Keeping known environmental notices in a seller document index
Maintain an organized index of environmental disclosures in Illinois to fulfill your legal duties and provide transparency to potential property buyers.
The short answer
Sellers have a legal obligation to provide specific environmental notices, including lead-based paint and radon information, to potential buyers. Create a document index to track these notices. This ensures you meet your disclosure requirements under the Residential Real Property Disclosure Act and federal lead rules, reducing your liability and streamlining the sales process.
Structuring Your Disclosure Index
Organize your records by category: lead-based paint, radon, and general material defects. Include copies of the Illinois Disclosure of Information on Radon Hazards and the Lead Warning Statement. This index serves as a repository for all legally required notices.
Worksheet: Create a folder labeled 'Required Disclosures.' Include a checklist of each document with the date it was provided to the buyer.
Lead-Based Paint Compliance
For pre-1978 properties, you must provide all available lead-related reports and the mandatory warning statement. Failure to comply can result in EPA penalties. Keep these records for at least three years after the sale.
Worksheet: Log each lead-based paint report you possess. Note whether it was an assessment, a test result, or a clearance report.
Managing Radon Disclosures
The Illinois Radon Awareness Act mandates providing the IEMA-OHS pamphlet. This is an informational requirement, separate from the general material defect disclosure. Track that this pamphlet was delivered along with your other documents.
Worksheet: Keep a signed receipt or a log entry confirming delivery of the radon pamphlet to the buyer.
Updating for New Information
If you become aware of a material defect or environmental issue after delivery, you must provide a written supplemental disclosure before closing. This avoids liability for knowingly providing false or incomplete information.
Worksheet: Include a 'Supplemental Disclosure' page in your index. If an issue arises, record the date of discovery and the date the supplement was shared with the buyer.
