I just started my business. I have not even received my equiptment yet. I plan to be just mobile, but may do sprays out of my house. Use you home address. You have to put down a physical address to get the license. Guys it is no big deal.
Mobile
spray tanning is a home based business whether you decide to rent out some salon space in the future or not. Now if you actually own a salon, then that is different.
I hope this info helps.
