hmm and I thought my former landlord was bad. Roof leaked, 2" of water in the hallways upstairs where he had 6 apartments. Got his insurance settlement, never replaced the rugs - they are so moldy and musty I don't know how anyone could live up there. He refused to claim my damage on his insurance at that same time, we lost a Teleflora Guide ($399 +) and the Teleflora Wedding Book ($349 +) and a sympathy guide ($149 + ) and a bunch of designed permanents.
I had to call my insurance, make a claim, then they went after his insurance who even reimbursed me my deductable.
Two years later a toilet broke, more water in my shop, ruined some more merchandise (I had moved the books to a different counter). Again, he would not claim. My insurance sued his, I got my money & deductable back. Third time, bathtub leaks....same thing. Finally he sold after collecting all monies and not fixing much of anything with the settlements. In comes current landlord who BTW lives in Connecticut.
Last week I come in to a tile hanging down dripping brown water. Rug is soaked out to middle of the room. A glass container holding a candle is 1/2 full with brown water. Call building manager...she paces, hems and haws and finally calls a plumber....
Luckily this time, no merchandise that can't take water ....all washed up. Leak was behind toilet (incoming water not outgoing) and the brown was from the beams it traveled through to get to my area. The new landlord had the pipes properly taken care of this time.
In your case, that's a "slum lord" property looks to me. If he can't afford to lose you (as my former landlord couldn't)..I'd call someone to notify him of his duties....
I don't have a lease, never have, and have outlasted 5 landlords...
