Curious as to what to do as a landlord

[Margaret Dreesen]

I am a newbie at being a landlord.  My late husband and I had a small studio on the Chicago Gold Coast.  My tenant fell over his own cane and then called 911 in the middle of the night.  The fire dept used crowbars to break into the condo to take the tenant to the hospital.   They deemed it a life threatening situation. My tenant has been living in the condo for over a year and is out of the hospital and back at the condo.

The new outside fire door costs over 3000 USD.  Can I use some of the tenant's damage deposit to pay what my insurance does not pay? 

Any suggestions from you experts out there?
