Illinois Landlord's Seven-Day Notice is a notice used by landlords in the state of Illinois to inform a tenant that they are in violation of their lease agreement and must take corrective action or vacate the rental premises within seven days. This notice, also known as a Notice to Quit, demands that the tenant either remedy the violation or vacate the premises in seven days or a legal eviction action may be taken. This notice must be written in accordance with the Illinois Forcible Entry and Detained Act and state that the tenant has seven days to vacate the property or the landlord will file an eviction lawsuit. There are two types of Illinois Landlord's Seven-Day Notice: Cure or Vacate and Unconditional Quit. The Cure or Vacate Notice provides the tenant with an opportunity to correct the lease violation within the seven-day period. If the tenant fails to correct the violation, they must vacate the premises within the seven-day period or face eviction. The Unconditional Quit Notice requires the tenant to vacate the premises within seven days without any opportunity to correct the lease violation.
