Creates liability for parties that promoted lead-based paint for residential use with actual or constructive knowledge that such use would cause serious health hazards.

Allows causation in lead-based paint abatement actions to be proven without requiring evidence that a particular party applied specific paint to a specific residence.

Includes legislative findings documenting that lead exposure causes irreversible developmental harm in children, with no safe exposure level according to the CDC, WHO, and American Academy of Pediatrics.

Clarifies California's existing public nuisance law regarding lead-based paint in residential properties, building on prior court decisions including County of Santa Clara v. Atlantic Richfield Co. (2006) and People v. Conagra Grocery Products Company (2017).
