Jurisdiction and research scope
Unincorporated Lewis County, Washington only. Incorporated cities and towns, tribal lands and separately administered public lands require their own governing rules. Urban growth areas may use municipal codes under interlocal agreements. County public health jurisdiction can extend beyond county zoning jurisdiction. Current official Code Compliance FAQ and codified LCC 17.144.050, reflecting Ordinance 1348 (2023), read November 6, 2026. The FAQ cites LCC 15.25.060(3), 15.25.080(2) and 8.40.020(a).

Lewis County RV parking at a glance
| Location or use | What to check |
|---|---|
| Driveway / yard | Obtain county-confirmed parcel authority and the required trailer placement permit for longer occupied use. Confirm parcel setbacks, access, critical areas and any shoreline or floodplain restrictions. |
| Street / loading | The private-property rule does not authorize parking or camping on a public road. No independent extended loading exception is established by these sources. |
| Sleeping / utilities | Beyond 60 days: approved septic, water and trailer placement permit. Park/campground 210-day rule is separate. Approved septic and water supply are required beyond 60 days; electrical and other approvals remain separate. |
Occupancy beyond 60 days
The county’s Code Compliance FAQ says RV occupancy exceeding 60 days requires an approved septic system, approved water supply and an approved trailer placement permit. The 60-day threshold is not a blanket approval for every shorter stay. Ask the county about zoning, the actual site and whether a permit is required for the proposed arrangement.
Campgrounds have a different clock
LCC 17.144.050 limits the same party at an RV or tent camping site to 210 consecutive days. One caretaker, ranger, manager or similar accommodation has a separate exception. Parks allowing longer stays must meet the mobile-home-park chapter. The campground figure does not authorize 210 days of private-yard living.
Confirm which authority governs
The county FAQ distinguishes countywide health authority from municipal land-use codes. Cities follow their own ordinances, and urban growth areas may operate under interlocal arrangements and municipal standards. Confirm the authority for the parcel, plus setbacks, floodplain, shoreline, access and utility approvals. Unoccupied storage and roadway loading remain separate questions.
Who to contact for your setup
Ask Lewis County Planning or Code Enforcement to confirm jurisdiction, the actual parcel or road, vehicle classification, position, duration and intended use. Obtain the required road, building, electrical, plumbing or wastewater approvals before relying on a parking exception. Easements, HOA rules and leases remain separate. Start with the official rule or permit guidance.
Use the Lewis County parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
