Pennsylvania does not specify how much notice must be given to a tenant when they are asked to move out without a cause. However, it is customary to give at least 30 days of notice under these circumstances. However, when a cause for eviction is provided, a Pennsylvania tenant may be given anywhere from 15 days (most lease term violations) to 0 days to move out (serious illegal activity).
