OK. Thanks for the information.
IF your lease term is up, then there's no right to force the landlord to allow you to remain or to re-rent the property past that term. This is so even in a situation where an occupant/tenant is disabled. You would have a right to claim housing discrimination
IF the landlord was not renting to you based on the fact that your child is disabled. If that were the case, you could sue under the Federal Housing
Act and the ADA for discrimination.
However, if the landlord is telling you that he's going to allow his daughter to move in, and he's not renting the property any longer, then it isn't likely that he's doing this because your child is disabled. Thus, there'd be no right to sue or legal cause of action to require him to rent to you.
Instead, you would have to either convince the landlord to give you a new lease or you'll have to find alternate housing. Maybe you can work something out with the landlord that will allow you to stay until you find a new place. Hopefully, the landlord will agree to that and let you rent month-to-month.
But, unfortunately, if there's no discrimination present, then the landlord can choose not to renew the lease once it expires, and if that is done, you'll have to vacate.
Thanks for your question, and if you have any additional questions, please do not hesitate to ask.
