Lead-Free/ Lead-Safe Registry
DHS maintains the Wisconsin Lead-Free/Lead-Safe Property Registry. 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. Click here for more information about the registry.

If you are a contractor whose work disturbs paint in homes or other buildings built before 1978, you may be disturbing lead-based paint. Click here for information on your responsibilities when conducting this work.
