Illinois lead mitigation notice: landlord 30 / 90-day deadlines

Short answer: An Illinois lead mitigation notice means an inspection found a lead hazard in your unit. Under the Lead Poisoning Prevention Act you must fix (mitigate) it within 30 days if the unit was inspected because of an elevated blood lead level in a child or pregnant person, or if a child 6 or younger or a pregnant person lives there; otherwise within 90 days (410 ILCS 45/9(5)).

Step by step after the notice arrives

  1. Read the notice and the inspection report. The agency (the Illinois Department of Public Health or its delegate agency) must tell you the deadline and describe mitigation that meets the Act (Sec. 9(1)).
  2. Optional: submit a mitigation plan to the agency for review and approval (Sec. 9(4)).
  3. Hire licensed help for paint-disturbing work. Mitigation that destroys or disturbs a lead-bearing surface must be done by a licensed lead abatement contractor using licensed supervisors or workers, unless the Department’s rules or a case-by-case waiver allow otherwise (Sec. 9(3)). The contractor must give you and the tenant the lead pamphlet no more than 60 days before work starts (845.25(c)).
  4. Running late? Ask for an extension before the deadline. The agency may extend it if you are making substantial progress, cannot get a licensed contractor in time, or are waiting on mitigation-plan approval (Sec. 9(6)).
  5. Follow-up inspection. After the deadline the agency re-inspects. If the hazard is fixed you get a certificate of compliance; if not, you get a deficiency notice and a mitigation order with specific actions and a new date, which can include abatement (Sec. 9(7)).

What counts as “mitigated” for lead paint

For a paint or surface-coating hazard, the Act treats it as mitigated when the surface no longer gives off hazardous chips, flakes or dust; or children can no longer reach or chew it; or the coating is removed or covered or child access is otherwise prevented as the Department prescribes (Sec. 9(2)).
