McLean County, IL Parking Rules: RV & Boat Parking (2026)

McLean County's zoning ordinance treats boats, boat trailers, camping trailers, and converted buses or trucks as accessory residential uses under § 350-43A(3)(l), meaning the storage right exists only alongside a lawful principal residential use in the unincorporated county, not inside Bloomington or Normal, which enforce their own municipal codes. The ordinance limits where the equipment can sit: a private garage, a side or rear yard, or a driveway, but only if the driveway parking spot sits behind the lot's required front-yard setback line, so storage forward of that line in the front yard itself is not allowed.

The same subsection bars using a stored recreational vehicle as a dwelling: nobody may live or sleep in it while it sits on the property for more than 14 days total in a calendar year, a limit aimed at preventing RVs from becoming informal second residences. The county folds this into its broader accessory-use standards in § 350-43A(5), which also require accessory structures to respect the district's setback, height, and lot-coverage limits, so a boat or trailer stored under a carport still has to clear the interior setbacks that apply to accessory structures generally.

The Director of Building and Zoning administers the use table and can require a permit if the storage arrangement drifts into a different accessory use. Violations of Chapter 350's use standards, including this storage rule, are petty offenses under § 350-22, punishable by a fine of up to $500, with each week the violation continues counting as a separate offense enforceable in Circuit Court.
