Illinois Lease Violation Notice — 10-Day Notice to Comply or Vacate (2026)

For material lease violations in Illinois, landlords serve a 10-day notice to comply or vacate under 735 ILCS 5/9-210. The tenant has 10 days to fix the violation or surrender the premises.

What to Include

  • Tenant's name and address
  • Specific description of the lease violation (cite the section)
  • What the tenant must do to cure
  • 10-day deadline
  • Date of service

Chicago RLTO — Additional Requirements

Chicago properties subject to the RLTO require the notice to include specific disclosures about tenant rights. The 10-day period is standard under state law, but Chicago courts apply heightened scrutiny to notice content.

Unconditional Termination

For severe violations — criminal activity, substantial property damage, endangering other residents — Illinois permits an unconditional notice to vacate with a shorter period depending on lease terms.
