HB4887

Requires sellers of existing dwellings to obtain an energy audit with a HERS Index Score before transferring title.

Illinois HB4887 mandates that sellers of existing dwellings obtain an energy audit resulting in a Home Energy Rating System (HERS) Index Score before transferring title. The audit must be conducted by a RESNET-certified Home Energy Rater and include on-site diagnostic testing. The HERS score and report must be disclosed to buyers and posted in the dwelling. Exemptions apply to newly constructed dwellings, foreclosures, family transfers, probate estates, and marital settlement agreements. Non-compliance may result in a civil penalty and invalidate the property transfer.
