The notice given by a landlord (owner) to a tenant to leave the premises (quit) either by a certain date (usually 30 days) or to pay overdue rent or correct some other default (having pets, having caused damage, too many roommates, using the property for illegal purposes, etc.) within a short time (usually three days). a notice to quit must contain certain information, such as: names of the persons to leave, whether their tenancy is by written or oral agreement, an amount of any financial delinquency and the period it covers, and to whom they should surrender the premises. if the tenant is month-to-month, a notice to quit without reference to default usually requires no reason. although state laws vary, generally the notice must be served personally on the tenant or posted in a prominent place like the front door with a copy sent by certified mail. such notice and failure of the tenant to quit (leave) is a requirement to bring a lawsuit for unlawful detainer (often referred to as “eviction”).
