Mount Prospect, IL Parking Rules: Commercial & Oversized Vehicles (2026)

Section 14.2203 A of the Mount Prospect Village Code controls commercial vehicle parking in residential districts, and it applies number, location, size, storage and signage limits at once. The rule does not apply to commercial vehicles conducting business at a location within a residential district.

Number and location: one commercial vehicle on a single-family detached lot, and one commercial vehicle per residential unit in a multiple-family development. The vehicle goes in a fully enclosed garage or in the rear or side yard only. A front yard space is allowed only when the property is developed so that rear or side yard parking is physically prohibited, and then the vehicle sits as near the front of the garage as is physically possible. In every case the surface must be an approved hard surface.

Size: no more than seven feet (7') high, seven feet (7') wide with mirrors excluded, and nineteen feet six inches (19'6") long, with snowplow blades excluded from the length.

Exterior storage: no trailers or other attachments on the rear, snowplows allowed on the front during the winter season, no equipment, storage racks or materials on the sides, and top racks no taller than eighteen inches (18"), with the whole vehicle no taller than eight feet (8'). Equipment other than a permanently attached tool box cannot show above the pickup truck bed, and loose landscaping material or debris cannot be carried in the trailer or bed. Signage is limited to the front door panels only.

Other prohibitions: a vehicle with a refrigeration unit or motorized compressor, or with more than four (4) wheels, is barred unless it is parked in a garage in such a manner that the unit is not audible outside. Commercial trailers must be parked in a fully enclosed garage at all times. A vehicle on site for work purposes cannot be parked more than ten (10) consecutive hours and can never be parked overnight.
