We have an insured written on a HO4 Renters policy. The landlord and the property management company want to be listed as additional insureds. It is not acceptable to them to be listed as additional interests.

Can you provide some insight as to whether it's common for both of these parties in this situation to be listed as additional insureds, whether there are ISO forms that accomplish this, etc?

An additional interest is for another party similar to a mortgagee who has a financial interest in the property. With a tenants policy, additional interest isn't applicable. Additional insured is, and ISO Form HO 07 50 05 11 Additional Insured – Managers or Lessors of Premises Leased to an Insured is designed for just such a situation. It provides coverage for liability to the party listed in the schedule arising out of the ownership, maintenance or use of that part of the premises leased to the insured. I'm not sure how common it is, but it's certainly doable and ISO has had a form for it since 2000, and other additional insured endorsements since at least 1984.

Editor's note: 

An astute subscriber pointed out that per the ISO manual, the HOo 07 50 is for use when the HO 07 01, Home Business Insurance Coverage Endorsement is on the policy. We stand corrected.
