SCC 30.91R.050; SCC 11.06 (Ord. 25-021)
According to the Snohomish County Code (SCC) 30.91R.050, recreational vehicle (RV) is defined as a travel trailer, motor home, truck camper, or camping trailer that is permanently designed and used as temporary living quarters.
Snohomish County sets no specific paved-driveway or front-yard parking-surface rule for ordinary residents in its parking chapters. Vehicle parking is instead shaped by the large-vehicle ban in residential zones (SCC 11.05) and off-street parking standards in the development code (SCC 30.26).
It is unlawful to park or store a large commercial vehicle (GVWR 14,001 lbs or more) or trailer on any public road in or adjacent to an urban-residential area of unincorporated Snohomish County at any time (SCC 11.05.030). Elsewhere the limit is 12 hours per day.
Snohomish County restricts oversized and commercial-vehicle street parking rather than ordinary cars. Large commercial vehicles and trailers may not sit on a non-residential public road more than 12 hours in any 24-hour period, and are banned outright on urban-residential roads (SCC 11.05).
Snohomish County has no blanket overnight parking ban for passenger cars in unincorporated areas. The real limits are the 72-hour RV cap (SCC 11.06), the large-vehicle rules (SCC 11.05), and the 24-hour abandoned-vehicle threshold (SCC 10.36).
SCC 10.36.020
An "abandoned vehicle" for the purposes of this chapter means any vehicle left within the limits of any highway, or upon the property of another, without the consent of the owner of such property, or upon any public property, for a period of 24 hours or longer.
Snohomish County has no unique parking-chapter rule dedicated to EV charging for homeowners. EV-ready and charging-station requirements come from Washington's statewide building and energy codes adopted county-wide, not a special county ordinance.
A vehicle left on a Snohomish County highway or public property for 24 hours or longer is 'abandoned' (SCC 10.36.020) and may be removed by the Sheriff. Willfully abandoning one is a class 1 civil infraction plus removal costs; state impound follows RCW 46.55.
SCC 10.36.030
It is a prima facie presumption that any vehicle within unincorporated areas of Snohomish county, on private or public property or within the limits of any highway, is abandoned if the same is inoperable by reason of damage, neglect or the removal of parts therefrom and is unlicensed.

Snohomish County's large-vehicle parking chapter carves out active loading and unloading: a large commercial vehicle or trailer that would otherwise be barred from an urban-residential road may stop there while actively loading or unloading materials or passengers (SCC 11.05.030).
Oversized vehicles - anything with a GVWR of 14,001 lbs or more, plus commercial trailers and construction equipment - are banned from urban-residential public roads and limited to 12 hours per day elsewhere under SCC 11.05. RVs over the limit fall under the separate 72-hour RV rule (SCC 11.06).
