Each state has their own laws. I have a cousin who has an add on to her house and she operates "Rose's Bakery". Similar to the photos posted. She is health dept inspected each year for food safety. Dairy is highly regulated. Another cousin of mine is a dairy farmer, every other day the milk truck comes. He has a gas powered setup that keeps the big milk tank up to temp. He is inspected by the milk safety board or whatever twice a year. (he was just complaining to me how many multifold paper towels the inspector uses when he washes). I get my raw milk from him, but it's gifted or bartered. Eggs are not a problem to sell, farmer's mkt home canned, veg, baked goods are not a problem but I've never seen home canned meats sold. Home dairies that sell to the public can sell raw milk advertised for animal feed. Not advertised for human consumption. I just helped out with food sales at the last big fowl sale in Yoder. We sold burgers, chips, candy, soda, ice cream. We were not inspected, and didn't see an inspector there, but I did see a child services officer walking around, which was weird. Had his badge on. We probably served 250 people. Everything looked pretty clean and on the up and up, although I did give a few suggestions...I ran a commercial kitchen at our preschool for 16 yrs. Other people running home businesses, like a harness shop do need to follow local laws concerning home businesses. The Amish are not obligated to pay into social security, unless they want to claim it as seniors. It's not mandatory. Selling cream pies in a building that does not have refrigeration is not allowed. Although, I buy butter at the farmer's mkt. Comes in a 2 lb roll and the lady sells it out of a cooler. I have a relative who is going certified organic on his grains, and that's been a long process with lots of inspectors. He also does his own honey and they sell it without problems. Another money maker is using your dining room to host Amish dinners. My favorite cousin and her daughter do this about 4 x a year. People RSVP in advance, the group can request certain food items (like types of pies), and usually about 30 are served at a time. The last one she did, the people paid double, so they could eat a dinner, and also take a complete dinner home. She served meatloaf, potatoes and gravy, a vegetable, bread rolls, relish items, and pie. She had a small table nearby where she sold home canned items and honey. Home dinners aren't regulated. I think things are ok as long as no one complains to the powers that be.
