Illinois Daycare License Renewal:
DCFS Rule 407 Radon Testing

If you’re a daycare center in Illinois preparing for your three-year license renewal, the DCFS Rule 407 process can feel overwhelming—especially when it comes to documentation and environmental testing. Fortunately, Real Inspection Services helps you stay compliant with certified, DCFS-ready radon testing.

Real Inspection Services, an approved radon contractor with the Illinois DCFS, helps you stay on track throughout the renewal process by ensuring all requirements and deadlines are met. Our licensed team performs accurate, compliant testing and provides the proper documentation required by the State of Illinois. With safety handled, you can stay focused on what matters most—caring for the children and families you serve.

Understanding the DCFS 3-Year Renewal Process

According to the Illinois Department of Children and Family Services (DCFS), daycare centers must renew their license every three years under DCFS Rule 407.

To help you prepare, here’s a simple timeline:

  • First, 6 months before expiration, DCFS sends your renewal application.
  • Next, 3 months before expiration, you must submit your completed renewal form with all supporting documentation.
  • After submission, DCFS conducts a licensing study and issues your updated certificate.

Required Documentation for Renewal

Your renewal packet must include:

  • Proof of Radon Test: Conducted within the past 3 years by a state-licensed professional, as required by the Illinois Emergency Management Agency (IEMA) Radon Division.
  • Completed Renewal Application: With current facility details and signature.
  • Ongoing Compliance Records: Annual inspection reports and safety documentation.

If your last radon test is older than three years or missing altogether, it will delay your renewal approval — but Real Inspection Services can help you get back on track quickly.

    and new expiration date.
