The landlord installed faulty gas hookups (a washer was split, allowing a leak), said the fire marshall.
The landlord countered that no one could prove I did not "move and damage" the hookups, and claimed because I had signed a walk-through of the apartment (where we checked the burners did work at that time) I had signed away any responsibility from them. 2 lawyers agreed. We settled with letting me out of my lease shortly thereafter, heavily discounted rent on a new place for the remaining time, and a small sum of money to replace what I lost.
And You're still here! That's all the world needs.
