Deli Below My Apartment Burned Down In Nyc

Hello,

Last week the deli below my apartment in Brooklyn, NY caught on fire and the damage was extensive. While I don't believe the fire actually spread to my apartment, it was hot enough that the roof collapsed and my building's management has ended my tenancy. I have a few questions:

1) I did not have renter's insurance, does this mean that I have no recourse to be compensated for my damaged furniture (couch/loveseat/bed) plus some computer monitors and other various items that were damaged? The fire originated in the deli downstairs, so is there any chance their insurance/the building insurance could help reimburse me for these items?

2) I understand not being able to live there while the building is being repaired, but are they allowed to just terminate my lease like that? I was told I would need to find new housing and that they could not offer any assistance in that regard.

Thanks in advance for any information you can provide.
