Summary
Lake County treats renting out living quarters the Health Officer finds unfit for habitation as a public nuisance, but runs no scheduled rental-inspection or licensing program: enforcement is complaint-driven only, under § 94.06(B) of the county's nuisance ordinance.
Renting or leasing unfit living quarters. It is a public nuisance to rent or lease quarters for human habitation that, as determined by the Health Officer, are unfit for human habitation, or present/contain conditions that are detrimental to the health of the inhabitants, including but not limited to: a lack of potable water supply or a lack of adequate means of wastewater disposal.

Full Breakdown
Lake County runs no rental-registration or scheduled-inspection program. Instead, under the Public Nuisance Ordinance, renting living quarters the Health Officer determines unfit for human habitation, for conditions like missing potable water or inadequate wastewater disposal, is itself a public nuisance (§ 94.06(B)). The Health Officer investigates only after a complaint, then issues a Warning of Ordinance Violation and, if unresolved, a Notice of Ordinance Violation heard through administrative adjudication (§§ 94.50-94.66) or cited to the 19th Judicial Circuit Court. The rule reaches unincorporated Lake County and any incorporated area under county enforcement authority (§ 94.02); Waukegan, Highland Park, Gurnee, and Libertyville otherwise enforce their own housing codes.
Violations & Fines
Each day a rental-habitability nuisance continues is a separate offense; fines run through administrative adjudication or Circuit Court, capped at $1,000 per violation under the code's general penalty (§ 10.99).
