I am caring for 2 ladies and getting another. I am a CCG; does my home need to be licensed?

You will need to check with AZ state laws. Everyone on this forum are from different states and countries, so you must check it yourself. Start at the Dept of Health and Human Services for your county. You are talking about a business, so you will be regulated, need a business structure (like LLC), insurances, meet inspection standards for cleanliness and safety, compliance, etc. Must not be cash-based or you will run afoul of the law. Good luck!
