Mold Remediation Regulations in Illinois

Illinois does not require a statewide mold remediation license. However, the state has enacted mold awareness legislation, and contractors are expected to follow industry standards. Chicago and Cook County may have additional local requirements for mold remediation work. Homeowners should verify IICRC certification and insurance.

Seller Disclosure Requirements

Illinois requires sellers to complete a Residential Real Property Disclosure Report that covers known material defects including environmental conditions. Sellers must disclose known mold contamination and any history of remediation.

Insurance Coverage

Homeowner policies in Illinois typically cover mold from sudden water damage events such as pipe bursts. Basement flooding is a common mold trigger, and separate flood insurance may be needed. Many Illinois insurers offer mold endorsements for additional coverage.

Safety Considerations

Homes built before 1978 may contain lead-based paint. Federal EPA RRP rules require certified renovators when disturbing painted surfaces in older homes. Illinois has additional lead paint notification requirements for child-occupied facilities.
