McLean County, IL Parking Rules: Driveway Rules (2026)

McLean County Zoning Code § 350-65D states that off-street parking spaces open to the sky may be located in any yard except front yards and side yards adjoining a street in the A Agriculture District, R-1 Single-Family Residential District, and R-2 Two-Family Residential District. The rule targets driveway aprons and gravel pull-offs sited ahead of the house line rather than beside or behind it; a carport or garage set back from the street front is unaffected because the prohibition only reaches open-to-the-sky spaces in the yard itself.

Section 350-66 layers on surfacing and design standards. Any open parking area with more than eight spaces must be graded and paved with asphalt, concrete, or asphaltic concrete as approved by the County Engineer, though lots tied to a special event permit or a not-for-profit agricultural demonstration are excused. Driveways crossing the public right-of-way line cannot exceed 25 feet in width in a residential district or 35 feet in a commercial or industrial district, unless the County Engineer, the township road district commissioner, or IDOT requires otherwise.

Required spaces must measure at least nine feet wide and 20 feet long, with seven feet of vertical clearance if enclosed. Because McLean County zoning governs only the unincorporated county, none of this reaches a driveway inside Bloomington or Normal, which enforce their own municipal codes. The Director of Building and Zoning administers these standards and reviews site plans before a construction permit issues.
