In unincorporated McHenry County, a resident may let a guest park or store one RV, trailer, or boat for no more than 60 days per year. Crystal Lake allows RVs on driveways with size limits.
The McHenry County Unified Development Ordinance (UDO) governs unincorporated land: a homeowner may host a single guest recreational vehicle, snowmobile, ATV, or trailer up to 60 days per calendar year, and RV storage is prohibited on any lot without an occupied dwelling. In Crystal Lake, RVs, boats, and trailers under 11 feet tall and 25 feet long may sit on a residential driveway; larger units must be stored in a side or rear yard. Municipalities (Crystal Lake, Woodstock, McHenry, Algonquin) each set their own limits, so check your city if you are not in unincorporated territory.
UDO and city zoning violations are nuisance/ordinance offenses; typical fines run from about $50 up to $750 per day until the vehicle is removed or properly stored.
