What a valid Illinois rent increase notice includes

  • • Full names of all tenants and the rental property address
  • • The landlord’s name and mailing address
  • • The current rent, the new rent, and the exact date the increase takes effect
  • • Service at least 30 days before the effective date (735 ILCS 5/9-207 (by analogy))
  • • A certificate of service recording how and when the notice was delivered — courts routinely ask for this
