Full Breakdown
Lake County's Unified Development Ordinance treats garage sales as a temporary use permitted by-right in every zoning district of unincorporated Lake County: no temporary use permit is required. The tradeoff for skipping the permit is a hard cap: no more than two garage sales per zoning lot per calendar year, each running no longer than three consecutive days, and sales limited to daylight hours. This applies only outside incorporated municipalities; Waukegan, North Chicago, Highland Park, Gurnee, Libertyville and other cities/villages set their own garage-sale rules under their own codes.
Violations & Fines
No fine schedule is attached to this subsection; exceeding the two-sale annual cap or the three-day duration limit removes the by-right protection, making the sale an unpermitted temporary use enforceable by the Planning, Building and Development Department under the county's general zoning enforcement provisions.
