The Illinois Landlord's Five-Day Notice is a document that is served to a tenant for failure to pay rent or other breach of the lease agreement. The notice informs the tenant that they must pay the full amount of rent due or vacate the premises within five days. The notice must include the exact amount due, the date when the rent was due, the name of the landlord, the address of the premises, and a warning that failure to pay or vacate the premises within five days may result in eviction proceedings. There are two types of Illinois Landlord's Five-Day Notice: the Five-Day Notice to Pay Rent or Quit and the Five-Day Notice to Cure or Quit. The Five-Day Notice to Pay Rent or Quit is used when the tenant has failed to pay rent. The Five-Day Notice to Cure or Quit is used when the tenant has breached the lease agreement in a way other than failing to pay rent.
