I live in Orleans County and went thru my local Department of Health to become certified. They have told me that if I decide to do wholesale or internet sales then I need to go thru the Dept. of Ag. I have emailed them with no response. So I will have to try calling which is always fun.
My process took about 6 months before everything was approved. I built a seperate bakery within my basement with all seperate appliances, everything. I then got my inspection through the local department of health and that happens once a year. I then have to go to my local town board and county board to get it voted on and approved. Because I ive in residential, my property needed to be converted to commercial, which it now is. So I was told that now I am save if I want to build a storefront right on my property, which my husband is planning on building a seperate building for me in the next few years. Once I am able to get ahold of the Dept. Of Ag, they will come to my house and do their own inspection.
When I first thought about doing the "bakery", the man that answered the phone at the Department of Health was trying to convince me that it is way too much work to even bother with it. But I went into the office and spoke with the female inspector, she was nothing but encouraging. Hopefully in your area you will have someone that is willing to help you and encourage you. They are there to help as well.
Good luck and let me know if you have any more questions. Hope this helped! It was a long process but I believe worth it. I am now able to quit my fulltime job to stay home with my kids and still bring in some extra income.
