Full Breakdown
Section 94.80 assigns nuisance enforcement by topic: the Health Department for property-maintenance and pest violations, the Sheriff's Office for public-safety nuisances, and Health, Planning/Building/Development, and the Sheriff jointly for everything else. Under section 94.81, an Enforcement Officer who confirms a violation issues a warning by posting, personal service, or mail, giving the owner at least seven days to cure it before a formal Notice of Ordinance Violation and administrative-adjudication hearing follow under section 94.82.
Violations & Fines
Ignoring a warning brings a Notice of Ordinance Violation, an administrative-adjudication hearing before a Lake County hearing officer, and a fine under the fee schedule; the county can also seek injunctive relief or abatement in circuit court.
