Access the Wisconsin Lead-Free/Lead-Safe Property Registry that provides information about state Registered Lead-Free and Lead-Safe properties. Properties in the Registry include both residential and child-care facilities where an inspection found the property to be entirely free of lead-based paint (Lead-Free) or free of lead-based paint hazards (Lead-Safe). Only properties inspected by a state certified Lead Inspector, Risk Assessor, or Hazard Investigator qualify for inclusion in the statewide registry.
You may search the registry by city name for a list of all registered properties in that city, or by property address if your interest is in a specific property.
