Tenant Still in Possession After Lease Expires Must Obey Terms of Original Lease

What Happened: A medical tenant decided to remain in possession and continue paying rent after its lease expired. A few months later, Hurricane Irene blew through town and inflicted major damage, forcing the tenant to move out. The tenant sued to recover its security deposit; the landlord countersued to recover the costs of rebuilding, noting that the tenant had parked its car inside the building before the storm, in violation of the lease, and that the car was forced through the wall by the rush of floodwater in the building.
