When Can a Landlord Raise Rent in Illinois?

Landlords in Illinois can raise the rent at any time, as long as they comply with the following:

  • Give the tenant reasonable notice
  • Aren’t raising rent for discriminatory reasons
  • Wait until the end of the lease term (unless otherwise specified in the lease)
  • Are not raising the rent after a tenant action that’s protected by the state landlord retaliation law

When Can’t a Landlord Raise Rent in Illinois?

Landlords in Illinois may not raise the rent if:

  • It is during the middle of a lease’s fixed term (unless stated otherwise in the lease agreement)
  • The increase is applied in a way that discriminates against one of the protected classes specified in the Fair Housing Act
  • The increase is applied in a way that violates the Illinois Human Rights Act, by discriminating against a tenant’s age, military status, arrest record, pregnancy, history of domestic violence, or source of income

  • Joining or organizing a tenants’ group or union
  • Testifying in court against the landlord
