Where did you get that from?
It sounds like to me you got an inexperienced landlord. Did you guys sign a lease? If so, what duties are designated to each of the tenants?
I know when I signed the lease for this place, I am responsible for the repair and maintainance for everything in the kitchen. The only thing the landlord has to do is maintain the lawn and the hallways and the lobby. My last place required me to inform the landlord of anything in disrepair, fix them, then give him the bills to be compensated for them; he also required me to mow the lawn. Only thing he had to do was pay the utility bills.
Did you guys sign a lease? If not, the only legal thing that bond you guys is that in exchange for rent money, you have been given the privilege to stay there. Without a lease, she is not required to fix anything or replace anything. If you guys did sign a lease, then there would be a list of duties assigned to the landlord and the individual tenants.
