but a landlord can always not renew a lease for any reason when the current one is up
A friend of mine who runs a business sued his landlord and "won" Well, his lease is up for renewal and he's unable to renew it. They put too many conditions on it. He complained to the court, the court said "We told him he has to renew your lease, and he is offering you one to sign"
If you ever start a fight with your landlord, you need to be ready to move.
