A New York immediate notice to quit is used by landlords to begin the process of evicting a tenant who has used the rental property to run an illegal business or perpetuate illegal activity. Examples of illegal businesses include prostitution and the production and/or sale of illegal narcotics. The notice relays the illegal actions that the tenant has committed and informs them that their lease is terminated. If the tenant does not move off the property immediately, the landlord can start legal action to have them removed by court order.
