Mount Prospect, IL Parking Rules: Driveway Rules (2026)

Section 14.2204 of the Mount Prospect Village Code sets the rules for single-family and attached single-family driveways, and Section 14.2401 defines a driveway as a paved surface used for access to a single-family residential property from the public right of way.

Layout: a minimum of two (2) parking spaces must meet the required setbacks of the zoning district, and the driveway must lead to an off street parking space or parking pad and cross the required front or exterior side yard essentially perpendicular to the street pavement. Circular or dual frontage driveways and driveways serving side load garages are exempt from that layout requirement. Minimum width is eight feet (8'). Parallel paving strips are permitted as an alternative to a paved driveway surface, with width measured from the outside edge of the pavement and including the space between strips. In a required front or exterior side yard, abutting parallel sidewalks and patios count toward driveway width.

Maximums: a driveway serving an attached or detached garage cannot exceed twenty six feet (26') wide, and it cannot encroach more than three feet (3') beyond the garage toward the front plane of the house. A driveway serving a three car attached garage can match the garage width, up to thirty three feet (33') within the first eighteen feet (18') of the garage front elevation, tapering to no more than twenty six feet (26') within eighteen feet (18'). Side load garage driveways are capped at twenty six feet (26').

Parking pads: a pad must be reached by a driveway serving an attached garage, can extend into required yards, must be at least eight feet (8') wide and no larger than two hundred (200) square feet, with adjacent sidewalks and patios counted in the area. Pads count toward the maximum driveway width.

Front yard paving is also capped by district. In R-1, total impervious surfaces cannot exceed forty five percent (45%) of the required front or exterior side yard (Section 14.905 C.2). R-X is thirty five percent (35%) under Section 14.805, and R-A is fifty percent (50%) under Section 14.1005.
