TCS foods — those requiring refrigeration for safety — are not permitted under DC's cottage food framework. Here's what that means, why it's the rule, and what your options are if prepared meals are your goal.
Washington, D.C.'s cottage food law (D.C. Official Code § 7-742.01 et seq.; DCMR Title 25-K) only permits the sale of non-potentially hazardous foods — products that do not require time or temperature control for safety. Prepared meals, soups, stews, casseroles, fresh pasta dishes, egg dishes, and any food that must be kept refrigerated to remain safe are TCS foods and are not allowed under the cottage food program.
This is not a loophole or a gray area. DC Health is explicit: "A cottage food business is not allowed to sell foods which require temperature control for safety (foods that require refrigeration in their finished state)." If your product needs to be kept cold after it's made, it cannot be sold under a cottage food registration.
If prepared meals are your goal, there is a path — but it involves a separate licensing framework through DC Health's food establishment program, not the cottage food registry. This page explains both the prohibition and the alternative routes.
TCS stands for Temperature Control for Safety. It's the FDA's current term for what was previously called "potentially hazardous food" (PHF). A TCS food is any food that requires time or temperature control during storage, preparation, or display to limit pathogenic microorganism growth and toxin formation.
The science behind it: certain foods contain the moisture, nutrients, and pH conditions that bacteria like Salmonella, Listeria monocytogenes, Staphylococcus aureus, and Clostridium botulinum need to multiply rapidly. When these foods are held in the "danger zone" — between 41°F and 135°F — for more than two hours, bacterial counts can reach unsafe levels.
In a licensed restaurant or commercial kitchen, these risks are managed through refrigeration equipment, temperature monitoring, HACCP plans, and regular health inspections. A home kitchen operating under cottage food law does not have the same controls, which is why DC's regulations exclude TCS foods from the cottage food program entirely.
The key question for any food is simple: Would it need to be kept refrigerated after you made it? If yes, it's a TCS food and is not permitted under DC's cottage food registration.
The following food categories are explicitly outside DC's cottage food framework. None of these products can be made and sold under a cottage food registration, regardless of how they are packaged or labeled.
| Food Category | Why It's Prohibited | Licensing Path Available? |
|---|---|---|
| Soups, Stews & Chilis | Cooked animal and plant foods require refrigeration; TCS foods under FDA definition | Yes — DC food establishment license |
| Cooked Meals & Entrees | All hot-held or refrigerated prepared meals are TCS foods | Yes — DC food establishment license |
| Fresh Pasta Dishes | Fresh pasta is TCS; cooked pasta with sauce is TCS | Yes — DC food establishment license |
| Rice & Grain Dishes (Cooked) | Cooked rice and grains are TCS foods — support rapid bacterial growth | Yes — DC food establishment license |
| Casseroles & Baked Entrees | Contain TCS ingredients (eggs, dairy, protein); must be refrigerated | Yes — DC food establishment license |
| Meal Kits with Fresh Ingredients | Raw proteins, fresh produce, dairy components are TCS | Yes — DC food establishment license |
| Egg Dishes (Quiche, Frittata) | Cooked eggs are TCS; require refrigeration within 2 hours of cooking | Yes — DC food establishment license |
| Breakfast Bowls | Combination of TCS ingredients (eggs, dairy, cooked grains) | Yes — DC food establishment license |
| Salads with Perishable Dressings | Mayonnaise-based and dairy dressings are TCS | Yes — DC food establishment license |
| Cream-Filled Pastries & Custards | Dairy cream, custard, cream cheese — TCS fillings and toppings | Yes — DC food establishment license |
| Cheesecakes | Dairy-based; requires refrigeration; TCS food | Yes — DC food establishment license |
Cottage food law is not the only way to sell home-made food in DC. If you want to sell prepared meals, soups, fresh pasta, or any TCS food, you can pursue a DC food establishment license — a more complex but viable route that unlocks a much broader product range.
You cannot legally produce TCS foods for sale from your home kitchen under any DC license. You'll need access to a DC Health-approved commercial kitchen. Options include renting time at a commercial kitchen incubator, sharing space in a licensed restaurant during off-hours (a "ghost kitchen" arrangement), or leasing a dedicated commercial kitchen space. DC has a growing number of incubator kitchens — including organizations like Mess Hall, which helped launch dozens of food businesses in the NoMa neighborhood.
DC Health regulates food establishments (restaurants, caterers, food manufacturers) separately from cottage food. You'll need to apply through DC Health's Environmental Health Administration for the appropriate license category — food manufacturing, catering, or retail food establishment. This process involves a plan review, facility inspection, and approval of your menu and production process. Contact DC Health for current requirements and fees: food.safety@dc.gov · (202) 535-2180.
For certain TCS food products, DC Health may require a Hazard Analysis and Critical Control Points (HACCP) plan documenting how you will control food safety hazards at every step of production. Your CFPM certification (already required for cottage food registration) is a strong foundation, but commercial TCS food production requires more detailed documentation of temperature controls, holding times, and corrective actions.
You'll still need a Home Occupation Permit is not applicable here — instead, you'll need a Basic Business License (BBL) from DLCP with the appropriate endorsement for your business type, a DC tax registration from OTR, and potentially a business entity registration if operating as an LLC. See the Start Your Business page for the full business formation overview.
With a food establishment license, your sales channels are broader than cottage food: farmers markets, delivery, online ordering, catering events, pop-ups, and potentially wholesale to restaurants and retailers. The trade-off is higher startup cost, kitchen rental fees, and more rigorous ongoing compliance requirements.
DC has several commercial kitchen incubators and shared kitchen facilities designed for food entrepreneurs. These spaces offer licensed, inspected kitchen time by the hour or month — exactly what you need to produce TCS foods legally. Search for "shared commercial kitchen DC" or "incubator kitchen Washington DC" to find current options. Prices typically range from $15–$30/hour for basic kitchen time.
For prepared meals and TCS foods, contact DC Health's Environmental Health Administration directly to understand the current licensing requirements for your specific product and business model. Requirements vary based on whether you're operating as a caterer, food manufacturer, or retail food establishment. Email: food.safety@dc.gov · Phone: (202) 535-2180.
Many successful DC food businesses started with cottage food registration — selling shelf-stable baked goods, jams, and packaged snacks — to build a customer base, test product-market fit, and generate revenue. Once the business has traction, they've moved to a licensed commercial kitchen to expand into prepared meals and TCS products. You don't have to solve everything on day one. A jar of jam sold legally today can fund the commercial kitchen rental you need tomorrow.
Even for home food sellers operating legally under cottage food rules, understanding TCS principles makes you a better, safer food maker. These are the fundamentals that your CFPM training covers — and that DC Health expects every registered cottage food business to know.
The temperature range in which TCS food bacteria multiply most rapidly. TCS foods should never be held in this range for more than 2 hours total (1 hour if ambient temperature is above 90°F).
TCS foods must be held at 41°F or below when refrigerated. This slows bacterial growth to safe rates. Standard home refrigerators should be set to 37–40°F to ensure consistent compliance.
Hot-held foods must be maintained at 135°F or above. This applies to foods served warm at events — soups, entrees, breakfast items. Applicable to licensed food establishment operations, not cottage food.
TCS food left in the danger zone for more than 2 hours must be discarded. This rule applies in commercial operations. For cottage food sellers, it's a reminder of why TCS products are excluded — the risk window is too narrow for home-based commerce.
