board in the city or town where the kitchen is located — there are 351 boards across the state and each one sets its own application form, fee schedule, training requirements, plan-review depth, and inspection cadence within the floor set by 105 CMR 590. There is no statewide application form, no statewide registry, and no statewide fee. Permit fees range from $0 (a small number of rural towns) to $200+ (Boston and a few larger cities), with most falling in the $35–$100 band. Permits are typically renewed annually with a re-inspection.

Boston operates the most structured residential kitchen program in the state. Application requirements include a property owner authorization letter (Boston is heavily renter-occupied), two sets of plans at minimum 11-inch by 17-inch showing the kitchen layout, a completed Plan Review application worksheet covering menu and production schedule, a Certified Food Protection Manager certificate (ServSafe Food Protection Manager, $125, valid five years), an ANAB-accredited Allergen Awareness Training certificate (ServSafe Allergens, $25, valid five years), a Workers Compensation Affidavit (required even for sole proprietors), and the $100 Health Division fee. The inspector visits the apartment, walks through the kitchen, verifies dishwashing temperature, confirms pets can be confined to a separate room during preparation, and signs off. The permit issues about three weeks after the inspection and renews annually.

Many Massachusetts municipal boards of health (Boston, Cambridge, Lexington, Concord, Tewksbury, and most mid-size to large cities) require the residential kitchen permit applicant to hold a Certified Food Protection Manager credential before the permit is issued. The most common accepted credentials are ServSafe Food Protection Manager (offered by the National Restaurant Association, $125, valid five years), Always Food Safe (valid five years), StateFoodSafety (valid five years), and Learn2Serve. The state does not require this credential under 105 CMR 590 as a baseline — the requirement is municipal. Smaller and more rural towns may not require it. The single most important question to ask your local board of health is whether ServSafe is required and which courses they accept; the certificate must be obtained before submitting the permit application in towns that require it.

Massachusetts has moved from a state-approved list of allergen training providers to an accreditation-based standard. Boards of health that require allergen awareness (Boston, Cambridge, Lexington, Concord, Tewksbury, and most mid-size to large cities) accept any training program accredited by the ANSI National Accreditation Board (ANAB). Common accepted programs include ServSafe Allergens ($25, valid five years), Always Food Safe Allergen, StateFoodSafety Allergen Awareness, and Trust20. The state Food Protection Program publishes an [Allergen Awareness FAQs page](https://www.mass.gov/info-details/food-allergen-awareness-faqs) covering accreditation standards. Smaller and rural towns may not require the credential.

The residential kitchen permit under 105 CMR 590 is direct-to-consumer only and shelf-stable only. A producer who wants to sell wholesale to a grocery store or restaurant, or who wants to make acidified foods (hot sauce, salsa, pickled vegetables), fermented foods (kombucha, sauerkraut), low-acid canned foods, refrigerated baked goods, or any TCS items must move to a state food processor license under M.G.L. c. 94, § 305A and 105 CMR 500. The food processor license requires a commercial-kitchen-grade facility (which may be a commissary kitchen rental at $20–$35/hour in most Massachusetts metros), state-level application and inspection, and ongoing compliance with the full 105 CMR 590 standards rather than the residential subset. The cottage food framework is intentionally designed as a low-friction entry point; the food processor license is the next legal step.

Does Massachusetts have a cottage food law?

Not as a standalone statute. The cottage food framework lives inside the state Retail Food Code at 105 CMR 590, specifically the Cottage Food Operation and Residential Kitchen definitions at 105 CMR 590.001(C)(2) and the operating guidance at 105 CMR 590.010. The Massachusetts Department of Public Health Food Protection Program sets the statewide minimum standards, but permitting authority is delegated to the local board of health in each of the 351 cities and towns under M.G.L. c. 111. The practical effect is that the rule you have to comply with is the combined product of the state code floor and your local board's specific requirements (fee schedule, training certificates, plan-review depth, inspection cadence, label wording). Massachusetts is one of the few states without a statewide cottage food statute distinct from the broader retail food code.

Is there a revenue cap on Massachusetts cottage food sales?

No statewide cap. 105 CMR 590 does not impose any annual gross-revenue ceiling on residential kitchen sales. Individual local boards of health may impose conditions when issuing or renewing the residential kitchen permit, but the Department of Public Health does not set a statewide number. In practice, most Massachusetts cottage food producers operate without a cap concern; the binding constraints are the allowed food list and the direct-to-consumer-only sales channel restriction.

Do I need a permit to sell cottage food in Massachusetts?

Yes — from your local board of health, not from the state. Under 105 CMR 590, a Residential Kitchen producing food for direct sale to consumers is treated as a permitted retail food establishment and must obtain a permit from the board of health in the city or town where the kitchen is located. The board reviews a plan, inspects the kitchen before issuing the permit, and renews the permit annually. Fees vary widely — Boston charges $100, smaller towns typically run $25 to $75, a few towns are free, and a few charge over $150. There is no statewide application form; each board uses its own. The five questions to ask your board before submitting are (1) what is the permit fee and renewal cycle, (2) do you require ServSafe Food Protection Manager certification, (3) do you require ANAB-accredited Allergen Awareness Training, (4) what does the kitchen inspection involve, and (5) what exact disclaimer wording do you require on the label.

