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
