Home occupations are allowed as an accessory, incidental use of a home. In unincorporated McHenry County the operator must live in the dwelling, the business must be conducted entirely indoors, and it cannot alter the residential character of the property. Auto/small-engine repair and ready-made retail sales are prohibited.
McHenry County UDO § 16.56.050(I) treats a home occupation as secondary to residential use. It must be conducted within a principal or accessory structure (no outdoor operation or storage), produce no noise, odor, glare or vibration perceivable beyond the lot lines, and admit clients by appointment only. Crystal Lake's UDO similarly requires the use be clearly incidental and confined to the principal structure.
Operating a prohibited use or spilling business activity outdoors violates the zoning ordinance; the County can require the use to cease and, for conditional-use properties, revisit the permit. Cities enforce through their zoning/nuisance codes with fines.
