WALDO is an online asbestos and lead certification database offered for public access.

Lead-Free / Lead-Safe Registry

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.

Lead-Safe Wisconsin Home - More information about lead-based paint, lead-safe renovation and lead abatement, lead training and certification requirements, childhood lead-poisoning in Wisconsin and the health effects of lead exposure, and how to find a certified contractor or how to conduct lead-safe work.

Visit our Contractors Corner if you are a contractor who may have to deal with lead-based paint on your jobs.  If your work disturbs paint and the home or building was built before 1978 you may be disturbing lead-based paint.
