Summary

Jefferson County bans letting your property become a breeding place for rats, flies, mosquitoes or other vermin. The county health officer investigates complaints and can order cleanup, with forfeitures of $50 to $500 per offense for anyone who lets the condition continue in unincorporated Jefferson County.

These county ordinances apply to unincorporated areas of Jefferson County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Public nuisances are prohibited in the county. The term "public nuisance" includes, but is not limited by enumeration of, the following: ... (5)Food or breeding places for vermin, insects, etc. Accumulations of decayed animal or vegetable matter, trash, rubbish, garbage, rotting lumber, bedding, packing material, scrap metal, animal and human fecal matter, or any substance in which flies, mosquitos, or disease-carrying insects, rats or other vermin can breed, live, nest or seek shelter.

Full Breakdown

Under Jefferson County Code § 18-72(5), a public nuisance includes any accumulation of decayed animal or vegetable matter, trash, rubbish, garbage, rotting lumber, bedding, packing material, scrap metal, or animal and human fecal matter in which flies, mosquitoes, disease-carrying insects, rats or other vermin can breed, live, nest or seek shelter. Section 18-70 makes it unlawful to erect, cause, continue or permit any public nuisance in the county, and § 18-71 puts the duty on both tenants and property owners to keep their property nuisance-free and to abate any nuisance found on it.

The county health officer, defined in § 18-69 as the public health department director, or a designated representative investigates every reported nuisance under § 18-75 and issues a written cleanup order specifying the corrective action and a deadline that can run from 24 hours to 30 days or more depending on severity. If the order is ignored, the health officer can issue a citation under Wis. 0113 or refer the matter to the district attorney or corporation counsel for court action seeking a higher forfeiture or an injunction.

In an immediate health hazard, or where the responsible party refuses to comply, the county can abate the condition itself and bill the owner for the cost.

Violations & Fines

Section 18-76 sets a forfeiture of not less than $50.00 nor more than $500.00 per offense, plus surcharges, penalty assessment and the taxable costs of prosecution; the court may also grant injunctive relief. Each day a cleanup order goes unmet is a separate offense, and failure to pay a court-ordered penalty can mean jail in the county jail until payment, up to 90 days.