Does my home kitchen need to be inspected?

Yes. Unlike many cottage food states that explicitly waive inspection in exchange for restricted food lists, Massachusetts requires the local board of health to inspect the residential kitchen before issuing the permit. The inspection typically covers the kitchen layout, the dry and cold storage areas, the dishwashing setup, the water source (private wells require coliform and E. coli testing under 310 CMR 22.04), the absence of pets during preparation, and the separation of business inventory from household food. Most boards re-inspect at least annually as part of permit renewal. The inspection depth varies — Boston runs a structured plan review process with engineered drawings, while smaller towns may do a single Tuesday afternoon visit.

What foods are allowed under Massachusetts cottage food law?

Non-time-and-temperature-control-for-safety (non-TCS) foods — items that are shelf-stable at room temperature and do not require refrigeration. The allowed list includes baked goods without cream or custard fillings (breads, rolls, biscuits, cookies, brownies, scones, fruit pies, unfilled donuts, frosted and unfrosted cakes with shelf-stable buttercream), jams, jellies, fruit butters, preserves, hard candies, fudge, brittle, dipped chocolates, dried herbs and spice blends, dry baking mixes, dry tea blends, roasted coffee beans, granola, trail mix, popcorn, vinegars, honey, and pure maple products. Cream-filled pastries, cheesecake, custard pies, custard-filled items, fresh dairy products, meat and poultry products, fish products, cut produce, garlic-in-oil, tomato sauce, BBQ sauce, pickled products, relishes, and salad dressings are excluded. Acidified foods (hot sauce, salsa, pickles) and fermented foods (kombucha, sauerkraut) are excluded — those products require a separate state food processor license under M.G.L. c. 94, § 305A.

Can I sell Massachusetts cottage food online or by mail?

Yes within Massachusetts; no across state lines. The Mass.gov Residential Kitchen guidance is explicit that direct-to-consumer sales include "events like farmers markets, craft fairs, and sales by internet or mail." A permitted residential kitchen may take online orders and ship by in-state mail or courier to Massachusetts addresses. Out-of-state shipping crosses into federal FDA jurisdiction, which does not recognize state cottage food exemptions and requires the producer to register as a food facility under 21 CFR Part 1, Subpart H and to comply with federal labeling and food-safety rules. The practical effect is that Massachusetts cottage food is an in-state-only market.

Can I sell wholesale to a grocery store or restaurant under the residential kitchen permit?

No. The residential kitchen permit under 105 CMR 590 is direct-to-consumer only. Wholesale to a grocery store, restaurant, café, or other retail food establishment requires a separate state food processor license under M.G.L. c. 94, § 305A and 105 CMR 500, with a commercial kitchen meeting the full 105 CMR 590 standards rather than the residential subset. A few towns will discuss farm stand wholesale exceptions for jams and honey produced by farms operating under M.G.L. c. 128, § 1A (the agricultural-use exemption), but the general residential-kitchen rule is direct sale only. The cleanest path for a producer who wants to wholesale is to start under the residential kitchen permit (to prove demand) and then transition to the commercial food processor license once the volume justifies the investment.

Do I need ServSafe or Allergen Awareness training to sell cottage food in Massachusetts?

It depends on your town. The state does not require either certification under 105 CMR 590 for cottage food operations as a baseline. Many municipal boards of health do — Boston, Cambridge, Lexington, Concord, Tewksbury, and most of the larger municipalities require both a Certified Food Protection Manager (CFPM) credential such as ServSafe Food Protection Manager and an ANAB-accredited Allergen Awareness Training certificate before issuing the residential kitchen permit. Smaller and more rural towns may not require either. The single most important question to ask your local board of health is which training certificates they require to issue the permit, because that controls roughly $150 to $200 in front-end cost and a few hours of training time before you can apply.

Who can work in the kitchen with me?

Only immediate family members residing in the household may prepare cottage food. Outside employees, contractors, friends, and family members who do not reside in the household may not participate in the food preparation steps — they may help with sales, packaging, marketing, and other non-preparation tasks. This is one of the rules that is reasonably uniform across Massachusetts towns; both 105 CMR 590 and the typical municipal board interpretation align on the family-only labor rule. The constraint is rooted in the inspection model: the inspector evaluates the kitchen and the residents who use it; expanding the labor pool would require a different inspection scope and a different permit category.

What about my pets — can my dog or cat be in the house during baking?

They can be in the house, but not in the kitchen during food preparation. The standard interpretation of 105 CMR 590 across most Massachusetts boards is that pets must be excluded from the kitchen during all food preparation steps. The inspector will typically ask how you plan to confine the pet during baking hours — a closed door to another room is sufficient in most jurisdictions. Boston is specific that "pets must be excluded during preparation" and that food preparation areas must not be co-mingled with pet feeding or litter areas. Multiple pets, free-roaming pets, and pet odors observable in the kitchen during inspection are common reasons for a permit application to require a follow-up visit.
