Once they occupy an apartment, tenants have a "right" to have that lease renewed. I don't think landlords can refuse to renew a lease without cause. Which means that, in practice, the first lease is for as long as the tenant wishes to stay.
Of course. That comes as no surprise.
Legally, I feel the lease contract should be voided after the government steps in and forces a change to the terms of that contract. That would happen in not-Bizzarro-World. And my personal feelings on the matter obviously don’t matter.
