St. Louis, MO Parking Rules: Commercial & Oversized Vehicles (2026)

Under § 17.30.020, no truck or bus may be parked on a public street where the abutting land sits in the "A," "B," "C," "D," "E," or "F" use zoning district; a vehicle parked in violation is declared a nuisance and an unlawful street obstruction, and the same ban extends to private streets under the same lettered districts. A separate clause bars tractors, truck-tractors, trailers and construction equipment from being placed or stored on any public street or alley without a Director of Streets permit. The rule targets commercial equipment, not personal trucks: § 17.30.025 lets noncommercial pickups park on residential streets if the bed is clear of debris or has a factory cover, and § 17.30.020 exempts commercial vehicles parked within 50 feet of the "F"-zoned business that owns them, or vehicles actively loading, unloading or servicing.
