Can you sell homemade jam in Massachusetts?
Updated

Yes, but only from a permitted home kitchen. Massachusetts has no unlicensed cottage food exemption: a home kitchen that sells food is a "residential kitchen," and if you sell directly to the people who eat the jam, your city or town board of health must inspect and permit it first [1]. Jams and jellies get special treatment. The state bans thermal processing in sealed containers in every residential kitchen, and jams and jellies processed that way are the one stated exception [1] [2].
The thermal processing exception, and what it leaves out
The Department of Public Health (DPH) lists five processes no residential kitchen may use: "acidification, hot fill, thermal processing in hermetically-sealed containers, vacuum packaging, and curing/smoking." Then it adds: "The only exception is jams and jellies that are thermal-processed in hermetically-sealed containers" [1]. In plain terms, a water bath canned jar of jam or jelly is allowed. DPH also names foods a residential kitchen may not make, including tomato and barbecue sauce, pickled products and relishes [1].
Read the list closely before you plan your products.
- Hot fill is on the banned list. The exception names thermal processing, so a jar that is filled hot, capped and inverted, with no water bath, does not appear to fit it. Process in a boiling water bath (how water bath canning works) and confirm the method with your board of health.
- Acidification is on the banned list. Pepper jelly and jams with added vegetables usually depend on vinegar or lemon juice to bring a low-acid ingredient into a safe range. DPH does not name pepper jelly either way, but because it relies on that banned step, expect the answer to be no and ask before you make any for sale. See pepper jelly.
- Low-sugar jam, freezer jam and fruit butters are not mentioned in the DPH questions and answers [1]. A frozen or refrigerated jam would fall under the rule that residential kitchens "may not prepare finished products that require hot or cold holding for safety" [2]. Do not sell canned pumpkin butter under any permit; see pumpkin butter.
Your regulator may ask for proof. DPH says operators "may be required to provide laboratory evidence" such as pH or water activity results from a private food laboratory, and that using one standardized recipe the lab has evaluated helps keep a product safe and consistent [1].
Retail or wholesale residential kitchen
| Retail residential kitchen | Wholesale residential kitchen | |
|---|---|---|
| You sell to | Consumers directly, including at farmers markets and craft fairs and by internet or mail [1] | Retail stores, grocery stores and restaurants that resell [2] |
| Who inspects and approves | Your local board of health, which permits you as a cottage food operation under 105 CMR 590 [1] | DPH Food Protection Program, which licenses you under 105 CMR 500 [1] |
| What you may make | Cottage food products that keep at room temperature, including jams and jellies [1] | Foods that keep at room temperature and need no refrigeration [2] |
The wholesale license is what lets your jam onto a shop shelf. The same banned processes apply to both [1]. If your plans include shops, the patterns other states use are compared on selling jam to shops and cafes.
What the state sources do not settle
The DPH questions and answers give no permit fee, no inspection schedule, no sales cap and no required label statement for residential kitchens [1] [2]. Fees and inspection practice are set locally, so they can differ from one town to the next. Before you apply, ask your board of health:
- What the retail residential kitchen permit costs and how often it renews.
- Whether it will inspect before the first sale, and what it checks (water supply, storage, pets, handwashing).
- Whether it wants lab results for each jam or accepts a tested recipe.
- What it expects on the label beyond the federal elements.
Every jar still needs the federal basics: the name of the food, net weight, ingredients, allergens and your name and address. See what a jam label must say.
Online orders and buyers outside Massachusetts
A retail permit covers internet and mail sales to consumers [1]. For buyers in another state, DPH says operators "should confirm that they are in compliance with both Federal law and the state laws where they are doing business" [1]. Many states do not accept home-made food from outside their borders, so check the buyer's state before you ship.
Local board for retail, DPH for wholesale
For a retail permit, start with the board of health in the city or town where your kitchen is. For wholesale, contact the DPH Food Protection Program at 617-983-6712 or fpp.dph@mass.gov [1]. The official page is DPH's Residential Kitchen Questions and Answers [1]. Verified in October 2026.
Processing jars the way the permit expects
With hot fill on the banned list, plan on a boiling water bath for every batch and confirm that reading with your board. The method is on water bath canning, and the times by elevation are on processing times for jam.
