Florissant, MO Parking Rules: Driveway Rules (2026)

Section 340.165 makes it unlawful to willfully operate a motor vehicle on or upon the yard or lawn of another person's real property within the City without that owner's or controller's permission. The ordinance defines yard or lawn as any portion of a property that is not paved with asphalt, concrete, gravel or similar material and is not intended for vehicle operation, so it targets unauthorized driving onto someone else's unpaved ground rather than a homeowner's own paved driveway; the paved-surface standards for a resident's own driveway sit instead in the zoning code, Chapter 405. To help enforcement when the driver isn't directly witnessed, the section presumes that whoever the vehicle is registered to in State records is the operator. The rule dates to Code 1980 §15-15.1 and CC 1990 §15-16. Because Section 340.165 sets no fine of its own, a violation is punished under the City's general penalty clause, Section 100.080.
