How can a tenant obtain the insurance provider of their apartment

[Glenn R.]

My mother lives at an independent living apartment.  It's a nice place, but I have a couple of concerns that I would like them to address.  My main concern is there are a few dead trees around the perimeter of the parking lot that need to be removed.  Limbs have fallen on a couple of cars & caused damage, and could just as easily injure somebody.  I have approached the manager, but he just made excuses.

I would like to call their insurer to inform them of the obvious potential liability that is present.  How can I learn who their insurer is?  I'd think that information would be available to some kind of state agency.  Any tips on this?
