Under Chapter 151 (UDO) and accompanying Zoning Maps, the unincorporated areas of Lake County are divided into Zoning Districts. The UDO establishes, within each district, the uses (i.e. a single-family house or a commercial establishment) that are permitted, allowed conditionally, or prohibited. The UDO also establishes standards (i.e. parking or landscaping requirements) for the uses. In addition, the UDO contains regulations relating to:
Density and dimensional (height and setback) standards
site capacity, site plan review and natural resource protection
