A lot depends on the state you'll be living in and what kinds of services you'll be offering. Recovery homes don't usually have to be licensed, but if you're planning to offer treatment services, you'll probably be required to have paid staff who are licensed. Check the zoning laws for the area where you want to set up the house to find out whether you are allowed to put your home there. There is usually information pertaining to a state's policies for recovery homes on its government website.
