whats the laws on running a tattoo business out of your home?

[Rof]

I am apprenticing, and was weighing out my options on what I could do when I am able to provide perfect tattoos with no supervision/guidance.. and as a starter wanted to know what the laws are or if even allowed to run a tattoo business out of your house. This of course would be in a section constructed to provide such service.. but what would be the regulations on a location to qualify as appropriate for running a business of this type?
