Full Breakdown
Clackamas County does not have a length-specific residential oversized-vehicle ban, but Code 7.01.020(F) requires that any parked vehicle leave at least 18 feet of unobstructed roadway for other vehicles, and 7.01.020(J) prohibits parking that impedes traffic or obstructs a fire-apparatus access road, both of which practically limit large RVs, buses and trailers on narrow county roads. In residential zones, Code Enforcement requires approval for large trucks over 11,000 pounds GVW. Incorporated cities frequently add explicit size/length caps for street parking, so check the city if inside one.
Violations & Fines
Sheriff parking citation for blocking the roadway; boot/tow if it obstructs traffic or fire access; zoning action for an over-11,000-lb truck in a residential zone.
