Maryland's cottage food rules are built around a simple test: is your product shelf-stable? Understanding what that means — and what the $50,000 annual cap covers — is the foundation of running a legal home food business in the state.
Every cottage food rule in Maryland flows from one fundamental question: does your product need refrigeration to stay safe? If the answer is yes, it's off-limits under the cottage food exemption. If the answer is no — if your product can sit on a shelf at room temperature without becoming dangerous — you're in the right zone.
Maryland's regulations use the scientific term "non-potentially hazardous food" (also called non-TCS, for Temperature Control for Safety). These are foods that don't support the growth of pathogens — disease-causing bacteria like Salmonella, E. coli, or Listeria — at room temperature. The science behind this comes down to two measurable properties: pH and water activity.
Both properties work together. A food that's very acidic (low pH) or very dry (low water activity) doesn't give bacteria the conditions they need to multiply. Hard candy, for example, is safe because it has almost no water available. Strawberry jam is safe because the natural acidity of the fruit, combined with proper hot-fill canning technique, keeps it at a pH of 4.6 or below. Cookies and crackers are safe because they're baked dry. Understanding these two variables helps you assess any product — even ones not explicitly named in the rules.
Quick Rule of Thumb: If your product needs to go in the fridge after opening — or if you'd be uncomfortable leaving it on a counter for two weeks — it's probably a TCS food and not eligible under Maryland's cottage food rules. When in doubt, contact MDH at (410) 767-8444 or [email protected] before investing in production.
The cap applies to gross revenue — the total amount customers pay you, before any deductions for ingredients, packaging, farmers market fees, or other business expenses. If you sell $30,000 at farmers markets and $20,000 through your website, you've reached the cap at exactly $50,000. Farmers market booth fees you paid are not deducted from your total.
You have two options: stop selling cottage food products until January 1, or transition your operation to a fully licensed food establishment. The licensed path requires a commercial kitchen (you cannot use your home kitchen), a food establishment license from MDH, plan review and approval, and a pre-opening inspection. Many sellers use the cottage food period as a proving ground — building their customer base and product line — before making the leap to commercial scale.
Planning Tip: Start tracking your sales from day one. The SellFood Sales Limit Tracker (available free with your seller account) lets you log every sale and see your running total against the $50,000 cap in real time — so you're never caught off guard mid-season.
Track your cumulative annual sales against Maryland's $50,000 cap. Get alerts when you're approaching the threshold with time to plan your next step.

Maryland's cottage food rules don't prescribe detailed storage protocols the way a licensed food facility would — but the law does establish that products must be stored at your home kitchen, and that the food must be non-potentially hazardous. Common-sense good food manufacturing practices apply.
Sampling at Events: You are permitted to offer samples of your cottage food products at farmers markets and public events — as long as the samples are non-potentially hazardous and pre-packaged in your home kitchen before the event. You cannot cut, portion, or package food on-site at a market table.
