Summary

A junked trailer or junked motor vehicle left on private property in unincorporated St. Louis County for more than 72 hours is a declared public nuisance under Section 1216.080, subject to a five-day notice, an owner's right to a hearing before the Superintendent, and county removal at the owner's expense if the nuisance isn't abated.

City-specific rules exist: Florissant has its own abandoned vehicles rules that differ from St. Louis County's county-level regulations. If you live in Florissant, check the city-specific page instead.

No person shall park, store, leave or permit the parking, storing or leaving of a junked trailer or junked motor vehicle or parts thereof upon any private property within the County for a period of time in excess of seventy-two (72) hours. Provided, however, this chapter shall not apply to any vehicle enclosed within a building, nor to a junkyard or salvage business lawful under the zoning ordinances of St. Louis County. Provided, further, that nothing in this ordinance shall be construed to prevent a person from keeping on the person's private property for a period of time not to exceed thirty (30) days one junked trailer and junked motor vehicle for the purpose of making minor repairs or modifications to it, nor to prevent a person from keeping a motor vehicle of historic interest, as defined in RSMo 301.131. The presence on private property of one or more junked trailers or junked motor vehicles or parts thereof contrary to the preceding subsection is hereby declared to be a public nuisance which may be abated as such in accordance with the provisions of this chapter.

Full Breakdown

131. 100 requires the county Superintendent to notify both the vehicle's owner, if known, and the property owner or occupant at least five days before the compliance deadline, either by mail or by leaving notice at the residence and on the vehicle itself; that notice must cite the violation, order removal within five days, and advise of the right to a hearing. 120 stays the clock until the Superintendent rules, and if a violation is found, the Superintendent orders removal and can set the terms.

110 lets the Superintendent enter the property and remove the vehicle, and interfering with that removal is itself a separate offense. 090, and the county can pursue payment against either.

Violations & Fines

Section 1216.150 makes violating Section 1216.080, as well as Sections 1216.060 and 1216.110, a misdemeanor punishable by a fine of up to $500, with 'each act in violation of any of the provisions of this chapter' treated as a separate offense, so a vehicle left in place across multiple notice periods can generate more than one charge. Interfering with the Superintendent's authorized removal under Section 1216.110 is a separate violation subject to the same penalty.

Frequently Asked Questions

How long can a junked car sit in my yard in St. Louis County?
No more than 72 hours under Section 1216.080, unless it's inside a building, part of a lawful junkyard, or being minor-repaired, in which case you get up to 30 days. A historic vehicle under RSMo 301.131 is exempt entirely.
What happens after the county notices my junked vehicle?
The Superintendent must give at least five days' written notice citing the violation and ordering removal, per Section 1216.100. You can request a hearing within that period; if you don't, or if the Superintendent finds a violation after a hearing, the county can enter the property and remove the vehicle under Section 1216.110.
Who pays if the county tows my junked vehicle?
Both the vehicle's owner and the property owner or occupant are jointly and individually liable for the cost of removal, storage and any advertising expense under Section 1216.090, and the county can collect from either party.
