Landlord brought a cat into residence. I am severely allergic and advised him of same. He continued to allow the girlfriends pet into home. I even went to hospital unable to breathe. The girlfriend & cat have moved in and now I have to find a new place to live. Should he reimburse me for the 6 months that he continued this practice after I told him about the problem.

He may be liable for medical expenses if you notified him that it was a problem. As far as rent goes your continued residence has a price to pay for it. Was any other arangements made for adding residents or was the gf living there when you moved in ?

Wasn't even dating when I moved in. My granddaughter also had a reaction to the cat & then I specifically asked a second time about the cat. Was told it was only a one time thing. I asked to be notified if it was coming back so I would make sure I didn't have a grandchild here & I would make other arrangements for myself. We share a house, he is downstairs & I'm upstairs. A door was installed when I moved in to separate us. I am unable to find another place, but am looking. Disabled and on a fixed income.

I will say no, unless you have a signed lease that states there are no pets.
Or if he knew of this prior to renting to you.

If he was aware of this, only after he moved a cat in, he was under no obligation to move the cat.

He does have to give you proper notice to move out, before you move.

He could be expected to keep the cat out of your room.

Did you continue to live in the house for those 6 months? Or did you pre-pay 6-months rent but then moved out and did not live in the residence for the 6 months you had pre-paid? If the former, then no - you used the residence. If the latter, then I think it really depends on what your contract says about early termination of the lease.

What is the lease agreement? What do you have on paper? If It is just a "Gentlemen's" agreement then I think you're out of luck.
