Have you tried? I haven’t tried it with the IRS, but I have tried asking my states permitting and planning department about the legality of various rental schemes for a property (that I didn’t own) and they were happy to look up the permits and tell me that indeed what I was asking about was not legal for that property. And further they let me know that tons of people do it anyway and that they don’t really check, but it’s a risk.
