Who is covered by Illinois landlord-tenant laws?

Landlord An owner of property who rents it out to a tenant -tenant laws cover adults living in property belonging to someone else who:

  • Have a spoken (oral) or written agreement to live in the property, and
  • Are not married to a person who owns the property.

Landlord-tenant laws:

  • Are not based on personal relationships (learn more about Evicting friends, unmarried partners, and family members), and
  • Do not prevent law enforcement officers from removing people for criminal trespass (learn more about Trespassers and squatters).

What is a written eviction notice?

A written eviction notice or demand is a legal paper that explains one of the following situations:

  • Rent was not received on time (learn more in Dealing with unpaid rent),
  • The landlord An owner of property who rents it out to a tenant believes the tenant A person who rents a space broke rules or was involved in criminal activity (learn more in Addressing lease violations),
  • The lease is ending and will not be renewed (learn about Ending a lease), or
  • A person living in someone else's property has no legal right to be there at all (learn more in Trespassers and squatters).

In public housing, a written eviction notice must also state whether the tenant has the right to a grievance hearing to see what they can do to avoid eviction. If the tenant does not have the right to a grievance hearing, the notice must say why.

To avoid eviction, do not ignore a written eviction notice, even if it looks incorrect. Use Get Legal Help to find local resources or contact:

  • Eviction Help Illinois statewide at (855) 631-0811, or
  • Cook County Legal Aid for Housing and Debt in Cook County at (855) 956-5763.

  • A lease that is ending and will not be renewed, sometimes called a 30-day notice (learn about Ending a lease), and
  • Situations where people have no legal right to live in the property at all, known as a demand for immediate possession (learn about Trespassers and squatters).

Describing notices as 5-day, 10-day, and 30-day may be confusing. Longer notice periods may be required by:
