Ask a landlord-tenant lawyer and get answers ASAP
Hello and welcome. I am working on your answer and will be right back!
technically, they are free to change their terms and requirements.
That said, they cannot discriminate on basis of race, gender, age or nationality in doing so.
Often they will waive this if someone else signs or there is additional security given. sometimes if pushed on it, they will waive it without anything more, unless they want a new tenant.
It sounds like they may be discriminating on basis of disability. You can raise that and they should back off.
Their lawyer will likely tell them if they ask they are risking a lawsuit.
Kindly rate me 5 stars.
