Type of Insurance I should ask my garage renter

[Nicole He]

Hi guys!

I have a commercial property ( 19 unit apartments with 4 garages), I want my garage renters to get an insurance policy like a renter's insurance where I can be added as additional interest, however, I was told that renter's insurance does not fit because he is not living in the garage. My garage has an office and a powder room, however, it is in the residential area and would not pass as a commercial lease. Any recommendation what type of insurance best fit this type of rental? Thanks in advance!
