Idaho Eviction (Unlawful Detainer) Notice

Idaho Code 6-303 sets the grounds and notices for unlawful detainer. For default in rent, the landlord must serve 'three (3) days' notice, in writing, requiring its payment, stating the amount which is due, or possession of the property.' For breach of other lease covenants, the landlord gives 'three (3) days' notice, in writing, requiring the performance of such conditions or covenants, or the possession.' Separate provisions cover holdover after lease expiry (with required termination notice for tenancies at will), assignment/subletting/waste (three days' notice to quit), and controlled-substance activity on the premises. If the tenant fails to cure or vacate within the three days, the landlord may file an unlawful-detainer action to regain possession.

No specific statutory fine. A tenant who fails to pay, cure, or vacate within the three-day notice period can be sued for unlawful detainer under Idaho Code 6-303, leading to a court judgment for possession (and potentially rent, damages, and costs) and removal by the sheriff.
