Insurance questions regarding a shop

[Jason Davis]

Hi,

I have a shop on the same property as my house located in town in a residential area. The shop has three units, all under one utility bill. No water, no sewer. Just heat and electricity that I pay. 

I want to rent out two shop units to people who might want a small work space for a car or a project and I keep the third one for my personal use.  The entire property is listed as a single family home. 

I spoke with my home owners insurance and it doesn't seem like that's an option. So I started looking into a commercial policy for the shop. Does anyone have a similar property and if so what did you do to get proper insurance. And maybe a few insurance company recommendations. Any idea what a policy like this might cost?

Thanks
