Renters Insurance by Landlord

[Michael D.]

I recall renting an apartment where the landlord required that I get renter's insurance through a specific company that they had an arrangement with. It was my policy, but they were specifically named as additional insured. In case of excessive damage they could make a claim against it, and they would be notified of a lapse in coverage.

Now, as a landlord myself, *I* want that for my tenants.

What is it called? How can I find out more about it? Have any of you done something like this?
