Fond du Lac County, WI Building Safety: Lead Paint (2026)

Fond du Lac County Code § 30-244 flatly prohibits lead hazards: no owner of any premises shall create or allow to exist on the premises any lead hazard, and this article applies countywide, in both incorporated and unincorporated areas, under § 30-243, unlike most of the county's other property regulations, which reach only the unincorporated towns. The code enforcement office triggers an investigation once a child under six who occupied the premises is identified with lead poisoning or lead exposure; the office conducts a risk assessment, can remove samples for lab analysis, and if the owner refuses entry, can seek a warrant.

Once the office notifies an owner in writing that a lead hazard exists, § 30-244 gives the owner 30 days to hire a certified lead company and submit a written abatement plan. If no plan is submitted in that time, § 30-245 requires the office to post an eight-by-ten-inch warning placard reading "Warning! Lead Poisoning Hazard, Danger to Children" on every outside entrance door, removable only once the property is cleared under § 30-249. Section 30-247 bans specific lead-paint removal methods outright, including open-flame burning or torching, dry scraping, uncontained hydro-blasting, methylene chloride strippers and heat guns above 1,100 degrees Fahrenheit.

10 Wis. Admin. Code certification and get office approval of the plan before starting work, and a post-abatement clearance inspection must show the property meets the clearance dust-wipe standards, such as 40 micrograms per square foot or less on a floor, before the placard comes down.
