St. Louis County, MO Parking Rules: Driveway Rules (2026)

060(1) states that no person shall park or permit a vehicle to remain in the front yard of residential property unless the vehicle is parked on a paved driveway or designated parking area. Subsection 2 defines 'front yard' as the area between a road and a line parallel to the road intersecting the closest point of the residence, while the 'required front yard' is the deeper area set by the county Zoning Ordinance's front setback line; 'residential' covers any property zoned Non-Urban or Residential and any property actually used for residential purposes regardless of its zoning label.

Subsection 3 lets homeowners build a designated paved parking area adjacent to and contiguous with the driveway anywhere on the lot except inside the required front yard itself, though it can sit in a front yard that falls outside that stricter setback zone. In practice, gravel, grass, or dirt parking pads in front of a house are never allowed no matter where they sit, and even a paved pad is off-limits if it intrudes into the zoning ordinance's mandatory front setback. 020 extends to unincorporated St. Louis County and to county arterial roads, so it governs private-yard parking on unincorporated residential lots regardless of which road fronts the property.
