The Idaho three (3) day notice to pay or quit is a letter warning tenants to either pay their rent or else be forced to vacate. There is no statue in Idaho specifying a grace period for late rent. Therefore, the landlord may serve notice to the tenant as soon as the individual fails to pay by the preestablished due date. If the tenant neither pays their overdue rent or vacates the dwelling within three (3) days of receiving notice, the landlord may seek to obtain a Writ of Restitution by filing an eviction lawsuit (a Writ of Restitution authorizes the sheriff to forcibly remove the tenant from the premises of the rental unit).
