Olympia, WA Parking Rules: Commercial & Oversized Vehicles (2026)

OMC Chapter 10.18, Truck and Trailer Parking in Residential Areas, applies to streets in the City of Olympia, Thurston County, Washington. OMC § 10.18.020 makes it unlawful to park or leave standing, on any street within a residential area or on the portion of a street abutting one, any of three things: a truck with a gross weight capacity in excess of nine thousand pounds, a trailer in excess of twenty feet in length, or a commercial vehicle having a width of eighty inches or more.

OMC § 10.18.010 supplies the definitions. A commercial vehicle is any vehicle whose principal use is the transportation of commodities, merchandise, produce, freight, animals or passengers for hire. A truck is any motor vehicle designed primarily for the transportation of property. A trailer is every vehicle without motor power designed to be drawn by or used with a motor vehicle, built so that no appreciable part of its weight rests on that vehicle, and the term excludes recreational vehicles such as travel trailers. The chapter defines a residential area as areas of the city zoned R1, R2 or RMH under Title 18, so confirm the zoning district of the block before relying on the rule.

OMC § 10.18.030 exempts any vehicle parked or left standing to load or unload persons or property, as long as the stop does not extend beyond the time necessary.

The chapter prints no fine of its own. OMC § 10.24.050 provides that failure to perform an act required or the performance of an act prohibited by Chapters 10.04 through 10.36 constitutes a traffic infraction, governed by RCW Chapter 46.63. Travel trailers and other RVs are covered instead by OMC § 10.16.030, which sets a 24-hour limit on City streets without a Parking Services permit and a $95.00 penalty, and RVs cannot be registered in the Residential Parking Program under OMC § 10.16.055(D)(2).
