I am a new host. I have a two unit flat. I reside in the one unit I have listed and family lives in the other unit. I have Allstate as my homeowners insurance and I was told that they will not insure both of my units due to my new business, even though I only list one unit. I am now in the market for a business insurance policy. Can anyone recommend a reputable insurance company in San Francisco that provides a business insurance policy for my units?
