Of the many types of eviction notices, each notice bears its own specific purpose that must be used properly during the eviction process. Unlike other forms of eviction notices, where the justification for eviction is a violation of the lease, 30 day notices are simply associated with the end of the lease, or lease expiry. Similar to other notices is the fact that terminating an ended lease require notices, a 30 day notice, to be issued to the tenant in order to evict. Issuing a 30 day notice also has special rules that may apply. In some cities, the landlord can terminate a lease without cause, whereas other will require some sort of reason. Tenants rights also dictate that the eviction is unlawful if the result of discrimination. After a period of a 30 day eviction notice has elapsed, landlords can advance the case by filing for an eviction in court.
