Full Breakdown

West Allis Revised Municipal Code § 7.25 lists 'lacks working smoke detectors or carbon monoxide detectors' as one of the specific 'Inhabitability Conditions' that make a dwelling a per se human health hazard under Wis. Stat. § 254.59. The city's Health Department can act on that designation the same way it acts on missing heat, plumbing, or electrical service: treating the missing CO detector as an unsanitary/uninhabitable condition subject to the city's nuisance-abatement and health-hazard enforcement process. Chapter 7's general penalty section, § 7.99, sets a forfeiture of up to $500 for violating any provision of the chapter.

Violations & Fines

Failing to maintain a working carbon monoxide detector is a per se human health hazard under § 7.25; violating any Chapter 7 provision carries a forfeiture of up to $500 under § 7.99.
