Summary
In unincorporated Yellowstone County, a licensed and operable motor vehicle parked or stored in a front or side yard must sit on a surface prepared with asphalt or concrete. Rear-yard parking has no surface requirement at all. The rule applies to every residential zoning district under the Yellowstone County Zoning Code.
2. Licensed and Operable Motor Vehicles The following standards apply to the open storage and off-street parking of licensed and operable motor vehicles is an allowed accessory use subject to the following standards:
(a) This is an allowed accessory use for non-commercial vehicles . Parking and open storage of one licensed and operable motor vehicle used for commercial or business purposes is an allowed accessory use provided it does not exceed 12,000 pounds in G.V.W. (gross vehicle weight).
(b) Front or side yard parking or open storage shall be on a surface prepared with asphalt or concrete.
(c) Rear yard parking or open storage may be provided on any type of surface.
Full Breakdown
A of the Yellowstone County Zoning Code sets accessory parking standards for every residential zoning district in the unincorporated county, administered by the joint City-County Planning Division. Open storage or off-street parking of one licensed and operable motor vehicle is an allowed accessory use, and a single commercial or business vehicle qualifies too as long as it does not exceed 12,000 pounds gross vehicle weight. The surface requirement is where front yards get strict: front or side yard parking or open storage must be on a surface prepared with asphalt or concrete.
Bare dirt, gravel, or lawn does not satisfy it in those yard areas. Rear yards are treated differently: parking or open storage there may be provided on any type of surface, so gravel or turf is fine once the vehicle is behind the house. The code's stated purpose for the whole section is to keep parking from becoming the primary use of a residential lot and to make sure accessory parking, where it is allowed, follows the Zoning Code's standards rather than spreading unchecked across yards.
Recreational vehicles, boats, snowmobiles, ATVs, and similar equipment fall under a separate standard in the same section with different surface and setback rules, so a paved front-yard car space and an RV parked behind the house are governed by different subsections of 27-1307 even though both sit in a residential yard.
Violations & Fines
Violating the surface requirement is enforced under Article 27-1700's general penalties: Section 27-1704.G makes any Zoning Code violation a misdemeanor punishable by a fine up to the state statutory limit, up to six months in the county jail, or both, plus all costs and expenses. Each day the unpaved front-yard parking continues counts as a separate offense. The zoning coordinator can also issue a stop-use or stop-work order under Sections 27-1704.D and .E to halt the noncompliant use before it goes to court.
