All food prepared for the public must be prepared in an inspected, approved, and licensed facility. Seldom does any municipality allow it to be in a private home. If allowed, it cannot be in any part of your living quarters.
A recommended place to start to get information on food manufacturing is the Basic Training class at OSU Food and Ag Center in Stillwater (405-744 6762). This is an all day class on the third Thursday of even numbered months, but you are required to call and enroll. There is more information on their website.
Food manufacturers must follow the "Good Manufacturing Practices" - Chapter 260 of the Oklahoma State food code. A copy can be found on the Oklahoma State Health Department's web site.
When looking for a location to produce your product, check with the local municipality's zoning department to see if the address is zoned for "Food Manufacturing".
There are a lot of things that will need to be done at a location before it could be approved, possibly more that you or the owner would want to do.
Plans (floor and equipment plans/blueprints) will be required and there is a fee for checking and approving these. Many times the city will require a building permit even if the building is already there.
A final inspection, approval, and issuance of license application(s) is required before starting any production.
You might consider a coprocessor- someone already in the business and has the equipment to make your product.
