I am looking for any solid advice on how to set up a private tattoo studio in an apartment in San Francisco, with a focus on the permits, steps and any legal things I would need to do to make it legit and by the books. I'm gathering that there needs to be a business license and health inspection, zoning, etc. as well as a list of things like a sink in the room and sharps containers but, understandably, there isn't a lot of info on how to properly go about it.
Also, I am absolutely not a scratcher. I am a professional artist that has had a proper apprenticeship in a high profile shop in SF. I am blessed to be booked out way in advance and currently work in a great shop, but I am simply looking for a more intimate chill work environment and do not want to give a percentage to a shop anymore.
