The first thing you need to do is check the local statutes and any homeowners association to which you belong. Many HOA's and community rules prohibit the occupancy of the property by unrelated adults. Since you are operating a for-profit business you need to have an occupational license from the municipality where you live. Remember under CA law the house may not provide treatment or recovery services or it will need to have special icenses. Check out www.soberhousing.net
You must advise your insurance company ahead of time that you are running such a house or you will not be covered for liability claims. Your agreement should state that the guests are not tenants, and do not get any notice that they are being evicted. Otherwise you are going to have to evict them as if they were tenants. Take money in the shortest periods possible -weekly rather than monthly.
