Full Breakdown
Lake County's zoning code sets fixed buffers for any adult-use cannabis dispensary sited in the unincorporated county: no closer than 250 feet to a forest preserve property line or land zoned residential, 500 feet to a daycare, residential care home, college, hospital, park, or library, and 1,000 feet to a public or private school. Distances are measured in a straight line between the nearest property lines, ignoring intervening structures. Dispensaries also need a standard 30-foot setback from all property lines and must sit at least 1,500 feet from any other dispensary. Waukegan, Highland Park, and other cities set their own separate rules.
Violations & Fines
Violating the buffer, setback, or spacing standards blocks conditional-use and site-plan approval from the county; a dispensary found out of compliance risks permit revocation and enforcement action by the Lake County Planning, Building and Development Department.
