Can my landlord force me to put him as additional insured?

[Cassie Kessie]

So I signed a lease with my landlord and it states I have to get insurance through a specific insurance agency and to list him as additional insured. Is this legal? Shouldn't he have home owner insurance for this? I am worried due to the fact he has already caused damage to my property. He destroyed my sons comforter. Never replaced it. I have come home and he has left spray paint all over my floor. He has also on my security camera allowed the other tenants of my building into my apartment and TOOK MY DOG OUT OF MY APARTMENT. He is threatening to either make him additional insured or I have to leave. I reside in the state of NEW Hampshire

Cassie, I'm a NH landlord.  I believe he can require that you list him as additional insured.  It is normally no downside to you other than some insurance companies charge a normal fee to add him.  
I think the bigger issue is his behavior, but that's up to you to decide whether to deal with it.  I know there is such a housing shortage in NH that finding a new place is difficult.
Good luck.
