@Michael Pursell @Jonathan R McLaughlin is right about the liability, which made me think about homeowner's insurance.Be sure you talk to your insurance agent about whether an "unofficial rental unit" is covered or needs a different kind of policy.If there was some sort of claim, it wouldn't surprise me at all to see an insurance company deny the claim if it wasn't a legal, permitted ADU.

My question is, should I find the title insurance company or is that the buyers responsibility?
