It depends. If you have a written lease, read through the terms to see whether it requires a specific kind of notice. If you plan to bring an eviction case because the tenant has broken any of the terms of the lease, you generally do not have to give notice before starting the case. However, if the tenant has not broken the terms of the lease, notice is usually required. If you give the tenant a proper written notice to vacate and they do not leave by the date in your notice, you may be able to bring an eviction case based on their failure to leave.
